Abstract

The invention provides a program rewriting system (10) for vehicles. A rewriting device (54) of the program rewriting system (10) for the vehicles receives a plurality of pieces of rewriting data each including a rewriting program and also receives information of combination suitability determination used for determining whether the combination of the plurality of pieces of rewriting data is suitable or not. The rewriting device (54) then uses the information of combination suitability determination to determine whether the combination of the plurality of pieces of rewriting data is suitable or not. If having determined that the combination is suitable, the rewriting device (54) executes the rewriting of the programs of a plurality of electronic control devices (56a-56d).

Description

technical field [0001] The invention relates to a vehicle program rewriting system, which can be used to rewrite the program of an electronic control device. Background technique [0002] With the development of computer technology, the electronicization of vehicles is being popularized. In an electrified vehicle, a plurality of electronic control units (ECUs) are generally used. The control program used by the ECU needs to be rewritten sometimes because of the upgrade {refer to the U.S. Patent Application Publication No. 2007 / 0005204 (hereinafter referred to as "US2007 / 0005204A1") and the U.S. Patent Application Publication No. 2008 / 01330680 (hereinafter referred to as "US2008 / 0133068A1")}. [0003] In US2007 / 0005204A1, data for rewriting wirelessly transmitted from a management center (200) is received by an on-vehicle data rewriting control device (100) and stored in a storage device (143). Next, the on-vehicle data rewriting control device receives the rewriting data...
