Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a remote control device for a vehicle that performs communication between a remote control device carried by a user and an in-vehicle device mounted on a vehicle, and permits start of an engine when an ID is collated. In particular, the present invention relates to a technique for reducing battery consumption of a remote controller.
[0002]
[Prior art]
In a passive keyless device as a vehicle remote control device that has been used conventionally, for example, as disclosed in Japanese Patent Laid-Open No. 2002-53010 (Patent Document 1), it is mounted on a remote controller and a vehicle carried by a user. When the communication is performed with the vehicle-mounted device and the ID is verified, the door lock of the vehicle is unlocked and the engine is allowed to start. According to such a configuration, the door lock of the vehicle is unlocked only by the user having the remote control unit approaching the vehicle, so that convenience is good and only an authorized user carrying the remote control unit has the engine. Since it can be started, it is rich in anti-theft.
[0003]
In such a passive keyless device, when the ID is verified by communication between the remote controller and the in-vehicle device, the engine is allowed to start. For example, the ID is verified once and the engine is started. If the remote controller is taken out of the vehicle for some reason, and the driver starts driving the vehicle without knowing this, the engine will be started after it arrives at the destination and stops the engine. It becomes impossible to do.
[0004]
Therefore, in order to solve such a problem, when the remote controller is taken out of the vehicle, this is notified to the user by an alarm.
[0005]
FIG. 4 is a flowchart showing a conventional procedure for outputting a remote controller take-out alarm. First, it is determined whether or not there is an engine start request (step ST101). If there is an engine start request, communication with the remote control device is performed using an antenna in the vehicle compartment (step ST102). When the ID is collated between the in-vehicle device and the remote control device by communication (step ST103), the engine is started (step ST104).
[0006]
Next, it is determined whether or not the vehicle door is open (step ST105). If the vehicle door is not open (NO in step ST105), a 30-second timer provided in the vehicle-mounted device is started (step ST106), and every 30 seconds have elapsed. In step ST107, communication with the remote control device is performed using the antenna in the vehicle interior (step ST108).
[0007]
If communication is not possible (NO in step ST109), it is determined that the remote controller has been taken out of the vehicle, and an alarm is issued by turning on a warning lamp (step ST110). If communication is possible (YES in step ST109), no alarm is output, and if an alarm has already been output, this is stopped (step ST112).
[0008]
Thereafter, when the shift lever is set to a position other than parking and neutral, or when the vehicle is in a take-out end mode (YES in step ST111), the process ends.
[0009]
On the other hand, if the door is open (YES in step ST105), a 5-second timer of the in-vehicle device is started (step ST113) and every 5 seconds (step ST114), the remote control device is connected with the antenna in the vehicle interior. Communication is performed between them (step ST115).
[0010]
If communication is not possible (NO in step ST116), it is determined that the remote controller has been taken out of the vehicle, and an alarm is issued (step ST117). If communication is possible (YES in step ST116), no alarm is output, and if an alarm has already been output, this is stopped (step ST118). Thereafter, similarly to the above, when the take-out end mode is set (NO in step ST111), the process is ended.
[0011]
Here, in the conventional passive keyless device, when the vehicle is stopped, or when the shift lever is set to the take-out mode such as the parking or neutral position, In order to notify the user immediately when there is a take-out, it is necessary to continuously perform communication between the in-vehicle device and the remote control device.
[0012]
That is, as shown in steps ST108 and ST115 of FIG. 4, in-vehicle communication is performed every 30 seconds or every 5 seconds until the take-out end mode is set.
[0013]
For this reason, if you have been in the vehicle for a long time with the engine started, for example, if you are waiting in the vehicle while waiting for the parking lot during pick-up or warming up at the ski resort, Thus, communication between the in-vehicle device and the remote control device is performed, and the battery mounted on the remote control device is greatly consumed.
[0014]

[0028]
FIG. 2 is an explanatory view showing a mounting state of the window sensor mounted on the vehicle. As shown in the figure, the window sensor is mounted in the vicinity of the upper portion of the window frame of the door glass 31. When 31 reaches the uppermost end and is fully closed, this is detected and output to the passive keyless controller 1 shown in FIG.
[0029]
Next, the operation of the vehicle remote control device 100 according to this embodiment will be described with reference to the flowchart shown in FIG.
