A mobile drive unit includes a pivot between the front chassis unit and the rear chassis unit, thereby diminishing the total height of the unit.

A dumping vehicle includes a vehicle elevation system for elevating a body of a vehicle. The system can use one or more components of a vehicle as a main support against which a vehicle body is elevated. In certain examples, a suspension device of the vehicle can be used as the main support. The system further includes an elevation device arranged between the suspension device and a vehicle frame and configured to elevate the vehicle body by lifting the vehicle frame against the suspension device.

A regenerative shock absorber that include a housing and a piston that moves at least partially through the housing when the shock is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor, in turn, drives an electric generator that produced electric energy. The electric energy may be provided to a vehicle, among other things. The regenerative shock absorber may also provide ride performance that comparable to or exceeds that of conventional shock absorbers.

A cooperative control module, an adaptive cruise system and a control method thereof, and a vehicle are provided. The adaptive cruise system comprises a vehicle sensor module, a driving environment intelligent sensing module, a vehicle state response estimation module, an adaptive cruise and controllable suspension cooperative control module, and a power control module. The control method of adaptive cruise is optional, one is according to the cruise speed set by the driver, and the other one is according to the cruise comfort set by the driver. In the case of adaptive cruising according to cruise comfort, the optimal cruise speed is intelligently calculated by the adaptive cruise and controllable suspension system based on driving conditions and driver's demands. The controllable suspension is controlled cooperatively during cruising, and the suspension control parameters are adaptively switched according to the performance requirements of the vehicle under different driving conditions.

A method for controlling vehicle motion is described. The method includes accessing a set of control signals including a measured vehicle speed value associated with a movement of a vehicle. A control signal associated with user-induced input is also accessed. The method compares the measured vehicle speed value with a predetermined vehicle speed threshold value to achieve a speed value threshold approach status, and then compares the set of values to achieve a user-induced input threshold value approach status. The method monitors a state of a valve within the vehicle suspension damper, and determines a control mode for the vehicle suspension damper. The method also regulates damping forces within the vehicle suspension damper.

A trailer having a liftable first axle and an air suspended second axle includes a controller, a first valve coupled to the first axle and a second valve coupled to the second axle. The controller receives an air suspension exhaust request signal and a pressure signal from an air suspension bellows coupled to the second axle. The controller transmits an air suspension control signal to the second valve in response to the air suspension exhaust request signal and transmits a lift axle control signal to the first valve to lower the first axle in response to the pressure signal being less than a predetermined pressure value.
