PURPOSE:To prevent the error in judgment of lateral stripe, by excluding the judgment by a stripe-reaping sensor A and a stripe-reaping sensor B from counting when the distance of the ON-state is longer than the distance between the stripes. CONSTITUTION:When a stripe-reaping sensor A is thrust into a hill 11 to fall the hill and continues the state of ON over about 30cm, both of the stripe counter and lateral counter are omitted from counting. When a stripe-reaping sensor B is thrust into a hill 11 to fall the hill and continues the state of ON over about 30cm, both of the stripe counter and lateral counter are omitted from counting.
