The invention discloses an electro-hydraulic steering control method without an angle sensor and a steering system. The control method comprises the steps that the relation between a liquid level signal of hydraulic oil in an oil tank in the electro-hydraulic steering system and an axle steering angle is obtained; during steering control, a liquid level signal of hydraulic oil in an oil tank is obtained, and then the axle steering angle is obtained according to the relation between the liquid level signal and the axle steering angle so as to conduct steering control. While the steering control precision is guaranteed, the cost is reduced, and meanwhile, the problem that the angle sensor is difficult to install due to space limitation when the angle sensor is installed on a vehicle chassis is solved.

    本发明公开了一种无角度传感器的电液转向控制方法及转向系统,所述控制方法包括步骤:获取电液转向系统中油箱内液压油的液位信号与车桥转向角之间的关系;在转向控制时,获取油箱内液压油的液位信号,再根据液位信号与车桥转向角之间的关系,得到车桥转向角以进行转向控制。本发明在保证转向控制精度的同时,降低成本,同时避免角度传感器在车辆底盘安装时因空间受限而带来的安装困难等问题。
