The invention discloses a charging control method and system for an idling start-stop vehicle, and the method comprises the steps: charging a storage battery according to a charging strategy; a recording period is set, in the initial recording period, the target voltage corresponding to the maximum recording value in the recorded highest SOC values serves as the target voltage in the next vehicle driving period and is assigned to the short-term learning values, after the initial recording period is completed, the last short-term learning value is assigned to be a long-term learning value, and the corresponding SOC value is assigned to be a long-term pre-charging value; according to a comparison strategy, performing assignment iteration on the short-term learning value, the long-term pre-recharge value and the long-term learning value of the next recording period; by continuously correcting the SOC value and controlling the charging of the storage battery, the 12V storage battery can be fully charged, the aging of the storage battery caused by insufficient electricity is prevented, the vehicle is easy to enter a start-stop state in an idling and braking state, the generator can be immediately controlled to stop charging the storage battery after the storage battery is fully charged in a healthy state, the fuel oil is saved, and the emission is reduced.

    本发明公开了一种怠速启停车辆的充电控制方法及系统,其中,方法包括根据充电策略对蓄电池充电;设置记录周期,在初始记录周期,将已记录的最高SOC值中最大记录值相应的目标电压作为下一次车辆行驶期间的目标电压赋值给短期学习值,在完成初始记录周期后,取最后一个短期学习值赋值为长期学习值,其对应的SOC值赋值为长期预充值;根据比较策略,对下一个记录周期的短期学习值、长期预充值和长期学习值进行赋值迭代;本发明通过SOC值不断修正,进行蓄电池充电控制,可将12V蓄电池充足电,防止蓄电池亏电而老化,满足车辆在怠速、制动状态下容易进入启停状态,可在蓄电池健康状态充足电后,立即控制发电机停止为蓄电池充电,节省燃油,降低排放。
