Example Embodiment

[0056] The embodiment of the present invention provides a vehicle control method, a brake control device, and a vehicle. The motor of the vehicle is controlled to generate a braking force for braking the vehicle, thereby realizing active braking. The specific implementation example is as follows:

[0057] figure 1 It is a schematic flowchart of a vehicle control method according to an embodiment of the present invention. figure 1 The method is used in a vehicle powered by a motor and is executed by a brake control device. It should be understood that the vehicle may be an electric vehicle with pure electric power or a hybrid electric vehicle, which is not limited in the embodiment of the present invention. In specific applications, the brake control device can be a smart chip, or a control system on a vehicle, and so on. The method may include the following.

[0058] 110. During the operation of the vehicle, obtain motion data of the vehicle, where the motion data is used to desc...

Abstract

The invention provides a brake control method and device and a vehicle. The method includes the steps that in the vehicle running process, motion data of the vehicle are obtained and used for describing information of the road condition around the vehicle and running information of the vehicle; according to the motion data, whether the vehicle needs to be actively braked or not is determined; under the condition that the vehicle needs to be actively braked, a brake control command is generated and used for controlling a motor to generate brake force used for braking the vehicle; and according to the brake control command, brake control over the vehicle is achieved. By the adoption of the technical scheme of the embodiment, the characteristic that an electric vehicle is electrically driven is used, the motor is controlled to generate the brake force used for braking the vehicle, the situation that brake energy is transmitted to a brake through a transmission device is not needed, design is simple, and implementation is easy.

Description

technical field [0001] Embodiments of the present invention relate to the field of vehicles, and more specifically, to a brake control method, device and vehicle. Background technique [0002] At present, the urban traffic environment is extremely complex, and some unexpected situations may occur at any time during driving, such as sudden braking of the vehicle in front, sudden congestion of side vehicles, pedestrians suddenly breaking into the front of the driving route, etc., making it difficult for drivers of vehicles behind to move quickly. Make a braking action. Therefore, there is a need for a braking system capable of braking independently of the driver's operation. In order to distinguish the types of braking of the vehicle, the braking of the vehicle independent of the driver's operation is called active braking, and the braking of the vehicle due to the driver's braking operation is called passive braking. [0003] In order to solve the above problems, the target...
