Abstract
In an adaptive speed control system for a vehicle, a method and system are provided for controlling a speed of the vehicle while the vehicle is traversing a curved path. The method includes sensing a yaw rate of the vehicle, determining a yaw acceleration based on the yaw rate, and determining a maximum allowed speed of the vehicle on the curved path based on the yaw rate and the yaw acceleration, the maximum allowed speed being capable of varying continuously. The method also includes limiting the speed of the vehicle on the curved path to a value no greater than the maximum allowed vehicle speed. The system includes a sensor capable of sensing a yaw rate of the vehicle, and a controller capable of determining a yaw acceleration based on the yaw rate, and capable of determining a maximum allowed speed of the vehicle on the curved path based on the yaw rate and the yaw acceleration, the maximum allowed speed being capable of varying continuously. The controller of the system is also capable of limiting the speed of the vehicle on the curved path to a value no greater than the maximum allowed vehicle speed.
