The invention provides a service braking control method, a braking system and a storage medium, and relates to the technical field of vehicles. The braking system comprises an oil supply subsystem, a first proportional electromagnetic valve, a differential supercharger, a first electromagnetic valve and an actuator used for controlling a brake which are in fluid connection in sequence. The differential supercharger is connected with the actuator through a first oil way. A first energy accumulator of the braking system is used for keeping a first preset pressure for an actuator during parking braking; the control method comprises the steps of obtaining a service braking intention; determining whether the brake system is normal based on the oil pressure information and the current signal information of the brake system; when the braking system is normal, the differential supercharger is in fluid connection with the actuator, the first energy accumulator is disconnected with fluid of the first oil way, and the controller adjusts the opening degree of the first proportional electromagnetic valve based on the magnitude of oil pressure needed by the actuator; and when the braking system is abnormal, the controller executes the corresponding service braking mode according to the type of the fault mode. The control method is simple and high in reliability.

    本发明提供了一种行车制动控制方法、制动系统及存储介质,涉及车辆技术领域。制动系统包括依次流体连接的供油子系统、第一比例电磁阀、差动增压器、第一电磁阀和用于操纵制动器的作动器,差动增压器与作动器之间通过第一油路连接;制动系统的第一蓄能器用于给作动器在驻车制动时保持第一预设压力;控制方法包括:获取行车制动意图;基于制动系统的油压信息以及电流信号信息,确定制动系统是否正常;当制动系统正常,差动增压器与作动器流体连接,第一蓄能器与第一油路流体断开,控制器基于作动器所需油压大小,调节第一比例电磁阀的开度;当制动系统异常,控制器根据故障模式的类型执行相应的行车制动模式。本发明的控制方法简单,可靠性高。
