Hybrid and electric vehicles have opened up the option to improve fuel economy by converting kinetic energy through regenerative braking of the generator into electrical energy to charge the battery. Because of the powertrain electrification, the NVH requirements become even stronger, and the vacuum source for brake boosters is removed completely. The vacuum must then be generated either by a mechanical vacuum pump attached to the engine or an electric vacuum pump. Future CO2 emissions targets have resulted in gasoline engines that no longer have sufficient vacuum for brake boosters in all operating conditions. In addition to high expectations regarding reliability and availability of safety-related brake systems (whilst keeping costs low), there are new demands arising from the introduction of more and more Advanced Driver Assistance Systems (ADAS), as well as more efficient engines, and electric powertrains.įor ADAS, this means both increasing relevance of Noise, Vibration and Harshness (NVH) regarding features such as adaptive cruise control to standstill and the need for substantially higher pressure build dynamics for new safety features.

Since the introduction of the Electronic Stability Program (ESP) in 1995, brake system requirements have changed significantly. With the electromechanical brake booster, iBooster, Bosch meets these requirements without changing the established brake system layout.

The increased efficiency of conventional internal combustion engines, the growing market penetration of electric powertrains, the requirements for higher safety, and the demand for automated driving have resulted in new requirements for brake systems.
