What does AUTOHOLD mean in cars?
1 Answers
Automotive AUTOHOLD refers to the vehicle's intelligent electronic parking brake, which is a function of the braking system. It automatically engages the parking brake after the vehicle stops to ensure safety, and lightly pressing the accelerator will automatically release the parking brake effect. The function of AUTOHOLD is to prevent the vehicle from rolling, making it suitable for uphill, downhill, or frequent starting and stopping situations. The working principle of AUTOHOLD is: the controller provides precise parking force through the slope sensor. When starting, the parking control unit calculates information provided by the clutch distance sensor, clutch engagement speed sensor, and accelerator pedal sensor. When the driving force exceeds the driving resistance, it automatically releases the parking brake, allowing the car to start smoothly.
