Outline
The wirecontrolled braking system has gradually replaced the traditional vacuum booster solution and has become the leading technology in the braking field of new energy vehicles. Among them, the integrated ElectroHydraulic Braking (EHB) system, as a form of wirecontrolled braking, relies mainly on basic hydraulic braking and motor regenerative braking to fulfill the driver's braking intention when its EHB module fails. These two braking methods can provide relatively limited braking power, which is difficult to achieve the deceleration effect expected by the driver, to some extent increasing the risk of traffic accidents. In order to comprehensively enhance the driving safety performance of the vehicle, in this paper the Electronic Parking Brake (EPB) system is incorporated as one of the executing mechanisms for driving brakes. When the power assist function of the integrated EHB system fails, the intelligent braking system can, based on the deceleration requested by the driver, send a braking force or deceleration request signal through the vehicle network communication. This process coordinates the motor regenerative braking and EPB braking to work together to enhance the vehicle's deceleration performance, thereby significantly improving braking efficiency. In addition, by implementing multilevel control strategies for the EPB system, the system can meet the needs for different levels of deceleration, which not only optimizes the driving experience and improves comfort but also effectively reduces the probability of traffic accidents.
