Abstract

One exemplary illustration of a vehicle video recording system may include an on-vehicle camera generating a video signal indicative of video data, at least one sensor, a RAM device and a controller communicatively coupled to the camera, the sensor and the RAM device. The controller may determine a recording duration based on sensor data received from the sensor. Further, the controller may store the video data and the associated sensor data to the RAM device for the recording duration. The controller may transfer video data and associated sensor data from the RAM device to a storage device in response to receiving a save-event signal from the sensor.

Claims

5. The on-vehicle video recording system of claim 2, wherein the storage device stores a reference lookup table including the restricted location and an associated disable signal for terminating a transfer of video data from the RAM device to the storage device when the vehicle is located in the restricted location.

6. The on-vehicle video recording system of claim 5, further comprising a human machine interface that is communicatively coupled to the controller and communicates a message indicating a status of the recording system, in response to the controller transmitting a status signal to the human machine interface.

7. The on-vehicle video recording system of claim 5, wherein the controller is configured to delete video data from the RAM device without saving the video data to the storage device.

8. The on-vehicle video recording system of claim 2, wherein the at least one sensor is an airbag sensor that generates the save-event signal in response to detecting an airbag deployment.

9. The on-vehicle video recording system of claim 2, wherein the at least one sensor is an accelerometer that generates the save-event signal in response to detecting at least one of:
