Abstract
A suspension control apparatus for an automotive vehicle has a plurality of suspension units which are disposed between each of the wheels of the vehicle and the vehicle body. An acceleration sensor measures the lateral acceleration of the vehicle body. A contol unit corrects the output of the acceleration sensor for drift of the neutral point of the sensor from a prescribed value. Based on the corrected output, the control unit controls the suspension units so as to suppress rolling of the vehicle body.
Claims7
A suspension control apparatus for an automotive vehicle comprising:
- attitude-adjusting means for adjusting the attitude of a body of a vehicle;
- an acceleration sensor which senses the acceleration of the vehicle body and produces a corresponding output signal, said output signal having a neutral point corresponding to no acceleration;
- correcting means for correcting the output of said acceleration sensor for drift of the neutral point from a predetermined value;
- and
- control means for controlling said attitude-adjusting means in accordance with the corrected output of said acceleration sensor so as to suppress a motion of the vehicle body caused by the acceleration which is sensed by said acceleration sensor.
A control apparatus for an automotive vehicle comprising:
- a plurality of adjustable fluid suspension units which can be made to expand or contract by respectively supplying or discharging a fluid therefrom, each of said suspension units being disposed between a wheel of a vehicle and a body of the vehicle and supporting the vehicle body with respect to the wheel;
- fluid-supply means for supplying a pressurized fluid to said suspension units;
- an acceleration sensor which senses the lateral acceleration of the vehicle body and produces a corresponding output signal, said output signal having a neutral point corresponding to no acceleration;
- a speed sensor which senses the speed of movement of the vehicle;
- a height sensor which senses the difference between the heights of the left and right sides of the vehicle body;
- correcting means for correcting the output of said acceleration sensor for drift of the neutral point from a predetermined value;
- and
- control means responsive to said speed sensor, said height sensor, and the corrected output from said correcting means for calculating the rolling condition of the vehicle body caused by the lateral acceleration of the vehicle and controlling said fluid supply means so as to suppress the rolling of the vehicle body.
