DETAILED DESCRIPTION OF THE INVENTION The present invention provides a vehicle in which the door lock can be unlocked by operating an operating section provided on the outside of the vehicle without using a key, and the vehicle load can be operated. The present invention relates to a keyless load operating device for a vehicle that facilitates the operation of a vehicle load when the vehicle is locked.

Conventionally, vehicle door locks are usually unlocked using a key, but since it is convenient to be able to unlock a door lock without using a key, an operation button is provided on the outside of the door and operated. keyless system that allows you to enter the unlock code to unlock the door, and if you want to activate the on-vehicle load such as the trunk, window, or antenna, then operate the operation button specified for each load to activate the load. Load actuation schemes have recently been proposed. (For example, see Japanese Patent Application Laid-Open No. 57-58781). Fig. 1 shows the arrangement of operation buttons provided near the outside handle 1 of the door, where 2 is a key cylinder for unlocking the door lock, 3 to 8 are operation buttons for unlocking and operating the vehicle load, and 3 is a key cylinder for unlocking the door. is the start or cancel button for unlocking or in-vehicle load operation, 4 is the number “1”,
Operation button for inputting ``2'' and unlocking the trunk; 5 is an operation button for inputting numbers ``3'' and ``4'' and specifying a window; 6 is an operation button for inputting numbers ``5'' and ``6''; Operation button for closing the window, 7 is the number “7”,
An operation button for inputting "8" and opening a window; 8 is an operation button for inputting numbers "9" and "0" and specifying a door lock. To unlock the door using the keyless method, first press the cancel start button 3.
(Press once to start, press twice to cancel), then use operation buttons 4 to 8 to select, for example, 5.
Enter the digit unlock code. After that, if there is an on-vehicle load to be activated (for example, unlocking the trunk), the operator presses the operation button 4. As a result, the door is unlocked and the trunk is also unlocked. In this way, the door locks can be unlocked and the vehicle loads can be activated simply by operations from outside the vehicle without using a key. On the other hand, the on-vehicle load can also be operated by operating an operating button or lever provided on or near the instrument, or an operating button provided inside the driver's door.

By the way, if you lend a vehicle that employs such a keyless load operation system to someone else, the other person must use the key to unlock the door and then open the trunk, for example, by using a keyless system installed on the outside of the door. If you want to open the trunk using the on-vehicle load operation button, you must first enter the unlock code and then press the trunk unlocking operation button.If you use the key to open the trunk, you must unlock the trunk located on the instrument. It is necessary to operate the operation button. The former keyless unlocking method requires the unnecessary operation of entering an unlocking code, and the latter method using an operation button depends on the location of the button.
If the button is located near the center of the instrument, a part of the body must be placed inside the vehicle to operate the button, which makes it difficult to operate.

The present invention has been made in view of the above-mentioned problems, and allows door locks to be unlocked from outside the vehicle without using a key by inputting code information for door lock unlocking using a code information input means provided outside the vehicle. In addition, in order to facilitate the driving of on-vehicle loads, if the door lock is unlocked with the key without entering the coded information, the on-vehicle loads other than the door lock can be driven from outside the vehicle. The purpose of the present invention is to provide a keyless load actuation device for a vehicle that can be used in a vehicle.

In order to achieve the above object, the present invention, as shown in FIG. A discriminating means B which compares the stored encrypted information and outputs an unlocking command when both pieces of information match; and a door lock driving means C which drives the door lock to unlock based on the unlocking command from the discriminating means B. , a door lock unlock detection means D provided in the door lock mechanism related parts to detect and output that the door lock is mechanically unlocked;
An actuation command input means E is provided outside the vehicle and outputs an actuation command for actuating an on-vehicle load other than a door lock, and an actuation command input means E is inputted to input an actuation command from the actuation command input means E, and an unlocking command is issued from the discriminating means B. Alternatively, the vehicle-mounted load driving means F drives the corresponding vehicle-mounted load when the output from the door lock/unlock detection means D is inputted.

