摘要： A control unit in a work vehicle executes an automatic downshift for shifting a transmission from a current speed range to a speed range that is lower than the current speed range when at least a first condition, a second condition, a third condition, and a fourth condition are satisfied. The first condition is that an operating amount of an accelerator operating member of the work vehicle is equal to or greater than a predetermined accelerator threshold. The second condition is that a vehicle speed of the work vehicle is less than a predetermined speed threshold. The third condition is that a vehicle acceleration of the work vehicle is equal to or less than a predetermined acceleration threshold. The fourth condition is that that the hydraulic pressure of a hydraulic fluid supplied to a brake device of the work vehicle is less than a predetermined brake threshold.

摘要： A vehicle includes an engine with an associated engine-speed sensor, and wheels each having a respective wheel-speed sensor. The vehicle also includes a continuously variable transmission (CVT) coupled to the engine and configured to operate at variable input-to-output ratios. At least one controller is programmed to reduce the operating ratio of the CVT in response to the engine-speed sensor indicating the engine is operating at idle speed and the wheel-speed sensor indicating the velocity is approximately zero. This provides less noise, vibration and harshness in the vehicle due to the reduced ratio that is possible during conditions in which a vehicle launch in that reduced ratio may not be acceptable.

摘要： A control apparatus for an automatic transmission is provided with an automatic gearshift mode and a manual gearshift mode. The control apparatus changes a gearshift characteristic of the automatic transmission in response to a situation where an accelerator pedal opening is smaller than a predetermined opening, so that downshifting occurs at higher vehicle speed than in a situation where the accelerator pedal opening is greater than or equal to the predetermined opening. While the manual gearshift mode is being selected, the control apparatus inhibits change of the gearshift characteristic until downshifting is performed once, and permits change of the gearshift characteristic after downshifting is performed once.

摘要： A shift mistake detection apparatus detects an operation value of an accelerator pedal in a vehicle and a shift range selected by a shift operation of a driver of the vehicle (e.g. reverse, drive, park). The apparatus detects a shift mistake operation when (i) the shift range selected by the shift operation is in a reverse range and the vehicle begins to travel in reverse according to an operation of the accelerator pedal, and (ii) a steep step operation and a steep return operation of the accelerator pedal is detected. The steep step and return operations of the accelerator pedal have an operation value that is greater than or equal to a normal operation value, where the normal operation value may be a value detected when a driver of a vehicle intentionally travels in reverse (i.e., there is no shift mistake).
