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 electrically powered suspension system includes: an electromagnetic actuator; an information acquisition unit configured to acquire time-series information related to stroke position of the electromagnetic actuator, information on stroke velocity, and an amount of change in stroke of the electromagnetic actuator and information on a stroke direction based on the time-series information; a damping force calculation unit configured to calculate target damping force based on the information on the stroke velocity; and a drive control unit configured to control driving of the electromagnetic actuator using target driving force obtained based on the target damping force. The damping force calculation unit calculates equivalent friction compensation force based on the amount of change in the stroke and the information on the stroke direction, and corrects the target damping force based on the calculated equivalent friction compensation force.

An electromechanical roll stabilizer for a motor vehicle is disclosed. A housing has a motor unit that has a stator and a rotor integrated therein. A rotor position sensor board and an actuator torque sensor board are arranged between two stabilizer halves. The actuator torque sensor board has a digitization and transmission unit for digitizing the sensed torque and transmitting the digitized torque to a data forwarding module arranged on the rotor position sensor board. The rotor position sensor board has a rotor position detection unit for sensing and digitizing the rotor position and a data processing unit. The sensing of the rotor position can be triggered by at least one command signal of a controller to the rotor position detection unit. The data processing unit is provided to process the sensed measured values.

Systems, methods, and computer-readable storage media for adjusting the steering geometry of a vehicle by using reinforcement learning in series with a neural network to determine when and how to adjust the steering geometry of the vehicle. A system can do this by receiving vehicle information associated with ongoing movement of the vehicle, and executing a reinforcement learning model using that vehicle information. The outputs of the reinforcement learning model can include a current driving cycle of the vehicle and a current application of the vehicle. The system then executes a machine learning model, where inputs to the machine learning model can include the outputs of the reinforcement learning model and the vehicle information. The outputs of the machine learning model can then include a wheel alignment signal.

The electromagnetic suspension apparatus includes: an electromagnetic actuator provided in parallel with a spring member between a vehicle body and a wheel of a vehicle and configured to generate driving force involving vibration damping of the vehicle body; an information acquisition unit configured to acquire, through a high-pass filter, time-series information about a stroke position of the electromagnetic actuator; and an ECU configured to calculate target driving force of the electromagnetic actuator and use the calculated target driving force to execute driving force control of the electromagnetic actuator. The ECU corrects the target driving force such that when the stroke position on the basis of the high-pass-filter-processed time-series information, from which low-frequency components (steady state deviation) have been removed, is present in a neutral region including a neutral position, spring force of the spring member is made weaker than when the stroke position is present in a non-neutral region.
