<p>PROBLEM TO BE SOLVED: To simplify the constitution of the whole system, particularly reduce the processing load in a receiver in a keyless entry system. SOLUTION: A receiver 2 receives and analyzes unlocking signals from a transmitter 1, decides only coincidence of an ID code, and transfers a functional code to a body ECU 3 without decision of defective or ineffective operation when the ID code coincides. The body EUS 3 indicates locking and releasing on the basis of the functional only when specified operating conditions hold on the basis of a detecting signal from a car-input switch group 5. That is, the receiver 2 does not decide the defective or indefective locking and releasing (the decision of defective or indefective operation) an unlocking device 4, and only the body ECU 3 conducts the decision. Accordingly, an interface for inputting a state signal for defective or indefective decision detected by the car-input switch group 5 is made unnecessary in the receiver 2, and operation defective- indefective decision processing may not be executed, thus reducing processing load.</p> |
