  The present invention relates to a vehicular alarm device that issues alarm information based on a vehicle alarm condition, and can notify alarm information at an optimal timing based on a past operation state of the vehicle.

  Hereinafter, an embodiment in which a vehicular alarm device of the present invention is applied to a vehicular instrument will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the vehicle meter includes a control unit 1, a storage unit 2, a display unit 3, and a notification unit 4.

  For example, a microcomputer can be applied to the control means 1 and connected to various switches and sensors mounted on the vehicle via wiring and other control devices, and various vehicle information is input from the sensor and the like. Then, a control signal for controlling the display means 3 and the notification means 4 is generated and output. Further, the control means 1 stores a CPU for performing arithmetic processing based on various vehicle information, a readable / rewritable RAM for temporarily storing arithmetic processing results in the CPU, a control program and control data. A storage unit including a ROM, and an input / output interface connected via a bus for exchanging various vehicle information, control signals, clock signals, latch signals, and the like are provided.

  For example, an external storage unit such as an EEPROM or a flash memory can be applied to the storage unit 2, and even when there is no power supply to the control unit 1, a part of data can be stored. In this case, the storage means 2 stores information such as a set time, which will be described later, when the vehicle ignition switch or accessory power supply is operated from on to off. Note that the storage unit 2 may not be a non-volatile memory, and can also be used as, for example, the storage unit (RAM) of the control unit 1.

  The display means 3 is a display based on a control signal from the control means 1 in a vehicle instrument provided in the instrument panel. For example, a liquid crystal display panel or a driver for driving the liquid crystal display panel can be applied. . In this case, the display means 3 displays the outside temperature of the vehicle, the fuel consumption, the vehicle speed, the engine speed, the accumulated travel distance, etc. with gauges or numerical values. As the display means 3, a so-called analog display that displays with a pointer that rotates according to a control signal and an index such as a scale or a numerical value that is a target of the pointer can be used. Moreover, the display means 3 can also perform the display which shows the kind etc. of alarm information alert | reported by the alerting | reporting means 4 using a liquid crystal display panel.

  In this case, the notification means 4 can apply a speaker provided in the vehicular instrument, emits a notification sound or a sound based on a control signal from the control means 1 and notifies the driver. In addition, the alerting | reporting means 4 is not provided in the said vehicle meter, but can also serve as the speaker for audio equipment provided in the door of a vehicle, etc.

  Next, a processing procedure related to the control of the notification unit 4 by the control unit 1 will be described with reference to FIGS. As an example, an alarm regarding forgetting to remove a key will be described.

  The control means 1 inputs vehicle information from various switches and sensors, and performs an alarm condition determination process (determination process) for determining whether or not the vehicle information satisfies an alarm condition (step S1). In this case, based on vehicle information from the sensor provided in the key cylinder and the door switch on the driver's seat, the alarm condition is set when the key is inserted into the key cylinder and the driver's seat side door is opened. It is determined that the condition is satisfied, and the following processing is performed to warn of forgetting to remove the key.

  When it is determined that the alarm condition is satisfied in the alarm condition determination process of step S1, the control means 1 determines whether or not the alarm condition is released (step S2). In this case, it is determined that the alarm condition is released when the key is removed from the key cylinder or the driver's seat side door is closed. The control means 1 performs a control process so that, for example, a notification sound such as “pea” is emitted from the notification means 2 when it is determined in the alarm condition determination process in step S1 that the alarm condition is satisfied. Yes.

  In addition, when it is determined in step S2 that the alarm condition has not been released, the control unit 1 determines the elapsed time after the alarm condition is determined to be satisfied by the alarm condition determination process in step S1. Is measured, and an elapsed time determination process for comparing this elapsed time with a set time (delay time) determined by a separate process is performed (step S3). The control unit 1 can obtain the comparison target of the elapsed time by reading the set time stored in the storage unit 2.

  The control means 1 compares the elapsed time with the set time by the elapsed time determination process in step S3, and is equal to or longer than the set time after it is determined that the alarm condition is satisfied by the alarm condition determination process in step S1. If it has elapsed, a notification process is performed to output a control signal that prompts the alarm information to be emitted by voice to the notification means 4 (step S4). In this case, the control means 1 controls the notification means 4 so that a sound indicating the type of alarm such as “key is inserted” is emitted.

  Moreover, the control means 1 performs a set time update process (setting process), when it determines with the said alarm conditions having been cancelled | released in the process of step S2 (step S5). When it is determined that the alarm condition is released, the control unit 1 performs a control process for stopping a notification sound or a sound generated by the notification unit 1 by another process.

  As shown in FIG. 3, in the set time update process, the control unit 1 determines from the determination that the alarm condition is satisfied by the alarm condition determination process in step S1 until it is determined that the alarm condition is released. Time is measured as elapsed time (measurement process), and this elapsed time is compared with the set time (step S51).

