ON-BOARD APPARATUS, ON-BOARD SYSTEM, CONTROL METHOD, AND COMPUTER PROGRAM

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.
