Abstract: A hydraulic actuator includes an energy recuperation device which harvests the energy generated from the stroking of a shock absorber. The energy recuperation device can function in a passive energy recovery mode for the shock absorber to store recovered energy as fluid pressure or it can be converted to another form of energy such as electrical energy.

Abstract: A hydraulic actuator circuit is disclosed for use with first and second shock absorbers, which each may include a piston disposed within a housing. The piston helps define upper and lower working chambers. The circuit may have a motor, a first pump, driven by the motor, and is associated with the first shock absorber and the motor. A second pump, driven by the motor, may be associated with the second shock absorber. A first accumulator communicates with both of the first and second pumps. A first switch valve may assist in controlling fluid flow into the chambers of the first shock absorber. A second switch valve may assist in controlling fluid flow into the chambers of the second shock absorber.

Abstract: A control system and method is disclosed for controlling an active suspension and a leveling system for a motor vehicle. The control system may use estimator, controller and management modules. The estimator module processes measured signals obtained from various components and sensors of the vehicle relating to modal displacements, velocities and accelerations, and calculates derived signals which are used as inputs to the controller module. The controller module calculates the desired damper force for each active damper based on motions of the vehicle body and wheels. The management module translates the desired active damper force into an appropriate set of control signals to control each active damper. These operations are performed for each active damper of the vehicle to control each damper in real time.
