Problems solved by technology

[0004] In particular, the distribution ratio of the front and rear axle torque will also directly affect the slip ratio of the wheels, which in turn will affect the steering characteristics and stability of the vehicle
Therefore, how to provide additional yaw moment to maintain vehicle stability by controlling the wheel slip rate is full of challenges in the practical engineering application of front and rear axle distributed drive electric vehicles

Embodiment Construction

[0067] The present application provides a method and device for controlling vehicle stability, which is used to provide an additional yaw moment to maintain vehicle stability for a front and rear axle distributed drive electric vehicle by controlling the wheel slip rate, so as to control the front and rear axle distributed drive electric vehicles. lateral stability. Among them, the method and the device are conceived based on the same technology. Since the principle of solving the problem of the method and the device is similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0068] Hereinafter, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

[0069] 1) The working condition of the vehicle, that is, the working condition of the vehicle, can also be called the steering characteristics of the vehicle. It is mainly divided into three types: neu...

Abstract

The invention discloses a method and equipment for controlling the stability of a vehicle. The method can be applied to the field of intelligent vehicles such as intelligent driving / automatic driving,and is used for controlling the lateral stability of a front-rear-axle distributed driving vehicle. According to the method, the yawing motion of the vehicle is considered, and the yawing moment foradditionally maintaining the transverse stability of the vehicle is provided for the vehicle in a front and rear axle slip rate compensation mode, so that the transverse stability of the vehicle is controlled, and the stability of the vehicle in the driving process is improved.

Description

technical field [0001] The present application relates to the technical field of smart cars, in particular to a method and device for controlling vehicle stability. Background technique [0002] At present, an electronic stability program (ESP) of a vehicle generally generates braking force vectors on the left and right wheels of the vehicle to control the generation of additional yaw moment, so as to improve the stability of the vehicle. For example, when the steering force of the vehicle is insufficient, the vehicle can use ESP to brake the inner rear wheel to generate an additional yaw moment in the same direction as the steering direction, so as to ensure the stability of the vehicle and drive according to the driver's desired trajectory, such as figure 1 shown in the left figure. For another example, when the steering force of the vehicle is too much, the vehicle can use ESP to brake the outer front wheel to generate an additional yaw moment opposite to the steering sc...
