AI Technical Summary
Technical Problem
Existing coasting energy recovery technology cannot adapt to complex driving conditions, cannot meet the driving needs of users, and is prone to battery overcharging.
Method used
Driving behavior factors are determined based on vehicle speed, throttle opening, and throttle opening change rate. The coasting energy recovery torque is adaptively adjusted by combining the remaining battery charge and road gradient, including the correction and compensation coefficient calculation of the basic coasting recovery torque.
Benefits of technology
It achieves adaptive adjustment of coasting energy recovery intensity to meet user driving needs, improve energy recovery efficiency, optimize driving experience, and extend battery life.

Abstract
本发明涉及一种自适应调节的滑行能量回收控制方法及系统，属于车辆滑行能量回收技术领域，解决了现有技术对工况适应性差、无法满足用户的驾驶需求的问题。本发明的方法包括：根据车辆的行驶速度、油门开度和油门开度变化率确定驾驶行为因子；根据驾驶行为因子和车辆的行驶速度、油门开度以及制动踏板开度判断车辆是否进入滑行工况；若车辆进入滑行工况，则根据行驶车速确定基础滑行回收扭矩，根据电池剩余电量确定电量补偿系数，以及根据道路坡度确定坡度补偿系数；根据驾驶行为因子、电量补偿系数和坡度补偿系数对基础滑行回收扭矩进行修正以获得最终滑行回收扭矩。实现了不同工况下的滑行回收扭矩自适应调节，优化了驾驶体验。
