| A method and apparatus of a work machine wherein an operator traverses the work machine within an operator selected speed range. The operator positions a speed-range control device to select the operator selected speed range, thus, sending a speed-range signal from the speed-range control device to an electronic control module indicative of the position of the speed-range control device. The speed-range signal is converted to a scaling factor to re-calibrate at least one drive map indicative of the scaling factor. The operator then may position a control device to traverse the work machine within the operator selected speed range. | ||||||

| A method for controlling of a drive train of a vehicle having a multi-group transmission, an output mechanism and a control apparatus for the regulation of the drive train. The multi-group transmission consists of an automatic transmission and a range group. To change the ratio of the range group the drive train is relieved of load; a shifting element of the range group is closed; a shifting element of the range group is synchronized and opened; and a ratio of the automatic transmission is so altered that a change of the ratio of the multi-group transmission is less than in a case of an individual alteration of the ratio of the range group. | ||||||

| A control for enhanced range shifting in a computer (48) assisted vehicular compound transmission having a main section (16A) shifted by a manually operated shift lever (31) and a range section (16B) shifted in response to operation of a range shift selector, such as sensing shift lever (31) passing through a predetermined actuation point (AR) in the shift pattern. During a compound up-shift, if the vehicle reaches a speed greater than a predetermined value during a coasting condition and the shift lever is in a low range neutral position, then the range section up-shift is automatically completed without undue wear or damage to the range section synchronized clutch (130). It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b). | ||||||

| A control method/system for controlling range section (14) shifting in a range-type transmission (10) having a “repeat-H” shift mechanism. Under certain conditions, a shift from the highest ratio position in low range (4/8) toward the lowest ratio position (1/5) will cause an automatic shift to the high range, even if the range selector (96) is in the low range selection position. | ||||||

| A system for automatically effecting a range shift between high and low ranges in a multi-speed transmission includes a control that monitors the output speed of both the engine and the transmission. The ratio of the two speeds is compared to available ratios in a look-up table such that the control is constantly determining the engaged gear. In one embodiment, a driver provides an intention of the next gear to be selected to the control. Should the intended gear shift require a range shift from the engaged gear, the control actuates the range shift once the transmission has been moved to neutral. In a second embodiment, no driver intention is provided to the controller. Instead, the control compares the engine output speed to threshold values. If the threshold values predict a gear shift that would require a range shift to be effected from the currently engaged gear, then the range shift will be effected once the transmission has been moved to neutral. | ||||||

| A control system for an automatic transmission including a main transmission unit for setting a reverse stage and a plurality of forward stages and an auxiliary transmission unit connected in series to the main transmission unit and capable to be changed between two higher and lower stages. The control system comprises: a solenoid valve for outputting a signal pressure when at least the reverse stage and a predetermined one of the forward stages are to be set; a change-over valve for changing the signal pressure selectively into a signal pressure for setting the auxiliary transmission unit to a high gear stage and a signal pressure for controlling an engine braking state; and an engine braking control valve for controlling an engine braking frictional element at the predetermined forward stage into a released state in response to the signal pressure coming from the change-over valve. The acting state of the solenoid valve when the reverse stage is to be set and the acting state of the solenoid valve when the predetermined forward stage for making the engine braking ineffective is to be set are identical to each other. | ||||||

In addition, it is possible to widen the shiftable region for the sub transmission. | ||||||

| A four wheel drive torque transfer mechanism with a hydraulic control system is switchable between two wheel drive and four wheel drive during running of a vehicle having an automatic transmission. A reducer permits direct coupling or reduced speed ratio drives. A parking gear associating with the transfer device requires only small modification to the conventional parking mechanism. The hydraulic control system automatically actuates the reducer to provide a reduced speed-high torque output when a governor output responsive to vehicle speed, falls below a predetermined level. | ||||||

| The invention relates to a method (1, 21) for controlling a two-stage reduction gearbox of a motor vehicle in an open-loop and/or closed-loop manner, wherein two gears can be selected, namely a high gear and a low gear, wherein a shifting element is operated by the driver in order to shift from the high gear to the low gear or to shift from the low gear to the high gear, wherein a slope of the driving surface is determined and wherein a vehicle speed is determined. The loading of drive-off elements is minimised and, in particular, unintentional rolling of the motor vehicle is avoided in that a manual shift occurs during a standstill of the motor vehicle if the shifting element is operated and the brake pressure is greater than a minimum brake pressure characteristic curve (6, 7, 8, 9, 10, 11), wherein the minimum brake pressure characteristic curve (6, 7, 8, 9, 10, 11) depends on the slope of the driving surface, and/or in that a manual shift occurs while the motor vehicle is being driven if the shifting element is operated and if the speed of the motor vehicle is greater than a slope-dependent minimum speed. | ||||||

| A method is disclosed, for controlling a drivetrain of a vehicle, in particular an off-road vehicle, with a drive unit, a multi-group transmission, an output and a control device. The multi-group transmission comprises at least an automatic gearbox and a range-transfer box arranged thereafter. On changing the ratio in the range-transfer box, a) the drivetrain is unloaded by changing the torque of the drive unit, b) a switching element to be disengaged in the range-transfer box is disengaged, c) a switching element to be engaged in the range-transfer box is synchronised and engaged and d) a ratio of the automatic gearbox is changed such that a change in the ratio of the multi-group transmission is less than a change in the ratio of the ratio-transfer box alone. A combination of a ratio in the automatic gearbox and a ratio in the range-transfer box is selected by a command operational strategy, to give the desired ratio for the multi-group transmission, whereby the input speed to the range-transfer box for the desired ratio of the multi-group transmission is kept to a minimum. | ||||||
