[Industrial application field]

INDUSTRIAL APPLICABILITY The present invention reliably locks the entire vehicle by interlocking a plurality of doors in the vehicle with the doors that have been locked so that it can be seen that all the doors have been closed. The present invention relates to a vehicle automatic lock control device. [Prior Art] Conventionally, in order to lock the entire vehicle, a power switch of a drive system, a steering wheel, and the like are locked, and doors are locked to prevent entry into the vehicle. Normally, the entire vehicle is locked by locking all the doors, and the vehicle is not considered to be locked unless all the doors are locked. Conventionally, in order to improve the integrity of this locking, one of the main doors, for example, the door on the driver's side is locked, and the other doors are locked accordingly. In order to interlock the locking of each door, an electric actuator is linked to the locking mechanism of each door, and they are electrically interlocked with each other (see JP-B-58-25090). In addition, the locking mechanism of each door in an automobile prioritizes the unlocking operation from the inside of the vehicle in order to ensure safety, and the unlocking operation from inside the vehicle is always effective even when the entire vehicle is in the locked state. It is supposed to be. For unlocking operation for each door when the entire vehicle is in the locked state, the unlocking knob connected to the locking mechanism for each door
This is performed by operating to the unlocking side, and the locking / unlocking knob automatically moves to the locking position when the driver side door is locked and the entire vehicle is ready to be locked. However, the locking / unlocking knob can be moved to the unlocking position by manual operation. The automatic operation of the locking / unlocking knob is performed by activating an electric actuator connected to the locking / unlocking mechanism of each door.The timing of the locking operation of this electric actuator is when the vehicle is ready to be locked. At that time, regardless of whether the doors are open or closed, all the electric actuators of the doors operate in the locking direction at the same time. After that, the doors that have been opened are locked so that they cannot be opened from the outside when they are closed, and the doors that are in the closed state are naturally locked as they are, and when all the doors are closed, the car is locked. Complete. In the automobile, all the doors are closed and all the doors are locked, so that the entire vehicle is locked. However, in the case where the door of the driver's side is locked and the lock of the entire vehicle is interlocked, if the opening and closing order of each door and the operation of the locking and unlocking knob are mistaken, even if the door on the driver's side is locked, Therefore, the locking of the entire vehicle is not substantially completed, resulting in a forgotten locking condition in which one of the other doors remains openable. For example, if the door on the driver's seat side is locked while the passenger is left in the rear seat, then the passenger dismounts from the unlocked door, and if the door is closed, the passenger is automatically locked. However, if the other door was closed when the driver's door was locked and the door had already been locked automatically, the passenger unlocked the door by operating the knob from the inside and disembarked. Close the door. At this time, if you close the door without returning the knob to the locked position,
Only the door is unlocked, and although the door on the driver's side is locked, the vehicle is not locked yet and all the doors are closed. In order to solve the above-mentioned problem, the locking side operation of the knob by the electric actuator may be performed after a required time has elapsed since all the doors were closed. [Problems to be solved by the invention] However, after a lapse of a required time after all the conventional doors are closed,
When the electric lock operation of the knob is performed, once all the doors are closed and the required time is being measured, the doors are opened again and the doors are closed or when the doors are open. Assuming a case where other doors are opened and closed, the required time must be set to a very long time, and the set time zone is unwarranted because the vehicle is not locked. Furthermore, if the knob is electrically operated on the locked side after the required time has elapsed while one of the doors is open, an unlocked door will occur, and in order to prevent this, the door that was closed last after the required time has passed, If the electric lock operation of the knob is directly interlocked, the door will not open immediately after it is closed, which causes inconvenience such as taking out things left behind. [Means for Solving Problems] The present invention is an automatic locking / unlocking device for a vehicle, which is adapted to lock / unlock the locking / unlocking