Patent ID: 8463506

Claim:
A rear wheel toe angle control system for changing a rear wheel toe angle of a vehicle by using an electric actuator, comprising: a target rear wheel toe angle setting unit for setting a target rear wheel toe angle; an actual rear wheel toe angle detecting unit for detecting an actual rear wheel toe angle; a drive control unit that drives the electric actuator by a control value based on a difference between the target rear wheel toe angle and actual rear wheel toe angle; a load detecting unit for detecting load acting upon the electric actuator; and a correcting unit for correcting the control value according to the load acting on the electric actuator, wherein the electric actuator includes an electric motor and a power transmission mechanism, and the correcting unit is configured to correct the control value so that an output of the electric motor is greater than a maximum static frictional force of the power transmission mechanism that depends on the load acting on the electric motor.
