emergency brake, automatically increases brake force to shorten braking distances, improve security.
1. The brake assist advantages
Even if the brakes weak force, but also the occurrence of a large braking force. For lack of women such as the elderly or people ankle leg strength, the advantage of this system is more obvious. Automatic power to help reduce the pedal is released, reducing the sense of not suited when braking.
2. The brake assist technical principle
EBA brake assist or the like is generally referred to as a BAS. By resolving sensor where the driver’s pedal, and determines whether the identified emergency braking procedure is introduced. Whereby the system can immediately stimulate maximum brake pressure to achieve the highest possible braking effect. It works with the anti-lock brake system (ABS).
ABS braking distance can be shortened, and prevents loss of control during braking, thereby reducing the risk of accidents. But in the case of emergency braking the driver often due to indecisive or insufficient braking force can not be quickly triggered stampede ABS braking time wasted, thereby achieving the desired results.
For this reason, automotive engineers have designed Brake Assist, which allows existing ABS has some intelligence, when the fast when the brakes when a large force, BAS to determine the driver in emergency braking and let ABS work quickly increase the braking force.
3. Brake Assist misunderstanding
In case of emergency, the driver’s control is most critical, brake assist, ABS and other security configuration just helpful. Not the back of the head “safe driving” and “traffic laws” throwing.
Mechanical brake assist points and an electronic control two.
Mechanical brake assist is actually slightly modified based on the ordinary brake booster made, when there is less braking force, it acts as a booster, the braking force increases with pressure biasing chamber pressure is increased to start the ABS.

4. The brake assist related reading
can brake assist (IBA) a so-called intelligent brake assist is IBA (IntelligentBrakeAssist), its use is in a low speed can be self assisted by computer brake even the car stopped completely, on behalf of the brand Infiniti. IBA distance judged by the radar system and the vehicle in front, direction and relative velocity, to detect if the driver should take measures to avoid potential direct rear collision warning light will light up accompanied by the driver to sound the alarm be reminded.
In addition, if the system determines that the measures taken in the driver still can not avoid the collision, the brake will be applied to reduce vehicle speed and help reduce and mitigate collision damage.
