Description

The present invention relates to a vehicle safety control device that controls the opening and closing of a luggage compartment.

Some vehicles, such as trucks, are equipped with a luggage compartment behind the driver's seat for loading luggage. For example, Patent Document 1 discloses a vehicle equipped with a wing-type luggage compartment. In such a wing-type luggage compartment, the wing opens and closes in the vehicle width direction. By opening in this manner in the vehicle width direction, the driver or worker can load and unload luggage from the vehicle width direction.

JP 2004-230943 A

However, there is a possibility that the driver may not realize that the luggage compartment is not completely closed and may continue to drive the vehicle. In addition, there is a possibility that the luggage compartment opening/closing switch may malfunction due to some kind of impact while the vehicle is moving, causing the luggage compartment to open while the vehicle is moving.

In view of the above, the problem to be solved by this application is to provide a vehicle safety control device that can prevent the vehicle from traveling with the luggage compartment open.

The present invention has been made to solve at least some of the problems described above, and can be realized in the following aspects or application examples.

(1) The vehicle safety control device according to this application example includes an opening/closing information acquisition unit that acquires information on whether the luggage compartment of the vehicle is open or closed, a shift operation unit that can select a shift range for the vehicle including a range in which driving power can be transmitted and a range in which driving power cannot be transmitted, a parking brake that applies braking to maintain the vehicle in a parked state, and a control unit that performs driving prohibition control to prohibit at least one of changing the shift range to a range in which driving power can be transmitted by the shift operation unit and releasing braking by the parking brake when the opening/closing information acquisition unit acquires information on the luggage compartment being open.

In other words, if the luggage compartment is open, the shift operation unit and/or the parking brake are locked to prevent the vehicle from being driven. This makes it possible to prevent the vehicle from being driven with the luggage compartment open.

(2) In the application example of (1) above, the control unit may mechanically prohibit the shift range selection operation by the shift operation unit as a driving prohibition control that prohibits the shift range of the vehicle from being changed to a driving power transmission range. By mechanically prohibiting the shift range selection operation by the shift operation unit in this manner, it is possible to reliably prevent the shift range from being changed and to easily allow the driver to recognize that the shift operation is prohibited.

(3) In the application example of (1) above, the control unit may invalidate a signal indicating the shift range selected by the shift operation unit as a driving prohibition control that prohibits the shift operation unit from changing the shift range to a driving power transmittable range. In this way, electrically prohibiting the shift operation unit from selecting the shift range makes it possible to easily prevent the shift range from being changed.

(4) In any of the application examples of (1) to (3) above, the vehicle may further include an opening/closing switch that issues an instruction to open or close a luggage compartment of the vehicle, and the control unit may perform an opening prohibition control that prohibits the opening/closing switch from opening the luggage compartment when at least one of the following conditions is satisfied: when the driving power transmittable range is selected by the shift operation unit, and when the parking brake is in a released state. In other words, when the driving power transmittable range is selected or the parking brake is in a released state, the vehicle is in a driveable state, and therefore, by prohibiting the opening of the luggage compartment when in such a state, it is possible to prevent the vehicle from driving with the luggage compartment open.

(5) In the application example of (4) above, a vehicle speed detection unit that detects the vehicle speed of the vehicle may be further provided, and the control unit may perform the open prohibition control even when the vehicle speed detected by the vehicle speed detection unit is equal to or greater than a predetermined vehicle speed. In this way, by determining the vehicle's traveling state from the vehicle speed as well, it is possible to more accurately detect the traveling of the vehicle and more reliably prevent the vehicle from traveling with the luggage compartment open.

(6) In the application example of (4) or (5) above, when the control unit acquires the open information of the luggage compartment by the opening/closing information acquisition unit while the open prohibition control is being executed, the control unit may invalidate the acquired open information. In this way, when the control unit acquires the open information of the luggage compartment despite the execution of the open prohibition control of the luggage compartment, the open information is judged to be a false detection and is invalidated. This makes it possible to prevent malfunctions of other devices based on the open information due to a false detection, and more reliably prevents the vehicle from traveling with the luggage compartment open.

(7) In any of the application examples of (1) to (6) above, the driving power transmission impossible range may include a neutral range. This makes it possible to prevent a vehicle in which the driving power transmission impossible range includes the neutral range from being driven with the luggage compartment open.

