How to Decelerate an Automatic Transmission Car?

[VanDawson]

Methods to decelerate an automatic transmission car include: 1. Press the brake pedal to push hydraulic pressure, causing the brake caliper to press the brake pads against the brake disc, creating significant friction and generating braking force to slow down the car; 2. Release the accelerator pedal to reduce the engine's fuel supply, which naturally slows down the vehicle. The car will automatically select the appropriate gear based on the driving speed and traffic conditions. Automatic transmission cars have six gear positions, arranged from top to bottom as: P, R, N, D, S, L. An automatic transmission car uses an automatic transmission (AT) to regulate speed. While driving, the control system of the automatic transmission automatically selects the appropriate gear based on the engine's speed and load, replacing the driver's subjective judgment of timing and gear shifting operations.
