PURPOSE:To keep off any swerve during a driving turn as well as to improve both of turning performance and driving safety, by making rear wheels so as to turn round to a direction increasing the lateral force of tire at deceleration during a car turn. CONSTITUTION:A computer 12 receives a detection signal out of a detection sensor 13 for body's lateral motion such as a lateral acceleration sensor, a yaw rate sensor or the like, and feeds a control signal commensurate to this signal to a servo actuator 8, then performs the rear wheel turn-serrage required. During a car's driving turn, namely, in time of front wheels being turn-steered, if a state of deceleration is the case, it is inputted into the computer 12 which conducts its operational process on the basis of the preset data and makes rear wheels into turn-steerage as far as the specified angle toward where lateral force increases by the operational process of control information, thus a swerve of the car during a driving turn is prevented from occurring. |