(8) In any of the application examples of (1) to (7) above, the range in which driving power cannot be transmitted may include a parking range. This makes it possible to prevent a vehicle in which the driving power cannot be transmitted range includes the parking range from being driven with the luggage compartment open.

(9) In any of the application examples of (1) to (8) above, the luggage compartment may have wings that open and close at least the sides. This makes it possible to prevent a vehicle having wings that open and close the luggage compartment from traveling with the wings 9 open.

(10) The safety control device of the vehicle according to this application example includes an open/close switch that issues an instruction to open or close the luggage compartment of the vehicle, a shift operation unit that can select a shift range of the vehicle including a range in which driving power can be transmitted and a range in which driving power cannot be transmitted, a parking brake for maintaining the vehicle in a parked state, and a control unit that performs an open prohibition control that prohibits the opening of the luggage compartment by the open/close switch when at least one of the following conditions is satisfied: the range in which driving power can be transmitted is selected by the shift operation unit, and the parking brake is in a released state.

In other words, when the driving power transmission range is selected or the parking brake is released, the vehicle is in a driveable state, so by prohibiting the opening of the luggage compartment when in such a state, it is possible to prevent the vehicle from driving with the luggage compartment open.

The following describes one embodiment of the present invention.

Figure 1 shows an overall perspective view of a truck (hereinafter referred to as a vehicle) according to one embodiment of the present invention.

The vehicle safety control device according to this embodiment can be applied to vehicles equipped with a luggage compartment that can be opened and closed, but here we will explain the case where it is applied to a so-called wing-type truck that has a wing-body type van body (luggage compartment).

As shown in FIG. 1, the vehicle 1 is a cargo vehicle with a wing-body type luggage compartment 3 mounted on the rear of the vehicle body 2. An engine (not shown) is mounted on the front of the vehicle body 2, and a cab 4 including a driver's seat is located above it.

The luggage compartment 3 has a rectangular parallelepiped shape that is long in the front-to-rear direction of the vehicle, and includes a floor member 5 that forms the floor surface, a front wall 6 that forms the front surface, a rear frame 7 that forms the rear surface, and a rear door 8 that opens and closes the opening formed by the rear frame 7. In addition, the luggage compartment 3 has a pair of left and right wings 9 that form the top and side surfaces, and a flap 10 that forms the lower part of the side surface.

When closed, the wing 9 has an L-shaped cross section, consisting of a roof portion 9a that corresponds to the left-right half of the top surface of the luggage compartment 3, and a side wall portion 9b that is from the roof portion 9a to the tailgate 10. In this embodiment, the wings 9 are provided symmetrically, and the following description focuses on the left wing.

The wing 9 can be opened and closed from the side to the top of the luggage compartment 3 by rotating vertically around a center rail 11 that extends in the fore-and-aft direction of the vehicle at the center of the top surface of the luggage compartment 3. The tailgate 10 can also rotate vertically around the side edge of the floor member 5 as a fulcrum. When the wing 9 is closed and the tailgate 10 is positioned at the upper side in the vehicle height direction, the side of the luggage compartment 3 is closed. The wing 9 may be of a type that opens and closes only on one side in the vehicle width direction.

The wing 9 is driven to open and close by a hydraulic cylinder 21a that connects the front of the roof 9a to the top of the front wall 6 of the luggage compartment 3, and a hydraulic cylinder 21b that connects the rear of the roof 9a to the top of the rear frame 7 of the luggage compartment 3. Opening and closing switches 22 that issue commands to open and close the wing 9 are provided on both the left and right sides of the rear frame 7 of the luggage compartment 3.

The vehicle 1 configured in this manner is equipped with a safety control device for opening and closing the wing 9 of the luggage compartment. Figure 2 shows a block diagram illustrating the general configuration of the safety control device 31 of this embodiment, and the following description will be based on this figure.

The safety control device 31 has an opening/closing switch 22, an opening/closing mechanism 23, an opening/closing control unit 24, and an opening/closing sensor 25 (opening/closing detection unit) on the body side, with the dashed line shown in Figure 2 as the boundary. The safety control device 31 also has an ECU 32 (control unit), a shift operation unit 33, a parking brake 34, a vehicle speed sensor 35 (vehicle speed detection unit), a wing opening/closing information acquisition unit 36, and a body control switch 37 on the vehicle side.

