Description

  The present invention relates to a drive recorder, an in-vehicle system including the drive recorder, and an in-vehicle device that controls the operation of the drive recorder.

  There is known a drive recorder capable of reliably maintaining appropriate evidence data when an accident or a crime occurs (see, for example, Patent Document 1).

JP 2009-93253 A

  The drive recorder records the video inside and outside the vehicle at the time of collision detection or at all times to record the evidence data indicating the situation at the time of unexpected accident or crime occurrence of the vehicle and the surroundings, and also records the sound It is desirable. On the other hand, the drive recorder has a risk that the privacy of the passenger cannot be protected because it records the conversation that the passenger is talking on the mobile phone or the like (hereinafter referred to as the contents of the call).

  In particular, in recent years, data recorded on a drive recorder is not only used as evidence when an accident occurs or when a crime occurs, but is sometimes viewed by passengers as having entertainment. In addition, even when an unexpected accident occurs, when browsing the data recorded at the time of the accident or crime, the data recorded at the time other than the accident or crime may be viewed by a third party. is there.

  However, from the viewpoint of privacy protection, if the passenger stops the recording by manual operation at the start of the call and forgets the operation to start the recording after the call ends, the data at the time of the accident or the crime will be stored thereafter. Not recorded.

  Thus, the conventional drive recorder has a problem that it is difficult to achieve both the recording of evidence data and the protection of privacy.

  The present invention has been made to solve the above-described problems, and an object thereof is to achieve both the recording of evidence data and the protection of privacy.

  A drive recorder according to the present invention is a drive recorder that captures and records at least one of the inside and outside of a vehicle and collects and records the sound in the vehicle interior, from an in-vehicle device existing in the vehicle interior to the vehicle interior. A communication unit that receives a call start signal indicating the start of a call of an existing mobile phone and a call end signal indicating a call end, a storage unit that stores voice in the vehicle interior as recording data, and a call start signal received by the communication unit And a control unit that controls recording of at least the call voice of the mobile phone in the storage unit of the voice in the vehicle interior based on the call end signal.

  According to the present invention, based on the call start signal indicating the start of the call of the mobile phone and the call end signal indicating the end of the call, the recording of at least the call sound of the mobile phone in the vehicle interior to the storage unit is controlled. As a result, it is possible to achieve both the recording of evidence data and the protection of privacy.
