The invention relates to the technical field of vehicle control, and discloses a low-temperature starting method, device and equipment for an extended-range hybrid vehicle, and the method comprises the following steps: controlling an engine to operate at preset power; judging whether the temperature of the engine reaches the lowest temperature when the engine is allowed to operate at the maximum power or not; if yes, the power battery is controlled to be heated, and the power of the range extender is controlled to be within the preset interval; whether the temperature of the power battery reaches the lowest temperature when the whole vehicle can be driven or not is judged; and if yes, the output power of a range extender and the driving power of the whole vehicle are controlled, so that the power battery is kept in the preset discharging current interval for discharging till the power battery reaches the lowest temperature when the maximum discharging power is reached. According to the invention, the extended-range hybrid vehicle can be quickly started to enter an operable state in a low-temperature environment.
本发明涉及车辆控制技术领域,公开了一种增程式混合动力车辆的低温启动方法、装置及设备,该方法包括:控制发动机以预设功率运行;判断发动机的温度是否达到发动机允许最大功率运行时的最低温度;若达到,则控制对动力电池加热,并控制增程器功率在预设区间内;判断所述动力电池的温度是否已达到整车可驱动时的最低温度;若达到,则控制增程器输出功率与整车驱动功率,使所述动力电池保持在预设放电电流区间内进行放电,直至所述动力电池达到最大放电功率时的最低温度。本发明能够使得增程式混合动力车辆在低温环境下快速启动进入可运行状态。
