Patent ID: 8483928

Claim:
A follow-up run control device controlling a running state of a vehicle in a state where peripheral vehicles running before or behind the vehicle exist, comprising: determination means for determining the peripheral vehicles having an influence on a run control of the vehicle, wherein the peripheral vehicles performing inter-vehicle communication with the vehicle are communicating peripheral vehicles, and wherein at least one of the peripheral vehicles running in a forefront among the communicating peripheral vehicles in a same lane has an influence on a run control of the vehicle; deviation acquiring means for acquiring information regarding a deviation between a relative positional relation and a target relative positional relation of the vehicle and the peripheral vehicles with respect to preceding vehicles running just before; and follow-up control amount calculating means for calculating a follow-up control amount of the vehicle to control the running state of the vehicle on the basis of the information regarding the deviations of a plurality of vehicles acquired by the deviation acquiring means, wherein when m (where m=2, 3, . . . ) peripheral vehicles exist, the follow-up control amount u of the vehicle calculated by the follow-up control amount calculating means is expressed by the following expression, u = k 1 ⁢ D 1 + c 1 ⁢ D 1 ′ + k 2 ⁡ ( D 1 + D 2 ) + c 2 ⁡ ( D 1 ′ + D 2 ′ ) + … + k m ⁡ ( D 1 + D 2 + … + D m ) + c m ⁡ ( D 1 ′ + D 2 ′ + … + D m ′ ) where D 1 represents the deviation between the relative positional relation and the target relative positional relation of the vehicle with respect to the preceding vehicle thereof, D 1 ′ represents the temporal differentiation of the deviation D 1 , D n represents the deviation between the relative positional relation and the target relative positional relation of the (n−1)-th peripheral vehicle before the vehicle with respect to the preceding vehicle thereof, D n ′ represents the temporal differentiation of the deviation D n , and k 1 to k m and c 1 to c m are constants.
