1. A vehicle wireless communication device that is mounted on a vehicle and configured to communicate with a device outside of the vehicle, the vehicle wireless communication device comprising:
a transmission portion that transmits radio waves;
a reception portion that receives radio waves;
a positioning portion that performs a positioning function to determine a position of the vehicle based on signals received from a global navigation satellite system (GNSS);
a temperature acquisition portion configured to acquire a temperature of the vehicle wireless communication device; and
a function controller configured to:
determine whether the temperature of the vehicle wireless communication device is greater than a repression threshold and whether a change rate of the temperature of the vehicle wireless communication device is positive;
in response to determining that the temperature of the vehicle wireless communication device is greater than the repression threshold and that the change rate of the temperature of the vehicle wireless communication device is positive, (1) repress the transmission of radio waves by the transmission portion, or the reception of radio waves by the reception portion, and (2) repress the positioning function by the positioning portion; and
in response to determining that the temperature of the vehicle wireless communication device is not greater than the repression threshold or that the change rate of the temperature of the vehicle wireless communication device is not positive, restitute a repressed function.
