The new BMW 5 series by first collision tests
The new BMW 5 series
CRI news until now, whether or not the vehicle safety is through collision tests, identification of the test, the vehicle's structural integrity and constraint system in non-braking situations be tested. , However, because modern automotive electronic system development, preventive protection system has been able to before the accident advance warning motorists and collision inevitable when drivers and cars. A growing number of cars to start the installation of such systems, including the new BMW 5 series and the BMW 7 series.
The future of collision tests must consider preventive protection system. In the most recent first collision test BMW in , 530d passed Germany motor supervision Association (DEKPA) tests, and tests taking into account the effect of the brake intervention system.
Each of these drivers are all on this familiar: road suddenly while driving a car blocking growth team, if the driver attention deficit disorder or attention, rear-end collision is unavoidable. In the road accident casualties, it accounted for 40%. In order to reduce the threat of this type of situation, BMW 5 and some high-end vehicles have already installed the preventive security system.
The new BMW 5 series
The new BMW 5 series can be installed Active cruise control system that integrates with brake intervention capabilities of rear-end collision warning system that can automatically adjust speed, ensure that the vehicle in maintaining a safe distance. If the system is aware of a possible collision with the vehicle, and the head-up display in the dashboard is on red alert sign on. While braking system for pre-brake and hydraulic brake assist system triggers the braking force of the lowest rates. This ensures that when the drivers of emergency brake, brake faster, thereby significantly reducing the braking distance. If a collision is very likely to occur at once, the second phase of the collision warning system starts. In particular, the need for drivers to intervene quickly, the system continues to display warning signs, but also make a sound alert, if motorists on the brakes do not respond to the request, the system will start a limited-time braking procedures slow down (1.2 seconds) by motorists at the speed was reduced to brake.
Under the new BMW 5 active cruise control system sensor information, if the driver does not react to avoid collision, the system starts emergency braking feature, ensure that the significant drop in the collision speed. According to the usual EuroNCAP crash test processes, vehicle at 64 km/h speed collision barrier for front-end side collision test. The DEKRA testing using BMW 530d installed advanced braking intervention system, while also speeding up to 64 km/h, but in the moment before the collision, the impact speed was reduced to 40 km/h.
As the car before the collision, and auto complete brake pitching movement arising, the car will change its orientation, particularly at the front bumper block of time. And did not install the system in vehicles, auto install after crash ahead of brake system will be slightly lower in position. More importantly, slow down, passengers also have the possibility of appearing before the flush, but uses the advanced braking system, the severity of the collision will be significantly reduced, thus providing passengers with better protection.
Previously, the test organization have not been agreed in the collision tests on preventive passenger protection system for verification. BMW this and DEKRA in cooperation with the Verify test is a test before the next crash scene is the first step, in the next few years, an increasing number of vehicles will be on active safety systems innovation more attention. （yoyo）
