First Claim
1. A vehicle control system comprising:
- a radio wave transmitting body that transmits information using a radio signal;
a first electronic control device that receives the radio signal from the radio wave transmitting body; and
a second electronic control device that receives the radio signal from the radio wave transmitting body,wherein the first electronic control device includes;
a first transmitting/receiving unit that transmits and receives the radio signal;
a first information acquisition unit that acquires the information, which is transmitted from the radio wave transmitting body, from the radio signal received by the first transmitting/receiving unit; and
an information repeater that passes the information acquired by the first information acquisition unit to the second electronic control device by transmitting the radio signal from the first transmitting/receiving unit, andwherein the second electronic control device includes;
a second transmitting/receiving unit that receives the radio signal from the radio wave transmitting body and the first electronic control device;
a second information acquisition unit that acquires the information, which is transmitted from the radio wave transmitting body, from the radio signal received by the second transmitting/receiving unit;
a third information acquisition unit that acquires the information, which is passed by the first electronic control device, from the radio signal received by the second transmitting/receiving unit; and
a controller that controls a device of a vehicle based on the information acquired by the second information acquisition unit or the third information acquisition unit.
