A determination section 65 determines whether a response signal to the effect that the signal information is received can be received from the road side device. When the determination section 65 determines that there is no response signal from the road side device, a control section 61 controls update signal information updated by an update section 66 so as to be re-transmitted from the transmission section 63. In this case, the update section 66 updates the signal information transmitted to the road side device in accordance with a time lag from a point of time of transmitting transmission information received by the reception section 62 to a point of time of re-transmitting the update signal information.</p> |
