The invention discloses an auxiliary braking control method, device and equipment and a storage medium, and relates to the technical field of vehicles, and the auxiliary braking control method comprises the steps that when the current braking state is a constant-speed braking state and the whole vehicle working condition parameters meet the constant-speed braking condition, the target speed difference is determined according to the target braking vehicle speed and the current driving speed; a target speed regulation torque is obtained according to the target speed difference, the current vehicle load, the current vehicle slope and a preset mapping relation; and performing auxiliary braking control on the vehicle according to the target speed regulation torque. Different braking torques are adaptively adjusted according to different load slopes, under the condition that the set vehicle speed is reached, the braking torque gradually approaches 0, the vehicle speed is kept constant, the continuous and effective braking effect can be guaranteed without operation of a driver, the auxiliary braking torque is adaptively adjusted, the auxiliary braking control method adapts to the full-slope and full-load working condition, and the driving safety is improved. The problem that the auxiliary braking torque is too large or too small and cannot be adjusted is solved.
本申请公开了一种辅助制动控制方法、装置、设备及存储介质,涉及车辆技术领域,所述辅助制动控制方法包括:在当前制动状态为恒速制动状态且整车工况参数满足恒速制动条件时,根据目标制动车速和当前行驶速度确定目标速度差;根据所述目标速度差、当前车辆载重、当前车辆坡度以及预设映射关系得到目标调速扭矩;根据所述目标调速扭矩对车辆进行辅助制动控制。通过根据不同载重坡度自适应调节不同制动扭矩,在达到设定车速情况下,制动扭矩逐渐趋近0,保持车辆恒速,无需驾驶员操作可保证制动效果持续有效,辅助制动扭矩适应性调节,实现了辅助制动控制方法适应全坡度全载荷工况,避免了辅助制动扭矩过大过小无法调节问题。
