Toward a Methodology to Assess Safety of a Vehicle

Technologies for route planning, automated vehicle localization, and real-time vehicle monitoring (maintenance indicators, consumption, etc.) have been developed, as well as tools for reducing the fuel consumption and gas emission. Transport companies and insurance companies use vehicle sensors for monitoring the speed, driving time, and other variables (hard braking, lateral acceleration, etc.), but these are insufficient for indicating the safety margin under all operating conditions. For example, when driving in a curve, the safety margin will be more or less away from the vehicle yaw limits depending on several factors like the speed, the mass distribution or the road friction coefficient, which can change abruptly. Herein, the authors propose a methodology and define an objective metric for monitoring the safety level during driving, providing a tool for driver evaluation from a safety standpoint. The methodology evaluates the driver behavior during driving and is based on the fundamentals of the safety controls implemented in existing vehicles. This methodology can be applied to classify the driver skills and reduced the crashes between vehicles, even, avoid hazardous situations by the interaction between vehicle and environment, thus improved the road safety.
