A line-of-sight determining unit of a vehicle warning device determines the line-of-sight direction on the basis of a pupil on, or the direction of, a face included in a captured image of a driver. Adriving operation detection unit detects a demanded acceleration degree based on an accelerator operation performed by the driver, or a direction indicator switch operation for actuating a direction indicator of a vehicle. A control unit sets a warning timing on the basis of the output of the line-of-sight determining unit and the output of the driving operation detection unit. When a demanded acceleration degree equal to or greater than a prescribed acceleration degree, or a direction indicator switch operation, is detected, the control unit actuates an alarm at a timing that is delayed in relation to a warning timing.

    车辆用报警装置的视线判断部基于驾驶员的摄像图像中包含的脸部的朝向或者瞳孔来判断视线方向。驾驶操作检测部检测基于驾驶员的加速操作的要求加速度或者用于使车辆的方向指示灯动作的方向指示灯开关操作。控制部基于视线判断部的输出和驾驶操作检测部的输出设定报警时机。控制部,在检测到规定加速度以上的要求加速度或者方向指示灯开关操作的情况下,在比报警时机延迟的时机使报警器启动。
