Both vehicle speed and road geometry are necessary in determining the vehicle's risky behavior. The traditional ACC vehicle regulates the speed considering instantaneous effects of road conditions, but ignoring the geometrical features of oncoming road and accompanied influence on the vehicle dynamics. So, vehicle accidents are likely to happen on these roads. To elaborate on a vehicle's speed on variable road geometry, the vehicle model is analyzed considering road geometry and whether the vehicle can regulate the speed fitting in with the variable road geometry to ensure the ride safety and comfort. Hence, we developed an intelligent speed adaption controller by using Terminal Sliding Mode Control method, which has a fast convergence and good tracking performance. The simulation results demonstrate the effectiveness and stability of the designed controller. The proposed approach can deal well with a combination of adaptive cruise control and intelligent speed adaption on variable road geometry.
