What does the brake hold system mean?
3 Answers
Brake hold system is the auto hold function. The following is a detailed introduction to the advantages and disadvantages of the auto hold function: 1. Advantages: (1) Prevents rolling: In situations requiring short stops such as traffic lights, the system will automatically brake the wheels after the vehicle comes to a stop to prevent rolling; when starting on an uphill slope, the system will automatically brake to prevent rolling back, and will release the wheels automatically after starting to allow direct forward movement. (2) Auto-lock: There is no need to pull the handbrake when parking and locking, as the system will automatically brake the wheels, but this is only available on some models. 2. Disadvantages: (1) Unable to lift the brake: If the auto hold function remains enabled during reversing, it is not possible to control the vehicle's slow movement by lifting the brake, and accidents may occur if the throttle is not well controlled. (2) Jerky feeling: Early versions of the auto hold function had a noticeable jerky feeling during use, resulting in a poor experience.
I've been driving for over a decade, and honestly, the brake hold system is a real game-changer. Simply put, when I'm stopped at a red light or stuck on a slope, the system automatically holds the brakes for me, so I don't have to keep my foot on the pedal. For example, when stopped on a steep slope, pressing the brake pedal a bit deeper activates it, with an indicator light on the dashboard to remind me; it automatically releases when I accelerate, preventing the car from rolling back. This feature is especially useful in city traffic or on hilly roads, reducing foot fatigue and allowing for more focused and safer driving. Nowadays, many automatic transmission cars come with it as standard, turned on by default every time you start the car, and it's super easy to use. I've also noticed it works well with the auto start-stop system—when stopped, the engine shuts off while the brakes stay engaged, saving fuel and hassle, making long red lights much more bearable.
As a tech-savvy car enthusiast who loves tinkering with vehicles, the brake hold system is actually pretty cool. It's not some high-end gadget—it simply uses electronic control to maintain brake pressure after detecting a complete stop, preventing the car from rolling. For example, when stopped at intersections or hilltops, the brake system sensors trigger the computer to lock the wheels in place; pressing the accelerator automatically releases it. Unlike electronic parking brakes, this is a temporary feature that doesn't affect gear shifting. Many new cars come equipped with this—I've used it multiple times in my family car, and operation is dead simple: just press the brake pedal firmly when stopped. An added benefit is reduced transmission wear, especially making automatic transmission starts smoother. I've tested it on steep climbs—total peace of mind.