device of each door in conjunction with a locking / unlocking operation for locking / unlocking the car. Storage means for storing that after automatic unlocking, locking detection means for detecting the presence or absence of an operation for automatic locking, required depending on the stored contents of the storage means and the detection state of the locking detection means Along with measuring the passage of time, the measurement value is returned to the initial value when any of the doors is opened during the time measurement, and after that, when all the doors are closed again, the time measurement means that starts time measurement, When the storage means, the locking detection means and the time measuring means are in a required state, by providing the locking / unlocking device control means for controlling the locking / unlocking device of each door to the locked state,
The above problems are solved. [Operation] After performing the locking operation for locking the vehicle, while measuring the required time from the time when the last door is closed,
Even if the door is opened or closed during the time measurement period, the time measurement value is returned to the initial value and the time measurement starts from the time when the last door is closed, so the time when the last door is always closed. Each door can be opened and closed freely for a fixed period of time. [Example] FIG. 1 shows an outline of an automobile to which the present invention is applied. The entire vehicle (A) is locked by locking each door (B) so that it cannot be opened. Among the doors (B), the door (B ') on the driver's seat side is the main door in the automatic locking control, and the other doors (B) are
The door (B ') on the driver's side is locked. The door lock device (C) of each door (B) (B ') is an electric locking / unlocking device equipped with an electric actuator (D). The door lock device (C) disables or disables the operation of the door handle (E) from outside the vehicle after the electric actuator (D) operates in the locking direction, and the door (B)
(B ') is locked. Even when the doors (B) and (B ') are locked, the operation of the locking / unlocking knob (F) from inside the vehicle is effective. A hand operation switch (1) for locking and unlocking the other doors (B) from inside the vehicle is provided inside the door (B ') on the driver's side. When the door (B ') on the driver's seat side is locked from the outside of the vehicle to lock the vehicle, the driver's seat side door lock detection switch (2) for detecting the locked state
Is provided. When the driver's door (B ') is locked from the outside of the vehicle or when the lock is confirmed, it is the starting point for automatically bringing the other doors (B) into the locked state. The switch (2) detects the time when the lock is confirmed. At the time of locking operation, the switch installed on the key cylinder,
Alternatively, it can be detected by a switch or the like provided on the door handle. The lock detection switch (2) may be a key cylinder or a door handle switch. Also,
The lock detection switch (2) may be a dedicated switch operated outside or inside the vehicle when locking the vehicle. Each door (B) is provided with a door opening detection switch (3) for detecting the opening of the door. FIG. 2 is an electric circuit in one embodiment of the present invention,
FIG. 3 is a flowchart of the operation. In this flowchart, the open / closed state of the switches and the like is shown in a time series manner. When the hand-operated switch (1) for locking and unlocking is operated to the unlocking side and the unlocking contact (1a) is closed, the voltage of the power supply (4) is applied to the output side of the unlocking control circuit (5). ), Thereby operating the transistor (6) and the relay (7) to drive each motor (8) in the unlocking direction. The motor (8) corresponds to the electric actuator (D) of each door (B). When the hand operation switch (1) is operated to the lock side and the lock contact (1b) is closed, the output voltage thereof activates the lock control circuit (10) via the OR gate (9), whereby the transistor is turned on. (11), activate the relay (12),
Each motor (8) is driven in the locking direction. When the hand operation switch (1) is operated to the unlocking side, the high level voltage of its output (hereinafter referred to as state [1]) is
The flip-flop circuit (13) is set and its output is set to [1]. The output signal of the flip-flop circuit (13) is the same signal as it is, and the signal inverted through the inverter (14)
It is given to the inputs of AND gates (15) and (16) respectively. The output signals of the lock detection switch (2) are given to the inputs of the AND gates (15) (16). AND gates (15) (16) are lock detection switches (2)
Is closed, the locked state is detected, and when the output signal is [1], the inputs of either one of the gates match according to the output state of the flip-flop circuit (13). The flip-flop circuit (13) outputs the output when it is reset.

