An arrangement determines a gradient signal in a vehicle. The arrangement has: a position capture device that determines a vehicle position at a first and second time and ascertains therefrom a distance traveled as a motion vector, and a laser distance sensor on the vehicle front at an angle to a vehicle longitudinal axis and configured to emit a laser beam in a direction of a first measuring point in front of the vehicle at the first and second time, and a length sensor to ascertain the length of the laser beam and its associated vector at the first and second time, and at least one detection device to ascertain a differential vector from the motion vector and the ascertained vectors and to form a gradient signal therefrom.

A vehicle control device controls a vehicle provided with a transmission having a direct gear and normal gears including an overdrive gear having a lower gear ratio than the direct gear. The device includes a travel segment determination unit which determines a forward travel segment having a different road slope from a current travel segment, a current gear position selection unit that selects a current gear position based on a travel resistance of the vehicle, a forward gear position selection unit that selects a forward gear position based on a travel resistance in the forward travel segment, and a shift control unit that selects whether or not to upshift the transmission based on a situation until the vehicle reaches the forward travel segment, when an upshift to the overdrive gear is newly selected in a case where the current gear position and the forward gear position are the direct gear.

A vehicle control device in an embodiment includes a recognition unit that recognizes a surrounding situation of a vehicle and a driving control unit that controls one or both of steering and acceleration or deceleration of the vehicle on the basis of the surrounding situation recognized by the recognition unit, and in a case where the vehicle merges into a second lane from a first lane in which the vehicle travels, and a section of the second lane before merging recognized by the recognition unit is downhill, the driving control unit makes a speed or acceleration of the vehicle higher than in a case where the section before merging is not downhill.
