Title: POWER TRANSMISSION SYSTEM AND VEHICLE HAVING SAME
Abstract:
A power transmission system (1000) comprises: a power source (100); a gear shift unit (200) adapted to be selectively connected, by power coupling, to the power source (100); a first motor generator unit (300); a system power output section (401); a first model switching device (402), wherein at least one of the gear shift unit (200) and the first motor generator unit (300) is connected, by power coupling, to or disconnected from the system power output section (401) by means of the first model switching device (402); and a second model switching device (403), wherein the gear shift unit (200) may be connected, by power coupling, to or disconnected from the first model switching device (402) by means of the second model switching device (403), and the gear shift unit (200) may be connected, by power coupling, to the first model switching device (402) by means of the second model switching device (403), so as to output power from the power source (100) to the first model switching device (402) upon speed reduction by the gear shift unit (200) and second model switching device (403) in sequence. The power transmission system can enrich driving modes of a vehicle and enable the vehicle to adapt to different road conditions, so that driving experience of a driver can be improved. Also provided is a vehicle having the power transmission system.
