System to operate doors of a motor vehicle, uses extra sensor and actuator so passenger door is automatically unlocked as person approaches once driver has been identified as present

摘要

The automatic unlocking system has an emitter (14), a transponder (13) carried by the user, a receiver (17), a processor (15), a capacitive detector (12) sensing the approach of a human, and actuators (38) to release the door locks. Sensors and actuators are provided for each door, so once the correct transponder response has been verified, all doors can be released by a person approaching them.
