Problems solved by technology

However, due to the high difficulty of processing and assembly process and mechanical wear during use, if the actual physical position of the P gear mechanism deviates greatly from the pre-stored value of the P gear controller, the consistency of the physical stroke of the P gear mechanism cannot be guaranteed. , may cause the position to be lost or the implementation is not in place, so that the P gear controller cannot driv

Abstract

The invention provides an electric car and a control method of a P gear of the car. The electric car comprises a P gear mechanism, a P gear driving mechanism, a position sensor, a P gear controller and a storage, the storage is used for storing target position data of the P gear mechanism, the P gear controller is used for controlling the P gear driving mechanism to drive the P gear mechanism to move to the target position according to the target position data, the position sensor is used for sensing motion of the P gear mechanism when the P gear mechanism is driven and outputting a position sensing signal to the P gear controller, and the P gear controller is used for obtaining actual position data of the P gear mechanism according to the position sensing signal and updating the target position data of the P gear mechanism according to the actual position data.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle and a P gear control method thereof. Background technique [0002] In recent years, electric vehicles (including pure electric vehicles, hybrid vehicles, fuel cell electric vehicles, range-extended electric vehicles, etc.) have developed rapidly, and more and more people have entered the field of vision of the general public. [0003] Generally, in existing electric vehicles, the P gear controller has defined each position of the physical stroke of the P gear mechanism at the factory, and the parking position, unlocking position and other information are preset in the P gear controller. However, due to the high difficulty of processing and assembly process and mechanical wear during use, if the actual physical position of the P gear mechanism deviates greatly from the pre-stored value of the P gear controller, the consistency of the physical stroke of the P ge...
