Vehicle control system and vehicle control method

A vehicle control method to be executed by a computer for, in a vehicle performing wireless communication with a mobile terminal, controlling implementation of the wireless communication, the vehicle control method comprising:

• a first position measuring step of measuring a position of the mobile terminal with respect to the vehicle by performing first position measuring processing involving implementation of the wireless communication between the mobile terminal and the vehicle;
• a second position measuring step of measuring a position of the mobile terminal with respect to the vehicle by performing second position measuring processing involving implementation of the wireless communication between the mobile terminal and the vehicle, having less power consumption in the vehicle by the wireless communication than that of the first position measuring processing and having lower precision of position measurement than that of the first position measuring processing;
• a control operation execution instruction recognizing step of recognizing an instruction to execute a control operation in the vehicle;
• and
• a position measurement control step of determining whether measurement of a position of the mobile terminal for executing the control operation is to be executed by the first position measuring step or to be executed by the first position measuring step and the second position measuring step in accordance with a type of the control operation for which an execution instruction is recognized by the control operation execution instruction recognizing step.
