Electronic braking system may replace traditional brake

According to the recent Siemens VDO companies in the snow in Sweden, a test showed that one equipped with electronic braking system EWB the test vehicle speed from 80 km / h to brake completely static, need to 64.5 m distance. And the same vehicles with ESP assembly of the conventional hydraulic braking system for testing, the same as under the average traffic speed and braking distance to 75 meters, which means that with the test vehicle EWB system has been completely stopped, the traditional hydraulic Brake car is still 30 km / h speed ahead.

In fact, the concept of electronic braking system many years ago is the focus of the controversy, many auto parts company's research and development work has also been carried out quietly. Compared to conventional hydraulic braking system, electronic hydraulic braking system eliminates round cylinder, live car braking device, the brake master cylinder, vacuum booster, hydraulic pump system of power distribution, so as to achieve the simplified brake system, by reducing the weight of the whole, the growth of space beneath, and can significantly reduce braking distance. The reason has been unable to use in the car, why there are two main aspects. The first is the electronic braking system higher costs, and the second is the electronic braking system may be other signal interference caused by misuse, after all, the use of car environment even worse than the aircraft and complexity, not professional users and aircraft. The conventional hydraulic braking system will not be around electromagnetic pulse signals and affect their normal work, still has the advantages of simple and reliable.

Recently, the electronic braking system there has been a new R & D progress, the European electronics companies in a vehicle braking system design breakthrough has been achieved, they abandoned the common wedge-style structure, the new design an effective solution to the mentioned two issues has been close to volume production requirements. But the new options only in the use of electronic rear brake system, which can compromise the future of EWB wedge electronic braking systems accessories, while borrowing conventional hydraulic braking system to control costs in order to advance technological progress. If all four wheels on the electronic braking system, the cost than traditional hydraulic braking system increased by 20%. Reliability has always been and the value of these companies, if it needs to be amended, the company will be difficult to sustain such a huge loss.
