To provide an emergency call device for a vehicle, which can suppress a situation where an emergency call is not made when the vehicle rolls over.SOLUTION: An emergency call device for a vehicle mounted on the vehicle is comprised of: a wireless communication unit 131 which wirelessly transmits an emergency call signal to an outside of the vehicle; and a rollover prediction unit 132 that acquires a rollover-related quantity, which is a physical quantity for predicting a vehicle rollover, and predicts that the vehicle will roll over based on the acquired rollover-related quantity. The wireless communication unit 131 transmits an emergency call signal based on a fact that the rollover prediction unit 132 predicts that the vehicle will roll over. With this configuration, even if the wireless communication unit 131 becomes unusable after the vehicle rolls over, since the emergency call signal has already been transmitted, it is possible to suppress a situation where the emergency call signal is not transmitted when the vehicle rolls over.SELECTED DRAWING: Figure 3
【課題】車両が横転したときに、緊急通報されていないという事態を抑制できる緊急通報装置を提供する。【解決手段】車両に搭載される車両用緊急通報装置であって、車両の外部に緊急通報信号を無線送信する無線通信部131と、車両の横転を予測するための物理量である横転関連量を取得し、取得した横転関連量に基づいて、車両が横転することを予測する横転予測部132とを備え、無線通信部131は、横転予測部132が、車両が横転すると予測したことに基づいて緊急通報信号を送信する。この構成により、横転後に無線通信部131が使えなくなったとしても、すでに緊急通報信号を送信済みであるので、車両が横転したときに、緊急通報信号が送信されていないという事態を抑制できる。【選択図】図3
