Abstract

A vehicle drive recorder is provided for recording a signal onto a hard disk, such signal obtained while vehicle is in operation. The recorder inhibits data recording upon receipt of an inhibit signal. Inhibit canceling signal is also available.

Claims

1. A vehicle recorder comprising:

an input, receiving information detected by a sensor; and

a storage controller, controlling a recording of said signal from said input;

wherein said storage controller capable of generating write inhibit signal.

2. A recorder as in claim 1, wherein said recorder stops recording in response to said write inhibit signal.

3. A recorder as in claim 2, wherein said write inhibit signal is generated in response to a vehicle disorder signal.

4. A recorder comprising:

an input, receiving information detected by a sensor; and

a storage controller, controlling a recording of said signal from said input;

wherein said storage controller generates write inhibit signal in response to an airbag activation signal.

5. A recorder as in claim 4, wherein said recorder stops recording in response to said write inhibit signal.

6. A recorder as in claim 4, wherein said write inhibit signal is a write protection signal.

7. A recorder as in claim 4, wherein said recorder restarts recording in response to a cancel signal.

8. A recorder as in claim 7, wherein said cancel signal is issued in response to an input.

9. A recorder as in claim 4, wherein said storage controller is connected to a switch that activates in response to said write inhibit signal.

10. A recorder as in claim 4, wherein said storage controller is connected to a switch that opens in response to said write inhibit signal.

11. A recorder, recording a signal obtained during vehicle is in motion onto a hard disk, comprising:

an input, receiving a signal detected by a sensor mounted in a vehicle;

a temporary storage, temporarily storing a signal transmitted via said input;

a timer, counting time; and

a storage controller, storing said signal and a time stamp onto said hard disk;

wherein said storage controller includes a write protection signal generator for inhibiting recording of said information,

12. A recorder as in claim 11, wherein said write protection signal generator generates said signal in response to a vehicle disorder signal.
