Abstract
The present disclosure relates to a vehicle attitude control device and method. The vehicle attitude control device may include a drive unit configured to independently transmit driving force to each of a plurality of wheels of a vehicle, and a control unit configured to recognize a situation of the vehicle, calculate a driving force (e.g., required) for the situation based on preset (e.g., required) vertical force information corresponding to the situation of the vehicle and vehicle information, and control the drive unit.
Claims20
A vehicle control device for controlling dynamics of a vehicle, the control device comprising:
- a drive unit of the vehicle configured to independently transmit driving force to each wheel of a plurality of wheels of a vehicle;
- and
- a control unit configured to recognize a state of the vehicle, calculate a driving force for the state of the vehicle based on preset vertical force information corresponding to the state of the vehicle and vehicle information, and the control unit is configured to control each wheel of the plurality of wheels, via the drive unit, based on the calculated driving force,
- wherein the vehicle information includes information indicating an instantaneous center of rotation of vehicle suspensions of the vehicle, the vehicle suspensions including a front suspension and a rear suspension, and
- wherein the control unit determines, for each wheel, a direction of the driving force based on a position of the instantaneous center of rotation of the vehicle suspension corresponding to the wheel, to generate a vertical force acting on the vehicle.
