Nonlinear dynamics of autonomous vehicles with limits on acceleration

Davis, L.C. - In: Physica A: Statistical Mechanics and its Applications 405 (2014) C, pp. 128-139

coefficient is equal to the headway time constant [k=1/h]. Furthermore, if the sensitivity α>1/h, no collisions occur. String … stability for small perturbations is assumed and the initial condition is taken as the equilibrium state. Other values of k and …

The effects of mechanical response on the dynamics and string stability of a platoon of adaptive cruise control vehicles

Davis, L.C. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 17, pp. 3798-3805

The dynamics of a platoon of adaptive cruise control vehicles is analyzed for a general mechanical response of the vehicle. Effects of acceleration-feedback control that were not previously studied are found. For small acceleration-feedback gain, which produces marginally string-stable behavior,...
