The invention relates to a hybrid vehicle, a drive control system, and a method for controlling a hybrid vehicle. The hybrid vehicle includes: an engine; a battery; a power converter; a relay; a first controller; and a second controller. The second controller is configured to control the engine and the power converter according to allowable charging power and allowable discharging power received from the first controller. The second controller has, as control modes, a normal mode in which the relay is closed and the battery and the power converter are electrically connected and a batteryless drive mode in which the relay is opened to cause the hybrid vehicle to move with the battery electrically disconnected from the power converter. The second controller is configured to select the batteryless drive mode when at least one of the magnitude of the allowable charging power and the magnitude of the allowable discharging power become smaller than a first predetermined value.
本发明涉及混合动力车辆、行驶控制系统和控制混合动力车辆的方法。一种混合动力车辆包括:发动机;电池;电力转换器;继电器;第一控制器;和第二控制器。第二控制器被配置为根据从第一控制器接收的可容许充电电力和可容许放电电力来控制发动机和电力转换器。作为控制模式,第二控制器具有其中继电器闭合并且电池和电力转换器被电气地连接的正常模式,和其中继电器断开以使混合动力车辆在电池从电力转换器电气地断连的情况下移动的无电池行驶模式。第二控制器被配置为当可容许充电电力的大小和可容许放电电力的大小中的至少一个变得小于第一预定值时选择无电池行驶模式。
