Abstract

A bus system for a motor vehicle comphises a first bus 101, a transmission control unit 103 connected to said first bus an engine control unit 104, and a first actuator 108 for driving a shifting operation in a gearbox of the vehicle under control of the transmission control unit(TCU)103. The transmission control unit is connected to a gear selector 106 and to a clutch 111 by a second bus 102. Preferably the second bus has a greater bandwidth than the first bus. The TCU is preferably disposed between a clutch pedal and said clutch for controlling the clutch with respect to the said pedal position. The said gear selector shift-by-wire system simulates such a mechanical shifting system by use of the gear shifter as shown in figure 2.
