ACC in sedans stands for Adaptive Cruise Control. The functional components of ACC include: 1. Radar sensor; 2. Electronic control unit; 3. Cruise control switch; 4. Speed setter; 5. Distance setter; 6. Status display; 7. Alarm. The functions of ACC in sedans are: 1. Maintaining longitudinal vehicle movement, where the vehicle alerts the driver and performs active braking intervention in case of collision risks; 2. When the distance to the vehicle ahead is too small, the ACC control unit coordinates with the anti-lock braking system and engine control system to apply appropriate braking to the wheels, ensuring the vehicle always maintains a safe distance from the vehicle ahead.

A gear-driven transmission typically consists of a housing and several gear pairs. Function: During vehicle operation, to adapt to varying conditions, the driving force and speed of the car need to change within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the transmission is installed.
