What Does Auto Hold Mean?
2 Answers
Auto Hold refers to an automatic braking function. After activating this feature, it simplifies operations by eliminating the need to use the handbrake or electronic parking brake. For automatic transmission models, there's no need to frequently switch between D to N or D to P. The purpose of Auto Hold is to prevent the vehicle from rolling, making it suitable for uphill or downhill driving or frequent starts and stops. The working principle of Auto Hold is as follows: The controller provides precise parking force through a slope sensor. During startup, the parking control unit calculates information from the clutch distance sensor, clutch engagement speed sensor, and throttle pedal sensor. When the driving force exceeds the running resistance, the parking brake is automatically released, allowing the car to start smoothly.
Auto Hold is an incredibly practical feature in cars, primarily used in urban traffic jams or when parking to keep the vehicle in a braked state automatically, preventing it from rolling on slopes or at traffic lights. I remember when driving my car, this system is triggered automatically via electronic sensors detecting the wheels' stopped state—after releasing the foot brake, the car remains firmly in place until the accelerator is pressed. Compared to traditional manual handbrakes, it's effortless and smart, especially during peak congestion; I no longer need to keep my foot on the brake, giving it a rest. This feature is often integrated into the electronic parking brake system, with simple operation—just a button switch. The real benefit is enhanced driving convenience and safety. For instance, I frequently drive on mountain roads and never worry about rolling backward when starting on a slope. If you drive a new car, try this setting—you might fall in love with its lazy convenience.
