PURPOSE:To ensure tha ground contacting force of rear wheel by judging the presence of slip of wheels to reduce the damping force of damper for the suspension systems of front and rear wheels when the slip takes place and the deceleration condition is judged to be present. CONSTITUTION:In runing a vehicle, the output signals of front and rear wheel rotational speed sensors 61, 62 are supplied to the input of a slip judging circuit 50 to figure out the absolute value, of the difference between the rotational speed of front and rear wheels by adder 55, which value is next compared with constant voltage of slip judging criterion by a comparator 57. When said absolute value exceeds the constant voltage, slip occurence, i.e. travelling on low mu road (road having small coefficient mu of friction between tire and road) is judged to generate the ON signal output. This ON signal permits the output signal of a brake detecting means 63 or an accelerator full-closing detecting means 64 passing through OR circuit 65 to butt against AND circuit 66 to turn ON a damper solenoid 70 for a certain time and reduce the damping force of a damper by the output signal of said circuit 66. |
