Abstract

This vehicle communication system is suitable for high speed communication with small signal distortion. The communication system for a vehicle includes, provided with charge and discharge that allow a distributed capacitance of a signal line to be discharged by making a stored charge by-pass a pull-up resistor, or causing the distributed capacitance of the signal line 5 to be charged up by making a charge by-pass a pull-up resistor. The charge and discharge units charge or discharge for only a fixed period of time. This fixed period of time is shorter than 1 bit length of the signal, from when transistors are switched from on to off. For a node connected through the signal line, this fixed period of time is longer than the time taken for a reception circuit that is providing a reception signal from the signal line to switch on or off.
