An electromechanical vehicle height adjustment unit comprises a displaceable member having an abutment surface for abutment of an end of a vehicle spring or for abutment of a vehicle body and a displacement mechanism coupled to the displaceable member and operative to displace the displaceable member in a height direction. The electromechanical vehicle height adjustment unit comprises a rechargeable energy storage device coupled to the electric motor to store electric energy output by the displacement mechanism during a vehicle lowering operation.

An electromechanical vehicle height adjustment unit comprises an upper spring pad operative to support an upper end of a vehicle spring, a top mount that is displaceable relative to the upper spring pad, and a displacement mechanism coupled to the upper spring pad and the top mount and operative to displace the top mount relative to the upper spring pad in a height direction. The displacement mechanism comprises a rotary-to-linear motion conversion mechanism and an electric motor.

An electromechanical vehicle height adjustment unit comprises a control arm, a lower spring pad operative to support a lower end of a vehicle spring, and a displacement mechanism supported on the control arm. At least a portion of the displacement mechanism is integrated into the control arm. The displacement mechanism is coupled to the lower spring pad and is operative to displace the lower spring pad relative to the control arm. The displacement mechanism comprises a rotary-to-linear motion conversion mechanism and an electric motor.

A method includes detecting whether a request to lower a vehicle is received, and when a request is received, determine potential obstructions under the undercarriage of the vehicle. The method further includes using the map and determining whether any interference with the undercarriage will occur when the vehicle is lowered and lowering the vehicle.

A foldable ramp for wheelchair access to a passenger car door, can include an entry platform which can be arranged an entry positon where the ramp is folded out of the car to allow wheelchair access to the car, a transport position where the entry platform is arranged in the car in an upright position, and a passive position where the entry platform is arranged in the car in a lying positon. The ramp can include a pivoting mechanism to mount the platform to the car, and can include an interlock configured to allow movement of the platform relative to the car and fix the platform relative to at least a section of the car.

A system for dynamically managing individual suspension settings for a vehicle based on a determined suspension mode is provided. Based on the user input and obtained sensor input, the system can then determine a suspension mode for a plurality of individually controllable components by specifying values or commands for each controllable component. A first mode may correspond to a lowering of the plurality of controllable. A second mode may correspond to lowering two controllable components corresponding to the rear wheels of the vehicle and raising two controllable components corresponding to front wheels of the vehicle. A third mode may correspond to a lowering of the plurality of controllable components to effectively drop the height of the vehicle to a threshold point. The system may further implement various validation processes that can validate the determined suspension mode and make further adjustment to individual controllable portions based on load or ground measurements.

Apparatus and methods are described where multiple linear and/or rotary actuators operate cooperatively in, for example, cross-linked arrangements to control the motion of sprung and unsprung masses in a vehicle. The actuators may include linear primary suspension actuators, spring perch actuators and/or rotary roll-bar actuators that, in some operating modes, are driven directly or indirectly by one or more hydraulic machines.
