The invention relates to the technical field of new energy vehicles, and provides a parking control method and device, a vehicle control unit and a new energy vehicle. The parking control method comprises the steps of judging whether a single-pedal mode is activated or not; determining whether a deceleration control condition is satisfied when the single pedal mode is activated; under the condition that the deceleration control condition is met, controlling the new energy vehicle to run in a deceleration mode; in the process of controlling the new energy vehicle to decelerate, judging whether a condition of sending a braking request to a motor controller is met or not; under the condition that the condition of sending the braking request to the motor controller is met, sending the braking request to the motor controller; and under the condition that the new energy vehicle is in the braking mode and the vehicle speed of the new energy vehicle is smaller than the third preset value and lasts for third preset time, sending a parking request to the electronic hand brake, so that the new energy vehicle is in the parking mode. According to the invention, the vehicle can be stably stopped and parked in a single-pedal mode.
Description
technical field [0001] The present invention relates to the technical field of new energy vehicles, in particular to a parking control method and device for new energy vehicles, a vehicle controller, and new energy vehicles. Background technique [0002] With the development of new energy vehicle technology, the concept of "single pedal" control has gradually emerged in the new energy vehicle industry in recent years, that is, the acceleration-constant speed-deceleration control of the vehicle can be realized through one accelerator pedal. The "single-pedal" control method can reduce the frequency of use of the brake pedal, thereby improving the energy utilization rate and driving experience of the vehicle, and reducing driving fatigue. In the related art, there is no effective strategy for the deceleration control performed in the "single-pedal" mode. Contents of the invention [0003] In view of this, the present invention aims to propose a parking control method for ne...
