Chris Schwarz, simulation software team leader and senior research engineer at the National Advanced Driving Simulator, has received a U.S. Patent for an application using digital map data to adapt the performance of electronic stability control in a vehicle, particularly on banked or sloped roads.
Schwarz and his collaborators developed the patented system to reduce vehicle lateral skidding. The system receives inputs from wheel speed sensors, a steering wheel position sensor, a yaw rate sensor, and a lateral acceleration sensor. It also receives information that indicates at least a property of the road where the vehicle is located through a map database.
The system then incorporates the road property information to determine when and how to modify how the vehicle acts to reduce skidding.