First, we will explain the configuration of the safety control device 31 on the mounting side.

The opening/closing switch 22 is, for example, a push button switch, and is a set of an "open" button and a "close" button, and is installed, for example, on the rear frame 7 as shown in FIG. 1. The opening/closing switch 22 constitutes part of the electric circuit of the opening/closing control unit 24, and for example, by continuing to press the "open" button, the DC electric motor operates the hydraulic pump to generate hydraulic pressure, and the hydraulic cylinders 21a, 21b can continue to open the wing 9. Furthermore, by releasing the press of the "open" button, the opening operation of the wing 9 stops. Regarding the closing operation using the "close" button, the opening/closing control unit 24 controls the opening/closing mechanism 23 in response to pressing the "close" button to close the wing 9.

The opening and closing mechanism 23 includes the hydraulic cylinders 21a, 21b, DC electric motor, and hydraulic pump described above, as well as a battery, an oil tank, valves, and pipes and hoses that connect these.

The opening/closing control unit 24 is an electric circuit having relays and switches, and can drive the DC electric motor and operate various devices of the hydraulic circuit of the opening/closing mechanism 23 described above depending on the state of the opening/closing switch 22. The opening/closing control unit 24 operates only when the body control switch 37 described later is in the on state.

The opening/closing sensor 25 is, for example, a limit switch or a proximity sensor, and is installed, for example, on the wing 9, the front wall 6, the rear frame 7, or the center rail 11, and has the function of detecting the open state of the wing 9. Note that it may detect only the closed state, both the open and closed states, or the opening angle.

Next, the vehicle-side configuration of the safety control device 31 will be described.

The shift operation unit 33 has, for example, a shift lever and is installed near the driver's seat. The shift operation unit 33 allows the driver to select a shift range by changing the position of the shift lever. In this embodiment, the shift range includes a driving power transmission range consisting of a D (drive) range for forward driving and an R (reverse) range for reverse driving, and a driving power non-transmission range consisting of an N (neutral) range in which the transmission gear is in neutral. In other words, the driving power transmission range is a shift range in which the power generated by the engine is transmitted to the wheels and the vehicle 1 can move forward or backward, and the driving power non-transmission range is a shift range in which the power generated by the engine is not transmitted to the wheels. The shift operation unit 33 is electrically connected to the ECU 32 and can transmit shift position information related to the selected shift range to the ECU 32.

The parking brake 34 is, for example, a wheel parking brake, and has a braking function for maintaining the vehicle 1 in a parked state. The operation unit of the parking brake 34 may be a side lever type next to the driver's seat, a foot-operated type, or a switch type.

The vehicle speed sensor 35 has the function of detecting the speed of the vehicle 1.

The wing opening/closing information acquisition unit 36 has the function of acquiring opening/closing information of the wing 9 from the opening/closing sensor 25 on the body side.

The body mounting control switch 37 is a switch for switching the opening/closing control unit 24 on the body mounting side between the on state and the off state, and the opening/closing control unit 24 can be operated by switching the body mounting control switch 37 to the on state. The body mounting control switch 37 is electrically connected to the ECU 32, and can be switched on and off in response to instructions from the ECU 32. The body mounting control switch 37 can also be operated manually, for example, by a switch installed near the driver's seat of the cab 4.

The ECU 32 is a control unit that includes a central processing unit (CPU), a storage device (ROM, RAM, etc.) for storing control programs and control maps, an input/output device, a timer counter, etc. The ECU 32 can obtain information from various devices and other control units mounted on the vehicle 1 via the CAN (Controller Area Network), which is an in-vehicle communication network, and control various devices based on the obtained information.

For example, the ECU 32 of this embodiment receives inputs of shift position information from the shift operation unit 33, parking brake on/off information from the parking brake 34, vehicle speed information from the vehicle speed sensor 35, and wing 9 opening/closing information from the wing opening/closing information acquisition unit 36. On the other hand, the ECU 32 can control a shift lock that prohibits the shift operation of the shift operation unit 33, a parking lock that prohibits the operation of the parking brake 34, and on/off switching of the body control switch. In addition, the ECU 32 may also be capable of controlling switching between driving and stopping of an engine (not shown), shift control of a transmission connected to the engine, and the like.

