Abstract
A system and method are provided for identifying a potential road hazard in a host vehicle based on a remote vehicle. The host vehicle has a host vehicle-to-vehicle (V2V) module and a host advanced driver assistant system (ADAS) module, such as a system employing the ADASIS standard. The remote vehicle also has a remote V2V module that provides position data, and one or more of, longitudinal acceleration data, steering angle change rate data, braking system data, anti-lock braking status and stability control system status of the remote vehicle. The host vehicle receives the position data of the remote vehicle using the host V2V module and determines if the remote vehicle is in the main path zone (MPZ) of the host vehicle. The system determines a potential road hazard when it receives a signal indicating any of the following are true, the longitudinal acceleration data and/or the steering angle change rate data of the remote vehicle exceeds a predetermined threshold, the anti-lock braking system of the remote vehicle is activated, or the stability control system of the remote vehicle is activated. The system indicates the potential road hazard to a driver of the host vehicle when a potential road hazard is identified and the remote vehicle is in the MPZ of the host vehicle.
