Active suspension for vehicle

Abstract

Abstract PURPOSE:To reduce both the oscillation of a body and change in attitude at a time of cornering by configurating a device in such a way that a transverse acceleration of the body is detected in order to compute the amount of variations in loads for controlling the increase or decrease in forces acting on between each of wheels and the body. CONSTITUTION:Sensors such as a transverse acceleration sensor 19, a rolling angular acceleration sensor 20, a longitudinal acceleration sensor 21, and a vehicle speed sensor 26 are provided for a vehicle where each of four servo actuators 1 (1fr, 1fl, 1rr, and 1rl) which is provided for each of a front right, a front left, a rear right, and a rear left wheel respectively, is separately controlled so as to control the attitude of a body. Outputs from the acceleration sensor 19 and 20 are inputted into an automatic front/rear load distributor 25 through a change-over switch 24 together with the output from the vehicle sensor 26. Then the amount of variations for loads which act on between each of the front and rear wheels on one side and the body, is computed based on the output from the transverse acceleration sensor. And then the resultant of the said computation is operated based on a ratio corresponding to a vehicle speed so as to distribute it to the front and rear wheels for controlling each of the actuators 1.
