What does manual-automatic integration mean?

[MacAlan]

Manual-automatic integration refers to a transmission method that combines both manual and automatic shifting systems in a car. Its characteristics include: 1. Effective braking: When the car needs to brake in an emergency, switching to manual mode allows the use of the car's transmission for gear reduction, achieving better deceleration; 2. Faster overtaking: By using the appropriate gear to instantly increase the engine speed, a car with manual-automatic integration can utilize manual mode for overtaking. The functions of the transmission are: 1. Changing the transmission ratio to expand the range of torque and speed variations of the driving wheels, adapting to frequently changing driving conditions and allowing the engine to operate under favorable conditions; 2. Enabling the car to reverse without changing the engine's rotation direction; 3. Using neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifting or power output.
