First Claim
Patent Images
1. A motor vehicle comprising:
- a body, wheels for supporting said body, suspension means between said body and respective ones of said wheels;
said suspension means including resistance means which provide resistance to vertical movement of said body with respect to said wheels, adjusting means for adjusting said resistance means of said suspension means to change the resistance, steering angle sensing means for producing steering angle signals, control means for controlling said adjusting means, said control means including means for comparing a last steering angle signal with an averge value of a plurality of steering angle signals produced by said steering angle sensing means during a period of time immediately preceding said last steering angle signal and generating a difference signal denoting the difference between said last steering angle signal and said average value of said steering angle signals, and means for comparing said difference signal with a predetermined difference signal value and for providing a drive signal for operating said adjusting means to increase the resistance of said resistance means when said difference signal is larger than said predetermined value.

Abstract
Suspension mechanisms for motor vehicles include dampers of variable damping powers and air springs of variable spring coefficients so that the suspension characteristics are changed between soft and hard modes. The suspension mechanisms are provided with a controller for producing a control signal only when the differential value between the value of a last steering angle and an average value of steering angles is larger than a predetermined value to change the suspension characteristics to the hard mode. In accordance with this arrangement, the suspension characteristics are changed to the hard mode only when the rolling angle of the vehicle exceeds a predetermined value.
