A method for actuating an actuator device of a roll stabilizer for a vehicle. The actuator device has a supply line connection for supplying a supply voltage, a converter for supplying an alternating voltage using the supply voltage, and at least two phase lines for supplying the alternating voltage to actuator connections of an actuator which can be operated using the alternating voltage. The method has a step of reading an interruption signal, which indicates an interruption in the supply of the supply voltage or a deviation from the supply voltage at the supply line connection and a step of providing a protection signal at an interface with a protection device using the interruption signal in order to at least partly prevent a generator voltage which is or can be fed into the phase lines via the actuator connections from being forwarded in response to the protection signal.

The present invention relates to an automatic lift system for a pusher axle and/or a bridge axle of a truck. The automatic lift system raises the pusher axle and/or the bridge axle in the event of a tire blowout or low tire pressure to prevent the truck from swerving, spinning out or rolling over. The system includes a tire pressure sensor integrated to each of two wheels connected to the pusher axle and each of the two wheels connected to the bridge axle. Each tire pressure sensor is connected to a wired circuit and controller area network (CAN) of the truck for electronic communication with a control box. The control box receives tire pressure information from the sensors and transmits axle lift instructions in response to the tire pressure.

A controller controls a suspension apparatus including a variable damper that adjusts a force between a vehicle body and a wheel of a vehicle. The controller includes a first instruction calculation portion and a control instruction output portion. The first instruction calculation portion outputs a first instruction value of a damping force, which corresponds to a first target amount, using a learning result acquired from machine learning in advance by inputting a plurality of different pieces of information. The control instruction output portion limits the first instruction value and outputs it as a control instruction in a case where the first instruction value works in a direction leading to a greater vehicle state amount than a predetermined amount due to control of the variable damper based on the first instruction value.

A closed leveling system for a vehicle includes a suspension system having a number of corners, and each corner includes at least one strut to be coupled to at least one wheel of the vehicle. The closed leveling system also includes a sensor and a master controller in communication with the sensor. The master controller includes a memory device including computer-readable instructions, and a processor in communication with the memory device. The leveling system also includes a power module assembly including a reservoir containing compressible liquid, a pump configured to withdraw the compressible liquid from the reservoir, a dump valve configured to transfer the compressible liquid into the reservoir, and isolation valves. Each isolation valve is associated with at least one corner. The leveling system further includes secondary volumes in selective fluid communication with the reservoir. Each secondary volume is associated with one isolation valve and at least one corner.

An arrangement for a sensor system for vehicles, in particular motor vehicles, for detecting the vehicle speed, the vehicle level and/or the state of the vehicle suspension, having a sensor for measuring the level of a point on a vehicle body and a vibration damper, the vibration damper comprising a first part and a second part which are movable relative to each other, and wherein the level sensor has an excitation coil, at least one receiver coil and at least one electrically conductive element, wherein the excitation coil and the at least one receiver coil are arranged on the second part of the vibration damper and the electrically conductive element is arranged on the first part of the vibration damper or the first part comprises or forms the electrically conductive element.

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 system for testing a suspension system of a vehicle includes an inertial measurement module and a suspension fault detection module. The inertial measurement module is configured to, while the vehicle is not moving, collect sensor data from one or more inertial measurement sensors for different states of the suspension system. The sensor data is indicative of inertial states of the vehicle while the suspension system is in each of the different states. The suspension fault detection module is configured to, based on the sensor data and a set of thresholds, determine whether a fault exists with the suspension system, isolate and identify the fault, and perform a countermeasure based on the detection of the fault.

A wheel support for a motor vehicle, including a main part and a track lever extending from the main part for attaching a track rod via a track rod joint, wherein the track rod joint is fixed or can be fixed to the track lever at an attachment point by a pin on one side of the track lever. A holding protrusion which covers the attachment point forms a securing means for the track rod on the wheel support. The disclosure additionally relates to a method for mounting a wheel support for a motor vehicle.
