Vehicle control apparatus and failure information management system

Abstract

A vehicle control apparatus (1) according to the present invention includes: an electronic control unit (4) performing electronic control related to a vehicle (10); and an in-vehicle device (2) configured to be able to communicate with the electronic control unit (4). The in-vehicle device (2) is able to support a plurality of communication protocols, for communication with the electronic control unit (4). The in-vehicle device (2) includes: a connected ECU identification section (2a) that, when failure diagnosis is started, identifies the electronic control unit (4) installed in the vehicle (10); and a communication protocol ascertainment section (2b) that ascertains, among the communication protocols, the communication protocol supportable by the electronic control unit (4) identified by the connected ECU identification section (2a), and communicates with the electronic control unit (4) identified by the connected ECU identification section (2a), based on the communication protocol ascertained by the communication protocol ascertainment section (2b).
