What does brakehold mean on a car?

Brakehold on a car refers to an automatic parking function. After activating this function, it can simplify operations by avoiding the use of the handbrake or electronic handbrake, eliminating the need for frequent shifting between D to N or D to P in automatic transmission models. The function and working principle of automatic parking are as follows: Function of automatic parking: The vehicle will not roll, making it suitable for uphill or downhill driving or frequent starts and stops. Working principle of automatic parking: Through the slope sensor, the controller provides accurate parking force. When starting, the parking control unit calculates information provided by 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, allowing the car to start smoothly.
Speaking of brake hold, as a commuter who often drives in the city, I find this feature to be a lifesaver in urban traffic congestion. It's essentially an automatic parking system that maintains brake pressure after you come to a complete stop and release the brake pedal, preventing the vehicle from rolling backward. It's particularly useful when stopping at red lights on hills or during temporary stops, eliminating the need to engage the handbrake or keep your foot on the brake pedal—saving effort while enhancing safety. It's my favorite feature when driving an automatic transmission car, and activation is simple—just press the brake hold button on the center console. When the light turns green, simply press the accelerator to move. This feature also helps extend the lifespan of the handbrake. However, I'd like to remind everyone that on slippery roads or steep slopes, it's best to double-check if the system has engaged successfully to avoid any unintended rolling.
Having driven for over a decade, I've experienced many heart-stopping moments of vehicle rollback. Brake hold has now become one of my most relied-upon safety features. Its core function is to prevent automatic rolling after stopping, utilizing the vehicle's electronic braking system to lock the wheels. For instance, when queuing on a slope in a supermarket parking lot, the car stays firmly in place the moment I release my foot from the brake, saving me from the distraction of operating manual devices. The benefits include reducing the risk of fatigued driving and working in tandem with auto start-stop to save fuel. However, a small tip: this feature might not come standard on older models and may require an optional package. When using it, pay attention to whether the vehicle's dashboard indicator lights up normally to avoid potential malfunctions causing trouble.
I usually drive my kids to and from school, so I pay attention to the practicality and convenience of small car features. The brake hold function makes driving much easier—it automatically holds the brakes when you stop, preventing the car from rolling. At the crowded school gate, once parked, I can release my foot, and the car stays firmly in place. When the kids get in, I just press the accelerator to start, without the hassle of pulling the handbrake. It's a thoughtful feature for new moms, reducing the stress of starting on a slope. Just remember to keep it clean and avoid letting debris block the button.
