A method of controlling a drive device of a construction machine with a split transmission, which is at least coupled, at an input side, to a drive force source and, on the output side, with a drive range change transmission so as to set at least two shiftable drive ranges. The method includes a detection step (S1) for detecting drive dynamic requests for operation of the construction machine and a determination step (S2) for determining whether a drive dynamic request with an increased drive dynamic is present. If a drive dynamic request with increased drive dynamics is determined, then a shifting step (S4) is executed for shifting the drive range change transmission from a second, of the at least two drive ranges, to a first of the at least two drive ranges, to achieve increased driving dynamics of the construction machine.

An ECU determines whether or not a road surface changes from a low road surface to a high road surface based on image data obtained by a camera sense. When the ECU determines that the accelerator pedal operation amount deceases greatly in a predetermined determination period from a time point at which a drive wheel slip state occurs in a case where the ECU determines that the road surface changes from the low road surface to the high road surface, it prohibits upshift operation of an automatic transmission over a predetermined period from that time point.

In a shift device, a link is rotated as a result of a knob being slidingly operated. Here, the knob is coincidingly disposed on an axial direction of rotation side of the link. For this reason, the dimension of the shift device in the radial direction of rotation of the link can be reduced, and so the shift device can be downsized.

Provided herein are a transmission apparatus and a transmission system. The transmission apparatus includes a gear shift lever configured to receive a user command for shifting gear stages, a detent groove configured to be in contact with the gear shift lever and generate detent when the gear stages are shifted by the gear shift lever, a driver configured to generate a driving force when the ignition is turned off in a state in which the gear shift lever is positioned at a non-parking gear stage, and a driving force transmitter configured to separate the detent groove from the gear shift lever by the driving force.

A vehicle safety system for a vehicle includes a transmission and a shifter control configured to shift the transmission from one gear state to another gear state. The vehicle safety system includes at least one sensor configured to detect objects around the vehicle. The vehicle safety system includes a control module configured to diagnose a presence of an object behind the vehicle based on a signal received from the at least one sensor and to prevent the shifter control from shifting into a reverse gear state based on the diagnosed presence.
