Embodiment Construction

[0054] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0055] An embodiment of the present invention provides a method for controlling vehicle movement, and the method is applied to a vehicle control system. When the vehicle moves undesirably, such as sliding or being pushed, the vehicle control strategy will activate the anti-push or sliding function to control the wheels to stop turning.

[0056] Such as figure 1 As shown, the vehicle movement control method described in this embodiment includes...

Abstract

The invention discloses a vehicle movement control method, a control device and an automobile. The vehicle movement control method comprises the following steps: after the vehicle anti-push and the ramp function are activated, the electric angle position of the motor rotor is obtained periodically, wherein, the motor rotor follows the wheel rotation when the wheel is rotated; calculating an electric angular velocity of the motor rotor according to the electric angular position of the rotor; calculating an electrical angular acceleration of the motor rotor according to the electrical angular velocity; determining a target magnetic field strength and a target magnetic field direction of a magnetic field preventing rotation of the motor rotor according to the electric angular velocity and theelectric angular acceleration; According to the target magnetic field intensity and the target magnetic field direction, the intensity and direction of the stator magnetic field of the motor are adjusted. The vehicle movement control method can stop the vehicle movement in a short time when an undesired movement of the vehicle occurs, and can effectively prevent the phenomenon of the vehicle being pushed or sliding down the slope.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a vehicle movement control method, a control device and an automobile. Background technique [0002] With the widespread use of vehicles, people have higher and higher requirements for intelligence in the process of using vehicles. However, during the use of the vehicle, there will be a phenomenon that the vehicle is moved when it is parked, such as being pushed or sliding on a sloped road. This phenomenon brings a lot of inconvenience to the user during the use of the vehicle. Contents of the invention [0003] In order to solve the above technical problems, embodiments of the present invention provide a vehicle movement control method, a control device and a vehicle, which solve the problem of undesired movement of the vehicle. [0004] An aspect of an embodiment of the present invention provides a method for controlling vehicle movement, including: [0005] After the anti-pr...
