What does 'autoh' mean in BMW cars?

[Nina]

In BMW cars, 'autoh' refers to the automatic handbrake. The method to use the autoh function in BMW cars is: 1. Fasten the seat belt. 2. Press the autoh button after closing the door. 3. At this point, the BMW automatic parking system function can be activated. Additional information: Here is some introduction about the electronic handbrake: 1. The electronic handbrake is a technology that achieves parking braking through electronic control. Its working principle is the same as that of a mechanical handbrake, both of which control parking braking through the friction generated between the brake disc and the brake pads. 2. The electronic handbrake has evolved from the basic parking function to the automatic parking function AUTO-HOLD. The application of the AUTO-HOLD automatic parking function technology allows drivers to not need to brake for a long time when the vehicle stops. When the automatic electronic parking brake is activated, unnecessary sliding of the vehicle can be avoided.
