DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows the configuration of one embodiment.
The controller 1 is composed of a microcomputer and its peripheral components, and performs anti-theft processing. A remote control entry system (hereinafter referred to as a remote control entry device) 2, an intrusion sensor 3, a tilt sensor 4, and a vehicle speed sensor 5 are connected to the controller 1.
[0010]
The remote control entry device 2 receives a password, door lock / unlock command and trunk lid opening command transmitted from a remote control key (not shown) (hereinafter referred to as a remote control key) via the antenna 2a, and the password is registered in advance. If the number matches, the door lock / unlock command and the trunk lid opening command are sent to the controller 1.
[0011]
The intrusion sensor 3 installs ultrasonic transmitters and receivers in, for example, the left and right center pillars in the vehicle interior, detects a moving object in the vehicle interior, and sends an alarm signal to the controller 1. The tilt sensor 4 sends an alarm signal to the controller 1 when the vehicle tilts more than a predetermined angle. The vehicle speed sensor 5 generates a pulse signal for each predetermined travel distance of the vehicle and outputs the pulse signal to the controller 1. The controller 1 detects the vehicle speed based on this pulse signal.
[0012]
The controller 1 is also connected with turn signal lamps L1 to L4, a horn 6, and various switches. Various switches include a switch ACC that closes when the ignition key is in the ACC, ON, or START position, a switch ON that closes when the ignition key is in the ON or START position, a driver's seat door, and a passenger's seat door , Door switches DO1 to DO4 that are closed when the rear left and right doors are open, and door lock switches DL1 that detect the lock / unlock state of the door lock actuators of the driver's door, the passenger's door, and the rear left and right doors. DL4, trunk lid opener switch TO, switch TUL that closes when the trunk lid is unlocked, switch FO that closes when the hood is open, and closed when the shift lever is in the parking position (P position) A parking switch SP is included. BAT is a battery power source.
[0013]
FIG. 2 is a flowchart showing a process for setting theft prevention regardless of the position of the ignition key.
Here, the anti-theft set means a so-called deadlock that locks the door so that it is not released and activates an intrusion sensor and a tilt sensor to perform the necessary processing to prevent theft of the vehicle. In this state, if an unauthorized entry into the passenger compartment or a tilt of the vehicle is detected, a necessary alarm is given by blinking a lamp or blowing a horn. The anti-theft reset is to release such a theft alert state.
[0014]
The controller 1 executes this process at predetermined time intervals. In step 21, it is confirmed that all the lids (doors, trunks, hoods) of the vehicle are closed by the switches DO1 to DO4, TUL, and FO. If all the lids are closed, the process proceeds to step 22. In step 22, it is confirmed that all the doors of the vehicle are locked by the switches DL1 to DL4, and if all the doors are in the locked state, the process proceeds to step 23. In step 23, it is confirmed whether or not a door lock command is received from the remote control entry device 2. If the door lock command is received, the process proceeds to step 25. Otherwise, the process proceeds to step 24. If the door lock command has not been received from the remote control entry device 2, it is checked in step 24 whether the ignition key switch ACC is on. If the switch ACC is on, the process returns to step 21 and the switch ACC is off. That is, if the ignition key is in the OFF position, the process proceeds to step 25.
[0015]
In a state where all the lids of the vehicle are closed and all the doors are locked, if a door lock command is received from the remote control entry device 2, the vehicle is set to be burglar-proof in step 25 and enters a theft monitoring state. In step 26, the turn signal lamps L1 to L4 are blinked for a predetermined time to notify the completion of the anti-theft set. In addition, you may make it notify completion of anti-theft set by blinking a headlamp or sounding the horn 6. FIG.
In this way, when all doors are closed and all doors are locked, when a door lock command is received from the remote control entry device 2, the anti-theft setting is performed regardless of the position of the ignition key. By operating the engine and driving the air conditioner, it becomes possible to air-condition the interior of the vehicle in advance before the operation of the vehicle.
[0016]
In step 27 after the anti-theft setting, the intrusion sensor 3 is operated for a predetermined time, for example, 30 seconds, and it is detected whether or not there are people or animals in the vehicle interior. If the intrusion sensor 3 detects a moving object within a predetermined time immediately after the anti-theft set, it is determined that there are children, animals, etc. in the passenger compartment, and intrusion detection by the intrusion sensor 3 is stopped in step 28.
[0017]
In the above-described embodiment, in the state where all the lids are closed and all the doors are locked, when the door lock command is received from the remote control entry device, the anti-theft setting is performed regardless of the position of the ignition key. When the anti-theft set is made in such a process, the detection by the intrusion sensor 3 and the inclination sensor 4 may be stopped.
[0018]
FIG. 3 is a flowchart showing a modification of the anti-theft setting process regardless of the position of the ignition key. Note that steps that perform the same processing as the processing shown in FIG. 2 are given the same step numbers, and the differences will be mainly described.
In the embodiment shown in FIG. 2, in the state where all the lids are closed and all the doors are locked, when the door lock command is received from the remote control entry device, the anti-theft setting is performed regardless of the position of the ignition key. In this modification, in the state where all the lids are closed and all the doors are locked, if a door lock command is received from the remote control entry device, the process proceeds to step 23A, and whether the shift lever is in the P position by the switch SP. Check if. If it is not in the P position, the process proceeds to step 24 to check whether the ignition key switch ACC is on. When the shift lever is not in the P position and the switch ACC is on, it is determined that the vehicle is in a travelable state and the anti-theft setting is not performed. On the other hand, if it is in the P position, the process proceeds to step 25 to perform the anti-theft setting. Further, in step 26A after the anti-theft setting, the shift lever is locked at the P position by a shift lock mechanism (not shown).
