Abstract
Abstract A system is provided for establishing and controlling the attitude of a driver's seat and providing a door lock/unlock control of a vehicle. The vehicle carries an electronic control unit in which driver's identification codes and attitude data for establishing a driver's seat and mirrors are previously stored. A code signal is transmitted from a radio emitter, and is received by a radio receiver mounted on the vehicle. The control unit decodes the received code, and upon finding that it corresponds to one of the codes stored, unlocks the door of the vehicle and automatically establishes the attitude of the seat and the mirrors in accordance with data which is stored in correspondance to the code.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
335 words
A system for controlling a door and driver's seat of a vehicle comprising: a portable code emitter including a plurality of switches and a code generator for producing a code indicative of a particular switch operated; a receiver mounted on a vehicle for receiving said code; a plurality of key switches mounted on said vehicle for indicating and instructing a code, a registration command and an attitude information store command; an automatic seat adjusting mechanism mounted on said vehicle and including at least one electric motor; driver means for energizing each of said motors of said seat adjusting mechanism; an attitude information generator connected to said seat adjusting mechanism for producing a signal indicative of the attitude of a seat; a door lock controlling device mounted on said vehicle; and an electronic control unit connected to said receiver, said plurality of key switches said driver means, said attitude information generator and said door lock controlling device; said electronic control unit comprising electronic processor means and memory means including a read only memory, a read-write memory and a non-volatile, read-write memory; said electronic control unit storing said code indicated with said key switches as a door unlocking code at a predetermined address of the non-volatile, read-write memory in response to a registration command entered with said key switches; said electronic control unit storing the attitude information produced by said attitude information generator at an address of the non-volatile, read-write memory in response to an attitude information store command entered with said key switches, the address corresponding to said door unlocking code stored in the non-volatile, read-write memory; and said electronic control unit energizing said door lock controlling device for an unlocking operation when the portable code emitter produces a code which coincides with said door unlocking code stored in the non-volatile, read-write memory, reading out the attitude information at the address corresponding to said door unlocking code and energizing the driving means for establishing the attitude of the seat as indicated by the read attitude information.
Claim 2
Independent Claim
335 words
A system for controlling a door and driver's seat of a vehicle comprising: a portable code emitter including a plurality of switches and a code generator for producing a code indicative of a particular switch operated; a receiver mounted on a vehicle for receiving said code; a plurality of key switches mounted on said vehicle for indicating and instructing a code, a registration command and an attitude information store command; an automatic seat adjusting mechanism mounted on said vehicle and including at least one electric motor; driver means for energizing each of said motors of said seat adjusting mechanism; an attitude information generator connected to said seat adjusting mechanism for producing a signal indicative of the attitude of a seat; a door lock controlling device mounted on said vehicle; and an electronic control unit connected to said receiver, said plurality of key switches said driver means, said attitude information generator and said door lock controlling device; said electronic control unit comprising electronic processor means and memory means including a read only memory, a read-write memory and a non-volatile, read-write memory; said electronic control unit storing said code indicated with said key switches as a door unlocking code at a predetermined address of the non-volatile, read-write memory in response to a registration command entered with said key switches; said electronic control unit storing the attitude information produced by said attitude information generator at an address of the non-volatile, read-write memory in response to an attitude information store command entered with said key switches, the address corresponding to said door unlocking code stored in the non-volatile, read-write memory; and said electronic control unit energizing said door lock controlling device for an unlocking operation when the portable code emitter produces a code which coincides with said door unlocking code stored in the non-volatile, read-write memory, reading out the attitude information at the address corresponding to said door unlocking code and energizing the driving means for establishing the attitude of the seat as indicated by the read attitude information.
Claim 3
Dependent Claim
43 words
A system according to claim 1 wherein said electronic control unit energizes said door lock controlling device for a locking operation when said code emitter produces a code indicative of the closure of at least one of said switches of said code emitter.
Claim 4
Dependent Claim
67 words
A system according to claim 1 wherein said code emitter is a radio transmitter including a modulator which modulates a carrier signal in accordance with a code generated by said code generator and a transmitting coil for transmitting the modulated carrier signal and wherein said receiver is a radio receiver including a receiving coil and a demodulator which demodulates a code signal from the received carrier signal.
Claim 5
Dependent Claim
57 words
A system according to claim 1 further comprising a plurality of adjustment key switches connected to said electronic control unit for instructing an adjustment of the seat attitude by the automatic seat adjusting mechanism whereby the electronic control unit energizes the automatic seat adjusting mechanism in a direction corresponding to the operation of said adjustment key switches.
Claim 6
Dependent Claim
104 words
A system according to claim 1 further comprising: an automatic mirror adjusting mechanism mounted on said vehicle; an attitude information generator connected to said mirror adjusting mechanism for producing a signal indicative of the attitude of said mirror; and a plurality of adjustment key switches connected to said electronic control unit for instructing said automatic mirror adjusting mechanism to adjust the attitude of said mirror; said electronic control unit storing and reading out the attitude information produced by the mirror attitude information generator at an address corresponding to said door unlocking code whereby said electronic control unit subsequently energizes said automatic mirror adjusting mechanism.
