Problems solved by technology
[0004] However, in the traditional electronic control braking system, when the drive braking torque signal under normal working conditions is transmitted to the anti-lock brake controller through the CAN network and the wheel speed signal is transmitted to the motor controller, due to the network Time lag produces uncertain delay factors, resulting in reduced or even unstable control performance of the braking system, thereby affecting driving safety

Embodiment Construction
[0045] Automobiles have become an indispensable means of transportation for us in today's society. With the continuous development of the automobile industry, problems such as energy shortage, environmental pollution and traffic safety have become increasingly prominent. With the increasing call for "energy saving and emission reduction" all over the world, solving or even eliminating the safety and energy pollution problems caused by internal combustion engine vehicles is gradually becoming a major issue faced by major automobile manufacturers. Due to the characteristics of high efficiency and low pollution of electric drive vehicles, the development of electric drive vehicles is considered to be one of the most likely methods to solve the above problems, and has become the main research direction of the automobile industry. Distributed electric drive and centralized electric drive are two types of drive forms used by electric drive vehicles. Compared with centralized electri...

The present application relates to an electric control braking system and an electric control braking method. The anti-lock braking control module of the electronically controlled braking system is integrated in the motor controller, and the vehicle controller is used to determine the total target torque under normal working conditions according to the pedal position signal and vehicle speed signal collected by the pedal position sensor, and The general working condition total target torque is sent to the motor controller; the motor controller is used to perform wheel hub motor driving control according to the normal working condition total target torque; Converting the wheel speed signal to perform anti-lock braking control; wherein, the vehicle speed signal includes a signal determined according to the wheel speed signal collected by the wheel speed sensor, and the target conversion of the wheel speed signal includes inputting the hub motor speed signal to the preset The signal obtained after setting the torsional vibration equation. Adopting the electronically controlled braking system of the present application can increase the braking response speed and improve the braking reliability and safety of the vehicle.
Description
technical field [0001] The present application relates to the technical field of electric vehicle control, in particular to an electronically controlled braking system and an electronically controlled braking method. Background technique [0002] Electric drive vehicles have the characteristics of high efficiency and low pollution, and the development of electric drive vehicles can effectively solve the current social energy shortage, environmental pollution and traffic safety issues; and, since distributed electric drive and centralized electric drive are the Compared with the centralized electric drive, the distributed electric drive has the advantages of improving the efficiency of the drive train, reducing the weight of the vehicle and improving fault tolerance. Therefore, it is particularly important to use the distributed electric drive to achieve precise control of the vehicle. [0003] Regarding the electronically controlled braking system of distributed electric dri...
