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.

1. An on-board recording system comprising: a control device that performs vehicle control associated with a first driving assist function optionally installed on a vehicle and a second driving assist function, different from the first driving assist function, that is not optionally installed on the vehicle; anda 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 vehicle behaviors is detected, the vehicle information being specified in advance for each of the pre-specified vehicle behaviors, and the vehicle information being obtained in a predetermined period corresponding to a time of detection of at least one of the vehicle behaviors, wherein:the control device includes a transmitting unit that outputs a transmission signal to the on-board network in a case where the first driving assist 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 determining unit determines whether the receiving unit has received the transmission signal from the control device,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 of the pre-specified vehicle behaviors, the recording area having a capacity that permits recording of the vehicle information for a pre-specified number of detections for each of the vehicle behaviors,the first vehicle behavior detecting unit detects, as a first vehicle behavior among the vehicle behaviors, activation of the first driving assist function,the second vehicle behavior detecting unit detects, as a second vehicle behavior among the vehicle behaviors, activation of the second driving assist function,the first recording processing unit records, when the first vehicle behavior detecting unit detects the first vehicle behavior, first vehicle information as the vehicle information corresponding to the first vehicle behavior in a first recording area of the vehicle information storage unit that corresponds to the first vehicle behavior,the second recording processing unit records, when the second vehicle behavior detecting unit detects the second vehicle behavior, second vehicle information as the vehicle information corresponding to the second vehicle behavior in at least one of the first recording area and a second recording area of the vehicle information storage unit that corresponds to the second vehicle behavior,the recording permitting unit permits the first recording processing unit to record the first vehicle information in the first recording area and permits the second recording processing unit to record the second vehicle information in the second recording area, andin a case where the received information indicates that the transmission signal has not been received and the first driving assist function is thus not installed on the vehicle, the recording permitting unit further permits the second recording processing unit to record the second vehicle information in the first recording area as well as the second recording area. 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 to the on-board network a control command associated with activation of the first driving assist function, 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 first driving assist 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, andthe 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, the recording permitting unit inhibits the second recording processing unit from recording the second vehicle information in the first recording area when the second vehicle behavior detecting unit detects the second vehicle behavior.
