Abstract:
1. A variable toe angle control system for a vehicle, comprising: a pair of actuators for individually varying a toe angle of a right wheel and a left wheel; a pair of sensors for individually detecting the toe angle of the right wheel and the left wheel; and a control unit for determining a target value for each of the right and left wheels according to operating conditions of the vehicle and supplying a control signal to each of the actuators according to an output of the corresponding sensor and the corresponding target value, wherein when the control unit detects an abnormal operation in a control system of the variable toe angle control system, the control unit actuates the pair of actuators such that the toe angle of the right wheel and the toe angle of the left wheel are zero, and wherein when the control unit detects an abnormal operation in at least one of the pair of actuators, the control unit actuates the other actuator such that the toe angle of the right wheel is symmetric to the toe angle of the left wheel.