The present invention will be described below with reference to the drawings, and the embodiment described below is an example in which a door is unlocked and a trunk as a vehicle load is unlocked.

FIG. 2 shows an embodiment of the keyless load actuation device according to the present invention, in which when operating buttons 3 to 8, which serve as coded information input means A provided on the outside of the vehicle and also serve as actuation command input means E, open the door. An electronic lock circuit EL that outputs an unlock signal, a door lock unlock actuator 30 as a door lock driving means C operated by this unlock signal, and an output that detects that the door lock is mechanically unlocked. The vehicle is constructed of a door unlock sensor 40 as a door unlock detecting means D, and a trunk lock actuator 50 as a vehicle load driving means F, which operates a trunk locking mechanism. The electronic lock circuit EL is a circuit that outputs a door lock unlocking signal when a predetermined operation is performed.The electronic lock circuit EL is a circuit that outputs a door lock unlocking signal by a predetermined operation.

and a delay circuit 22 that delays the output of the OR gate 21. In the electronic lock circuit EL, 23 is a timer, 24 is a one-shot multivibrator, and 25 is turned on and off by an unlocking signal. It is a switching transistor.

The door lock actuator 30 has a solenoid, and a switching transistor 25 is connected in series to the energizing coil of the solenoid.

The door lock mechanism is provided in a key cylinder of the door, which is a part related to the door lock mechanism, and outputs a door unlock signal S when the door lock is mechanically unlocked.

Trunk lock actuator 50 operates to unlock the trunk lock mechanism when point M is grounded.

Next, the operation of the keyless load actuating device having the above configuration will be explained.

First, operation buttons 3 to 8 provided on the outside of the vehicle
are pressed in a predetermined order to input the unlocking code, and then the operation button 4 is pressed to input a command to unlock the trunk lock.The output signal from the operation button is converted into binary coded decimal by the BCD converter 11 and sent to the comparator 15. At the same time, it is sent to the address counter 13 via the OR gate 12. As a result, the address counter 13 increments and the address signal corresponding to the pressed button switch is sent to the memory 14. The comparator 15 compares the output signal from the BCD converter 11 and the output from the memory 14, and outputs "1" each time the two match. The output of the comparator 15 is counted by a counter 16. When a 5-digit number is stored in the memory 14, the counter 16 has a value of 5.
A forward counter is used, and when the fifth match signal is output from the comparator 15, the counter 16 that counts this signal sets the RS flip-flop 17. As a result, a door lock unlock signal is output from the Q terminal of the RS flip-flop 17, the switching transistor 25 becomes conductive, the door lock actuator 30 is activated, and the door lock is unlocked.
At this time, if the trunk unlocking operation button 4 is pressed, point M is grounded, and the trunk lock actuator 50 is operated to unlock the trunk.

On the other hand, the output of the address counter 13 is also given to an AND gate 20, and the AND gate 20 functions as an address value detection device, and the last digit, that is, 5
Detect the binary encoded signal of the digit. Push button 3~
When a 5-digit number from 8 is input, AND gate 20 opens, OR gate 21 and delay circuit 2
2 through address counter 13 and counter 16
A reset signal is given to both.

Furthermore, signals from the push buttons 3 to 8 are also given to the retriggerable multivibrator 18 via the OR gate 12. When the retriggerable multivibrator 18 receives an input signal, it produces an output for a certain period of time, and if there is a next trigger input during this certain period of time, the certain period of time restarts from that point. The output will continue as long as ~8 is pressed one after another, but if it is not pressed for a certain period of time, the output will stop. One-shot multivibrator 19 outputs an output at the falling edge of the output of retriggerable multivibrator 18, and provides a reset signal to address counter 13 and counter 16 via OR gate 21 and delay circuit 22. When the RS flip-flop 17 is set by the output of the counter 16, the timer 23 starts operating by the Q terminal output, and after a certain period of time, the one-shot multivibrator 24 generates a reset signal when the output of the timer 23 rises.
This reset signal causes RS flip-flop 1
7 is reset.

