Introduction of Automotive Bus

Automotive bus (automotive bus) With the automotive systems control gradually to automation and intelligent transformation, the automotive electrical system has become increasingly complex. Most of the traditional electrical systems use a single point-to-point communication method, with little contact between each other, which will inevitably form a huge wiring system. According to statistics, a traditional wiring method of high-grade automobiles, the length of its wire up to 2000 meters, electrical nodes up to l5 00, and the number of about every 10 years will increase by a factor of one. This further exacerbates the contradiction between the thick wire harness and the limited space available on the car. Whether from the point of view of material cost or work efficiency, the traditional wiring method can not be adapted to the development of modern automobiles. In addition, in order to meet the real-time requirements of the electronic system, the automotive public **** data (such as engine speed, wheel speed, throttle pedal position and other information) to implement **** enjoy, and each control unit on the real-time requirements are different. Therefore, the traditional electrical network has been unable to adapt to the development of modern automotive electronic systems, so the new automotive bus technology came into being.
