Abstract:
1. A vehicle lateral movement stabilizing device comprising frictional force adding means having an actuator and an actuated member for increasing the frictional force of wheels to a road surface by driving said actuated member by said actuator, various sensors or switches including wheel speed sensors, for detecting signals indicating movement and/or turning of the wheels or the vehicle, a controller for controlling the actuation of said actuator based on signals from said sensors, said controller including a lateral movement evaluating portion for calculating by computing values indicating a lateral movement state including movement and turning of the vehicle based on detection signals from said sensors, determining whether the lateral movement value is not less than or not more than a predetermined reference value, and evaluating the lateral movement, said controller sending a control signal based on the results of evaluation to said frictional force adding means to increase the frictional force, whereby controlling the lateral movement in a stable state, and wherein said frictional force adding means are provided for all of the front two and rear two wheels, and wherein if said lateral movement evaluating portion determines that the vehicle is in an understeer (US) tendency, a control signal is sent to the frictional force adding means for the front two wheels and if it determines that the vehicle is in an oversteer (OS) state, a control signal is sent to the frictional force adding means for the rear two wheels to increase the friction coefficient μ.
