A vehicle gear control method includes acquiring a driving scene image while a vehicle is driving, and performing image recognition on the acquired driving scene image to obtain a driving scene label including at least one of a road attribute label, a traffic attribute label, or an environment attribute label. The method further includes acquiring driving status data and driving behavior data corresponding to the vehicle. The driving status data indicates at least one of vehicle speed and vehicle acceleration and the driving behavior data indicates at least one of a brake control input, an accelerator control input, or a throttle opening degree. The method further includes determining a gear shifting mode based on the driving status data, the driving behavior data, and the driving scene label. The gear shifting mode controls the vehicle to drive according to a corresponding gear at a corresponding gear shifting time.

A method in a control arrangement of a vehicle and a control arrangement for a vehicle for downshifting gears in an uphill slope are presented. The method comprises, when the vehicle is travelling in an uphill slope using an initial gear of the vehicle's automated manual transmission gearbox: simulating at least one speed profile for a downshift to, and a usage of, at least one gear; determining that a minimal speed of each one of the at least one simulated speed profile has a value indicating that the actual speed of the vehicle will be less than or equal to zero in the uphill slope; opening a clutch before is reduced to a value less than zero; activating at least one vehicle brake; shifting vehicle's automated manual transmission gearbox to a start gear; closing the clutch; and deactivating the at least one vehicle brake.

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.
