Passive gate control/starter for vehicle

Abstract

A passive gating / starter for vehicle, including fixed terminal in inside of vehicle and portable terminal take along with vehicle owner, the door of a car locking / unlocking or engine start / stop through bidirectional wireless communiction between the fixed terminal and the portable terminal. When a inductive transducer on the on-off module of door knob or key induces passive action of the owner, according to the received inductive signal, power management module in inside of the vehicle uses the fixed terminal in inside of vehicle transmit LF question signal to the portable terminal, after receiving RF responding signal from the portable terminal, demodulating ID code from RF responding signal then transmiting to the power management module, when the power management module judged recived ID code of RF responding signal is consistent with registered ID code, transmiting control signal to electric connecting BCM and EMS, locking / unlocking the door or staring / stoping the engine, thereby in condition of without other operation, autocontrolling action of the door or engine intellectually.

Description

Technical field [0001] The present invention relates to a passive door control / starter for a vehicle. When a vehicle owner holding a portable terminal touches a door handle or presses a start button, a two-way communication is carried out between a fixed terminal located in the vehicle and the portable terminal. After confirming the ID of the portable terminal, the power management module (PMM) that is electrically connected to the fixed terminal will lock / unlock the door through the door module (Lock / Unlock) or start the engine through the key switch module (KeySwitch Module). Stop (Start / Stop). Background technique [0002] Generally speaking, a door control / starter for a vehicle needs to insert a mechanical key into a key slot and rotate it or press an operation button of a portable terminal to lock / unlock the door or start / stop the engine. Therefore, the existing passive door control / starter for vehicles requires the owner to take out the mechanical key or the portable termin...

AI Technical Summary

Problems solved by technology

[0004] The existing passive door control / starter (PASE: Passive Entry&Passive start) needs to continuously maintain two-way communication between the portable terminal and the fixed terminal, thus shortening the service life of the non-set battery of the portable terminal

Moreover, the existing passive door control / starter can automatically lock or unlock the door as long as the owner walks into or away from the vehicle, and the door is easily locked / unlocked without the owner noticing.
