The invention provides a commercial vehicle safety following distance control method, which comprises the following steps of: detecting a vehicle load before and after the vehicle is started and stopped or when the vehicle moves at a constant speed, acquiring a vehicle load coefficient, and acquiring a road adhesion coefficient and a road gradient of the current driving road of the vehicle; according to the current load coefficient of the vehicle, the adhesion coefficient of the current driving road surface of the vehicle and the road gradient, calculating the vehicle safety following distance by combining the current speed of the vehicle; determining a car following danger level based on the size relationship between the distance between the current car and the front car and the safe car following distance; and formulating a corresponding active safety car following protection strategy according to the car following danger level. According to the method, the safe vehicle following distance is calculated according to the current driving road condition of the vehicle, various environmental factors and the like, the calculated safe vehicle following distance is not fixed and is more accurate, active safe vehicle following protection is carried out on the vehicle, and the problem that no active safety function exists or active safety measures are too single in the vehicle driving process is solved.
本发明提供一种商用车安全跟车距离控制方法,包括:在车辆启停前后或者车辆匀速运动时检测车辆载荷,获取车辆载荷系数,并获取车辆当前行驶的路面附着系数和道路坡度;根据车辆当前载荷系数、车辆当前行驶的路面附着系数和道路坡度,结合车辆当前车速计算车辆安全跟车距离;基于当前车辆与前车的距离与所述安全跟车距离的大小关系确定跟车危险等级;根据所述跟车危险等级制定相应的主动安全跟车保护策略。本发明根据车辆当前行驶的路况和各种环境因素等计算安全跟车距离,计算的安全跟车距离并不是固定不变的,会更加准确,以及对车辆进行主动安全跟车保护,解决车辆行驶中没有主动安全功能或者主动安全措施过于单一的问题。
