How to use the brake assist function?
3 Answers
Brake assist function is used as follows: 1. It can prevent wheel lock-up when braking. During vehicle braking, axial load transfer occurs, automatically adjusting the front and rear axle braking power distribution ratio to improve braking efficiency. It judges the driver's braking action and increases braking force during emergency braking to shorten stopping distance. 2. When the vehicle experiences wheel slip, tilt, or loss of tire grip torque, it purposefully controls individual wheel braking while reducing engine speed, ultimately bringing the vehicle back to normal driving trajectory to avoid dangers caused by loss of control. 3. By controlling the magnitude of driving force, it reduces the slip rate of drive wheel tires, prevents bumping, and helps stabilize the vehicle.
The brake assist system is actually quite straightforward to use, with no complicated steps. During normal driving, when you need to brake, just press the brake pedal as usual. However, the key point is in emergency situations—like when an obstacle suddenly appears—you should immediately stomp hard on the brake pedal without hesitation. The system will detect the forceful press via sensors and automatically amplify the braking force to help you stop faster. Not all cars activate this feature the same way; some high-end models may integrate radar to assess front and rear distances for automatic intervention, but the basic operation is to stomp hard. I tested it in the rain right after buying my car—once during emergency braking, it kicked in, and the car decelerated instantly, avoiding a rear-end collision. It’s pretty practical. With today’s complex urban traffic, this feature significantly reduces accident risks, though maintaining a safe distance while driving can minimize reliance on it. Remember, regular brake system maintenance is crucial, and checking tire wear helps prevent skidding.
Using the brake assist function is very simple and suitable for beginners or average car owners. During normal driving, brake operation remains the same as conventional methods. However, in emergency situations—such as when the vehicle ahead suddenly brakes or a pedestrian crosses—you need to press the brake pedal firmly and quickly without hesitation. Remember, the action must be decisive. The system will automatically recognize your force and speed. If it determines an emergency, it will immediately increase braking pressure to shorten stopping distance. After completion, the car returns to normal without requiring intervention. It's recommended to familiarize yourself with this function in a safe, open area: find a spacious zone to simulate emergency scenarios and practice braking to experience the effect. The benefit is that it can improve braking efficiency by around 20%, reducing accidents, but don’t rely on it entirely—stay alert and regularly check vehicle conditions like tire pressure to ensure the system functions properly. When buying a car, review the model manual for differences, as some require activating the assist system switch.
