Description

To achieve the above objective, the position detection system according to this disclosure is a position detection system for detecting the position of a portable device (9) relative to a vehicle (Hv) for vehicle control purposes , A communication module (2) installed in the vehicle and performing wireless communication with a mobile device using a first communication method, The communication module is configured to enable wireless communication with a mobile device using a second communication method different from the first communication method. A determination unit (S325, S410) determines whether or not the mobile device supports wireless communication using the second communication method based on wireless communication with the mobile device using the first communication method, If the determination unit determines that the mobile device supports wireless communication using the second communication method, the acquisition unit (S330, S345, S415, S430, S445, S460) causes the communication module to perform wireless communication with the mobile device using the second communication method and obtains position-related values related to the mobile device's location from the wireless communication signal with the mobile device using the second communication method, and if the determination unit determines that the mobile device does not support wireless communication using the second communication method, the acquisition unit (S330, S345, S415, S430, S445, S460) obtains position-related values related to the mobile device's location from the wireless communication signal with the mobile device using the first communication method, and The system is configured to include a determination unit (S340, S350, S420, S435, S450, S465) that determines the position of the mobile device relative to the vehicle or the area in which the mobile device is located, based on position-related values acquired by the acquisition unit. Furthermore, the position detection method according to this disclosure is a position detection method performed by a computer (1) for detecting the position of a portable device (9) relative to a vehicle (Hv) for vehicle control purposes , Using a communication module (2) installed in the vehicle , wireless communication is performed with a portable device using a first communication method (S300, S400), The communication module is configured to enable wireless communication with a mobile device using a second communication method different from the first communication method. Based on wireless communication with the mobile device using the first communication method, it is determined whether or not the mobile device supports wireless communication using the second communication method (S325, S410), If it is determined that the mobile device supports wireless communication using the second communication method, the communication module is instructed to perform wireless communication with the mobile device using the second communication method, and a location-related value related to the mobile device's position is obtained from the wireless communication signal with the mobile device using the second communication method. If it is determined that the mobile device does not support wireless communication using the second communication method, a location-related value related to the mobile device's position is obtained from the wireless communication signal with the mobile device using the first communication method (S330, S345, S415, S430, S445, S460), and, The system is configured to include determining the position of the mobile device relative to the vehicle or the area in which the mobile device is located based on the acquired position-related values (S340, S350, S420, S435, S450, S465). Furthermore, the computer according to this disclosure is a computer (1) that performs a process to detect the position of a portable device relative to a vehicle for vehicle control purposes , based on wireless communication signals when a communication module (2) installed in a vehicle (Hv) and a portable device (9) perform wireless communication, The communication module is configured to enable wireless communication with a mobile device using a second communication method different from the first communication method, in addition to the first communication method. Computers A process (S325, S410) that determines whether the mobile device supports wireless communication using the second communication method based on wireless communication with the mobile device using the first communication method, If it is determined that the mobile device supports wireless communication using the second communication method, the communication module is instructed to perform wireless communication with the mobile device using the second communication method, and a position-related value related to the mobile device's location is obtained from the wireless communication signal with the mobile device using the second co
