no. 1 Embodiment approach
[0014] Below, refer to Figure 1 ~ Figure 3 , the wireless communication system according to the first embodiment of the present invention will be described. In this embodiment, the wireless communication system is embodied as an electronic key system for a vehicle.
[0015] Such as figure 1 As shown, the electronic key system includes a vehicle 10 , a portable terminal 20 , and an electronic key 30 .
[0016] The portable terminal 20 may include a mobile phone capable of communicating with an information network (for example, the Internet), a so-called smartphone. The electronic key 30 can lock and unlock the vehicle doors by wirelessly communicating with the vehicle 10 . Hereinafter, configurations of the vehicle 10 , the portable terminal 20 , and the electronic key 30 will be specifically described.
[0017]
[0018] Vehicle 10 includes in-vehicle control device 11 , vehicle communication unit 12 , door lock device 13 , door handle switch 14 , vehicle state detection...
no. 2 Embodiment approach
[0056] Below, refer to Figure 4 , and the second embodiment of the present invention will be described. The electronic key system of the second embodiment differs from the above-mentioned first embodiment in that it is possible to display the processing method of the electronic key when the battery is exhausted on the mobile terminal. The electronic key system of the second embodiment includes figure 1 The electronic key system of the first embodiment shown has substantially the same configuration. Hereinafter, the electronic key system of the second embodiment will be described focusing on differences from the first embodiment.
[0057] Such as figure 1 As shown by the two-dot dash line, the electronic key 30 includes a mechanical key 37 and a transponder 38 . The mechanical key 37 can mechanically lock / unlock the vehicle doors when the battery of the electronic key 30 is exhausted. Specifically, the user takes out the mechanical key 37 stored in the electronic key 30 ....

Abstract
A wireless communication system including a portable device (20, 30) and a vehicle device (11) configured to transmit information including a vehicle state. The portable device (20, 30) includes a telecommunication unit (24) that obtains, through an information network, information including procedures that should be taken in accordance with the vehicle state or state of the portable device (20, 30), a display (27), and a control unit (21) that shows on the display (27) the vehicle state based on the information transmitted from the vehicle device (11) or the state of the portable device (20, 30) based on information of the portable device. When a measure should be taken in accordance with the vehicle state or the state of the portable device (20, 30), the control unit (21) shows on the display (27) the procedures included in the information obtained by telecommunication unit (24).
Description
technical field [0001] The present invention relates to a wireless communication system. Background technique [0002] Conventionally, as a kind of wireless communication system, an electronic key system capable of locking / unlocking vehicle doors and starting an engine through wireless communication between a vehicle and an electronic key can be mentioned. [0003] In order to improve the performance of the electronic key system, various improvements have been proposed. For example, in the electronic key system described in Japanese Patent Laid-Open No. 2005-9200, the vehicle wirelessly transmits an information signal including vehicle information such as the remaining amount of battery and gasoline to the electronic key. Once the electronic key receives the information signal from the vehicle, it identifies the vehicle information according to the signal, and displays the identified vehicle information on the display of the electronic key. Thus, the user can know the vehi...
