Abstract

The invention provides a PKE (passive keyless entry) vehicle power control system. The PKE vehicle power control system comprises a control device connected with a power device at the input end and having a power supply output end and a control output end, wherein control device includes a main controller and an auxiliary controller communicated with each other; the main controller includes a main supply output end and a main control output end; the auxiliary controller includes an auxiliary supply output end and an auxiliary control output end; the main supply output end and the auxiliary supply output end are connected to the power supply output end after or connection; and the main control output and the auxiliary control output end are connected to the control output end after and connection. The invention also provides another PKE vehicle power control system and a control method. The PKE vehicle power control system provided by the invention has high safety by adopting redundant design.

Description

technical field [0001] The invention belongs to a PKE (Passive Keyless Entry, keyless access control system) controller and a method for controlling its power supply. Background technique [0002] PEPS (Passive Entry & Passive Start) system is based on the traditional remote key start and engine anti-theft, adding a key wireless encryption and decryption identification system, which can save the user from operating the remote control to remotely open and close the car door and insert the key. The key starts the vehicle, which improves driving comfort and has higher safety protection. [0003] Among them, the original ignition lock will be replaced by electronic power management circuit, supplemented by automatic management of vehicle power. The original ignition lock circuit such as figure 1 As shown, ACC, IGN1 (ie figure 1 IG1), IGN2 (ie figure 1 Middle IG2) is the power supply line in different states of the vehicle, START (namely figure 1 Middle ST) is the starter co...