In this manner, the ECU 32 of this embodiment is a control unit that mainly monitors the running/stopped state of the vehicle 1 and the open/closed state of the wing 9, and can also control the shift operation unit 33, the parking brake 34, and the body control switch 37. Note that, for the sake of convenience in this embodiment, the ECU 32 is described as one control unit, but it may be composed of multiple ECUs, such as an engine ECU that controls the engine and a transmission ECU that controls the transmission.

In addition, in this embodiment, the ECU 32 and the wing opening/closing information acquisition unit 36 are described separately, but this is not limited thereto, and for example, the ECU 32 may be integrated so as to also function as the wing opening/closing information acquisition unit 36.

The ECU 32 of the safety control device 31 of this embodiment can execute a driving prohibition control that does not allow the vehicle 1 to drive while maintaining the key-on state or the engine idling state when the wing 9 is open. In addition, the safety control device 31 can execute an opening prohibition control that does not open the luggage compartment 3 when the power transmission possible range is selected in the shift operation unit 33 or the parking brake 34 is released (off state), i.e., when the vehicle is in a state where it is possible to drive. The driving prohibition control and the opening prohibition control are described in detail below. Note that each control may be implemented individually.

Figure 3 shows a flowchart illustrating a safety control routine for the wing 9 executed by the ECU 32 of the safety control device 31 according to this embodiment, and the following description will be given along with this flowchart. Note that while the ECU 32 is executing this safety control routine, the engine is maintained in an operating state.

First, in step S1, the ECU 32 acquires shift position information from the shift operation unit 33 and determines whether the currently selected shift range is a range in which driving power cannot be transmitted (N range). If the determination result is true (YES), the process proceeds to step S2.

In step S2, the ECU 32 determines whether the parking brake 34 is activated (ON). If the determination result is true (YES), the process proceeds to step S3.

In step S3, the ECU 32 determines whether the vehicle speed detected by the vehicle speed sensor 35 is less than a predetermined vehicle speed. The predetermined vehicle speed is set to a vehicle speed at which it can be determined that the vehicle 1 is stopped. If the result of this determination is true (YES), the process proceeds to step S4. In other words, if all of the results of the determinations in steps S1 to S3 are true (YES), it can be determined that the vehicle 1 is stopped.

In step S4, the ECU 32 turns on the body control switch 37. This enables the body-side opening/closing control unit 24 to operate.

Next, in step S5, the ECU 32 acquires the opening/closing information of the wing 9 detected by the opening/closing sensor 25 via the wing opening/closing information acquisition unit 36, and determines whether the wing 9 is "open." If the determination result is true (YES), i.e., if the wing 9 is in the open state, the process proceeds to step S6.

In step S6, the ECU 32 performs a shift change prohibition control that prohibits the shift operation unit 33 from changing to a driving power transmittable range (specifically, D range, R range). Specifically, the ECU 32 performs the shift change prohibition control by mechanically prohibiting the shift operation unit 33 from selecting a shift range. For example, a lock mechanism is provided on the shift lever of the shift operation unit 33, and the lock mechanism is activated to mechanically prohibit the selection of the shift range. Alternatively, if the shift operation unit 33 is electronically controlled, an electrical lock may be performed to invalidate a signal to switch to a driving power transmittable range (D range, R range).

Next, in step S7, the ECU 32 performs parking brake release prohibition control to prohibit the parking brake 34 from being released. Specifically, the ECU 32 performs parking brake release prohibition control to mechanically prohibit the parking brake 34 from being operated. For example, a lock mechanism is provided in the operation section of the parking brake 34, and the operation of the parking brake 34 is mechanically prohibited by activating the lock mechanism. Alternatively, if the parking brake 34 is electronically controlled, an electrical lock may be performed to invalidate the signal to release the parking brake 34.

Then, in step S8, the ECU 32 determines whether the wing 9 is "closed" using the wing opening/closing information acquisition unit 36. If the determination result is false (No), that is, if the wing 9 is still in the open state, the process returns to step S6, and the shift change prohibition control in step S6 and the parking brake release prohibition control in step S7 are maintained.

