What does the 'Please depress the brake pedal' prompt mean?

If the vehicle displays a 'Please depress the brake pedal' prompt, it serves as a reminder that the brake pedal must be pressed before the gear lever can be shifted to engage other gears. This design is actually intended to prevent driver misoperation and accidental gear shifts. The brake pedal is the pedal for vehicle braking, used to reduce or stop the speed of operating electric vehicles or mechanical equipment. The principle of the braking system is to fix the wheel or brake disc on the high-speed shaft of the equipment, install corresponding braking systems on the equipment base, and generate axial force under external force to achieve the braking effect. It is an essential and error-free system for vehicles. The composition of the vehicle braking system is as follows: Brake pedal: The pedal assembly acts as a lever. When the brake pedal is depressed, it applies force to the master cylinder piston. The pedal is located in the cabin and is simple to operate. Brake master cylinder: The brake master cylinder is a hydraulic pump that generates the pressure required for braking, distributing the pressure to the four-wheel slave cylinders through the master cylinder. Brake lines: To accommodate the vehicle's design, brake lines vary widely, including rubber hoses and metal pipes, primarily used to deliver brake fluid. Brake load-sensing proportioning valve; Brake booster; Brake slave cylinder; Brake pads, etc.
Last time when I started my car, the dashboard suddenly displayed a prompt saying 'Please press the brake pedal.' At first, I thought the car was broken, but then I remembered that automatic transmission vehicles require pressing the brake to start or shift gears. This is a safety design to prevent the car from rolling or accidentally starting when it shouldn't, especially on slopes. Once you press the brake, the system detects the brake signal and confirms it's safe before proceeding. I've also encountered situations where the prompt was flashing even though I had already pressed the brake. Later, I found out it was due to a loose brake pedal sensor causing a false alarm. After spending a bit of money to fix it, everything returned to normal. It's important to develop the habit of pressing the brake before starting the car. Simply put, this prompt is a reminder to protect yourself and others—don't ignore it.
