Abstract

A keyless vehicle device actuating system for an automotive vehicle combined with an electronic vehicle door unlocking system. Since the vehicle devices, in particular, the engine starting motor can be rotated only when the driver first opens the vehicle doors in accordance with a predetermined code, secondly depresses a plurality of push-button switches arranged within the passenger compartment in accordance with another predetermined code and lastly depresses a starting switch, even if the vehicle doors are opened incorrectly, it is possible to prevent the vehicle which can be started by only depressing a starting switch from being stolen easily. The system according to the present invention comprises a vehicle device actuating signal generating section similar to a door unlocking signal generating section, an ANDing section and a plurality of devices actuated in response to the ANDed signal, in addition to an ordinary electronic door locking system.

Claims

1. A keyless device-actuating system for an automotive vehicle combined with an electronic vehicle door locking system, which comprises:

(a) means for inputting a sequence of vehicle door unlocking coded numbers and at least one vehicle door locking coded number and outputting signals corresponding thereto;

(b) means for inputting a sequence of vehicle device actuating coded numbers and outputting signals corresponding thereto;

(c) means for generating a vehicle door unlocking command signal in response to a sequence of the vehicle door unlocking coded numbers outputted from said means for inputting vehicle door unlocking coded numbers;

(d) means for generating a vehicle device actuating command signal in response to a sequence of the vehicle device actuating coded numbers outputted from said means for inputting vehicle device actuating coded numbers;

(e) means for unlocking the vehicle doors in response to the vehicle door unlocking command signal outputted from said means for generating a vehicle door unlocking command signal;

(f) means for ANDing the vehicle door unlocking command signal and the vehicle device actuating command signal and for outputting a vehicle device control command signal; and

(g) at least one device actuated in response to the vehicle device control command signal from said means for ANDing the two command signals.

2. A keyless device-actuating system for an automotive vehicle as set forth in claim 1, which further comprises means for resetting said ANDing means while the vehicle stops.

3. A keyless device-actuating system for an automotive vehicle as set forth in claim 1, wherein said at least one device actuated in response to the vehicle device control command signal from said means for ANDing the two command signals is an engine starting device.

4. A keyless device-actuating system for an automotive vehicle as set forth in claim 1, wherein said at least one device actuated in response to the vehicle device control command signal from said means for ANDing the two command signals in an ignition device.

5. A keyless device-actuating system for an automotive vehicle as set forth in claim 1, wherein said at least one device actuated in response to the vehicle device control command signal from said means for ANDing the two command signals is a steering wheel unlocking device.

6. A keyless device-actuating system for an automotive vehicle as set forth in claim 1, wherein said at least one device actuated in response to the vehicle device control command signal from said means for ANDing the two command signals is a car-radio.

7. A keyless device-actuating system for an automotive vehicle as set forth in claim 1, wherein said at least one device actuated in response to the vehicle device control command signal from said means for ANDing the two command signals is a power-operated car-radio antenna telescoping device.

8. A keyless device actuating system for an automotive vehicle as set forth in claim 1, wherein said means for inputting a sequence of vehicle door unlocking coded numbers and at least one vehicle door locking coded number is a plurality of push-button switches arranged at an appropriate position on the outside of the vehicle.

9. A keyless device actuating system for an automotive vehicle as set forth in claim 1, wherein said means for inputting a sequence of vehicle device actuating coded numbers is a plurality of push-button switches arranged at an appropriate position within the passenger compartment of the vehicle.

10. A keyless device actuating system for an automotive vehicle as set forth in claim 1, wherein said means for generating a vehicle device actuating command signal comprises:

(a) an octal-binary code converter connected to said means for inputting a sequence of vehicle device actuating coded numbers for converting the octal coded digits inputted from said inputting means into the corresponding binary coded digits;

(b) an address counter connected to said octal-binary code converter for counting up a plurality of the binary-coded signals outputted from said octal-binary code converter whenever said inputting means outputs an address-designation signal in response to the number of signals outputted from said octal-binary code converter;

(c) a memory unit connected to said address counter for outputting a previously stored binary coded signal in response to the address-designation signal outputted from said address counter;

(d) a first comparator connected to said octal-binary code converter and said memory unit for outputting a signal when one of the binary coded door-unlocking signals outputted from said octal-binary code converter agrees with one of the binary coded door-unlocking signals outputted from said memory unit in response to the respective address-designation signal outputted from said address counter;

(e) a counter connected to said first comparator for outputting a signal when said first comparator outputs the predetermined number of binary coded signals; and

(f) a first reset-set flip-flop connected to said counter for outputting a door unlocking command signal when said first counter outputs the signal.

11. A keyless device actuating system for an automotive vehicle as set forth in claim 1, wherein said means for ANDing the vehicle door unlocking command signal and the vehicle device actuating command signal comprises:

(a) a second reset-set flip-flop, the set terminal of which is connected to said means for generting a vehicle door unlocking command signal;

(b) a second AND gate, one input terminal of which is connected to the Q-terminal of said second reset-set flip-flop and the other input terminal of which is connected to said means for generating a vehicle device actuating command signal; and

(c) a third reset-set flip-flop, the set terminal of which is connected to the output terminal of said second AND gate and the Q-terminal of which is connected to said at least one device.

12. A keyless device actuating system for an automotive vehicle as set forth in claim 2, wherein said means for resetting said ANDing means comprises:

(a) a vehicle running detector for outputting a signal while the vehicle stops;

(b) a reset switch;

(c) a third AND gate, one input terminal of which is connected to said vehicle running detector and the other input terminal of which is connected to said reset switch;

(d) a fourth reset-set flip-flop, the set terminal of which is connected to said third AND gate and the Q-terminal of which is connected to said ANDing means, for resetting said ANDing means when said reset switch is depressed while the vehicle stops.

13. A keyless device actuating system for an automotive vehicle as set forth in claim 12, which further comprises a fourth AND gate, one input terminal of which is connected to said means for inputting at least one vehicle door locking coded number, the other input terminal of which is connected to the Q-terminal of said fourth reset-set flip-flop and the output terminal of which is connected to said ANDing means, for resetting said ANDing means in response to a door locking command signal generated after said reset switch is depressed while the vehicle stops.
