Abstract

The present invention discloses a key-free starting control system and its operation method. Said system includes starting push-button / switch, engine controller, starting relay, redundant neutral switch and starting motor. The engine controller can be used for monitoring the signal of starting push-button / switch, automatic speed change controller and redundant neutral switch and controlling closing or breaking of starting relay. The described redundant neutral switch can be parking neutral switch, also can be neutral switch relay. Besides, said invention also provides the concrete steps of said system operation method.

Description

technical field [0001] The invention relates to a starting control system of a vehicle, and also relates to a method for realizing the starting control system. Background technique [0002] Keyless start means that the driver only needs to press a start button on the car panel or remote control, and the engine controller will automatically start the engine. The keyless start has the characteristics of easy operation and fashion. [0003] Keyless start requires the engine controller to fully control the start and stop of the starter motor: the engine controller receives the start signal sent by the start button, judges the start condition, controls the starter motor to run, and completes the engine start action; after the engine is started successfully, the engine control The starter also needs to stop the starter motor. [0004] A complete keyless start control system needs to solve the following problems: [0005] First, ensure starting safety. The starter motor of a tr...
