Abstract
A communication control unit for a vehicle is configured to be coupled to a first bus that couples control units to each other in the vehicle. The communication control unit includes a determination module and a communication control module. The determination module comprehensively determines whether to prohibit initialization of respective pieces of malfunction information stored in the control units, on the basis of a state of the vehicle. The communication control module transmits, to the first bus, an initialization control signal for controlling whether to prohibit the initialization of the malfunction information on the basis of a result of the determination made by the determination module.

A communication control unit for a vehicle, the communication control unit being configured to be coupled to a first bus that couples control units to each other in the vehicle and comprising:
- a determination module configured to comprehensively determine whether to prohibit initialization of respective pieces of malfunction information stored in the control units, on the basis of a state of the vehicle;
- and
- a communication control module configured to transmit, to the first bus, an initialization control signal for controlling whether to prohibit the initialization of the malfunction information on the basis of a result of the determination made by the determination module.
A communication control system for a vehicle, the communication control system comprising
- one or more control units and a communication control unit for the vehicle that are coupled to each other via a first bus,
- wherein the communication control unit for the vehicle comprises
- a determination module configured to comprehensively determine whether to prohibit initialization of respective pieces of malfunction information stored in the control units, on the basis of a state of the vehicle, and
- a communication control module configured to transmit, to the first bus, an initialization control signal for controlling whether to prohibit the initialization of the malfunction information on the basis of a result of the determination made by the determination module, and
- each of the one or more control units determines whether to initialize the malfunction information in response to an initialization request received from an external unit, depending on the initialization control signal received from the communication control unit for the vehicle via the first bus.
