[email protected] com Summary: Brake-by-wire presents the replacement of traditional braking mechanism components including pumps, tubes, fluids, brake boosters, and master cyl by digital sensors and actuators. The different design of these types of brake concepts poses new challenges pertaining to the automotive industry with regard to availableness and fallback levels in comparison to standard conventional brake systems. This contribution focuses on the development of appropriate fallback level principles. Hardware-in-the-loop (HIL) techniques and field trials will be used to look at the functionality and the functionality of these kinds of systems. Keywords and phrases: Brake-by-wire, Fallback level, Hardware-in-the-loop (HIL), Field trial
1 ) Introduction The final three decades of automotive design have primarily been inspired by x-by-wire-technologies. Besides steer-by-wire and throttle-by-wire a major take into account developing driving dynamics was and still is the brake-by-wire technology, e. g. the Electro Mechanical Brake pedal (EMB) and the die Electronica Hydraulic Brake pedal (EHB). The first setup of the brake-by-wire technology in the automobile record was the EHB system of japan automotive dealer ADVICS (subsidiary of Toyota) at the beginning of the year 2001 inside the Toyota Estima Hybrid. In September of the identical year the first EHB system SBC (Sensotronic Braking mechanism Control) from the worldВґs most significant automobile dealer BOSCH was presented in the International Motorshow at The netherlands (IAA) . The SBC was implemented inside the Mercedes-Benz S- and C-Class and in the luxury car company Maybach. Several performance concerns of the electro-hydraulic brake system required Mercedes-Benz to recall 680. 000 vehicles of the E-Class and SLClass in May 2005. Further difficulties arose in the low functionality of the mechanic-hydraulic fallback standard of the SBC system . The Mercedes and Maybach individuals simply did not accept the fallback level concept of SBC in spite of the very fact, that it was built to match the legal regulations with a minimum deceleration of two, 44 m/s2 at a pedal pressure 500 D. The wide range of customer issues in the end forced Mercedes Benz in the year 2006 to the biggest recall (1. 3...
