REAL TIME RISK ASSESSMENTS USING RISK FUNCTIONS

摘要

A driver assistance system takes as input a number of different types of vehicle environment inputs including positions of hazards such as a road boundary, lane boundaries, and objects in the vehicle's environment. 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. This may include control of actuators such as the steering wheel, brake system, and gas, as well as audio and visual display and warning systems.
