  • Publication number: 20260116374
    Abstract: Method comprising detecting that the vehicle is performing a transitional maneuver or detecting a braking request or a propulsion torque reduction while the vehicle is driving in a curve at grip limit based on first data indicative of driver intentions and/or vehicle motion state, detecting instability of the vehicle based on the first data, adjusting a torque request to the two clutches in response to the detected instability, wherein the two clutches are arranged to transmit the propulsion torque generated by the propulsion actuator to the wheels based on the torque request and based on the propulsion torque generated by the propulsion actuator, and wherein the torque request is adjusted based on the vehicle motion state and/or driver intentions such that a yaw motion of the vehicle is reduced.

  • Publication number: 20250382996
    Abstract: Embodiments relating to a method for a vehicle comprising two clutches connected to rear wheels of the vehicle and arranged to transmit torque to the rear wheels of the vehicle, the two clutches being connected to a propulsion actuator, the operating method comprising detecting an oversteering situation based on first data indicative of a vehicle motion state, detecting that a propulsion torque generated by the propulsion actuator is above a first threshold based on second data indicative of the propulsion torque generated by the propulsion actuator, and adjusting a torque request to the two clutches, wherein the two clutches are arranged to transmit torque to the rear wheels based on the torque request and based on the propulsion torque generated by the propulsion actuator.

  • Patent number: 11945430
    Abstract: A vehicle motion control system for coordinating and synchronizing a wheel-individual brake system and a power-train torque vectoring actuator system in a vehicle. The wheel-individual brake system includes at least one first actuator for applying a braking torque to individual wheels of the vehicle. The power-train torque vectoring actuator system includes at least one second actuator for applying a torque to individual wheels of the vehicle through a propulsion system. The vehicle motion control system includes a central control function module including a plurality of yaw torque controllers. Each yaw torque controller is configured to receive data including driver inputs and vehicle motion states to determine a respective yaw torque based on the received data for controlling the yaw behavior of the vehicle.

  • Patent number: 11427253
    Abstract: The present invention relates to a method for collision avoidance for a host vehicle, the method comprising: detecting a target in the vicinity of the vehicle; determining that the host vehicle is travelling on a collision course with the target; detecting a user initiated steering action for steering the vehicle towards one side of the target; determining a degree of understeering of the host vehicle; when the degree of understeering exceeds a first understeering threshold, controlling a steering control system of the vehicle to counteract the user initiated steering action to thereby reduce the degree of understeering. The invention further relates to an evasive steering system.