On the other hand, if the determination result of step S8 is true (Yes), i.e., if the wing 9 is closed, proceed to step S9.

In step S9, the ECU 32 cancels the shift change prohibition control in step S6 and the parking brake release prohibition control in step S7, enables operation of the shift operation unit 33 and the parking brake 34, and returns to the routine.

The above steps S1 to S9 constitute the driving prohibition control by the ECU 32.

On the other hand, if the shift range is not a range in which driving power cannot be transmitted in step S1, i.e., if the shift range is a range in which driving power can be transmitted (D range, R range), the ECU 32 proceeds to step S10. The ECU 32 also proceeds to step S10 if the parking brake 34 is not in an actuated state in step S2, i.e., if the parking brake 34 is in a released state (off state). Furthermore, the ECU 32 also proceeds to step S10 if the vehicle speed detected by the vehicle speed sensor 35 is not less than a predetermined vehicle speed in step S3, i.e., if the vehicle speed is equal to or greater than the predetermined vehicle speed.

In step S10, the ECU 32 locks the opening/closing switch 22 via the opening/closing control unit 24. This locking of the opening/closing switch 22 is performed, for example, by a mechanical locking mechanism provided in the opening/closing switch 22, or by an electrical lock that invalidates the open signal of the opening/closing switch 22.

Furthermore, in step S11, the ECU 32 turns off the body control switch 37. This disables the operation of the body-side opening/closing control unit 24, and the opening/closing mechanism 23 becomes inoperable.

In step S12, the ECU 32 determines whether the wing opening/closing information acquisition unit 36 has acquired information on the opening of the wing 9 from the opening/closing sensor 25 on the body side. If the result of the determination is false (No), the routine is returned. On the other hand, if the result of the determination is true (Yes), the process proceeds to step S13.

In step S13, the ECU 32 detects an open state from the open/close sensor 25 on the body side while the vehicle 1 is in a drivable state, the open/close switch 22 is locked, and the body control switch 37 is turned off. Since there is a possibility that the open/close sensor 25 is making an erroneous detection, the ECU 32 issues an alert to the driver and returns the routine.

The above steps S1 to S3 and S10 to S13 are the release prohibition control by the ECU 32.

As described above, when the ECU 32 of the safety control device 31 according to this embodiment acquires information on the opening of the luggage compartment 3 from the wing opening/closing information acquisition unit 36, which acquires information on the opening/closing of the luggage compartment 3 of the vehicle 1, it performs a driving prohibition control, which prohibits the shift operation unit 33 from changing the shift range to a driving power transmission range (D range, R range) and a parking brake release prohibition control, which prohibits the release of braking by the parking brake 34.

In other words, when the luggage compartment 3 is open, the shift operation unit 33 and the parking brake 34 are locked to prevent the vehicle 1 from being driven. This makes it possible to prevent the vehicle from being driven with the luggage compartment 3 open. Although the ECU 32 locks the shift operation unit 33 and the parking brake 34, it does not stop the engine, but keeps it in an idling state even when the vehicle is stopped. Therefore, various auxiliary devices such as the air conditioner that use engine power can continue to operate.

In addition, in the shift change prohibition control, the ECU 32 mechanically prohibits the selection of a shift range by the shift operation unit 33. Specifically, the selection from a range in which driving power cannot be transmitted to a range in which driving power can be transmitted is mechanically prohibited. By mechanically prohibiting the selection of a shift range by the shift operation unit 33 in this manner, it is possible to reliably prevent a change to a range in which driving power can be transmitted, and to easily allow the driver to recognize that a shift operation is prohibited.

In addition, in the shift change prohibition control, the ECU 32 may electrically prohibit the shift change by invalidating a signal indicating a shift range corresponding to the shift range selection operation by the shift operation unit 33, thereby making it possible to easily prevent a change to the shift range.

Furthermore, the ECU 32 performs an opening prohibition control that prohibits the opening of the luggage compartment 3 by the open/close switch 22 when at least one of the following conditions is met: when the driving power transmission range (D range, R range) is selected by the shift operation unit 33, and when the parking brake 34 is in a released state. In other words, when the driving power transmission range is selected or the parking brake 34 is released, the vehicle 1 is in a driveable state, so by prohibiting the opening of the luggage compartment 3 in such a state, it is possible to prevent the vehicle from driving with the luggage compartment 3 open.

