Zusammenfassung:	To provide a control system for a vehicle that can execute succession of a total running distance at the time of replacing an odometer, in a short time, while preventing falsification of the total running distance integrated by the odometer.SOLUTION: A control system for a vehicle described in the disclosure comprises a meter-side control device, mounted on the vehicle, which can measure a total running distance of the vehicle, and a back-up device that can obtain replication of the total running distance measured by the meter-side control device. An authentication signal using a common key is utilized for data communication between the meter-side control device and the back-up device. In registering a new common key between the meter-side control device and the back-up device, the larger of a value of the total running distance stored in the meter-side control device and a value of the total running distance stored in the back-up device is set as the total running distance stored in the meter-side control device.SELECTED DRAWING: Figure 4 【課題】オドメータが積算した総走行距離の改竄を防止しつつ、オドメータ交換時の総走行距離の継承を短時間で実施することが可能な車両用制御システムを提供すること。【解決手段】本開示の車両用制御システムは、車両内に搭載されて前記車両の総走行距離を測定可能なメータ側制御装置と、前記メータ側制御装置が測定した総走行距離の複製を取得可能なバックアップ装置と、を含み、前記メータ側制御装置と前記バックアップ装置との間のデータ通信は、共通鍵を用いた認証信号を利用しており、前記メータ側制御装置と前記バックアップ装置との間で新たな共通鍵を登録する際、前記メータ側制御装置に格納された総走行距離の値と前記バックアップ装置に格納された前記総走行距離の値とのうち大きい方の値を、前記メータ側制御装置の総走行距離とする。【選択図】図４
