How Does the Engine Start-Stop System Work?
1 Answers
The working principle of the engine start-stop system: When the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. At this point, the start-stop system automatically checks: the engine is idling and in neutral, the wheel speed sensor of the anti-lock system shows zero, and the electronic battery sensor indicates sufficient energy for a restart. Once these three conditions are met, the engine automatically stops running. How to use the engine start-stop system: Simply press the brake pedal while driving, and after the vehicle comes to a complete stop for about two seconds, the engine will automatically shut off. As long as the brake pedal is held down, the engine remains off. Releasing the brake pedal or turning the steering wheel will immediately trigger the engine to restart automatically, allowing the driver to press the accelerator and start moving again—all while remaining in Drive (D) mode.
