Abstract

An on-board recording system includes a control device and a recording device. The control device includes a transmitting unit that outputs a transmission signal when a driving assistance function is installed on the vehicle, and the recording device includes a receiving unit, a storage unit including a first area and a second area, a first vehicle behavior detecting unit, a second vehicle behavior detecting unit, a first recording processing unit, a second recording processing unit, and a recording permitting unit that permits the first recording processing unit to record the first vehicle information in the first area, and inhibits the second recording processing unit from recording the second vehicle information in the first area, when the transmission signal has been received, and permits the second recording processing unit to record the second vehicle information in the first area when the transmission signal has not been received.

Claims

1. An on-board recording system comprising

a control device that performs vehicle control including control associated with a driving assistance function selectively installed on a vehicle, and

a recording device communicably connected to the control device via an on-board network, the recording device being configured to record vehicle information representing a state of the vehicle when any of pre-specified types of vehicle behaviors is detected, the vehicle information being specified in advance for each of the pre-specified types of vehicle behaviors, the vehicle information being obtained in a predetermined period corresponding to a time of detection at which the vehicle behavior is detected, wherein

the control device includes a transmitting unit that outputs a transmission signal to the on-board network in a case where the driving assistance function is installed on the vehicle,

the recording device includes a receiving unit, a determining unit, a received information storage unit, a vehicle information storage unit, a first vehicle behavior detecting unit, a second vehicle behavior detecting unit, a first recording processing unit, a second recording processing unit, and a recording permitting unit,

the receiving unit receives the transmission signal,

the determining unit determines whether the receiving unit has received the transmission signal,

the received information storage unit stores a result of determination by the determining unit, as received information,

the vehicle information storage unit includes a recording area set for each type of the vehicle behaviors, the recording area having a capacity that permits recording of the vehicle information for a pre-specified number of detection for each type of the vehicle behaviors,

the first vehicle behavior detecting unit detects a first vehicle behavior as activation of the driving assistance function, among the vehicle behaviors,

the second vehicle behavior detecting unit detects a second vehicle behavior of a different type from the first vehicle behavior, among the vehicle behaviors,

the first recording processing unit records first vehicle information as the vehicle information corresponding to the first vehicle behavior, in a first area as the recording area corresponding to the first vehicle behavior, when the first vehicle behavior detecting unit detects the first vehicle behavior,

the second recording processing unit records second vehicle information as the vehicle information corresponding to the second vehicle behavior, in at least one of the first area, and a second area as the recording area corresponding to the second vehicle behavior, when the second vehicle behavior detecting unit detects the second vehicle behavior,

the recording permitting unit permits the first recording processing unit to record the first vehicle information in the first area, and permits the second recording processing unit to record the second vehicle information in the second area, while inhibiting the second recording processing unit from recording the second vehicle information in the first area, when the received information indicates that the transmission signal has been received, and the recording permitting unit permits the second recording processing unit to record the second vehicle information in the first area and the second area, when the received information indicates that the transmission signal has not been received.

2. The on-board recording system according to claim 1, wherein

the transmitting unit outputs the transmission signal to the on-board network when the vehicle is started.

3. The on-board recording system according to claim 1, wherein

the control device includes a control command creating unit that outputs a control command associated with activation of the driving assistance function, to the on-board network, and the transmission signal comprises the control command.

4. The on-board recording system according to claim 1, wherein

the on-board network comprises a CAN, and the transmission signal comprises a CAN frame having a CAN-ID that is uniquely given to the driving assistance function.

5. The on-board recording system according to claim 1, wherein

when the determining unit determines that the receiving unit has received the transmission signal, the determining unit does not subsequently determine whether the receiving unit has received the transmission signal.

6. The on-board recording system according to claim 1, wherein

the transmitting unit repeatedly transmits the transmission signal, during a period from starting to stop of the vehicle, and

the determining unit repeatedly determines whether the receiving unit has received the transmission signal, during the period from starting to stop of the vehicle.

7. The on-board recording system according to claim 1, wherein

even in the case where the received information indicates that the transmission signal has not been received when the second vehicle behavior detecting unit detects the second vehicle behavior, the recording permitting unit inhibits the second recording processing unit from recording the second vehicle information in the first area, in the case where the received information indicates that the transmission signal has been received, when the second recording processing unit records the second vehicle information in the vehicle information storage unit according to the detection.

8. The on-board recording system according to claim 1, wherein

the control device includes a first control device that performs control associated with a first driving assistance function as the driving assistance function, and a second control device that performs control associated with a second driving assistance function as the driving assistance function,

the first vehicle behavior is activation of the first driving assistance function,

the second vehicle behavior is activation of the second driving assistance function,

when the received information indicates that both of the transmission signal corresponding to the first driving assistance function and the transmission signal corresponding to the second driving assistance function have been received, the recording permitting unit permits the first recording processing unit to record the first vehicle information in the first area, and permits the second recording processing unit to record the second vehicle information in the second area, while inhibiting the second recording processing unit from recording the second vehicle information in the first area, and

when the received information indicates that the transmission signal corresponding to the first driving assistance function has not been received, and the transmission signal corresponding to the second driving assistance function has been received, the recording permitting unit permits the second recording processing unit to record the second vehicle information in the first area and the second area.
