The drive assisting device divides the drive assisting information for every type (static information and dynamic information at the intersection), and sequentially performs the calculation. ## Claims ### Claim 1 A drive assisting system, wherein the drive assisting system calculates drive assisting information associated with an intersection required for drive assisting control to an assisting vehicle based on intersection information of the intersection, and calculates the drive assisting information according to type of drive assisting information when performing the drive assisting control associated with the intersection based on the drive assisting information, the drive assisting information being divided to essential drive assisting information required for execution of the drive assisting control regardless of type of assisting content of the drive assisting control, and unique drive assisting information required for execution of the drive assisting control corresponding to the assisting content of the drive assisting control requested for execution. ### Claim 2 (depends on 1) The drive assisting system according to claim 1, wherein the drive assisting information is divided for each type and sequentially calculated. ### Claim 3 (depends on 1) The drive assisting system according to claim 1, wherein the essential drive assisting information is divided to static essential drive assisting information based on static information at the intersection and dynamic essential drive assisting information that is remaining essential drive assisting information excluding the static essential drive assisting information, and calculation of the drive assisting information is performed separately between the static essential drive assisting information, and the dynamic essential drive assisting information and the unique drive assisting information. ### Claim 4 (canceled) ### Claim 5 (canceled) ### Claim 6 (depends on 1) The drive assisting system according to claim 1, wherein the intersection is an immediate intersection in an advancing direction of a road on which the assisting vehicle is traveling. ### Claim 7 (depends on 6) The drive assisting system according to claim 6, wherein when performing the drive assisting control to a plurality of intersections including the immediate intersection, drive assisting information associated with a non-immediate intersection excluding the immediate intersection among the plurality of intersections has simple drive assisting information calculated based on intersection information of the non-immediate intersection with respect to the drive assisting information associated with the immediate intersection. ### Claim 8 (depends on 7) The drive assisting system according to claim 7, wherein the simple drive assisting information has an amount of information suppressed compared to the drive assisting information required for the drive assisting control associated with the non-immediate intersection, and information required for the drive assisting control associated with the non-immediate intersection is calculated at a stage before passing the immediate intersection. ### Claim 9 (depends on 7) The drive assisting system according to claim 7, wherein the simple drive assisting information has an amount of information suppressed compared to the drive assisting information required for the drive assisting control associated with the non-immediate intersection, and static information is calculated at the non-immediate intersection. ### Claim 10 (depends on 7) The drive assisting system according to claim 7, wherein the drive assisting control associated with the immediate intersection is executed based on the drive assisting information associated with the immediate intersection and the simple drive assisting information associated with the non-immediate intersection. ### Claim 11 (depends on 7) The drive assisting system according to claim 7, wherein when the assisting vehicle has passed the immediate intersection, the drive assisting control associated with the non-immediate intersection is executed based on the simple drive assisting information. ### Claim 12 (depends on 7) The drive assisting system according to claim 7, wherein when the assisting vehicle has passed the immediate intersection, a non-immediate intersection closest from the assisting vehicle in an exit way from the immediate intersection is assumed as a new immediate intersection. ### Claim 13 (depends on 7) The drive assisting system according to claim 7, wherein number of non-immediate intersections in which calculation processing of the simple drive assisting information is executed at same timing is changed according to a calculation processing ability of the assisting vehicle. ### Claim 14 (depends on 2) The drive assisting system according to claim 2, wherein the essential drive assisting information is divided to static essential drive assisting information based on static information at the intersection and dynamic essential drive assisting information that is remaining essential drive assisting information excluding the static essential drive assisting information, and calculation of the drive assisting information is performed separately between the static essential drive assisting information, and the dynamic essential drive assisting information and the unique drive assisting information. ### Claim 15 (depends on 2) The drive assisting system according to claim 2, wherein the intersection is an immediate intersection in an advancing direction of a road on which the assisting vehicle is traveling. ### Claim 16 (depends on 3) The drive assisting system according to claim 3, wherein the intersection is an immediate intersection in an advancing direction of a road on which the assisting vehicle is traveling. ### Claim 17 (depends on 8) The drive assisting system according to claim 8, wherein the drive assisting control associated with the immediate intersection is executed based on the drive assisting information associated with the immediate intersection and the simple drive assisting information associated with the non-immediate intersection. ### Claim 18 (depends on 9) The drive assisting system according to claim 9, wherein the drive assisting control associated with the immediate intersection is executed based on the drive assisting information associated with the immediate intersection and the simple drive assisting information associated with the non-immediate intersection. ### Claim 19 (depends on 8) The drive assisting system according to claim 8, wherein when the assisting vehicle has passed the immediate intersection, the drive assisting control associated with the non-immediate intersection is executed based on the simple drive assisting information. ### Claim 20 (depends on 9) The drive assisting system according to claim 9, wherein when the assisting vehicle has passed the immediate intersection, the drive assisting control associated with the non-immediate intersection is executed based on the simple drive assisting information. ### Claim 21 (depends on 10) The drive assisting system according to claim 10, wherein when the assisting vehicle has passed the immediate intersection, the drive assisting control associated with the non-immediate intersection is executed based on the simple drive assisting information. ### Claim 22 (depends on 8) The drive assisting system according to claim 8, wherein when the assisting vehicle has passed the immediate intersection, a non-immediate intersection closest from the assisting vehicle in an exit way from the immediate intersection is assumed as a new immediate intersection.
