If you are a BMW user or would like to buy one, then you might have come across Auto H. But, what is Auto H on BMW? Auto H is the innovative BMW feature which enhances driver convenience when applying the parking brake automatically as soon as the vehicle stops. This function is known also as Auto Hold and prevents a car rolling backwards or ahead on inclines.
What does Auto H mean on a BMW?
Auto H represents Auto hold. This system helps drivers to maintain the car’s position at a stop, particularly on slopes and in traffic. As soon as the car stops, the system engages its parking brake, so the driver doesn’t have to press the pedal down or apply any manual brake.
This is a useful feature when you are required to stop briefly, for example at traffic signs or lights. Auto H will make driving easier as it prevents you from having to stop the car or hold down the pedal.
How Auto H on BMW works?
Auto Hold works by combining sensors, the brake system of the car, and an automatic transmission. This allows it to be determined when to release and apply parking brake. The following is the way it works.
- Auto H: is a function that automatically activates the parking braking system when a car comes to complete halt. This stops the car rolling backwards and forwards in a downward slope.
- Interactions with the Transmission System: When a driver releases the pedal of the brake, Auto H automatically brakes the car, stopping it without the requirement to manually engage the parking braking system.
- Drive Experience with Auto-H: Once the system is activated it will hold your car until you release the gas pedal. Once you move off the stop, Auto H releases the break.
