Abstract: In consideration of the extended reaction time of the elderly drivers and the relatively limited deceleration capability of elderly passenger cars, an anti-collision model of pure electric passenger vehicles for the elderly is developed by extending warning lead times, configuring warning, comfortable braking, and emergency braking scenarios. Through MATLAB simulation, it is observed that the stopping distance on wet roads exceeded that on dry surfaces, with the disparity growing alongside the trailing vehicle's speed; as the velocity differential between two vehicles increased, so do the variance in emergency braking distances on inclines, particularly evident on moist roads. When maintaining a constant speed differential, discrepancies in warning braking distances during curves became more pronounced as following car speeds escalated necessitating distinct curvewarning configurations.
