摘要： A side rearview mirror control system for a vehicle that automatically changes a rear viewing angle of a side rearview mirror. The control system receives various vehicle inputs to determine if and when a vehicle operator will turn the vehicle, make a lane change, merge into a lane of traffic, etc. The system pivots the mirror to eliminate a potential blind spot during these conditions. In one embodiment, the rear view mirror control system receives input signals from a vehicle hand-wheel angle sensor, a vehicle yaw rate sensor, a vehicle speed sensor, a turn signal indicator, a global positioning system (GPS) receiver and map information to determine whether the vehicle is turning or will be turning.

摘要： A method is provided for determining an adhesive condition of a surface of a vehicle road using a statistical pattern recognition technique. A plurality of probability distribution functions is provided representing respective adhesive effects between the vehicle tire of a driven vehicle and the vehicle road. An index is calculated which represents a vehicle understeer characteristic. Probability analysis is applied for each of the road surface adhesive conditions as a function of the index. Each probability analysis is recursively updated. A likelihood factor is determined for each road surface adhesive condition as a function of each respective recursively updated probability analysis. Each respective road surface adhesive condition has a respective likelihood factor that identifies the likelihood of the road surface having the respective adhesive condition as a function of the index. The identified adhesive condition of the road surface is input into a vehicle control process.

摘要： A system and method for detecting a road curve as a vehicle approaches the curve, automatically providing road curvature information and controlling vehicle speed. The system uses a locating device and a map database to know the vehicle's position. Depending on the speed of the vehicle, the system generates a curvature profile for different curvature data points at or around the curve in front of the vehicle. The system then generates a desired speed profile for the curvature points. The desired speed profile and the actual vehicle speed are compared to determine whether the vehicle is traveling too fast for the target speed at each profile point. The acceleration computation can be enhanced by providing a driver cornering mode input that the vehicle operator can select based on how aggressively the driver wants the system to act to slow down the vehicle.
