A system for controlling a suspension of a vehicle includes a plurality of sensors, an anti-roll moment module configured to determine a front-to-total anti-roll moment distribution based on at least a first operating parameter of the vehicle, at least one suspension actuator, and a suspension control module configured to control the at least one suspension actuator based on the determined front-to-total anti-roll moment distribution. A method of producing an anti-roll moment distribution module for a vehicle includes determining understeer characteristics of the vehicle, determining a maximum lateral acceleration of the vehicle, adjusting the understeer characteristics based on the determined maximum lateral acceleration, determining reference understeer characteristics, determining a plurality of reference yaw rates and a plurality of feedforward contributions using a non-linear quasi-static model of the vehicle, storing the reference yaw rates in a first look-up table, and storing the feedforward contributions in a second look-up table.

A first active stabilizer is installed on a main drive wheel side, and a second active stabilizer is installed on a subordinate drive wheel side. A control device performs load distribution control when a difference in actual driving force between left and right sides of a vehicle exceeds a threshold value during acceleration. A high- side is one of the left and right sides with a greater actual driving force, and a low- side is another of the left and right sides. The load distribution control includes a first mode performed when a vehicle speed is equal to or lower than a first reference value. In the first mode, the control device actuates the first active stabilizer in a direction to lift up the high- side and actuates the second active stabilizer in a direction to lift up the low- side.

An ECU controls the damping force at the time of the expansion movement and contraction movement of the front fork. When detecting at least that the motorcycle is in a state of making a stop and the brake hydraulic sensor shows an output of more than or equal to a predetermined value, the ECU carries out a damping force reducing control for minimizing the damping force of the front fork. The ECU takes the following sequential steps of: sensing a start of an expansion movement of the front suspension after starting the damping force reducing control, sensing a termination of the expansion movement of the front suspension, and terminating the damping force reducing control.

An electrically powered suspension system includes: an electromagnetic actuator provided between a vehicle body and a wheel of a vehicle and configured to generate a damping force for damping vibration of the vehicle body; a wheel speed sensor that detects a wheel speed of the wheel; a wheel speed variation amount calculation part that calculates a wheel speed variation amount on the basis of wheel speed detection values detected by the wheel speed sensor; a 3D gyro sensor that detects sprung state amounts including a sprung pitching action of the vehicle; and a wheel speed variation amount correction part that estimates a variation component in the wheel speed variation amount on the basis of a sprung pitch amount and corrects the wheel speed variation amount so as to reduce the estimated variation component.

A steering control device which applies an assist torque or a reaction torque to a steering member operated by a driver, includes: a torque loss estimation unit which estimates torque loss; and a correction amount calculation unit which calculates a correction amount according to a rack axial force estimation value calculated based on a roll rate when the torque loss estimation unit estimates the torque loss.

A system for a vehicle includes a memory storing a stored driver distribution profile of a driver input parameter and a stored suspension setting corresponding to the stored driver distribution profile. The system further includes a sensor to detect a current value of the driver input parameter. The system further includes a processor communicably coupled to the memory and the sensor. The processor is configured to determine a current driver distribution profile of the driver input parameter based on the current value of the driver input parameter. The processor is configured to determine a current suspension setting based on the current driver distribution profile. The processor is configured to adjust the stored suspension setting to generate a stored adjusted suspension setting corresponding to the current suspension setting.

Method for correcting a height value, measured using a height sensor, of a spring-damper unit of a motor vehicle, wherein the measured height value is corrected by a correction value that is dependent on an acceleration value if the motor vehicle is accelerated in a longitudinal and/or lateral direction, the correction value being adjusted while the motor vehicle is moving.

Suspension systems for recreational vehicles are disclosed. The suspension systems may include at least one adjustable member coupling a sway bar to respective suspensions. The suspension systems may include a torque actuator associated with a sway bar.

A suspension system and associated control methods for improving the effectiveness of driver assistance systems is disclosed where the driver assistance systems can generate and send requests to a suspension control unit (SCU) of the suspension system to actuate (e.g., close) one or more comfort valves in the suspension system to increase the roll stiffness and/or pitch stiffness of the suspension system when the driver assistance systems are taking corrective action. As part of a two-way communication between the suspension control unit (SCU) and the driver assistance systems, the suspension control unit (SCU) communicates target stiffnesses and/or calculated effective stiffnesses to the driver assistance systems, which is used to update the vehicle stability models used by the driver assistance systems.

A suspension assembly for a vehicle having a frame includes a control arm, knuckle, spring, damper, and control module. The control arm is pivotably coupled to the frame. The knuckle is coupled to the control arm and supports a wheel hub for rotation relative to the knuckle. The spring is mounted between the frame and the control arm or the knuckle. The damper has an adjustable damping force and includes a first end mounted to the frame and a second end mounted such that a change in caster angle of the knuckle extends or contracts the damper. The control module is in communication with the damper and configured to adjust a damping force of the damper based on an actual or predicted change in caster angle of the knuckle. The control module is configured to increase the damping force in a direction that resists a change in the caster angle.
