The invention discloses a method for aligning control of an electric power steering system for a vehicle. The method comprises the following steps of: 101, estimating the aligning torque of the vehicle; 103, judging whether the vehicle is in an aligning state; 105, determining related coefficients of vehicle speed of aligning control when the vehicle is in the aligning state; and 107, performing aligning compensation control on a power motor, wherein the method for the aligning control of the electric power steering system for the vehicle can also be quickly realized by the software and hardware combination of Simulink and dSPACE in step 109. According to the method for the aligning control of the electric power steering system for the vehicle, a parameter measured by a rotating angle sensor is not required to be considered, the rotating angle sensor is not required to be equipped for the electric power steering system, and the cost of the vehicle is saved; and moreover, the method for the aligning control of the electric power steering system for the vehicle is also applicable to vehicles on which rotating angle sensors are arranged.
Description
technical field [0001] The present invention relates to the technical field of electric power steering systems, and in particular to a method for back-alignment control of electric power steering systems for vehicles. Background technique [0002] The electric power steering system (EPS) of a vehicle is usually composed of a torque sensor, a vehicle speed sensor, an electronic control unit (ECU), a booster motor, an electromagnetic clutch, and a reduction mechanism. The working principle of the electric power steering system is to monitor the angular displacement of the steering wheel and the torque acting on the steering wheel through the angle sensor and torque sensor installed on the steering gear, combine the monitoring results with the vehicle speed information, and control the booster motor according to a certain algorithm A corresponding torque is generated to assist the driver in turning the steering wheel. [0003] When the driver is driving a traditional non-assis...
