  • Patent number: 11951966
    Abstract: A steering control system for a commercial vehicle having a braking system to brake dissymmetrically wheels. The steering control system, including a sensor unit and a control module, is configured to detect a braking request or deceleration of the vehicle and/or to detect a lateral offset and to generate a brake indication signal and/or steering demand. The control module is configured to receive the brake indication signal and/or steering demand. If the steering demand is below a predetermined threshold value, the control module is configured to generate the steering signal only if the brake indication signal indicates a braking request. If the steering demand exceeds the predetermined threshold value, the control module is configured to generate the steering signal even if the brake indication signal indicates no braking request. The control module provides the steering signal to the braking system to brake the vehicle dissymmetrically to steer the vehicle.
