VEHICLE CONTROL SYSTEM AND VEHICLE CONTROL UNIT
To ensure convenience for a user and reduce power consumption of a vehicle control unit.SOLUTION: A vehicle control system 101 comprises: a vehicle control unit 10 that is mounted on a vehicle 1; and an electronic key 20 and a smartphone 30 that are carried by a user of the vehicle 1 and wirelessly communicate with the vehicle control unit 10. When two-way communication with the electronic key 20 is established, and authentication of the electronic key 20 is successful, the vehicle control unit 10 executes reservation control for the vehicle 1. The vehicle control unit 10 includes a first searching unit 11a that searches for the electronic key 20 by performing polling of an LF signal, and a second searching unit 11b that searches for the smartphone 30 by performing polling of a BLE signal; when searching for the electronic key 20 with the first searching unit 11a and searching for the smartphone 30 with the second searching unit 11b, the vehicle control unit performs polling of the LF signal for a long period before the establishment of the two-way communication with the smartphone 30, and performs polling of the LF signal for a short period after the establishment of the two-way communication with the smartphone 30.SELECTED DRAWING: Figure 1
【課題】利用者の利便性を確保し、車両制御装置の消費電力を低減する。【解決手段】車両制御システム１０１は、車両１に搭載された車両制御装置１０と、車両１の利用者に携帯され、車両制御装置１０と無線通信する電子キー２０およびスマートフォン３０を備える。車両制御装置１０は、電子キー２０との相互通信が確立し、かつ電子キー２０の認証が成功した場合に、車両１の予約制御を実行する。また、車両制御装置１０は、ＬＦ信号のポーリングを行って電子キー２０を探索する第１探索部１１ａと、ＢＬＥ信号のポーリングを行ってスマートフォン３０を探索する第２探索部１１ｂとを有し、第１探索部１１ａで電子キー２０を探索しかつ第２探索部１１ｂでスマートフォン３０を探索する場合において、スマートフォン３０との相互通信確立前は、ＬＦ信号を長周期でポーリングし、スマートフォン３０との相互通信確立後は、ＬＦ信号を短周期でポーリングする。【選択図】図１
