An on-vehicle gateway is provided that is interposed between a plurality of buses for transferring data, and that is capable of performing appropriate control according to situations. (1) Data coming from one bus are analyzed to filter false data and unwanted data not to feed them to the other buses. (2) When the state of an on-vehicle device is inquired, it is controlled according to the state of an IG power source whether the inquiry is to be made to the device or the on-vehicle gateway answers the inquiry by proxy. (3) The response of the gateway is changed according to the place where a vehicle is traveling. For example, control is performed such that, while the vehicle is traveling on a local road, the transmission/reception of a mobile telephone is available by using a hands-free system, and that, while the vehicle is traveling on an expressway, the transmission/ reception of a mobile telephone is unavailable even by using the hands-free system. (4) The response of the gateway is changed according to a driver. For example, if the years of driving experience of the driver is within one year, the gateway stops data transfer so that no television screen or navigation screen is displayed during driving, and that the transmission/ reception of the telephone by the hands-free system is unavailable. <IMAGE>
