Description

Technical field

[0001] The present invention relates to a vehicle control device, a program update method, and a program update system. Background technology

[0002] A vehicle is equipped with a plurality of control devices called ECU (Electronic Control Unit). Control devices such as ECU each have a storage unit that stores one or more programs executed by control units such as one or more CPUs, and each performs its own function. In order to improve the function of the control device, a method is proposed in which the program stored in the storage unit is rewritten into a newer version and updated. In particular, a solution is proposed in which the vehicle receives data for program update from an external server through wireless communication, so that the program can be updated without going to a repair factory or the like.
