Abstract

The invention discloses a ramp parking control method and system, a storage medium and a vehicle. The ramp parking control method includes the steps that a sampling value of an accelerator signal anda vehicle inclination angle value are obtained; if the sampling value of the accelerator signal is zero and the vehicle inclination angle value is larger than a preset inclination angle value, ramp stabilization torque is obtained, and a drive motor is controlled on the basis of the ramp stabilization torque, so that a vehicle is stabilized on a ramp; ramp stabilization time when the vehicle is stabilized on the ramp is obtained; and if the ramp stabilization time reaches parting preset time, a locking signal is output, an electromagnetic lock arranged on the drive motor is controlled on the basis of the locking signal to lock the drive motor, and therefore ramp parking is achieved. By the adoption of the ramp parking control method, the drive motor is controlled to be locked or unlocked through the electromagnetic lock arranged on the drive motor, in the vehicle ramp parking process, a traditional mechanical parking mode is substituted, and no high requirement for mechanical braking is needed; and the ramp parking process is simply and conveniently operated, dependence on mechanical braking is low, and traveling safety can be improved.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a slope parking control method, system, storage medium and vehicle. Background technique [0002] For cars, trucks, forklifts and other vehicles, the ability to climb up a certain slope and realize parking on a slope is an essential function. Parking on a slope means that the vehicle can be parked on a slope with a certain inclination angle under the action of an external force. When parking a traditional vehicle on a slope, it is necessary to step on the brake to stop the vehicle on the slope, then pull up the handbrake, and rely on mechanical friction to overcome its own gravity to park the vehicle on the slope. If a mechanical brake is used to realize the parking function, the requirements for the mechanical brake are very high, and the operation of the mechanical brake is relatively complicated, which increases the safety of driving. [0003] Especially for a count...
