Parallel device drives the car together

The engine and the electric motor of the parallel device drive the car together. The engine and the electric motor belong to two systems, which can independently provide torque to the car driveline, and can be driven together or independently on different roads. When the car accelerates uphill, the motor and engine can provide power to the transmission mechanism at the same time. Once the car speed reaches the cruising speed, the car will only rely on the engine to maintain that speed. The electric motor can be used as a motor and a generator, also known as a motor-generator set. Since there is no separate generator, the engine can directly drive the wheels through the transmission mechanism. This kind of device is closer to the traditional automobile drive system, and its mechanical efficiency loss is similar to that of an ordinary automobile, and it is widely used.
