The invention discloses an electronic drive-by-wire booster control system which comprises an ECU module, a pedal travel sensor module, a motor module, a hydraulic adjusting module and a pressure sensor module, the ECU module comprises a main control MCU1, an auxiliary control MCU2, a CAN1 and a CAN2, and the motor module comprises a motor, a motor driving module and a motor rotation angle sensor module. The hydraulic adjusting module comprises a main cylinder, a power assisting module and an ESC module. According to the system, firstly, the braking deceleration requirement of a large-tonnage vehicle is met, independent pressurization can be independently achieved, and active pressurization can also be achieved through cooperation with an ESC module, secondly, three pressure sensors are arranged and distributed at oil outlets of a main cylinder and two branch pumps of the hydraulic adjusting module, the pressure of the main cylinder and the pressure of the branch pumps are collected, and the pressure of the main cylinder and the pressure of the branch pumps are calculated. Pressure is fed back in real time, the defects of a vehicle pressure model are effectively overcome, control lag is avoided, and the control precision is improved.
本发明公开了一种电子线控助力器控制系统,包括ECU模块、踏板行程传感器模块、电机模块、液压调节模块和压力传感器模块,所述ECU模块包括主控MCU1、辅控MCU2、CAN1和CAN2,所述电机模块包括电机、电机驱动模块和电机转角传感器模块,所述液压调节模块包括主缸、助力模块和ESC模块。本发明中,首先,本发明满足于大吨位车辆的制动减速度需求,可单独实现自主增压,也可与ESC模块协同合作实现主动增压,其次,本发明设置有三个压力传感器,分布在液压调节模块的主缸和两个分泵的出油口处,对主缸和分泵的压力进行采集,并实时反馈压力,有效弥补车辆压力模型的不足,避免控制滞后,提高控制精度。
