1. A vehicle detection information sharing system comprising:
a detection information acquiring unit configured to i) communicate with a first vehicle traveling on a road and ii) acquire, from the first vehicle, detection information on an obstacle detected by the first vehicle;
a vehicle information acquiring unit configured to i) communicate with a second vehicle which is traveling on the road and within an area including the obstacle and ii) acquire, from the second vehicle, vehicle information of the second vehicle;
a risk degree calculator configured to calculate a risk degree between the second vehicle and the obstacle based on i) the detection information on the obstacle from the first vehicle and ii) the vehicle information of the second vehicle, the risk degree being a degree of risk that arises between the second vehicle and the obstacle, the vehicle information of the second vehicle indicating whether a third vehicle is present around the second vehicle; and
an information transmitter configured to transmit, to the second vehicle, one of risk avoidance instructions corresponding to the risk degree between the second vehicle and the obstacle, and control the second vehicle to execute the one of the risk avoidance instructions to avoid the risk that arises between the second vehicle and the obstacle,
wherein the risk avoidance instructions include (1) a first instruction to force the second vehicle to drive a brake of the second vehicle to stop the second vehicle, and (2) a second instruction to control a display of the second vehicle to display a message,
wherein the risk degree calculator is configured to calculate the risk degree i) as a first predetermined value based on the vehicle information of the second vehicle indicating that the third vehicle is present around the second vehicle and ii) as a second predetermined value based on the vehicle information of the second vehicle indicating that the third vehicle is not present around the second vehicle, the second predetermined value being lower than the first predetermined value,
wherein the information transmitter is configured to (1) control the second vehicle by transmitting the first instruction to the second vehicle as the one of the risk avoidance instructions when the risk degree is the first predetermined value, and (2) control the second vehicle by transmitting the second instruction to the second vehicle as the one of the risk avoidance instructions when the risk degree is the second predetermined value,
wherein the second vehicle comprises a plurality of second vehicles,
wherein the vehicle information acquiring unit is configured to acquire corresponding vehicle information on each of the second vehicles,
wherein the risk degree calculator is configured to calculate risk degrees respectively for the second vehicles on a basis of the detection information and the corresponding vehicle information, each of the risk degrees being a degree of risk that arises between the each of the second vehicles and the obstacle, and
wherein the information transmitter is configured to transmit risk avoidance information to the second vehicles in a descending order of the risk degrees such that the risk avoidance information is transmitted to one of the second vehicles before another one of the second vehicles based on determining that the one of the second vehicles has a higher degree of risk than the another one of the second vehicles has.
