Claim 8:
9. The map information correction apparatus according to claim 8, wherein
the error calculation circuitry calculates a position information error variance value, a speed information error variance value, and a time information error variance value on the basis of differences between information included in the high-priority own mobile object surrounding information feature points and information included in the high-priority map information feature points corresponding to the information, the position information error variance value being a variance value of errors in the position information on the map information feature points, the speed information error variance value being a variance value of errors in the speed information on the map information feature points, the time information error variance value being a variance value of errors in the time information on the map information feature points, and the error calculation circuitry identifies, as the error, the average value of the information on the feature points having the smallest variance among the position information error variance value, the speed information error variance value, and the time information error variance value.
