Abstract

The invention discloses a method for controlling P-gear parking used for a vehicle. The method comprises the following steps: when a vehicle is on a ramp, obtaining current gradient of the ramp where the vehicle is on; according to the current gradient of the ramp where the vehicle is on, calculating delayable locking time when the vehicle is shifted in a P-gear; in the delayable locking time, controlling an electronic parking brake (EPB) system of the vehicle to operate, and after the EPB system operates, controlling the vehicle to execute P-gear locking operation. The method for controlling P-gear parking can reduce acting force between a P-gear lock cylinder and a P-gear lock slot when a vehicle parks on a ramp, so as to prevent abnormal sound caused by P-gear unlocking when the vehicle parks on the ramp. The invention also discloses a system for controlling P-gear parking used for a vehicle, and the vehicle with the P-gear parking control system.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a P-range parking control method for a vehicle, a P-range parking control system for a vehicle, and a vehicle with the P-range parking control system. Background technique [0002] With the development of society, cars have become an indispensable means of transportation in people's daily life. With the continuous improvement of people's living standards, people's requirements for cars are becoming higher and higher, especially for the user experience of cars and the safety of cars. [0003] At present, the maturity of P gear parking system technology makes it widely used in the automotive field. However, if the car is parked on a slope through the P file parking system, a large abnormal noise will be generated due to the unlocking of the P file when the car starts on the slope, which greatly affects the user experience and reduces the user experience of the car.
