The invention relates to a self-adaptive power-assisted automobile electric steering control system which is based on an automobile dynamics theory and determines the running state of an automobile through an automobile speed sensor, a torque sensor, a steering wheel angle sensor, an automobile yaw velocity sensor, a lateral acceleration sensor and an automobile body height sensor. And on the basis, the working voltage of a motor and an electromagnetic clutch in the electric steering control system is controlled, and the assisting power, the steering angle and the rotating direction of the motor and the bonding strength of the electromagnetic clutch are changed, so that different steering assisting power is provided by self-adaption to the running state of the automobile, the operation stability of the automobile is maintained, and the running safety of the automobile is improved. The system is simple in structure, convenient to install, low in cost and capable of being widely applied to various automobiles.

    一种自适应助力式汽车电动转向控制系统,以汽车动力学理论为基础,通过车速传感器、转矩传感器、方向盘转角传感器、汽车横摆角速度传感器、侧向加速度传感器、车身高度传感器,确定汽车的运行状态,并以此为基础控制电动转向控制系统中电机、电磁离合器的工作电压,改变电机的助力、转向角度、转动方向以及电磁离合器的结合强度,从而自适应汽车运行状态提供不同的转向助力,维持汽车的操纵稳定性,提高汽车的运行安全。本系统结构简单、安装方便、成本低,可以广泛地应用于各种汽车。
