Abstract

The invention discloses a ramp parking control method and system of an electric vehicle and the electric vehicle with the system. The method comprises the steps that when the electric vehicle is started and stopped at a ramp, a vehicle controller collects various signals of the electric vehicle, generates various instructions according to the collected signals and sends the instructions to a motor controller; the motor controller collects various information of a motor and estimates output torque needed by the motor when the electric vehicle is parked at the ramp according to the collected information; the motor controller judges whether the motor meets the condition of entering a zero-rotating speed control mode or not according to the instructions sent by the vehicle controller and the current state of the motor; if yes, the motor controller takes the estimated torque as an initial output torque command; torque needed by the motor when the electric vehicle is parked at the ramp is regulated through a proportional integral controller, and according to commanded torque, the motor is controlled to perform torque output, and the rotating speed of the motor is regulated to zero. According to the method, the vehicle ramp starting and stopping safety and the driving comfort can be improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method for parking on a slope of an electric vehicle, a control system and an electric vehicle with the system. Background technique [0002] At present, electric vehicles are more and more popular due to their environmental protection, energy saving, portability and safety. [0003] However, when an electric vehicle is parked or started on a slope, the driving direction of the vehicle will be inconsistent with the direction of the gear position, which will cause a large sliding distance of the car on the slope, affecting driving safety, and the motor is stable to 0r The time of / min is longer, which affects the comfort of driving. Therefore, how to reduce the rolling distance of the electric vehicle when parking or starting on the slope, improve the safety of the vehicle on the slope, and how to quickly stabilize the vehicle on the slope to improve the drivi...
