With the increasing popularity of automobiles, with the frequent occurrence of accidents, traffic safety issues have been paid more and more attention. Usually, in the event of a traffic accident, due to the driver’s loss of consciousness or vehicle failure can not control, the vehicle may shift in an unpredictable direction, very easy to cause secondary accidents, and in all kinds of traffic accidents, secondary accidents caused by the injury is even more serious.
Hyundai Kia officials recently announced that, to avoid a second accident, the Kia’s fourth-generation Solanto and Genesee G80 will be equipped with mcB system (Multi-Brake, crash-proof automatic braking system).
Several studies have shown that when a vehicle collides, automatic forced braking of a car can effectively reduce the chance of a secondary accident. Similar systems, such as MCBs, can reduce secondary accident rates by 30 percent, according to a paper published in the journal NHTSA.
It is understood that the modern Kia’s MCB system is composed of a number of controllers and sensors, MCB’s first line of defense is the airbag control kit (ACU), as soon as the kit sensed a front or side collision of the vehicle, the airbag is immediately released.
The second line of defense is the wheel speed sensor and inertial measurement kit (IMU), which first evaluates the current speed and movement of the car and checks the pedal for driver involvement, such as manual braking or acceleration.
If the MCB determines that the driver does not have a pedal or a stampede force is not strong enough after the airbag is ejected, then the electronic stability control mechanism (ESC) is activated, the corresponding braking force is applied to the wheels to the wheel sewage to prevent secondary accidents.
Hyundai Kia is equipped with a third-generation controller local area network (CAN Communication) for vehicles, processing up to 200 megabytes of data per second, officials said. In this way, the car controller and sensors will sense the first collision and instantly transmit the data to the system, enabling the ESC to brake automatically in a timely manner to prevent secondary accidents. The MCB’s braking power will cause the vehicle to slow down at a rate of 5 mph (18km/h).
It is worth mentioning that the MCB functions normally and also needs to meet certain prerequisites. First, the speed cannot exceed 180km/h, as a sudden brake at high speed sits at a high speed that can cause a more serious secondary accident. Second, the MCB system will automatically deactivate as soon as it detects that the driver has pressed the accelerator pedal. Finally, once the vehicle is stopped under the action of the MCB, the MCB will determine that the system has completed its tasks and is deactivated within two seconds, and the driver will need to manually control the vehicle as the actual situation is.
It is reported that hyundai car this year and next year will be introduced 16 new cars will be installed MCB system.
