Description

【Technical field】

[0001] The technical field of automobile electronics of the present invention mainly relates to a smart phone-based automobile keyless entry system. 【Background technique】

[0002] The existing car keyless entry systems mainly include the following types:

[0003] 1. The on-board device and the car smart key communicate through radio frequency signals. The on-board device is always searching whether the car smart key is within the effective signal range. For example, when the on-board device detects that the car smart key is within the effective signal range, Then send an unlocking signal to the central control system, if the on-board equipment cannot detect that the car smart key is within the effective signal range within a certain period of time, then send a signal to the central control system to lock the door. The disadvantage of this technology is that the on-board equipment is always on, and at the same time it is always searching for legal keys wit...
