The invention relates to a self-adaptive neutral gear sliding control method and device in a cruise state, and belongs to the technical field of auxiliary driving, and the self-adaptive neutral gear sliding control method in the cruise state comprises the steps that a plurality of downhill road sections meeting preset conditions in a map data coverage range are obtained; determining a target downhill road section to which the vehicle is about to arrive in the plurality of downhill road sections based on the current position of the vehicle; and based on the starting point position of the target downhill road section, the current vehicle speed, the cruising target vehicle speed, the cruising vehicle speed fluctuation lower limit and the vehicle running resistance, the starting point position of neutral-gear sliding of the vehicle is determined. According to the method, the complexity and the cost of neutral gear sliding control during cruising of the vehicle are reduced through simple and convenient control steps, the method can be suitable for a complex road with a plurality of downhill road sections, and the flexibility of a neutral gear sliding control strategy is improved.

    本发明涉及一种巡航状态下的自适应空挡滑行控制方法及装置,属于辅助驾驶技术领域,其中,该巡航状态下的自适应空挡滑行控制方法包括:获取地图数据覆盖范围内满足预设条件的多个下坡路段;基于车辆当前位置在所述多个下坡路段中确定车辆即将达到的目标下坡路段;基于目标下坡路段的起始点位置、车辆当前车速、巡航目标车速、巡航车速波动下限以及车辆运行阻力,确定车辆进行空挡滑行的起始点位置。本发明通过简便的控制步骤降低了车辆在巡航时进行空挡滑行控制的复杂度和成本,并且能够适用于存在多个下坡路段的复杂道路,提高了空挡滑行控制策略的灵活性。
