The invention discloses an automobile ESC controller hill starting control system and method and an automobile, and belongs to the technical field of vehicle engineering.In the system, a brake master cylinder oil pressure sensor is installed in a brake master cylinder and used for monitoring the brake oil pressure value P1 applied by a driver; the oil pressure sensor is installed in the HU actuator and used for monitoring the oil pressure value P2 of the wheel cylinder. The longitudinal acceleration sensor is used for monitoring the gradient value of an automobile parking ramp; the ECU processor calculates a wheel cylinder oil pressure value P3 according to the automobile parking ramp gradient value; when the braking oil pressure value P1 is larger than or equal to the wheel cylinder oil pressure value P3, it is considered that the automobile has no backward sliding risk, and the ECU processor does not issue a pressurization instruction to the HU actuator; when the braking oil pressure value is P1lt; and when the monitored oil pressure value P2 of the wheel cylinder reaches the oil pressure value P3 of the wheel cylinder, it is judged that the automobile has the backward sliding risk, the ECU processor controls the HU actuator to pressurize the wheel cylinder, and when the monitored oil pressure value P2 of the wheel cylinder reaches the oil pressure value P3 of the wheel cylinder, pressurization is stopped.
本发明公开了一种汽车ESC控制器坡道起步控制系统和方法及汽车,属于车辆工程技术领域,系统中制动主缸油压传感器安装在制动主缸内,用于监测驾驶员施加的制动油压值P1;油压传感器安装在HU执行器内,用于监测轮缸油压值P2;纵向加速度传感器用于监测汽车停驻坡道坡度值;ECU处理器依据汽车停驻坡道坡度值计算轮缸油压值P3;当制动油压值P1≥轮缸油压值P3时,认为汽车无后溜风险,ECU处理器不对HU执行器下发加压指令;当制动油压值P1<轮缸油压值P3时,则判断汽车有后溜风险,ECU处理器控制HU执行器对轮缸进行加压,当监测的轮缸油压值P2达到轮缸油压值P3值时,停止加压。
