A pet mode door and suspension control system and method includes determining whether a door control action has occurred with respect to a door on the vehicle. When determined that the door control action has occurred, the system and method further includes determining whether a pet mode control action is needed. When determined that the pet mode control action is needed, a suspension control command is sent to suspension control system for raising and/or lowering at least one side of the vehicle and a door control command is sent to a power control unit for opening or closing the door in accord with the door control action.

A control system for a suspension height adjustment mechanism of a vehicle. The suspension height adjustment mechanism comprises a front suspension height adjustment mechanism at a front end of the vehicle and a rear suspension height adjustment mechanism at a rear end of the vehicle. The control system is configured to control the suspension height adjustment mechanism in response to user-generated control signals to: increase the height of at least the rear end of the vehicle to a first predetermined vehicle height corresponding to a High tow hitch height; and decrease the height of at least the rear end of the vehicle to a second predetermined vehicle height corresponding to a Low tow hitch height. Both the first and second predetermined vehicle heights are accessible from one or more other vehicle height that is different to the first and second predetermined heights. Decreasing the vehicle height from the High tow hitch height to the Low tow hitch height comprises the control system controlling the suspension height adjustment mechanism such that the height of the front end of the vehicle is decreased less than the height of the rear end of the vehicle.

A suspension system for use between a frame and a beam axle includes a ride-height adjustment mechanism connectable between the frame and the beam axle. The adjustment mechanism includes an upper spring seat configured to mount to the frame and a lower spring seat configured to mount to the beam axle. A spring is interposed between the upper and lower spring seats. An electromechanical actuator arrangement is configured to move the upper spring seat relative to the frame or the lower spring seat relative to the beam axle so that a distance between the frame and the beam axle can be increased or decreased.

A method for operating an electronically controllable air spring system having air springs includes ascertaining a vehicle velocity of a vehicle and performing a procedure of monitoring a loading procedure and/or a procedure of monitoring an unloading procedure if the vehicle velocity indicates that the vehicle is at a standstill. The method further includes suppressing a level control procedure via the air spring system for a determined time period if at least one pressure difference that is allocated to the air springs exceeds the respective loading pressure limit difference or undercuts the unloading pressure difference and/or a loading criterion or an unloading criterion are met.

A spring and damping arrangement for adjusting the spring rate and the driving position of a motorcycle includes a series circuit having at least one helical spring, an air spring unit, and a hydraulic actuating element. The spring rate of the air spring unit is changeable as a function of a force acting from the outside on the spring and damping arrangement, such that the driving position change resulting from the applied force is compensated by the hydraulic loading of the hydraulic actuating element, such that a defined driving position can be adjusted or maintained.

A control system for a suspension height adjustment mechanism of a vehicle. The suspension height adjustment mechanism comprises a front suspension height adjustment mechanism at a front end of the vehicle and a rear suspension height adjustment mechanism at a rear end of the vehicle. The control system is configured to control the suspension height adjustment mechanism in response to user-generated control signals to: increase the height of at least the rear end of the vehicle to a first predetermined vehicle height corresponding to a High tow hitch height; and decrease the height of at least the rear end of the vehicle to a second predetermined vehicle height corresponding to a Low tow hitch height. Both the first and second predetermined vehicle heights are accessible from one or more other vehicle height that is different to the first and second predetermined heights. Decreasing the vehicle height from the High tow hitch height to the Low tow hitch height comprises the control system controlling the suspension height adjustment mechanism such that the height of the front end of the vehicle is decreased less than the height of the rear end of the vehicle.

An automotive vehicle delivery apparatus includes a traveling showroom structure with sidewalls and a rearwall that enclose an interior vehicle transport space and a substantial majority of which are made up of see-through panes. On board loading rails enable an automotive vehicle to be driven into the interior transport space and doors along the sidewalls enable the automotive vehicle driver door to be opened when the automotive vehicle is within the interior transport space.

A bicycle having a wheel height adjustment structure according to an exemplary embodiment of the present invention includes: a bicycle frame; a hanger where a dropout is formed and rotatably coupled to one side of the frame with respect to a hinge; and an adjusting portion that adjusts a height of the wheel that is engaged to the dropout by rotating the hanger at a predetermined angle.

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.

Techniques are described for compensating for movements of sensors. A method includes receiving two sets of sensor data from two sets of sensors, where a first set of sensors are located on a roof of a cab of a semi-trailer truck and a second set of sensor data are located on a hood of the semi-trailer truck. The method also receives from a height sensor a measured value indicative of a height of the rear of a rear portion of the cab of the semi-trailer truck relative to a chassis of the semi-trailer truck, determines two correction values, one for each of the two sets of sensor data, and compensates for the movement of the two sets of sensors by generating two sets of compensated sensor data. The two sets of compensated sensor data are generated by adjusting the two sets of sensor data based on the two correction values.
