The invention relates to a vehicle braking control method and device under the long downhill condition, and belongs to the technical field of vehicle control The vehicle braking control method under the long downhill condition comprises the steps that under the condition that a vehicle is located on a long downhill road section, the braking strength currently needed by the vehicle is determined based on the current vehicle speed, the current road gradient and the whole vehicle mass; the braking mode of the vehicle is determined based on the braking strength currently needed by the vehicle, and the braking mode is determined by braking power generated by the number of braking air cylinders; and the braking mode is adjusted based on the vehicle speed keeping condition and the air inlet temperature change condition of the vehicle. According to the invention, the vehicle speed stability control of the long downhill can be realized under the condition that a retarder is not arranged, and the cost of the whole vehicle is reduced while a certain braking power is ensured.
本发明涉及一种长下坡情况下的车辆制动控制方法及装置,属于车辆控制技术领域,其中,该长下坡情况下的车辆制动控制方法包括:在车辆处于长下坡路段的情况下,基于当前的车速、道路坡度及整车质量,确定车辆当前需求的制动强度;基于车辆当前需求的制动强度,确定车辆的制动模式,所述制动模式由制动气缸数所产生的制动功率确定;基于车辆的车速保持情况及进气温度变化情况,对所述制动模式进行调整。本发明能够在不设置缓速器的情况下实现长下坡的车速稳定控制,在保证一定制动功率的同时,降低了整车成本。
