The invention relates to a collision risk assessment method based on a road environment and a vehicle system. According to one embodiment of the present invention, a method for evaluating collision risk based on a road environment comprises the steps of: estimating a road surface friction coefficient distribution using one or more sensors; a step of calculating a road environment-based expected deceleration amount distribution of the own vehicle using the estimated road surface friction coefficient distribution and an expected deceleration amount of the own vehicle; a step of calculating a front safe distance distribution between the own vehicle and the preceding vehicle using the calculated expected deceleration amount distribution of the own vehicle; and a step for calculating the degree of risk of a forward collision based on the current distance between the own vehicle and the preceding vehicle on the basis of the calculated forward safe distance distribution.

    本发明涉及一种基于道路环境的碰撞危险评估方法以及车辆系统。根据本发明的一实施例的基于道路环境的碰撞危险评估方法,包括:利用一个以上的传感器估算路面摩擦系数分布的步骤;利用所估算的路面摩擦系数分布和自身车辆的预期减速量来计算自身车辆的基于道路环境的预期减速量分布的步骤;利用计算出的自身车辆的预期减速量分布来计算自身车辆和前方车辆之间的前方安全距离分布的步骤;以及,以计算出的前方安全距离分布为基础,计算基于自身车辆和前方车辆之间的当前距离的前方碰撞危险度的步骤。
