A New Model of Stopping Sight Distance of Curve Braking Based on Vehicle Dynamics
Discrete Dynamics in Nature and Society, 2016 Compared with straight-line braking, cornering brake has longer braking distance and poorer stability. Therefore, drivers are more prone to making mistakes. The braking process and the dynamics of vehicles in emergency situations on curves were analyzed.
