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. With the electromechanical brake booster, iBooster, Bosch meets these requirements without changing the established brake system layout.
MARKET ENVIRONMENT
Since the introduction of the Electronic Stability Program (ESP) in 1995, brake system requirements have changed significantly. 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.
For 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. Future CO2 emissions targets have resulted in gasoline engines that no longer have sufficient vacuum for brake boosters in all operating conditions. The vacuum must then be generated either by a mechanical vacuum pump attached to the engine or an electric vacuum pump. Because of the powertrain electrification, the NVH requirements become even stronger, and the vacuum source for brake boosters is removed completely.
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. To produce this in a comfortable manner, the brake system needs to “blend” the braking torque of the generator. The introduction of automated driving requires redundancy within the brake system, in order to guarantee deceleration of the vehicle even in the event of failure.

Sound Generation For Enhanced Road Safety
With an ever-increasing number of fully electric and hybrid vehicles entering the market, we are witnessing a change in the acoustic experience in and around the car. The silent nature of the electric powertrain means that other road users miss the familiar acoustic cues that warn them of an approaching vehicle. To remedy this situation, Harman is working on various noise management solutions.
OBJECTIVE ASSESSMENT OF THE SAFETY CONTRIBUTION OF TODAY'S AUTOMOTIVE HEADLAMPS
Good lighting makes a major contribution to road safety. In 2011, the International Commission on Illumination (CIE) presented an evaluation system for headlamps that can objectively assess the quality of illumination and glare limitation. New light sources like LEDs and lighting functions (glare-free high beam, partial high beam) have been available for several years, so that an extension of the proven CIE method is necessary, which takes into account, among other things, changed switch-on and service lives of new lighting functions and represents a generally understandable evaluation system. An evaluation system presented in the following by the Technische Uni versität Darmstadt, which was developed by an encompassing expert commission, is intended to provide representative data and enable an objective evaluation of headlamp performance.
RAPIDO RE-INNOVATES TO CATER TO POST COVID-19 LAST MILE CONNECTIVITY
The rapid pace of urbanisation in the country has witnessed cities expanding and subsuming surrounding villages and smaller towns, evolving into Tier II and III cities.
FUNCTIONAL SAFETY STANDARDS TOP PRIORITY FOR FUTURE AUTOMOTIVE DEPLOYMENT
Increasing levels of electronic content in vehicles result in a large amount of software that is required to run the scenes behind the mechanical aspects of a vehicle. Electronic systems in automobiles are part of every section, from the powertrain to comfort and convenience systems as well as all types of safety equipment. This makes electronics and the software running these systems a critical part of the equation for future mobility solutions. In addition, putting standards in place to measure methods of developing, testing and functioning of such electronic systems also becomes highly relevant.
“BYD'S EV STRATEGY TO ENCOMPASS MOST FORMS OF TRANSPORTATION NEEDS IN INDIA”
The country’s electric vehicle (EV) ecosystem is grappling with a plethora of challenges even as it is striving to wriggle itself out of the ‘nascent stage’ tag. In an exclusive chat with Auto Tech Review, Zhang Jie Ketsu, Executive Director, BYD India shares his perspective on the current EV scenario and how the company intends to progress faster in the Indian automotive industry
SAFETY IN ELECTRIC AND AUTONOMOUS CARS – SIMULATION OF COMPLEX CRASH SCENARIOS
Electric and autonomous vehicles allow for novel seating arrangements and packaging strategies, presenting new safety challenges. Physical crash testing must be supplemented with virtual simulation to ensure vehicle safety on shorter development cycles. With its Simcenter Madymo MBS software, Siemens provides improved runtimes and the Active Human model, enabling accurate and rapid occupant safety analysis in complex crash scenarios.
