The invention discloses a sliding deceleration control method, equipment, a storage medium and a device. The sliding deceleration control method comprises the following steps: determining a sliding deceleration required torque required by a current sliding speed according to current sliding working condition information of a to-be-controlled vehicle; determining generated power generated by the to-be-controlled vehicle during sliding according to the sliding deceleration torque; judging whether the generated power is greater than the recoverable power corresponding to the second motor, and obtaining a judgment result; and according to the judgment result, the first motor is controlled to drag the engine to rotate so as to consume power, so that sliding speed reduction control over the vehicle to be controlled can be completed, the engine is used for outputting dragging resistance through in-cylinder control, and the first motor drives the engine to rotate so as to consume power. Compared with the prior art that when an energy storage system of a hybrid electric vehicle does not have the capacity of supporting sliding speed reduction, the sliding speed reduction feeling under the high-speed sliding working condition cannot be maintained, and the safety under the mountain road long downhill working condition cannot be improved, the sliding speed reduction feeling is maintained, and the energy storage system cannot be overcharged.

    本发明公开了一种滑行减速控制方法、设备、存储介质及装置,本发明通过根据待控制车辆的当前滑行工况信息确定当前滑行速度所需的滑行减速需求扭矩;根据滑行减速扭矩确定待控制车辆在滑行时产生的发电功率;判断发电功率是否大于第二电机对应的可回收功率,获得判断结果;根据判断结果控制第一电机拖动发动机转动进行耗电,以完成对待控制车辆的滑行减速控制,本发明使用发动机通过缸内控制,输出拖拽阻力,通过第一电机带动发动机转动消耗电量,相较于现有技术中在混合动力汽车储能系统没有可支持滑行减速的能力时,无法维持高速滑行工况下的滑行减速感并提高山路长下坡工况下的安全性,本发明维持了滑行减速感,也不会造成储能系统过充。
