What does autohold mean in a car?

[DiRachel]

Autohold in a car refers to the automatic parking system. The button for this function may be labeled as "autohold" or feature a semicircle with the letter "a" inside. Despite the different appearances, the buttons serve the same purpose. The automatic parking system is a technological application that enables the automatic handbrake function while the car is in motion. It allows drivers to avoid prolonged braking when the vehicle is stationary and prevents unnecessary sliding when the system is activated. The autohold function utilizes a slope sensor to provide precise parking force through the controller. During startup, the parking control unit calculates information from sensors such as 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, ensuring a smooth start for the vehicle.
