- the acquisition unit 50 acquires the inverter program 24A that corresponds to the changed state from the server 12, for example, via the network 16.
- the execution unit 52 executes the installation or activation of the inverter program 24A acquired by the acquisition unit 50. This is because, when the external environment changes, the inverter 22 should be controlled by the inverter program 24A that is appropriate for that external environment.
- the acquisition unit 50 may acquire the inverter program 24A that corresponds to the changed driving area.
- the acquisition unit 50 may acquire the inverter program 24A corresponding to the region beyond the regional border.
- regions include, but are not limited to, countries, continents, states, prefectures, cities, towns, and villages.

- the acquisition unit 50 may acquire the inverter program 24A that corresponds to the electromagnetic wave regulations of the country across the border. For example, there are countries such as Europe that have strict electromagnetic wave regulations. For this reason, when the driving area of the vehicle 14 crosses a border, the acquisition unit 50 may acquire the inverter program 24A that corresponds to the electromagnetic wave regulations of the country across the border, that is, the inverter program 24A that controls the inverter 22 at a drive frequency that suppresses the generation of electromagnetic waves.
- the acquisition unit 50 may also acquire the inverter program 24A that corresponds to the changed characteristics of the driving area.
- the characteristics of the driving area are characteristics that should be taken into consideration in controlling the inverter 22 when the vehicle 14 is traveling.
- the inverter program 24A that enables the vehicle 14 to stop and start smoothly may be acquired.
- the inverter program 24A may be acquired with the drive frequency of the inverter 22 set to a frequency in the audible range so that people can become aware of the presence of the vehicle 14.
- the inverter program 24A may be acquired to control the inverter 22 so that the drive torque of the motor 34 is kept low, compared to areas with relatively few traffic accidents.
- the acquisition unit 50 can acquire a GPS signal of the vehicle 14 from the GPS receiver 35 mounted on the vehicle 14, it may determine whether or not the driving area of the vehicle 14 has changed to a driving area in which the inverter program 24A should be changed based on the acquired GPS signal, and if the GPS signal cannot be acquired, it may determine whether or not the driving area of the vehicle 14 has changed using a communication address for communicating with an external device via the network 16. For example, there may be cases where the GPS receiver 35 is unable to acquire a GPS signal due to a malfunction or the like. Thus, if the GPS signal cannot be acquired, the driving area of the vehicle 14 may be identified using a communication address such as an IP address. Note that the communication address is not limited to an IP address as long as it can identify the driving area.

- the inverter program 24A may be acquired with a lower drive frequency for the inverter 22 compared to an area with a low average temperature, so that the temperature of the inverter 22 does not become too high.
- the acquisition unit 50 may also acquire weather information as weather information, and when the acquired weather information changes, acquire the inverter program 24A corresponding to the changed weather information.
- Weather information can be obtained, for example, by identifying the area in which the vehicle 14 is traveling based on the GPS signal received by the GPS receiver 35, and requesting weather information for the identified area from the server 12 via the network 16.
- the inverter program 24A may be acquired, which has a torque profile that allows stable driving without slipping.
- step S100 the CPU 40A determines whether or not a GPS signal has been received from the GPS receiver 35. If the GPS signal has been received, i.e., if the current position of the vehicle 14 can be obtained based on the GPS signal, the process proceeds to step S101. On the other hand, if the GPS signal cannot be received, i.e., if the current position of the vehicle 14 cannot be obtained based on the GPS signal, the process proceeds to step S102.
- step S101 the CPU 40A calculates the current position of the vehicle 14 based on the GPS signal obtained from the GPS receiver 35.
- step S102 the CPU 40A obtains the current location of the vehicle 14 from the IP address used when communicating with external devices such as the server 12 via the network 16.
- step S103 the CPU 40A determines whether the driving area of the vehicle 14 has changed to one in which the inverter program 24A should be changed, based on the current position of the vehicle 14 acquired in step S101 or step S102. That is, as described above, it determines, for example, whether a border has been crossed, whether the characteristics of the driving area have changed, etc. Then, if the driving area of the vehicle 14 has not changed to one in which the inverter program 24A should be changed, the process proceeds to step S104. On the other hand, if the driving area of the vehicle 14 has changed to one in which the inverter program 24A should be changed, the process proceeds to step S105.
- step S104 the CPU 40A installs or activates the inverter program 24A.
- the inverter program 24A to be installed i.e., the inverter program 24A corresponding to the region in which the vehicle 14 runs
- the server 12 is installed in the storage unit 24.
- the inverter program 24A corresponding to the region in which the vehicle 14 runs has already been installed and activation of the inverter program 24A is to be performed
- activation of the inverter program 24A is performed.
- the installation or activation of the inverter program 24A is performed by the communication ECU 18 of the vehicle 14.
- step S105 the CPU 40A acquires weather information for the area in which the vehicle 14 is traveling.
- the CPU 40A requests and acquires weather information for the current location of the vehicle 14 acquired in step S101 or step S102 from the server 12.
- step S106 the CPU 40A determines whether the weather information for the region in which the vehicle 14 is traveling, acquired in step S105, has changed to weather information that requires the inverter program 24A to be changed. That is, as described above, it determines, for example, whether the temperature information has changed and whether the weather information has changed. Then, if the weather information for the region in which the vehicle 14 is traveling has changed to weather information that requires the inverter program 24A to be changed, the process proceeds to step S107. On the other hand, if the weather information for the region in which the vehicle 14 is traveling has changed to weather information that requires the inverter program 24A to be changed, this routine is terminated.
- step S107 similar to step S104, the CPU 40A installs or activates the inverter program 24A.
- the inverter program 24A to be installed i.e., the inverter program 24A corresponding to the weather information for the region in which the vehicle 14 is traveling
- the server 12 is installed in the storage unit 24.
- the inverter program 24A corresponding to the weather information for the region in which the vehicle 14 is traveling has already been installed and activation of the inverter program 24A is to be performed, activation of the inverter program 24A is performed.
- the installation or activation of the inverter program 24A is performed by the communication ECU 18 of the vehicle 14.
- the inverter program 24A that controls the inverter 22 of the vehicle 14 when the external environment of the vehicle 14 changes to a state in which the inverter program 24A that controls the inverter 22 of the vehicle 14 needs to be changed, the inverter program 24A that corresponds to the changed state is obtained and installed or activated. This allows the inverter 22 to be appropriately controlled in response to changes in the external environment of the vehicle 14.
