A device for determining amass of a vehicle includes vehicle height sensors respectively mounted on left front and rear wheels or respectively mounted on right front and rear wheels to sense a vehicle height of the vehicle, a passenger detecting sensor for sensing the number of passengers boarded the vehicle and boarded locations of the passengers, and a controller that calculates a load based on the vehicle height, calculates a load conversion factor based on each offset set based on a boarded location of each passenger and the number of passengers, and calculates a mass change amount based on the load and the load conversion factor. The device may determine an accurate mass of the vehicle when the vehicle height sensors are not mounted on all four wheels, improve a performance of the vehicle by reflecting the determined mass to vehicle control, and reduce tuning parameters for vehicle control.

In an embodiment an apparatus for controlling a height of a vehicle includes a seat having a seat unit and a backrest unit, the seat unit movable in directions of two or more axes, a control module configured to determine a position of the seat in a state in which a driver is seated, estimate a body shape of the driver based on the position of the seat, calculate a vehicle height adjustment parameter based on the body shape and generate a suspension control signal for adjusting a vehicle height based on the vehicle height adjustment parameter and a suspension driving device configured to control a suspension based on the suspension control signal.

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.

Aspects of the present invention relate to a method and to a control system for controlling an active suspension of a vehicle, the control system comprising one or more controllers, the control system configured to: determine whether a transient suspension disturbance to the vehicle is from within a cabin of the vehicle; and control a variable force parameter of the active suspension in dependence on whether the transient suspension disturbance is from within the cabin of the vehicle.

An anti-roll bar for a vehicle. The anti-roll bar includes a first bar portion for connection to a left-side wheel suspension of the vehicle and a second bar portion for connection to a right-side wheel suspension of the vehicle, and an actuator unit connecting the first bar portion and the second bar portion to each other for transferring torque between the first bar portion and the second bar portion. The actuator unit has a first selectable mode providing a first predetermined torque ratio between the first bar portion and the second bar portion, and a second selectable mode providing a second predetermined torque ratio between the first bar portion and the second bar portion. The first torque ratio and the second torque ratio are different from each other.