Since it is set to [0], when the lock detection switch (2) is closed, the AND gate (16) on the inverter (13) side outputs the output signal of [1], and the signal is the OR gate (17) and the OR gate (17). After passing through (9), the lock control circuit (10) is activated. When the flip-flop circuit (13) is set and the output is [1], the AND gate (15) outputs the output signal [1] when the lock detection switch (2) is closed, and the timer circuit Trigger (18). The timer circuit (18) measures a fixed time (T) from the time when it is triggered, and then outputs an output signal in the state [1], which signal passes through the OR gates (17) (9). Then, the lock control circuit (10) is activated. When any of the doors (B) other than the driver side door (B ') is opened, the timer (18) closes the door open detection switch (13) that detects the opening of the door (B). , Reset by its output signal. The flip-flop circuit (13) stores whether or not the unlocking operation is performed by the hand operation switch (1), and the flip-flop circuit (1
This flip-flop circuit (13) when 3) is set to the output [1] remembers that the automatic unlocking operation has been performed from the inside of the vehicle. This storage state is obtained when the vehicle speed sensor (19) is closed and it is detected that the vehicle has reached a certain speed or more, or when the timer circuit (18) has passed a certain time (T), the lock control circuit ( This continues until the flip-flop circuit (13) is reset via the OR gate (20) when the signal for activating 10) is output. The circuit shown in FIG. 2 operates as shown in the flow chart of FIG. The locking / unlocking operation by the hand operation switch (1) is immediately executed without delay. At that time, if the unlocking operation is performed, the output of the flip-flop circuit (13) which is a memory circuit is
It is set to become [1]. After that, the driver's side door (B ') was closed.
When the door (B ') is locked from the outside of the vehicle by a knob (keyless lock operation) or key operation, the lock detection switch (2) is turned on, and preparations for locking the other doors (B) are completed. To do. Generally, at this point, each electric actuator (D) is operated regardless of the open / closed state of each door. In the present invention, if the memory content of the memory circuit is [1] from the time when the preparation for locking is completed, the time measurement is advanced while checking the state of [1], and nothing happens during that time. For example, after a certain time (T) seconds, the doors (B) are automatically locked and the automobile is locked. Furthermore, if any of the doors (B) is opened before the timer circuit (18) reaches a certain time (T), the timer circuit (18) is reset and the time measurement is returned to the initial value. Stop, and then the time measurement is restarted from the time when all the doors (B) are closed, and the fixed time (T) thereafter.
After a second, each door (B) is automatically locked. In addition, the timer circuit (13) is reset to the initial value each time any of the doors (B) is opened during the time measurement, and automatic locking is not executed during that time. When the door (B) is closed, it is not necessary to confirm the locking / unlocking position of the locking / unlocking knob (F). The locking / unlocking knob (F) is in the locking position when the automatic locking is executed. FIG. 4 shows a flowchart suitable for a program for performing the same control as the circuit of FIG. 2 by a microcomputer, and each step shown in the figure is a step of performing the same control as in FIG. When controlled by a microcomputer, the open / closed states of the hand operation switch (1), lock detection switch (2), door open detection switch (3), vehicle speed sensor (19), etc. are appropriately set for each input port of the microcomputer. Assigned and examined. The memory content of the memory circuit is an unlock flag which is set to [1] when the hand operation switch (1) is unlocked. The unlock flag is checked at the beginning of the control loop as in the case of checking the output state of the memory circuit, and while the unlock flag is [1], the vehicle speed sensor (19) and each door (B) are checked. While checking the open / close state, the timer count value is looped so as to increase, and when the count value reaches a constant value (N), automatic locking is executed. When any of the doors (B) is opened during the timer counting period, the count value of the timer is reset to 0 and returned to the initial value. After that, the count is increased from the time when all the doors are closed again, and when the count value reaches a constant value (N), automatic locking is executed. [Effect of the Invention] According to the present invention, after performing the locking operation for locking the vehicle by locking the door on the driver's side prior to each of the other doors, it is necessary to perform the operation from the time when the last door is closed. Even if the door is opened and closed during the time measurement period, the time measurement value is returned to the initial value, and the time measurement starts from the time when the last door is closed after that. Since each door can be freely opened and closed for a certain period of time after the door is closed, the passengers can get off the vehicle and the degree of freedom in opening and closing doors can be increased regardless of the locking operation by the driver. It is convenient and secure. Furthermore, since the period during which the doors can be freely opened and closed is always a fixed time after the last door of each door is closed, it is easy to predict when the car will be locked. Yes, the driver or passenger can leave the car with peace of mind.
