In a vehicle including a shift-by-wire (SBW) transmission which may be parked in the neutral gear position of the transmission, method for controlling parking thereof includes determining whether the vehicle is in a situation in which neutral parking is required according to sensor information, when the vehicle is stopped, outputting first information configured to get a confirmation on whether a driver intends to perform the neutral parking from the driver, when the controller concludes that the vehicle is in the situation in which the neutral parking is required and when a park (P) gear position is input or an ignition of the vehicle is turned off, and controlling the SBW transmission to shift to a neutral (N) gear position, when there is an agreement input as a response to the first information.

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 and apparatus for evaluating the driving of a vehicle performing a journey on a road network is disclosed. The method comprises determining a fuel usage rate and an engine speed of a vehicle, and determining when the vehicle is coasting based upon at least one of the fuel usage rate and the engine speed of the vehicle. An acceleration of the vehicle, when the vehicle is determined to be coasting, is compared with a predetermined reference acceleration, and an application of braking during the coasting is determined based on the result of the comparison. A method and apparatus is also disclosed for determining a score indicative of the relative amount of time for which the vehicle is coasting without braking during a journey.

The present disclosure relates to a driving speed control device for an agricultural work vehicle, and a driving speed control method for an agricultural work vehicle, the device comprising: a confirmation unit for confirming set transmission information about a driving device of an agricultural work vehicle, and confirming a transmission mode for controlling an engine and a transmission of the driving device; an acquisition unit, which confirms, from the set transmission information, set revolutions per minute (RPM) relating to RPM of the engine when the transmission mode is an RPM designation mode, so as to acquire transmission information on the basis of the set RPM; and a control unit for controlling the driving device by using the acquired transmission information according to the transmission mode.

An apparatus for controlling transmission of vehicle may include a determining device to determine whether to perform deceleration control, based on the vehicle and a target for the deceleration control in front of the vehicle, a calculating device to sub-divide a distance between a current position of the vehicle and the target for the deceleration control into sections, and calculate a target distance for each section of the plurality of sections and a target speed of the section, based on a current speed of the vehicle and the distance between the current position of the vehicle and the target for the deceleration control, a gearshifting stage deciding device to determine a gearshifting stage for each section of the plurality of sections, based on the calculated target speed and the calculated target distance for the section by configuring a deceleration profile for each gearshifting stage, and a control device to control the transmission for each section based on the gearshifting stage for the section.

A system, method, and computer readable storage device are provided for providing a dynamic tachometer. Based on various signal inputs from a plurality of data sources, a tachometer may be dynamically modified to include visual information and assistance to the driver in relation to the vehicle's engine speed (i.e., revolution speed of the vehicle's crankshaft). The tachometer may include one or a combination of: dynamic shift point indicators, a target engine speed range indicator, an overspeed indicator, and a power take-off mode indicator.

Methods and systems are provided for estimating a maximum available torque reserve prior to a gear upshift and then during the upshift, generating the torque reserve to fill a torque hole. In one example, a method may include estimating a maximum torque reserve based on each of a driver torque demand, an auxiliary system demand, and a maximum generable engine torque and then opportunistically generating the torque reserve.

A method and system of controlling a drive-neutral-drive (D-N-D) shift in a multi-speed transmission. The method includes receiving a drive to neutral (D-N) shift request followed by a neutral to drive (N-D) shift request; initiating a drive to neutral (D-N) shift and determining an attained gear; determining a scheduled gear; determining if the scheduled gear is equal to the attained gear; and determining whether an off-going clutch for the drive to neutral (D-N) shift is in a hold state. The method further includes (I) aborting the drive to neutral (D-N) shift when (i) the scheduled gear is not equal to the attained gear and (ii) the off-going clutch for the (D-N) shift is in the hold state, or (II) completing a shift to neutral (N) when the off-going clutch for (D-N) shift is not in the hold state followed by shifting back drive (D).