[0019]
FIG. 4 is a flowchart showing an anti-theft reset process when the ignition key is at the ON position and the anti-theft set.
The controller 1 executes this process at predetermined time intervals. In step 41, it is confirmed whether the ignition key switch ON is opened and the ignition key is returned to the OFF position. When the ignition key is returned to the OFF position, it is determined that the occupant gets out of the vehicle, and the routine proceeds to step 49 to reset the anti-theft. If the ignition key remains set to the ON position, the process proceeds to step 42, and whether or not any of the doors is unlocked by the ignition key switch ON and the door lock switches DL1 to DL4 when the ignition key is in the ON position. Confirm. In this case, it is determined that the occupant gets out of the vehicle, and the routine proceeds to step 49 to reset the antitheft.
[0020]
In step 42, when the ignition key is in the ON position and the door is unlocked, it is determined that the occupant is willing to get off the vehicle and the anti-theft is reset. When the unlocking operation is performed, it may be determined that there is an occupant in the passenger compartment and that the occupant has an intention to get off the vehicle and reset the burglar.
[0021]
In step 43, the vehicle speed sensor 5 confirms whether or not the vehicle speed is equal to or higher than a predetermined value K. If the vehicle speed is higher than or equal to the predetermined value K, the process proceeds to step 49 to perform an anti-theft reset. In step 44, it is confirmed by the switch SP whether or not the shift lever is at the P position. Since the ignition key is in the ON position, if the shift lever is not in the P position, the vehicle is in a state where it can travel, and the routine proceeds to step 49 where the antitheft reset is performed.
[0022]
Basically, the vehicle runnable state can be determined based on the vehicle speed or shift lever position.For example, if the vehicle speed or shift lever position detection device is faulty, the vehicle runnable state cannot be determined, and the anti-theft set state. It is possible to travel on the road, which is not preferable. Therefore, in this embodiment, when both the vehicle speed and the shift lever position are satisfied, it is determined that the vehicle is not in a travelable state, and traveling in the anti-theft set state is reliably prevented.
[0023]
The antitheft reset conditions in steps 45 to 48 are basically the same as those of the conventional antitheft device. In step 45, when the trunk lid is opened with the key, the routine proceeds to step 49, where the anti-theft reset is performed. Here, the determination of the trunk opening with the key is made, for example, when the trunk lid opener switch TO is not operated and the trunk lid unlocking switch TUL detects the opening of the trunk lid, it is determined that the trunk lid is opened with the key. .
[0024]
If any of the doors is unlocked by the key at step 46, the routine proceeds to step 49, where the anti-theft reset is performed. Here, the determination of the door unlocking by the key is performed, for example, when any door unlock is detected by the door lock switches DL1 to DL4 without the operation of the central door lock switch or the door lock knob. Judged locked. When the door is unlocked by the remote control entry device 2 at step 47, the routine proceeds to step 49, where the anti-theft reset is performed. Further, at step 49, when the ignition key switch ACC is switched from OFF to ON, it is determined that the occupant has a willingness to travel, and the routine proceeds to step 49, where the anti-theft reset is performed.
[0025]
If the shift lever is locked at the P position during the anti-theft setting, the shift lever P is unlocked by a shift lock mechanism (not shown) in step 50 after the anti-theft reset.
[0026]
FIG. 5 is a flowchart showing a modification of the anti-theft reset process when the ignition key is in the ON position and anti-theft is set. Note that steps that perform the same processing as the processing shown in FIG.
In step 42A, it is confirmed whether or not the shift lever is in the P position. If it is not in the P position, an antitheft reset is performed, and if it is in the P position, the process proceeds to step 42B. In step 42B, it is confirmed whether or not the vehicle speed is greater than or equal to a predetermined value K. If the vehicle speed is greater than or equal to the predetermined value K, the process proceeds to step 42C. The fact that the vehicle speed is equal to or higher than the predetermined value K even when the shift lever is at the P position may indicate a failure of the P position detection switch SP of the shift lever. Therefore, a failure of the parking switch SP is alarmed at step 42C.
[0027]
Thus, by confirming both conditions of the vehicle speed and the shift lever position, traveling in the anti-theft set state can be surely prevented, and a failure of the P position detection switch SP can also be detected.
[0028]
In the configuration of the above embodiment, the door switches DO1 to DO4, the trunk lid unlock switch TUL, and the hood switch FO are lid closing detection means, the door lock switches DL1 to DL4 are door lock detection means, and the remote control entry system 2 Is the remote control means, the controller 1 is the control means, the parking switch SP is the P position detection means, the intrusion sensor 3 is the animal detection means, the shift lock mechanism (not shown) is the shift lock means, and the vehicle speed sensor 5 is the vehicle speed. Concentration door switches (not shown) constitute detection doors and central door unlocking means.
Vehicle lids include fuel lids, windows, sunroofs, etc., in addition to doors, hoods, and trunk lids.
