The method and apparatus of the present invention provide constant force suspension and near constant force Suspension and associated control algorithms, all of which may be utilized in vehicle suspension systems. By using the apparatus of the present invention, a vehicle may be isolated from the motion of a wheel as it follows rough terrain, thereby improving ride quality.

[ What is claimed:] [1.] A constant force or near constant force suspension system, comprising:a vehicle body;a vehicle wheel;an actuator connected between said vehicle wheel and said vehicle body to isolate said vehicle body from surface irregularities by maintaining a substantially constant force

[ What is claimed:] [1.] A constant force or near constant force suspension system, comprising:a vehicle body;a vehicle wheel;an actuator connected between said vehicle wheel and said vehicle body to isolate said vehicle body from surface irregularities by maintaining a substantially constant force on said vehicle body in response to control signals;means for determining and tracking a fictitious reference point, said fictitious reference point representing a desired vertical position of said vehicle body, said fictitious reference point stored within a control system, said means coupled to said control system;first sensing means for measuring actual vertical position of said vehicle body; andsaid control system for developing said control signals, said control signals dependent upon a relative comparison of said fictitious reference point to said actual vertical position, said control system coupled to said actuator.
