Document Type and Number:
WIPO Patent Application WO/2020/095645
Kind Code:
A1
Abstract:
A program update system, comprising a plurality of general-purpose ECUs capable of executing a plurality of types of programs and exhibiting different functions depending on the type of a program to be executed, wherein the general-purpose ECU includes an active ECU that is in a state of outputting information for controlling a vehicle-mounted device mounted in a vehicle and a standby ECU that is in a state of not outputting information for controlling the vehicle-mounted device. When updating the program, the standby ECU acquires the update program transmitted from an external server outside of the vehicle, stores the acquired update program in the storage unit of the ECU, and transitions to active ECU that outputs information for controlling the vehicle-mounted device. The active ECU that is executing the program of the previous version of the update program stops outputting information for controlling the vehicle-mounted device, and transitions to standby ECU.
