摘要： PROBLEM TO BE SOLVED: To provide a lock control system which is improved in usability by enhancing the detecting accuracy of a mislaid portable unit. SOLUTION: The lock control system has a portable unit 2 and a lock control device 4. The portable unit is provided with a motion detection sensor 1, and upon reception of a predetermined response request radio signal from the motion detection sensor 1, it outputs a response radio signal inclusive of motion detection/non-detection information. The lock control device outputs the response request radio signal to the portable unit 2, and unlocks an electric lock 3 on condition that the authentication of the response radio signal from the portable unit 2 is satisfied and a motion detection signal is present. The portable unit 2 has a sensor output holding section 5 for holding the motion detection signal from the motion detection sensor 1 over a predetermined time, and if the sensor output holding section 5 holds the motion detection signal when the response radio signal is outputted, the portable unit outputs the motion detection signal.

摘要： PROBLEM TO BE SOLVED: To enhance the safety and serviceability of a vehicular keyless entry device. SOLUTION: This device includes a passive entry mode and an active entry mode. In the passive entry mode, communication between portable equipment and a fixed machine is triggered by operation of an outside handle and predetermined control is effected if identification codes are coincident (S11-S18). In the active entry mode, the communication is effected by operation of an unlocking switch or a locking switch and predetermined control is effected if the identification codes are coincident (S19-S21). If locking is done inside the vehicle or if the portable equipment is detected to have been left behind in the vehicle, a function stop flag for stopping the function of the passive entry mode is set (S16). This prevents unauthorized persons from intruding into the vehicle, whereby safety and serviceability can be enhanced.