  When it is determined by the determination in step S51 that the elapsed time is shorter than the set time, that is, the control unit 1 detects the alarm condition by, for example, removing the key before the alarm unit 4 issues a voice alarm. When is canceled, the current set time stored in the storage means 2 is read, and a time longer than the set time is updated as a new set time and stored in the storage means 2 (step S52). In this case, the control unit 1 updates the set time by extending it by 1 second. Therefore, the vehicular alarm device can determine that the driver is accustomed to the vehicle operation and can delay the alarm timing by the next voice.

  In addition, the control unit 1 determines that the alarm condition is met by determining that the elapsed time is equal to or longer than the set time by the determination in step S51, that is, after the alarm unit 4 issues a voice alarm, the driver removes the key. When is canceled, the current set time stored in the storage means 2 is read, and a time shorter than the set time is updated as a new set time and stored in the storage means 2 (step S52). In this case, the control unit 1 updates the set time by shortening it by 2 seconds. Therefore, the vehicular alarm device can determine that the driver is not used to operating the vehicle, and can advance the alarm timing by the next voice.

  It should be noted that the set time set here can also be used when other alarms such as forgetting to turn off lights or a seat belt reminder are given. When applied by a seat belt reminder, the control means 1 warns when the vehicle starts or the vehicle travels without wearing the seat belt, based on the seat belt attaching / detaching sensor and the ignition switch or the vehicle speed sensor. As a condition, it is possible to perform control similar to the above-described processing procedure so as to issue alarm information by voice for prompting the notification means 4 to release the alarm condition such as “please wear a seat belt”.

  By repeating the above process, it is determined that the alarm condition is satisfied in the alarm condition determination process, and the following sound is emitted, and the following is performed according to the elapsed time until the alarm condition is canceled by the driver. It is possible to change the timing until a warning is given by voice, and when the driver is accustomed to operating the vehicle, the warning information is often notified and the vehicle can be operated comfortably without feeling bothered. In addition, when the driver is not familiar with the vehicle operation, an audio guide indicating the type of alarm or the canceling method can be notified at an early timing.

  Such a vehicle warning device is a vehicle warning device comprising a notification means 4 for issuing warning information and a control means 1 for controlling the notification means 4 based on the vehicle information. An alarm condition determination process (step S1) for determining whether or not the vehicle information satisfies an alarm condition; a measurement process for measuring an elapsed time from when the alarm condition is satisfied until the alarm condition is canceled; The alarm condition is satisfied by the set time update process (step S5) for setting the set time from when the alarm condition is satisfied until the alarm information is issued based on the elapsed time, and the alarm condition determination process S1. A notification process (step S4) for controlling the notification means 4 to issue alarm information when the set time has not elapsed and the alarm condition is not canceled. .

  Therefore, it is possible to determine whether or not the driver is accustomed to the vehicle operation based on the past vehicle operation situation, and to issue the alarm information at the optimal timing, and the alarm information with less necessity delays the notification, Alternatively, it is possible to reduce annoyance to the driver by notifying alarm information that is highly necessary early.

  Further, in the alarm condition setting process (step S1), the control unit 1 calculates a new set time by comparing the set time set in the past with the elapsed time measured by the measurement process. Thus, when the elapsed time is smaller than the set time set in the past, the new set time is set to be longer.

  Therefore, the vehicle alarm device can determine that the driver is accustomed to the vehicle operation, can delay the alarm timing by the next voice, and can reduce the chance of hearing the alarm that the driver understands, Annoyance can be reduced.

  Further, the control means 1 calculates a new set time by comparing the set time set in the past with the elapsed time measured by the measurement process in the alarm condition setting process (step S1). When the elapsed time is longer than the set time set in the past, the new set time is set to be smaller.

  Therefore, the vehicular alarm device can determine that the driver is not familiar with vehicle operation, can advance the alarm timing by the next voice, and can quickly provide alarm information to the driver.

  Moreover, the alerting | reporting means 4 consists of a speaker, and can alert | report alarm information at the optimal timing about the vehicle information in an audio | voice guidance by emitting alert information with an audio | voice, and can reduce annoyance.

  In addition, the control means 1 can promptly provide voice guidance to a driver who is not used to operating the vehicle by controlling the notifying means 4 so as to issue alarm information that prompts cancellation of the alarm condition. Therefore, it becomes a comfortable vehicle alarm device.

  In addition, the control means 1 controls the notification means 4 so as to emit a notification sound different from the voice until the warning information is issued by the voice after the warning condition is satisfied, thereby giving the driver a warning. On the other hand, the alarm state can be quickly detected.

  Although the vehicular alarm device of the present invention has been described as an example in the configuration of the above-described embodiment, the present invention is not limited to this, and the gist of the present invention is also achieved in other configurations. It goes without saying that various improvements and design changes can be made without departing from the scope.
