[0103] Figure 4 and Figure 5 is a schematic diagram showing a second embodiment of the electronic equipment (vehicle AV equipment) according to the present invention. In this embodiment, instead of predicting the engine stop of the vehicle from the pulse or signal input from the vehicle speed pulse acquisition part, the brake signal acquisition part, or the shift lever signal acquisition part as in the first embodiment, this embodiment An example is characterized in that an acceleration sensor and a vibration sensor are provided in an in-vehicle AV device, and engine stop of the vehicle is predicted from the acceleration or vibration of the vehicle. Since other structures are the same as those of the first embodiment, descriptions of the same parts are omitted by assigning the same reference numerals to the same parts.
[0104] First, refer to Figure 4 The overall structure of the vehicle-mounted AV equipment in this embodiment will be described.
[0105] Figure 4 is ...
