How to Distinguish Between the Brake and Accelerator Pedals in an Automatic Transmission Car?

[Gandalf]

In automatic transmission models, located below the driver's seat and the console from left to right are the brake pedal and the accelerator pedal, both controlled solely by the right foot. The gear shift is positioned to the right side in front of the center armrest. This design primarily aims to place the more frequently used accelerator pedal on the outer side of the right foot, which is a more comfortable posture for the human body. The brake pedal is set on the inner side of the right foot and is slightly higher than the accelerator pedal. The accelerator and brake pedals are the most commonly used pedals when driving a car. The accelerator pedal does not directly control the fuel injection volume. Instead, it controls the throttle valve's opening. Pressing the accelerator pedal increases the throttle valve's opening. At this point, the ECU, upon detecting more air entering the engine, instructs the fuel injection system to inject more fuel. A vacuum booster pump is connected behind the brake pedal. When the brake pedal is pressed, the vacuum booster pump provides assistance, making it easier for the driver to depress the brake pedal. When the brake pedal is pressed, the master cylinder pushes the slave cylinder through the brake fluid. The slave cylinder's piston then presses the brake pads against the brake disc, converting kinetic energy into heat energy and slowing down the car. Brake fluid needs to be replaced periodically as it is prone to absorbing moisture. Excessive water content in the brake fluid can reduce braking force and extend the braking distance.
