Problems solved by technology

[0002] When existing vehicles are parked, the method of electrically maintaining the parking force is usually used. This parking method not only requires power supply throughout the process, but also consumes more energy. At the same time, the parking force is completely dependent on the power output. The stability of the power output greatly affects the parking. car reliability
When the power of the vehicle is low, it is difficult to achieve long-term stable parking, and the safety of the vehicle, the safety of nearby personnel and the property safety of the owner are difficult to be effectively guaranteed

Embodiment

[0038] like figure 1 As shown, the parking and unparking control method of this embodiment is realized by the parking controller. The parking controller obtains the torque required for the parking brake according to the slope information of the vehicle and the vehicle information processing, and according to the The required torque is processed to obtain the required caliper clamping force and stored, and the required motor output current is obtained according to the caliper clamping force processing, and the motor output is controlled according to the required motor output current, so that the motor output can just meet the caliper to complete the vehicle parking on the ramp The purpose is to calculate the different parking forces required by the vehicle on different slopes in real time and accurately, so that the vehicle can stop stably. And stop driving the motor according to the output of the motor, the mechanical structure of the caliper maintains the current state and se...

Abstract

The invention discloses a parking and unparking control method which is realized through a parking controller, the parking controller obtains a torque required by parking braking according to information of a ramp where a vehicle is located and vehicle information, obtains a required caliper clamping force according to the torque required by parking braking and stores the required caliper clamping force; the required motor output current is obtained according to the processing of the clamping force of the calipers, the motor output is controlled according to the required motor output current, the driving of the motor is stopped according to the motor output condition, and the current state is kept by the mechanical structure of the calipers and a parking completion signal or a fault prompt signal is sent; in the releasing process, the releasing distance is obtained according to the stored clamping force of the calipers, and motor output is controlled. The parking and unparking control method has the advantages of being simple in step, high in automation degree, good in maintaining effect, small in needed energy and the like.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a parking and unparking control method. Background technique [0002] When existing vehicles are parked, the method of electrically maintaining the parking force is usually used. This parking method not only requires power supply throughout the process, but also consumes more energy. At the same time, the parking force is completely dependent on the power output. The stability of the power output greatly affects the parking. car reliability. When the power of the vehicle is low, it is difficult to achieve long-term stable parking, and the safety of the vehicle, the safety of nearby personnel, and the property safety of the owner are difficult to be effectively guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a parking and unparking control method with ...
