Abstract: A vehicle control device includes a braking unit 15 for braking a vehicle, an obstacle detection sensor for detecting an obstacle in front of the vehicle, a braking control unit for controlling a braking of the vehicle by the braking unit on the basis of a detection condition of the obstacle, an acquisition unit for acquiring position information indicating a position of the vehicle, and a storage control unit for storing, in a storage unit, braking history information that includes the position information acquired when the braking of the vehicle is performed by the braking unit under control of the braking control unit.

Abstract: A driving assistance device (30) that has: an information acquisition unit (31) that acquires the relative speed of a vehicle ahead and the inter-vehicle distance to the vehicle ahead; a table (33) in which degrees of urgency that correspond to relative speeds and inter-vehicle distances have been pre-stored; and an ACC control unit (32) that reads out, from the table (33), a degree of urgency (x) that corresponds to the relative speed and inter-vehicle distance acquired by the information acquisition unit (31), finds a target acceleration/deceleration that has a slope (y) that is based on the degree of urgency (x) that was read out, and outputs the found target acceleration/deceleration as a control signal for controlling break pressure.

Abstract: This cruise control device enables more accurate prediction of running resistance and prevents worsening of fuel economy. In this device, a coasting prediction unit (12c) of an automatic cruise control device (12), which is for performing cruise control of the vehicle (1) on the basis of a resistance coefficient, predicts, on the basis of the resistance coefficient, the change in vehicle speed if the vehicle (1) were to coast; if the vehicle (1) does coast, a vehicle information acquisition unit (12b) acquires information about the detected vehicle speed; and a running resistance updating unit (12f) updates the value of the resistance coefficient on the basis of the information about the change in vehicle speed predicted by the coasting prediction unit (12c) and information about the vehicle speed acquired by the vehicle information acquisition unit (12b).