Push buttons 3 to 8 provided outside the vehicle in this way
If the door lock unlocking code and trunk lock unlocking command are input using , the door lock will be unlocked and the trunk will also be unlocked.

On the other hand, when the door lock is unlocked with the key, a door unlock signal S is sent from the door unlock sensor 40.
, the RS flip-flop 17 is set and a door lock unlocking signal is output from its Q terminal in the same manner as in the operation of the keyless unlocking method described above. As a result, switching transistor 25 becomes conductive and door lock actuator 30 operates. In this case, since the door lock has already been unlocked with the key, the door lock actuator 30
The operation of is meaningless. On the other hand, if the push button 4 is pressed at this time, the M point is grounded, so the trunk lock actuator 50 is activated and the trunk lock is unlocked.

In this way, when the door lock is unlocked with the key, you can simply input the command to unlock the trunk lock without inputting the door lock unlocking code using pushbuttons 3 to 8 (the door lock unlocking code). The trunk lock can be unlocked without having to enter the key in advance), improving operability.

In the embodiment shown in FIG. 2, the trunk can be unlocked only if the trunk unlock command is input within a certain period of time (time set by the timer 23) after the door is unlocked with the key. The embodiment shown in the figure is designed to enable the trunk to be unlocked at any time after the door lock is unlocked with the key, and the door unlock sensor 40 of the embodiment shown in FIG. A door unlock sensor 60 and a door lock sensor 70 as shown in FIG. 3 are connected, the output of the former being connected to the set terminal S and the output of the latter being connected to the reset terminal R.
A circuit consisting of an RS flip-flop 80 and a switching transistor 90 which is turned on and off by the Q terminal output of the RS flip-flop 80 is connected to the N point of the circuit shown in FIG.

According to this embodiment, when the door is locked, the RS flip-flop 80 is reset by the "H" output from the door lock sensor 70, and when the door is unlocked with a key, for example, the "H" output from the door unlock sensor 60 is reset. '', the RS flip-flop 80 is set and the switching transistor 90 becomes conductive. As a result, when the push button 4 for unlocking the trunk is pressed, the trunk lock actuator 50 is operated and the trunk is unlocked. In this case, the Q terminal output of the RS flip-flop 80 remains "H" and the potential at point N remains zero, so inputting the command to unlock the trunk lock using the pushbutton 4 is equivalent to unlocking the door lock using the key. Any time later.

The above embodiment has been explained using the example of unlocking and unlocking the trunk as an on-vehicle load, but it goes without saying that the present invention can also be applied to other on-vehicle loads such as putting in and out an antenna, opening/closing a window, etc. do not have.

As explained above, the keyless on-vehicle load actuation device for a vehicle of the present invention is provided outside the vehicle, and includes a code information input means for inputting code information for unlocking a door lock, and a code information input means for storing the input code information in advance. a determining means for comparing the encoded information and outputting an unlocking command when the two pieces of information match; a door lock driving means for driving the door lock to unlock based on the unlocking command from the determining means; and a door lock mechanism-related device. door lock release detection means provided on the component to detect and output that the door lock is mechanically unlocked;
an operation command input means provided outside the vehicle for outputting an operation command for operating an on-vehicle load other than a door lock; and an operation command input means for inputting an operation command from the operation command input means and outputting an unlock command from the discriminating means or an unlocking command for the door lock. The vehicle load driving means drives the corresponding vehicle load when the output from the lock detection means is input, so that the door lock can be unlocked from outside the vehicle without using a key by inputting code information for unlocking the door lock. Vehicle-mounted loads other than the lock and door lock can be driven, and vehicle-mounted loads other than the door lock can be driven from outside the vehicle by unlocking the door lock with a key without inputting the coded information. In particular, if you borrow a car from someone else and don't know or forget the code for unlocking the door, it may be difficult to operate the on-board load if the button is located near the center of the instrument. All problems can be solved.
