Abstract: A method for assisting a driver of a vehicle during operation in order to avoid an undesired situation based on a current driving scenario includes predicting if a first guiding force to a vehicle steering device is desired in order to avoid the undesired situation and, if the first guiding force is desired, predicting a total guiding force comprising the first guiding force, which would be applied to the steering device for avoiding the undesired situation, comparing the predicted total guiding force with a limit value, and if the predicted total guiding force exceeds the limit value, in advance, deciding whether to apply the predicted total guiding force to the steering device for avoiding the undesired situation or not.

Abstract: A method is provided for assisting a driver of a vehicle during operation by providing the driver with a desired steering feel. The method includes determining a desired steering device guiding force including a part representing a desired friction in a steering arrangement, and providing the driver with the desired steering feel based on the determined steering device guiding force.

Abstract: A method for changing a vehicle's trajectory, wherein the vehicle includes a steering arrangement including a manual steering device, at least one pair of ground engaging members and a mechanical interconnection therebetween, includes the steps of applying a braking force to at least one of the ground engaging members so that the vehicle's trajectory is changed, and simultaneously suppressing steering device disturbances resulting from the mechanical interconnection.

Abstract: A method for collision avoidance for a host vehicle includes the following steps; receiving input data relating to a set of objects external to the host vehicle, wherein an object position (r,?), and an object velocity ({dot over (r)}) are associated with each object by a sensor system arranged on the host vehicle, then estimating future trajectories of each external object, while considering influence by the future trajectories of the other external objects.

Abstract: A system for collision course prediction includes a host vehicle sensor system detecting information relating to a target object including a position and a velocity relative to the host vehicle; a time-to-collision estimator control block calculating an estimated time-to-collision based on a longitudinal distance, longitudinal velocity and longitudinal acceleration of the target object relative to the host vehicle; a lateral distance estimator control block, which estimates the lateral distance between the centers of the host vehicle and target object at the estimated time-to-collision; and a collision course condition determination unit determining, at a determination instant prior to the estimated time-to-collision, a probability that the host vehicle will collide with the target object dependent at least in part upon whether the lateral distance is within a first interval, the first interval based on at least a lateral width of the host vehicle and a lateral width of the target object.

Abstract: The invention generally relates to an improvement of conventional Hydraulically Power Assisted Steering system (HPAS-system) arranged to supply a steering assist force to the steering assembly of a vehicle as a response to a torque applied by a driver to the steering wheel. In such HPAS-systems a certain drivers torque always results in a certain assist force. The invention therefore discloses a valve that can be actuated to dynamically alter the steering assist force produced by the HPAS-system. This makes it possible to dynamically adjust the assist force so that an appropriate force may be delivered to fit the specific driving scenario.

Abstract: A steering system and control system for controlling an assist force imposed to the steering assembly of a vehicle, so as to deliver a steering wheel resist torque that can be felt by the vehicle driver and a method for the same, wherein the actual steering wheel resist torque is compared with a desired steering wheel resist torque, whereupon the actual steering wheel resist torque is adapted to be substantially the same as the desired steering wheel resist torque through adapting the amount of said assist force.