[0030]
First, it is determined whether there is an engine start request by the push switch 10 (step ST1). If there is an engine start request (YES in step ST1), a communication signal is output from the indoor antennas 14 and 15 (step ST2), and if communication with the remote controller 21 is possible (step ST2) The engine is started (step ST4).
[0031]
Next, it is determined whether or not the door is open based on the detection signals of the request switches 7 to 9 (step ST5). If the door is open (YES in step ST5), the vehicle every 5 seconds. The indoor communication timer is started (step ST8). Every time 5 seconds elapse (step ST9), a communication signal is output from the indoor antennas 14 and 15 to communicate with the remote controller 21 (step ST10).
[0032]
If in-vehicle communication is possible (YES in step ST11), no alarm is output. If an alarm is output, this is stopped (step ST13), and the process returns to step ST5.
[0033]
If communication within the vehicle is not possible (NO in step ST11), it is determined that the remote controller 21 has been taken outside, and an alarm is issued by turning on a warning lamp (step ST12). Notify the user that it was taken outside.
[0034]
Thereafter, it is determined whether or not it is in the takeout end mode, that is, whether or not the takeout enable mode is ended (YES in step ST7). Here, the take-out possible mode is a mode for setting whether or not the remote controller 21 can be taken out of the vehicle. For example, when the shift lever is set to the parking and neutral positions, Is stopped or traveling at a speed of less than 5 km / h. Then, for example, when the take-out-possible mode is ended by starting the vehicle or the like (step ST7), the remote control device 21 exists in the passenger compartment and the remote control device 21 is not taken out to the outside. It judges that it is a thing and complete | finishes a process.
[0035]
On the other hand, if it is determined in step ST5 that the door is closed (NO in step ST5), it is determined whether or not each window is open (step ST6). In this case, the user can set in advance which window is used to determine the open / closed state, and can also target all windows. For example, even when the rear seat window is open, if the remote controller 21 is not clearly taken out from the opened window, the driver seat and the passenger seat are set as preset windows. In this case, if at least one of the driver seat and passenger seat windows is not fully closed, it is determined that the window is open (NO in step ST6). As another example, when all windows are targeted, if all the windows mounted on the vehicle are not fully closed, it is determined that the windows are open.
[0036]
Thereafter, similarly to the above-described procedure, the processes from step ST8 to step S13 are performed.
[0037]
If the window is closed (NO in step ST6), the communication between the passive keyless controller 1 and the remote controller 21 is not performed, and the process proceeds to the determination of whether the mode is the takeout end mode (step ST7). That is, when all the windows set by the user are closed, the remote control device 21 cannot be taken out of the vehicle interior to the outside. Therefore, by stopping communication with the remote control device 21, the remote control device 21 is stopped. The power consumption of the battery which 21 has can be reduced.
[0038]
As described above, in the vehicle remote control device 100 according to the present embodiment, the passive keyless controller 1 and the remote controller when all the windows set in advance by the user among the windows mounted on the vehicle are fully closed. Since communication with the machine 21 is controlled to be stopped, unnecessary communication can be omitted when the vehicle is stopped for a long time with the engine started. Battery consumption can be reduced. Thereby, the lifetime of a battery can be lengthened and frequent battery replacement can be avoided.
[0039]
Further, by stopping unnecessary communication, it is possible to prevent the influence of noise on other devices such as a radio.
[0040]
As mentioned above, although the vehicle remote control apparatus of this invention was demonstrated based on embodiment of illustration, this invention is not limited to this, The structure of each part is set to the thing of the arbitrary structures which have the same function. Can be replaced.
[0041]
For example, in the above-described embodiment, the example in which the communication between the passive keyless controller 1 and the remote controller 21 is stopped when the window is fully closed has been described. However, the communication time interval is increased. Thus, it is possible to obtain a power saving effect similar to that when the communication is substantially stopped.
[0042]
【The invention's effect】
As described above, in the vehicle remote control device according to the present invention, when all the predetermined windows are fully closed, the communication between the in-vehicle device and the remote control device is stopped or the communication interval is lengthened. For example, when waiting for a parking lot at the time of pick-up or when warming up at a ski resort, when the engine is started and the vehicle is stopped for a long time, the remote control The battery consumption of the machine can be suppressed, and the generation of noise can be prevented.
