Do You Need to Press the Brake Pedal All the Way Down When Driving an Automatic Transmission Car?
1 Answers
When driving an automatic transmission car, you do not need to press the brake pedal all the way down. Here is some relevant information about braking in automatic transmission cars: 1. Introduction: (1) The gear shifting actions in an automatic transmission car are controlled by the TCU (Transmission Control Unit), and there is no need to press the brake pedal. In manual mode, the TCU performs gear shifts automatically based on the shift curve, while the driver determines the timing of the shift. (2) To prevent accidental shifting from P (Park) to D (Drive) or R (Reverse), automatic transmission vehicles are equipped with a shift lock function, which requires the brake pedal to be pressed before shifting from P to any other gear. 2. Precautions: Lightly pressing the brake pedal will prompt the computer to downshift automatically based on engine load and vehicle speed. It is not advisable to frequently or rapidly press the brake or accelerator pedal all the way down in an automatic transmission car. The automatic transmission relies on the engagement and disengagement of clutches and brakes for power transmission. Frequent rapid pressing or pressing all the way down can cause abrupt speed changes, leading to instant locking or incomplete disengagement of the brakes and clutches. This can result in severe wear and damage to the automatic transmission's mechanical components, as well as increase the temperature of the automatic transmission fluid (ATF), thereby shortening its service life.
