The invention relates to a method for predicting maintenance/replacement period for a component of a vehicle, the vehicle comprising a power-assisted steering system including a steering actuator () configured to assist in steering the vehicle at least as compensation for angular deviations of the road wheels () caused by road disturbances. The method comprises acquiring over time steering output data indicative of a magnitude and/or frequency of assisted steering as compensation for angular deviations of the road wheels () caused by road disturbances, comparing the acquired steering output data with stored component wear data, the stored component wear data being indicative of when maintenance/replacement of the component is due based on wear caused by road disturbances, and determining, based on the comparison of the acquired steering output data and the stored component wear data, whether or not maintenance/replacement of the component is due. The invention also relates to a system ().

Method and a system for predicting maintenance/replacement period for a component of a vehicle

A method for controlling a vehicle brake system for a heavy duty vehicle including a primary brake system and an auxiliary brake system. The method includes configuring a wheel slip magnitude limit, obtaining a requested auxiliary brake torque, engaging the primary brake system at a torque determined in dependence of the requested auxiliary brake torque, while monitoring a wheel slip value, determining an allowable auxiliary brake torque in dependence of the requested auxiliary brake torque and the wheel slip value, and engaging the auxiliary brake system at the allowable auxiliary brake torque.

Method for controlling auxiliary braking by a vehicle

The present disclosure relates to a method for controlling a steering assist system of a vehicle. Based on a signal indicative of a road characteristics of a road segment, a flow of fluid supplied by a fluid pump is controlled to generate a steering assist force to a wheel of the vehicle.

Method for controlling a steering assist system of a vehicle

The invention relates to a method of controlling steering of a vehicle (), comprising the steps of: acquiring (S) a signal indicative of a driver request indicative of a desired wheel angle of a turnable vehicle wheel (); determining (S), based on the signal indicative of the driver request, a control signal for an actuator () coupled to the turnable vehicle wheel to achieve the desired wheel angle; controlling (S) the actuator () using the control signal; detecting (S) an abrupt wheel disturbance event; and in response to detecting the abrupt wheel disturbance event: acquiring (S), from a lane detecting arrangement (), a signal indicative of a lane curvature ahead of the vehicle (); and controlling (S) the actuator () based on the lane curvature ahead of the vehicle ().
