Engine starting phase
When the vehicle starts, only the motor drives it. The engine remains stopped. When it is necessary to increase the driving force, the motor (as an electric motor) starts the engine. The engine starting control sequence is: the ignition switch is on, the fuel pump runs when the driving force needs to be increased, and the high-voltage battery makes the motor open and increases the speed through the motor controller.
Starting and driving at low speeds (EV mode)
On the plug-in hybrid system, if the speed is less than 10 Km/h, the engine will stop running.
Speed up (Mixed mode)
When the accelerator pedal is completely pressed, the engine and motor clutch are closed, and the fuel pump and high-voltage battery are used as the power source, and the engine and motor drive the hybrid vehicle together.
High Speed Travel Control (Engine mode)
When traveling at high speeds, a plug-in hybrid vehicle is driven by the engine alone, with the motor in generator mode, similar to a conventional vehicle drive. The high voltage battery and the vehicle battery are charging at the same time.
D-stop or brake deceleration skid control
When a plug-in hybrid vehicle decelerates in D-gear or braking, the engine clutch opens, the engine shuts off, and the motor energy is recovered.
Charge control during parking
Both the engine and the motor stop working, and when the READY indicator is on and the vehicle is in P gear or reverse, the engine can be started smoothly if the monitoring item meets the conditions.
