New energy vehicle gear-shifting parking control system

Abstract

The invention relates to a new energy vehicle gear-shifting parking control system. The new energy vehicle gear-shifting parking control system comprises an electronic gear shifter, an electronic parking lock, a charging gun sensor, a brake sensor, a vehicle control displayer, a vehicle speed sensor and a vehicle controller, the vehicle controller is connected with the electronic gear shifter, the electronic parking lock, the charging gun sensor, the brake sensor, the vehicle speed sensor and the vehicle control displayer, the electronic gear shifter comprises an N gear (a neutral gear), a P gear (a parking gear), a D gear (a drive gear) and an R gear (a reverse gear), and the P gear of the electronic gear shifter and the electronic parking lock are in linkage; when the electronic gear shifter is in the P gear, the electronic parking lock is started; and when the electronic gear shifter is switched from the P gear to the other gear, the electronic parking lock is stopped. Compared with the prior art, additional operation is not needed in engaging and disengaging of the P gear when a user drives a vehicle, the electronic gear shifter can be synchronously started and closed, and convenience and safety of driving are ensured.

Description

technical field [0001] The invention relates to the field of control of new energy vehicles, in particular to a control system for shifting and parking of new energy vehicles. Background technique [0002] With the development of automobile technology and the shortage of petroleum energy, new energy vehicles have become the trend of automobile technology development. Most new energy vehicles use a power system composed of a drive motor and a reducer. The forward, reverse and parking of the vehicle are determined and controlled by an electronic controller. In the existing new energy vehicles, the electronic shifter and the electronic parking lock are two independent units, and there is no control logic relationship between them. The user needs to additionally control the electronic parking lock after entering the parking gear. Vehicle locking is different from the handbrake system of a traditional car. The operation of the electronic parking lock is prone to omissions, causi...
