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 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.

An air suspension control system (ECAS, electronic controlled air suspension) (10) for a utility vehicle, such as a truck or the like, or for a passenger car, includes a main control unit (12) for operating the air suspension control system (10) and at least two auxiliary control units (14) connected to the main control unit (12) via a data link (16). The auxiliary control units (14) each have at least one output (18) for actuating at least one actuator (20) which can be connected to the output (18), in particular an adjustment drive (28) for a valve (30). Furthermore, at least one function for generating control signals at the output (18) can be stored in the auxiliary control units (14), and the main control unit (12) is adapted to call up and/or to parameterize at least the stored functions by transmitting commands via the data link (16).

A suspension monitoring and adjustment system for an off-road vehicle includes a distance sensor arranged to measure shock displacement of a suspension of the vehicle. The system may include an output device configured to output shock displacement data generated by the distance sensor and a processor or programmable circuit operable to produce a visual representation of the shock displacement data output by the output device. The system may include a processor or programmable circuit operable to generate an adjustment signal based on shock displacement data generated by the distance sensor and a suspension adjuster arranged to adjust the suspension of the vehicle in response to the adjustment signal.

A lookahead vehicle suspension system comprises a first independently adjustable suspension system associated with a front wheel; a second independently adjustable suspension system associated with a rear wheel; at least one detector configured to at least assist in delivering electrical signals relating to a front wheel roadway concern, the front wheel roadway concern relating to a roadway defect; and processing circuitry. The processing circuitry is configured to receive, in advance of the rear wheel encountering the roadway defect, both vehicle motion data and the electrical signals, and identify, based on the vehicle motion data and the electrical signals, adjustments with associated timing to be made to the second independently adjustable suspension system to accommodate the encounter of the rear wheel with the roadway defect.

Embodiments described herein relate to the field of transport, in particular motor vehicle transport, and to a controller for a ground connection device of a vehicle: such as a tire, a shock absorber, etc. A controller is able to automatically adjust at least one ground connection device of a vehicle as a function of a predicted item of data characteristic of the current journey of the vehicle on the basis of data supplied by at least one sensor of the ground connection device. Thus, the controller makes it possible to optimize the stability of the vehicle regardless of the journey, in particular on a deteriorated road or on bends, in order to avoid the vehicle leaving its trajectory, by taking into consideration various characteristics in relation to the journeys, such as speed, the state of the road surface, weather conditions, the pressure of the tires, or certain accidents.

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.
