Abstract

A program stored in a computer-readable medium causes a computer to execute a process includes receiving, from an automobile in which a control program for controlling devices mounted on the automobile operates, an update request concerning the control program, classifying a plurality of correction programs corresponding to the update request into a plurality of groups on the basis of usable electric energy of a battery corresponding to a vehicle type to which the automobile belongs, an amount of the usable electric energy being stored in a memory, and transmitting the classified correction programs to the automobile for each of the groups.

Claims

1. A computer-readable recording medium having stored therein a program for causing a computer to execute a process comprising:

receiving, from an automobile in which a control program for controlling devices mounted on the automobile operates, an update request concerning the control program;

classifying a plurality of correction programs corresponding to the update request into a plurality of groups on the basis of usable electric energy of a battery corresponding to a vehicle type to which the automobile belongs, an amount of the usable electric energy being stored in a memory; and

transmitting the classified correction programs to the automobile for each of the groups.

2. The computer-readable recording medium according to claim 1, wherein

the classifying includes classifying the plurality of correction programs into a plurality of groups when a total value of expected power consumption used for installing a correction program for the control program in a control unit configured to execute the control program and mounted on the automobile is larger than the amount of the usable electric energy.

3. The computer-readable recording medium according to claim 2, wherein

the classifying includes classifying the plurality of correction programs into groups, a number of which determined on the basis of the total value of the power consumption and the usable electric energy.

4. The computer-readable recording medium according to claim 1, the process further comprising:

receiving confirmation information indicating whether the correction program classified into a first group among the plurality of groups is normally received, wherein

the transmitting includes, after confirming with the confirmation information that the correction program classified into the first group is normally received, starting transmission of the correction program classified into a second group among the plurality of groups.

5. The computer-readable recording medium according to claim 2, the process further comprising:

calculating the total value of the power consumption on the basis of power consumption used for installing a correction program of a unit size stored in a memory in association with each the control unit.

6. A computer-readable recording medium having stored therein a program for causing a computer to execute a process comprising:

receiving correction programs, which are classified into a plurality of groups on the basis of usable electric energy of a battery corresponding to a vehicle type to which an installation target automobile belongs, for each of the groups; and

installing, according to a battery residual capacity of the installation target automobile, the classified correction programs for each of the groups.

7. The computer-readable recording medium according to claim 6, wherein

the installing includes installing, at timing when the installation target automobile is expected to stop for a predetermined time or more, the correction program classified into any one of the plurality of groups.

8. The computer-readable recording medium according to claim 6, wherein

the installing includes installing the correction program classified into any one of the plurality of groups when a battery residual capacity of the installation target automobile is equal to or larger than a predetermined threshold.

9. An information processing method comprising:

receiving, from an automobile in which a control program for controlling devices mounted on the automobile operates, an update request concerning the control program;

classifying, by a processor, a plurality of correction programs corresponding to the update request into a plurality of groups on the basis of usable electric energy of a battery corresponding to a vehicle type to which the automobile belongs, an amount of the usable electric energy being stored in a memory; and

transmitting, by the processor, the classified correction programs to the automobile for each of the groups.

10. An information processing method comprising:

receiving correction programs, by a processor, which are classified into a plurality of groups on the basis of usable electric energy of a battery corresponding to a vehicle type to which an installation target automobile belongs, for each of the groups; and

installing, by the processor, according to a battery residual capacity of the installation target automobile, the classified correction programs for each of the groups.

11. An information processing apparatus comprising:

a memory configured to store an amount of usable electric energy of a battery of an automobile in association with a vehicle type of the automobile; and

a processor configured to receive, from the automobile in which a control program for controlling devices mounted on the automobile operates, an update request concerning the control program, to refer to, in the memory, the amount of usable electric energy corresponding to the automobile in which the control program operates and classify a plurality of correction programs corresponding to the update request into a plurality of groups on the basis of the amount of the usable electric energy referred to, and to transmit the classified correction programs to the automobile for each of the groups.

12. An information processing apparatus comprising:

a processor configured to receive correction programs, which are classified into a plurality of groups on the basis of usable electric energy of a battery corresponding to a vehicle type to which an installation target automobile belongs, for each of the groups, and to install, according to a battery residual capacity of the installation target automobile, the classified correction programs for each of the groups.
