Cooperative Collision Avoidance by Sharing Vehicular Subsystem Data

Vehicular subsystems such as Anti-lock braking (ABS), Traction Control System (TCS) and Electronic Stability Program (ESP) use low-level sensory data to maintain the vehicle’s stability. We show that sharing that information with neighboring vehicles could prevent potential collisions. Towards achieving this goal, we propose extensions to Dedicated Short Range Communication (DSRC)’s Basic Safety Message (BSM) set and propose a controller which can use the transmitted information to avoid collisions with vehicles experiencing in-stabilities. We show the utility of our methodology by using 3 common lane change scenarios under varying road surface conditions. Finally, we demonstrate some limitations of our methodology using similar scenarios.
