The acquisition unit acquires data representing driving condition. The recording unit records the acquired data. The communication unit transmits the acquired data to the outside. The control unit controls the quality of the data to be transmitted based on the information received from the outside. ## Claims ### Claim 1 A drive recorder to be mounted on a vehicle, the drive recorder comprising: a memory including a program instruction; and a processor connected with the memory, wherein the processor is configured to execute the program instruction to: acquire data representing driving condition; record the acquired data; transmit the acquired data to outside; and control quality of the data to be transmitted based on information received from outside. ### Claim 2 (depends on 1) The drive recorder according to claim 1, further comprising a communication circuit that receives a predetermined command from the outside, wherein the processor is configured to control the quality of the data to be transmitted based on whether or not the command is received. ### Claim 3 (depends on 1) The drive recorder according to claim 1, further comprising a communication circuit that receives, from the outside, a command in which a temporal condition is set, wherein the processor is configured to determine whether or not the temporal condition is satisfied, and control the quality of the data to be transmitted based on a result of the determination. ### Claim 4 (depends on 1) The drive recorder according to claim 1, further comprising a communication circuit that receives, from the outside, a command in which a geographical condition is set, wherein the processor is configured to determine whether or not a position of the vehicle satisfies the geographical condition, and control the quality of the data to be transmitted based on a result of the determination. ### Claim 5 (depends on 1) The drive recorder according to claim 1, further comprising a communication circuit that receives, from the outside, a command in which a condition related to a feature of data is set, wherein the processor is configured to determine whether or not the data represents driving condition satisfying the condition, and control the quality of the data to be transmitted based on a result of the determination. ### Claim 6 (depends on 1) The drive recorder according to claim 1, further comprising a communication circuit that receives, from the outside, a command in which a search condition is set, wherein the processor is configured to search the recorded data for data satisfying the search condition, and control the quality of the data to be transmitted based on whether or not the data to be transmitted is searched data. ### Claim 7 (depends on 1) The drive recorder according to claim 1, further comprising: a first transmission buffer that records data representing driving condition and having first quality; and a second transmission buffer that records data representing driving condition and having second quality that is lower than the first quality, wherein the processor is configured to transmit the data recorded in the first transmission buffer in preference to the data recorded in the second transmission buffer. ### Claim 8 A driving condition management method to be executed by a drive recorder to be mounted on a vehicle, the method comprising: acquiring data representing driving condition; recording the acquired data; transmitting the acquired data to outside; and controlling quality of the data to be transmitted based on information received from outside. ### Claim 9 (depends on 8) The driving condition management method according to claim 8, wherein the controlling the quality includes controlling the quality of the data to be transmitted based on whether or not a predetermined command is received from the outside. ### Claim 10 (depends on 8) The driving condition management method according to claim 8, wherein the controlling the quality includes receiving, from the outside, a command in which a temporal condition is set, determining whether or not the temporal condition is satisfied, and controlling the quality of the data to be transmitted based on a result of the determination. ### Claim 11 (depends on 8) The driving condition management method according to claim 8, wherein the controlling the quality includes receiving, from the outside, a command in which a geographical condition is set, determining whether or not a position of the vehicle satisfies the geographical condition, and controlling the quality of the data to be transmitted based on a result of the determination. ### Claim 12 (depends on 8) The driving condition management method according to claim 8, wherein the controlling the quality includes receiving, from the outside, a command in which a condition related to a feature of data is set, determining whether or not the data represents driving condition satisfying the condition, and controlling the quality of the data to be transmitted based on a result of the determination. ### Claim 13 (depends on 8) The driving condition management method according to claim 8, wherein the controlling the quality includes receiving, from the outside, a command in which a search condition is set, searching the recorded data for data satisfying the search condition, and controlling the quality of the data to be transmitted based on whether or not the data to be transmitted is searched data. ### Claim 14 (depends on 8) The driving condition management method according to claim 8, wherein the transmitting the data to the outside includes recording data representing driving condition and having first quality in a first transmission buffer, recording data representing driving condition and having second quality in a second transmission buffer, the second quality being lower than the first quality, and transmitting the data recorded in the first transmission buffer in preference to the data recorded in the second transmission buffer. ### Claim 15 A non-transitory computer readable medium storing a program comprising instructions for causing a computer, to be mounted on a vehicle, to function as: an acquisition unit that acquires data representing driving condition; a recording unit that records the acquired data; a communication unit that transmits the acquired data to outside; and a control unit that controls quality of the data to be transmitted based on information received from outside.
