The driver assistance uses the inputs to determining a lane change risk function based on the lane boundary position, a road boundary risk function based on the road boundary position, and a collision risk function based on the object position. The risk functions quantifying the risk posed to the vehicle by the detected hazards. Based on the risk functions, the driver assistance controls an actuator of the vehicle.
