A recent history: applications of microsystem technology in the automotive industry

Summary/Abstract: This paper discusses some of the more interest ing applications of Microsystems technology in current and future vehicle electronic systems and the challenge for designers because the cost of the new electronics cannot prohibit the economic production of automobiles. This hurdle must be cleared before cars with 42 V systems will become available to consumers. In the paper it is described how „by wire” systems will work in aiding the driver in steering, stabilizing and braking the car. The basic concept of „by wire” sounds simple enough: replace the car’s mechanically linked hydraulic systems steering and braking, for example with electronic ones. But performance and handling improvements under the hood, such as dynamic stability controls, electronic suspensions and precision controlled fuel injection also need power from the 14 V system featured in today’s cars. To handle the situation, automotive manufactures and suppliers are embracing a 42 V standard for system voltage as they design new products. In the summer of the 2013 year, the world’s first production of the. Steer „by wire” car has been constructed and sold. The steering gear talks to a computer and the computer talks to the wheels.
