Abstract: This application discloses a hybrid power automobile and a power system thereof. The power system includes: an engine, where the engine outputs power to wheels of the hybrid power automobile through a clutch; a power motor, where the power motor is configured to output a drive force to the wheels of the hybrid power automobile; a power battery, where the power battery is configured to supply power to the power motor; a DC-DC converter; and an auxiliary motor connected to the engine, where the auxiliary motor is connected to the power motor, the DC-DC converter, and the power battery, and when performing power generation under driving of the engine, the auxiliary motor implements at least one of charging the power battery, supplying power to the power motor, and supplying power to the DC-DC converter. Therefore, low-speed electric balance and low-speed smoothness of the entire vehicle can be maintained.

Abstract: A thermal management system includes a heat pump, a battery waterway, a heat exchange waterway, a heat dissipator waterway, an electric assembly waterway, a first heat exchanger, and a control valve group. A first heat exchange path of the first heat exchanger is connected to the heat pump, and a second heat exchange path of the first heat exchanger is connected to the heat exchange waterway. The electric assembly waterway may be connected to the heat dissipator waterway or the heat exchange waterway in series. The battery waterway may be connected to the heat dissipator waterway or the heat exchange waterway in series. The battery waterway, the heat exchange waterway, the heat dissipator waterway, and the electric assembly waterway may be connected in series.

Abstract: A heat management system includes a first heat exchanger, a second heat exchanger, a heat pump, an electric assembly waterway, a radiator waterway, a battery waterway, and a heat exchange waterway. The heat pump module includes a first heat exchange pipeline and a second heat exchange pipeline. A first heat exchange passage and a second heat exchange passage of the first heat exchanger are respectively disposed on the second heat exchange pipeline and the heat exchange waterway. A third heat exchange passage of the second heat exchanger is disposed on the first heat exchange pipeline, and a fourth heat exchange passage of the second heat exchanger is in communication with the radiator waterway. The radiator waterway and the electric assembly waterway may be in communication in series.

Abstract: The speed control device is equipped with: an actual speed acquisition unit; an actual position acquisition unit; an acceleration/deceleration control unit; and a travel resistance calculation unit. When in a situation in which an target speed increases from a first target speed to a second target speed, the target speed in the second road section is set such that an actual speed increases with a first-order lag from the first target speed to the second target speed over a period between the start position and end position of the second road section, and the target speed in the second road section is set such that the amount of change in the speed, which increases with the first-order lag, with respect to the travel time of the vehicle is decreased as the travel resistance calculated by the travel resistance calculation unit increases.
