The disclosure relates to a dual-speed final drive control method and terminal device, and a storage medium. The method includes: when an absolute value of a gradient value of a road ahead is greater than a gradient threshold, determining, according to the gradient value, whether the road ahead is an uphill section or a downhill section, thereby controlling all gears of a transmission to correspond to a higher final drive ratio or a lower final drive ratio in the dual-speed final drive. The disclosure can make use of the dual-speed-ratio final drive to the greatest extent to improve the economy in energy consumption of the entire vehicle.

Disclosed is a method for determining a position of a motor vehicle by means of a location device of the motor vehicle. First, a first position (x.sub.1) related to an installation point of the location device in the motor vehicle is determined. In order to determine a position suitable for controlling the motor vehicle, with reference to the said first position (x.sub.1) a second position (x.sub.2) related to a center of gravity of the vehicle is determined, in that the first position (x.sub.1) is offset by a distance (a) between the said installation point of the location device and the center of gravity of the vehicle.

A shift control apparatus and a method for a vehicle are provided. The shift control apparatus and the method for a vehicle that can control gear shifts by detecting a slope ahead based on road information are provided. The shift control apparatus for a vehicle may include: an engine; a transmission configured to receive power from the engine; and a controller configured to check an effective sloping point based on road information, to calculate a target gear ratio based on a first engine torque at a location of the vehicle and a gear ratio of the transmission when the effective sloping point is reached within a predetermined amount of time, to set a target gear position based on the target gear ratio, and to control the transmission based on the target gear position.

Techniques related to vehicle operation. A processor determines that at least one condition is met related to a vehicle. In response to the at least one condition being met, the processor generates a natural language output having a query. The processor determines that an affirmative response to the query is received and causes a downshift of a transmission of the vehicle in response to the affirmative response.

A manual mode training system for a vehicle having a manual transmission or a manual mode transmission controlled by a paddle shifter. The system includes a sensor to obtain force and position information from a foot pedal of the vehicle, and a processor to receive the information. Based on the information, the processor may predict an intended vehicle response, determine an appropriate gear to achieve the intended vehicle response, and notify a driver, through a haptic feedback mechanism, how to shift the transmission of the vehicle to reach the appropriate gear. A corresponding method is also disclosed and claimed herein.

A human-powered vehicle control device controls the transmission that changes the transmission ratio of a human-powered vehicle. The control device includes an electronic controller that switches between a first control state for controlling the transmission to change the transmission ratio in accordance with a first prescribed set of conditions, and a second control state for controlling the transmission to suppress the change of the transmission ratio as compared with if the electronic controller is in the first control state, in accordance with at least one of the motion state of the body of the human-powered vehicle, the steering state of the human-powered vehicle, the surface conditions of a travel path on which the human-powered vehicle travels, and a pedaling preparation state related to the pedals of the human-powered vehicle.

A road information acquisition unit (12a) acquires information about the road in a prescribed segment in front, a vehicle information acquisition unit (12b) acquires information about the vehicle (1), a velocity prediction unit (12c) predicts, on the basis of the road information and the information about the vehicle (1), the changes in the vehicle velocity that would be brought about in the prescribed segment in the case of travelling the prescribed segment in a first gear, and a shift control unit (12d) which maintains the first gear if the condition is satisfied that the predicted vehicle velocity exhibits a minimum value other than at the ends of the prescribed segment and the minimum value is greater than the delay speed, which is set to a value less than a predetermined velocity set as the velocity that would result from downshifting.

A shifting control method for controlling a speed change of a vehicle in a downhill section may include collecting, by a forward road grade information collection device, information on a downhill grade which is present ahead of a vehicle, before a vehicle enters a downhill section, determining, by a driving information detection device, whether a predetermined inertial driving condition is satisfied, before the vehicle enters the downhill section, and deciding, by a control device, a shifting mode of the vehicle depending on the downhill grade, and controlling a transmission according to the decided shifting mode, at a predetermined time before the vehicle enters the downhill section.

A vehicle includes an engine, a plurality of drive wheels, a vehicle transmission configured to transmit power from the engine to the plurality of drive wheels, one or more vehicle attitude sensors, and an electronic control unit communicatively coupled to the one or more vehicle attitude sensors and the vehicle transmission. The electronic control unit is configured to receive a signal from the one or more vehicle attitude sensors, determine a degree of vehicle descent based on the signal received from the one or more vehicle attitude sensors, and downshift the vehicle transmission based on the degree of vehicle descent determined based on the signal received from the one or more vehicle attitude sensors.
