In the car with quick response and simple structure to replace the traditional hydraulic braking system, the industry to discuss in a few years ago, many auto parts companies have been conducting research and development. Compared to conventional hydraulic brake system, electronic brake system eliminates the need for hydraulic wheel cylinders, parking brake, brake master cylinder, vacuum booster, hydraulic pumps, brake force distribution, brake system in order to achieve the simplification, the entire preparation lower quality, the growth of passenger compartment space, and can reduce the braking distance. Siemens VDO
snow in Sweden last year on electronic wedge brake system test, a test vehicle equipped with EWB from the speed of 80km / h brake to completely stationary, the braking distance of just 64.5 meters. And with a traditional hydraulic brake system ESP at the same speed and road conditions, the average braking distance to 75 meters, a full 10.5 meters shorter. This means that the test vehicle equipped with EWB system has completely stopped when the traditional hydraulic brakes are still to 30km / h speed ahead.
Obvious advantages of electronic braking systems applications in the aviation industry has been very common, and have confirmed the outstanding braking performance of the system. The reason why the delay has been applied in the car, there are two main reasons. The first is the high cost of electronic braking systems, and the second is the electronic braking system may be a result of interference of other signals misuse, whether the car's use of the environment even worse than the planes and complex, professional users also less than the aircraft. The conventional hydraulic braking system will not be around and pulsed electromagnetic signals affect their normal work, still has the advantage of simple and reliable.
Bosch , China and Siemens VDO automotive parts companies have a team of outstanding research and development charge of electronic braking systems. Recently, some European media reports, China's breakthrough in the braking system, and abandon the familiar wedge-type structure, the new design effectively solves two problems mentioned above, are close to mass production requirements. But the continent's program only in rear electronic braking system, which can compromise the future EWB Figure with electronic brake system complete, while borrowing the traditional hydraulic braking system to control costs, thus promoting technical progress.
If all four wheels on the electronic braking system, the cost increase than the conventional hydraulic brake system 20. And reliability is always the problem of these companies value most, if once the need for the recall, the company will be difficult to sustain this great loss, Mercedes-Benz brake system recall was classified as low reliability of advanced braking system typical cases.
Although the prospects of electronic braking system is very objective, but also a very large R & D costs. The Government does not provide funding for these components to support business cases, research and development can not be mass production will cause great resistance, the mainland choose compromise should be a desirable way, which will speed up the production of EWB System pace.