Furthermore, the ECU 32 also performs the open prohibition control when the vehicle speed detected by the vehicle speed sensor 35 is equal to or greater than a predetermined vehicle speed. In this way, by determining the traveling state of the vehicle 1 from the vehicle speed as well, it is possible to more accurately detect the traveling of the vehicle and more reliably prevent the vehicle from traveling with the luggage compartment 3 open.

In addition, when ECU 32 acquires open information from the open/close sensor 25 by the wing open/close information acquisition unit 36 while the open prohibition control is being executed, ECU 32 invalidates the acquired open information. The open/close sensor 25 may make a false detection due to vibrations caused by the vehicle traveling. Therefore, when the open information of the cargo compartment 3 is acquired despite the execution of the open prohibition control of the cargo compartment 3, the open information is judged to be a false detection and invalidated, thereby preventing malfunction of other devices based on the open information due to a false detection, and more reliably preventing the vehicle from traveling with the cargo compartment 3 open.

In addition, in the above embodiment, the driving power transmission impossible range includes the N range, so that in a vehicle including the N range, it is possible to prevent the vehicle from traveling with the luggage compartment 3 open. Also, in a vehicle 1 having a wing 9 that opens and closes the luggage compartment 3, it is possible to prevent the vehicle from traveling with the wing 9 open.

This concludes the description of the embodiment of the present invention, but the aspects of the present invention are not limited to this embodiment.

In the above embodiment, the driving power transmittable range is described as D (drive) range, R (reverse) range, and the driving power non-transmittable range is described as N (neutral) range, but the driving power transmittable range and the driving power non-transmittable range are not limited to these. For example, the driving power non-transmittable range may include P (parking) range. This makes it possible to prevent the vehicle from traveling with the luggage compartment 3 open in a vehicle in which the driving power non-transmittable range includes the P range.

The shift operation unit is not limited to a floor shift, column shift, instrument shift, or other shift lever, but may also be a paddle shift, button type, or dial type.

In addition, in the above embodiment, the opening and closing mechanism 23 of the wing 9 is hydraulic cylinders 21a, 21b via an electric motor, but the wing opening and closing mechanism is not limited to this, and may be entirely electric actuators or actuators using air pressure. Also, the wing may be manually opened and closed.

In the above embodiment, the ECU 32 performs both the shift change prohibition control and the parking brake release prohibition control as the driving prohibition control when the opening/closing information of the wing 9 is "open." However, the ECU 32 may be configured to perform only one of the controls when the opening/closing information of the wing is "open."

The safety control device 31 in the above embodiment has been described as being mounted on a wing-type truck with the sides of the luggage compartment 3 that open and close, but the type of vehicle is not limited to this. For example, the device can also be applied to the rear door 8 of the luggage compartment 3 in this embodiment, or the luggage compartment (trunk room) of a passenger car.

In addition, although the vehicle in the above embodiment is an engine-driven vehicle, the drive source of the vehicle is not limited to an engine, but may be a hybrid vehicle using an engine and a motor as a drive source, or an electric vehicle or fuel cell vehicle using only a motor as a drive source. In addition, the transmission of the vehicle may be an automatic transmission, or may be a manual transmission, AMT (automatic manual transmission), CVT (continuously variable transmission), or the type of transmission is not limited.

In addition, vehicles such as electric vehicles and fuel cell vehicles may not have a transmission. In this case, the shift operation unit and shift range may refer to parts that move the vehicle forward, backward, or keep it stopped.

In addition, in the above embodiment, the opening/closing switch 22 that instructs the luggage compartment 3 to be opened or closed is provided on the body side, but it may be provided on the vehicle side. For example, the body control switch 37 may also function as the opening/closing switch that instructs the luggage compartment to be opened or closed.

In addition, when the shift operation unit is in a driving power transmission range or the parking brake is in a released state (off state) and the cargo compartment is opened, the ECU may automatically switch the shift operation unit to a driving power transmission non-transmittable range and perform shift change prohibition control, or automatically switch the parking brake to a braking state (on state) and perform parking brake release prohibition control.
