The invention provides a gear shifting optimization method and system based on a dual-motor multi-gear hybrid transmission architecture, and the method comprises the steps: recognizing a gear shifting demand, and obtaining a wheel side torque demand and a vehicle speed demand; acquiring vehicle driving information, and correcting a preset first condition and a preset second condition based on a correction strategy in combination with the vehicle driving information; and judging the wheel side torque demand and the vehicle speed demand, if the wheel side torque demand and the vehicle speed demand meet a first condition, adopting AMT gear shifting, and if the wheel side torque demand and the vehicle speed demand meet a second condition, adopting C2C gear shifting. According to the method, the optimal gear shifting strategy is intelligently selected according to the actual driving working condition, the driving smoothness and the dynamic response of the hybrid electric vehicle are improved, and an efficient and smooth gear shifting solution is provided for the hybrid electric vehicle.

    本发明提供了一种基于双电机多挡混动变速箱架构换挡优化的方法及系统,方法包含:识别换挡需求,并获取轮边扭矩需求与车速需求;获取车辆行驶信息,并基于修正策略结合所述车辆行驶信息对预设的第一条件、第二条件进行修正;判断所述轮边扭矩需求与车速需求,若符合第一条件则采用AMT换挡,若符合第二条件则采用C2C换挡。本发明根据实际驾驶工况智能选择最优换挡策略,提高了混合动力车辆的驾驶平顺性和动力响应,为混合动力汽车提供了一种高效、平顺的换挡解决方案。
