METHOD TO SHUT OFF ADAPTIVE CRUISE CONTROL WHEN THE UPHILL GRADIENT IS TOO STEEP

摘要

A method of controlling an adaptive cruise control (ACC) system of a vehicle. The method including: determining a torque of an engine of the vehicle, determining a torque of a transmission of the vehicle, calculating an idle force of the vehicle, obtaining a maximum tolerable gradient, obtaining an actual gradient of a surface the vehicle is on, and turning off the adaptive cruise control when the actual gradient exceeds the maximum tolerable gradient.
