What is the function of anti-rollback in cars?

[StephanieDella]

Automotive anti-rollback function refers to the Auto Hold system. The Auto Hold system is a technological application that enables automatic handbrake functionality during vehicle operation. This technology allows drivers to avoid prolonged braking when the vehicle comes to a stop, and prevents unnecessary vehicle slippage when the automatic electronic parking brake is engaged. How to use Auto Hold: Fasten your seatbelt, activate the auto function while driving. When the vehicle comes to a complete stop, you can release the brake pedal - a parking indicator will appear on the dashboard, and the vehicle will remain stationary while the gear can stay in D or N position. Gently press the accelerator to release the brake. Remember to shift to P gear and engage the handbrake when exiting the vehicle. Auto Hold principle: Radar sensors distributed around the vehicle measure distances and angles between the car and surrounding objects. The onboard computer then calculates operational procedures to adjust steering wheel rotation in coordination with vehicle speed, requiring the driver to only control the speed.
