Abstract

There is provided a driving information recording apparatus having high versatility in which even in the event there is a request for an additional trigger, the requested trigger can be added in a simple fashion. When an ON/OFF port admits the input of a signal from an airbag ECU, a primary CPU conducts a control such that recording in a CF card is implemented using the signal inputted as a trigger. In particular, since the ON/OFF port is made to admit the input of a signal from another vehicle state detecting unit which is different from a detecting unit for detecting that a vehicle is put in a predetermined state, a drive recorder does not have to be re-fabricated from the beginning.

Claims

1. A driving information recording apparatus comprising a unit for storing cyclically driving information on the driving of a vehicle in a memory unit and a unit for recording the driving information stored in the memory unit in a recording medium using as a trigger a signal that is inputted thereinto from a detecting unit for detecting that the vehicle is put in a predetermined state, the driving information recording apparatus further comprising:

an input unit which is originally provided and into which a signal from a vehicle state detecting unit that is different from the detecting unit can be inputted; and

a control unit for conducting a control such that the driving information stored in the memory unit is recorded in the recording medium using as a trigger a signal inputted from the input unit.

2. The driving information recording apparatus of claim 1, wherein a signal indicating a deployment of an airbag can be inputted into the input unit from an airbag control unit for having the airbag deployed when the vehicle is involved in a collision.

3. The driving information recording apparatus of claim 2, wherein in the control unit, a timing when to monitor whether or not there exists a signal indicating a deployment of an airbag can be set to occur earlier than a monitoring timing which is set originally.

4. The driving information recording apparatus of claim 1, wherein a signal raising an alarm can be inputted into the input unit from a security control unit for raising the alarm when detecting an attempt to steal the vehicle.

5. The driving information recording apparatus of claim 4, wherein the control unit monitors whether or not there exists a signal raising the alarm when the driving of the vehicle is stopped while ignoring the monitor of other unnecessary triggers when the driving of the vehicle is stopped.

6. The driving information recording apparatus of claim 4, wherein the driving information recording apparatus is constituted so as to be started up by receiving a signal indicating an entry into a theft monitoring state, outputted from the security control unit, and

the control unit monitors whether or not there exists an alarm signal in the driving information recording apparatus running after being started up by the signal, and conducts a control such that the driving information stored in the memory unit is recorded using the alarm signal as a trigger.

7. The driving information recording apparatus of claim 4, wherein in a case where a signal indicating an entry into a theft monitoring state, outputted from the security control unit, is inputted into the driving information recording apparatus within a predetermined length of time after an accessory signal of the vehicle is brought into an OFF state,

the control unit keeps the driving information recording apparatus running, monitors whether or not there exists an alarm signal in the running state, and conducts a control such that the driving information stored in the memory unit is recorded using the alarm signal as a trigger.

8. The driving information recording apparatus of claim 4, wherein the control unit and the security control unit are adapted so as to be installable in an electrically connected state or non-connected state, the control unit having a function of determining whether or not being in the connected state,

wherein the control unit being in the connected state with the security control unit, after an accessory signal of the vehicle is brought into an OFF state, keeps the driving information recording apparatus running, monitors whether or not there exists an alarm signal in the running state, and conducts a control such that the driving information stored in the memory unit is recorded using the alarm signal as a trigger.

9. The driving information recording apparatus of claim 6, further comprising a storage medium therein,

wherein the control unit controls such that the driving information stored in the memory unit using the alarm signal as a trigger is recorded in the storage medium disposed inside of the driving information recording apparatus without being recorded in the recording medium.

10. The driving information recording apparatus of claim 9, wherein the control unit conducts a control such that the driving information stored in the storage medium is recorded in the recording medium by a predetermined operation.

11. The driving information recording apparatus of claim 6, wherein further comprising a secondary battery therein, wherein the driving information recording apparatus is kept running by the secondary battery.
