Weather-dependent driver assistance system

A control system for a vehicle, the control system comprising one or more controllers, wherein the control system is configured to:

• receive information indicative of a weather condition;
• in dependence on the information indicative of a weather condition, modify at least one spatial range parameter of a driver assistance system configured to monitor other road users, wherein the at least one spatial range parameter comprises a trigger range for triggering an action based on a detected range of another road user, wherein the driver assistance system comprises a blind spot monitoring function and the at least one spatial range parameter comprises an exit condition range for ending a blind spot monitoring action;
• and
• in dependence on the detected range of another road user, cause an actuator of the vehicle to perform an action comprising at least one of:
• a collision avoidance action;
• and a collision mitigation action, wherein the control system is configured to increase the trigger range in dependence on the information indicating an adverse weather condition, and not increase the trigger range in dependence on the information not indicating an adverse weather condition, wherein the driver assistance system comprises a pre-crash function,
• wherein the control system is configured, in dependence on the information indicating the adverse weather condition, to move the exit condition range to a point at which a rear of a passing road user no longer overlaps the vehicle when viewed in a lateral direction.

A method of controlling a driver assistance system of a vehicle, the method comprising:

• receiving information indicative of a weather condition;
• in dependence on the information indicative of a weather condition, modifying at least one spatial range parameter of a driver assistance system configured to monitor other road users, wherein the driver assistance system comprises a blind spot monitoring function;
• and
• in dependence on a detected range of another road user, cause an actuator of the vehicle to perform an action comprising at least one of:
• a collision avoidance action;
• and a collision mitigation action,
• wherein the at least one spatial range parameter comprises an exit condition range for ending a blind spot monitoring action, and
• wherein modifying said at least one spatial range parameter comprises, in dependence on the information indicating an adverse weather condition, moving the exit condition range to a point at which a rear of a passing road user no longer overlaps the vehicle when viewed in the lateral direction.
