Abstract
A control unit extracts stop position candidates P1 to Pn from the white line data and three-dimensional object data recognized and acquires their positions L1 to Ln, and sets, as a target stop position Lt, one of the stop position candidates P1 to Pn that is the closest to the braking distance Lb obtained based on the current braking operation quantity θp and vehicle speed V. The control unit subtracts a learning value LL from the target stop position Lt to calculate a corrected target stop position Ltc and sets a corrected braking operation quantity value θpc based on the corrected target stop position Ltc and vehicle speed V. When the absolute value |θp−θpc| of the difference between the braking operation quantity θp and the corrected braking operation quantity value θpc is within a preset range, the control unit executes braking control based on the corrected braking operation quantity value θpc.
