The invention provides a retarding control method, device and equipment and a readable storage medium, and the retarding control method comprises the steps: taking the control of the constant speed of a vehicle as a target, carrying out the retarding control through the reverse sliding feedback torque generated by the reverse dragging of a motor under the permissible condition of a battery, and when the maximum sliding feedback torque allowed by the battery or the maximum sliding feedback torque limited by the highest gear of the whole vehicle cannot be effectively subjected to retarding control, in-cylinder braking is started, and the retarding control is assisted by the reverse braking torque applied by the engine. According to the invention, the situation of brake failure caused by overheat of a brake pad due to long-term intervention of mechanical brake during retarding control of the vehicle can be avoided; meanwhile, energy generated by overcoming gravitational acceleration can be recycled based on multi-gear sliding feedback, so that energy consumption during vehicle retarding control is reduced; and when the electric quantity of the battery is high, in-cylinder braking is started to provide larger braking force, and the defect caused by the fact that the vehicle cannot adopt auxiliary braking is overcome.
本发明提供一种缓速控制方法、装置、设备及可读存储介质,缓速控制方法包括:以控制车辆恒速为目标,首先在电池允许的情况下,通过电机反拖产生的反向的滑行回馈扭矩来进行缓速控制,当电池所允许的最大滑行回馈扭矩或者整车最高档所限制的最大滑行回馈扭矩不能有效进行缓速控制,则启动缸内制动,通过发动机施加的反向的制动扭矩来辅助进行缓速控制。通过本发明可以避免车辆在进行缓速控制时机械制动长期介入使刹车片过热,导致制动失效的情况出现;同时基于多挡位的滑行回馈可以回收克服重力加速度产生的能量,从而降低车辆缓速控制时的能耗;以及在电池电量较高时,启动缸内制动提供更大的制动力,弥补车辆因无法采用辅助制动带来的缺陷。
