Modeling cooperative and autonomous adaptive cruise control dynamic responses using experimental data
Experimental data are used to derive models of ACC and CACC dynamic response. Simulation results show that simple ACC and CACC models match real behavior closely. ACC displays a lightly-damped second order response plus pure time delay. CACC displays a first-order lag response with a short time constant. Test results and simulations show the string instability of ACC and stability of CACC.
