Vehicular program rewriting system, vehicular master device, progress state synchronization control method, and progress state synchronization control program

Abstract

In a vehicular program rewriting system (1), a vehicular master device (11) is provided with: a first progress state determining unit (88a) for determining a first progress state relating to rewriting of a program; a first progress state transmitting unit (88b) for transmitting the first progress state determined by the first progress state determining unit to a center device; a second progress state acquiring unit (88c) for acquiring a second progress state relating to the rewriting of the program from the center device; and a first display instructing unit (88d) for instructing the creation of content capable of being displayed on a display terminal mounted in a vehicle, on the basis of the first progress state determined by the first progress state determining unit, and the second progress state acquired by the second progress state acquiring unit.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on Japanese Application No. 2018-151420 filed on August 10, 2018 and Japanese Application No. 2019-129960 filed on July 12, 2019, the contents of which are incorporated herein by reference. technical field

[0003] The present disclosure relates to a vehicle program rewriting system, a vehicle host device, a synchronous control method of a progress state, and a synchronous control program of a progress state. Background technique

[0004] In recent years, with the diversification of vehicle control such as driving assistance functions and automatic driving functions, the scale of programs such as vehicle control and diagnosis of an electronic control unit (hereinafter, referred to as an ECU (Electronic Control Unit)) mounted on the vehicle has increased. bigger. In addition, there are more and more opportunities to rewrite (reprogram) ECU programs along with version upgrades based on functiona...
