Abstract
An on-board apparatus is connected to a plurality of ECUs which include: a first ECU; and a second ECU. The first ECU includes: a first transceiver which, upon receiving a control message corresponding to a matching pattern recorded in a register of the first transceiver, switching the first ECU to a normal mode from a sleep mode, and a second transceiver switching the first ECU from the sleep mode to the normal mode upon receiving a predetermined activation signal. The on-board apparatus includes: a storage unit that stores therein a wake-up pattern for switching the first ECU from the sleep mode to the normal mode; and a control unit that transmits the activation signal if a first activation notification indicating that the first ECU has switched to the normal mode is not received within a predetermined amount of time after receiving a control message corresponding to the wake-up pattern.
