Abstract

A vehicle system includes a main control electronic control unit configured to acquire an operating rate of each of a plurality of applications arranged in at least one of a plurality of electronic control units, calculate a plurality of arrangement patterns in which the applications are arranged in the electronic control units, calculate, based on the operating rate of each of the applications, a total electric power consumption of the electronic control units when each of the arrangement patterns is implemented, and arrange the applications in at least one of the electronic control units in the arrangement pattern that has the least total electric power consumption among the arrangement patterns.

Claims

1. A vehicle system that includes a plurality of electronic control units, the vehicle system comprising a main control electronic control unit configured to

acquire an operating rate of each of a plurality of applications arranged in at least one of the electronic control units,

calculate a plurality of arrangement patterns in which the applications are arranged in the electronic control units,

calculate, based on the operating rate of each of the applications, a total electric power consumption of the electronic control units when each of the arrangement patterns is implemented, and

arrange the applications in at least one of the electronic control units in the arrangement pattern that has a least total electric power consumption among the arrangement patterns.

2. The vehicle system according to claim 1, wherein the main control electronic control unit is configured to calculate the arrangement patterns when a new electronic control unit is added to the vehicle system.

3. The vehicle system according to claim 1, wherein the main control electronic control unit is configured to calculate the arrangement patterns when a new application is added to the vehicle system.

4. The vehicle system according to claim 1, wherein the main control electronic control unit is configured to calculate the arrangement patterns when a new output unit configured to output information to be used by an application arranged in the electronic control units is added to the vehicle system.

5. The vehicle system according to claim 1, wherein the main control electronic control unit is configured to learn and update the operating rate of each of the applications.

6. The vehicle system according to claim 5, wherein the main control electronic control unit is configured to monitor the operating rate of each of the applications and appropriately update the operating rate.

7. A vehicle system comprising:

an electric power distribution unit;

a battery that is connected to the electric power distribution unit;

a main control electronic control unit that is connected to the electric power distribution unit; and

a plurality of electronic control units that is connected to the electric power distribution unit, wherein;

the electric power distribution unit is configured to supply electric power of the battery to the electronic control units and the main control electronic control unit; and

the main control electronic control unit is configured to

acquire an operating rate of each of a plurality of applications arranged in at least one of the electronic control units,

calculate a plurality of arrangement patterns in which the applications are arranged in the electronic control units,

calculate, based on the operating rate of each of the applications, a total electric power consumption of the electronic control units when each of the arrangement patterns is implemented, and

arrange the applications in at least one of the electronic control units in the arrangement pattern that has a least total electric power consumption among the arrangement patterns.
