Embodiment Construction
[0033] [1. Communication processing between the vehicle and the mobile terminal]
[0034] refer to figure 1 Next, communication processing performed between the vehicle 1 on which the vehicle control system 10 is mounted and the mobile terminal 100 owned by the user of the vehicle 1 will be described. The vehicle control system 10 is constituted by an ECU (Electronic Control Unit: Electronic Control Unit) as will be described later.
[0035] The vehicle 1 is equipped with a narrow-area wireless communication device 60 for performing narrow-area wireless communication based on BLE (Bluetooth Low Energy: Bluetooth Low Energy, Bluetooth is a registered trademark) and UWB (Ultra Wide Band: Ultra Wideband), and a narrow-area wireless communication device 60 for performing narrow-area wireless communication based on public lines. Wide area wireless communication device 50 for wide area wireless communication. The wide area wireless communication device 50 is, for example, a TCU (T...

The invention provides a vehicle control system and a vehicle control method. Power consumption of communication in a vehicle can be suppressed. The vehicle control system (10) is provided with: a first position measurement unit (21) that measures the position of a portable terminal by means of a first position measurement process; a second position measurement unit (23) that measures the position of the portable terminal by wireless communication in a second position measurement process in which power consumption in the vehicle is less than that in the first position measurement process; and a position measurement control unit (24) that, using a first region outside the vehicle (1) and a second region outside the first region as monitoring regions, continues the measurement of the position of the portable terminal by the second position measurement unit (23) when the position of the portable terminal measured by the second position measurement unit (23) is within the second region, and when the position of the portable terminal measured by the second position measurement unit (23) is within the first region, switches the position of the portable terminal to the measurement of the position of the portable terminal by the first position measurement unit (21).
Description
technical field [0001] The invention relates to a vehicle control system and a vehicle control method. Background technique [0002] Conventionally, a vehicle control system has been proposed in which a vehicle is equipped with a security device and an indoor reader / writer, so that the vehicle can be operated by a vehicle key and a portable terminal such as a smartphone (for example, refer to Patent Document 1). In the vehicle control system described above, the security device allows the vehicle key to unlock and unlock the door lock when the authentication of the vehicle key is successful in the communication area outside the vehicle. In addition, the security device allows the vehicle key to start the engine when the authentication of the vehicle key is successful within the communication area in the vehicle. [0003] In addition, when the indoor reader / writer successfully authenticates with the portable terminal brought into the car through NFC (Near Field Communication...
