摘要： A method and a device for controlling a motor vehicle drive train determine the direction of rotation of the drive train by evaluating sensor signals of a first sensor unit on the output side of the drive train. The first sensor unit includes a sensor wheel fastened to a rotatable component on the output side of the drive train and two rotational speed sensors which are fixed with respect to a housing and are placed circumferentially next to one another. In order to speed up the determination of the direction of rotation, the sensor signal of a second sensor unit on the input side of the drive train is evaluated. The second sensor unit includes a sensor wheel that is fastened to a rotatable component on the input side of the drive train and a rotational speed sensor that is fixed with respect to the housing.

摘要： A vehicle, such as a loader, has an operator-controlled hydrostatic drive that includes hydrostatic motors to drive wheels. The speed of the motors is proportional to an operator input provided to a controller that regulates the flow of hydraulic fluid from a pressure source to the motors. The regulation of fluid under pressure to the motors is achieved by utilizing electrical displacement control pumps that provide fluid flow in proportion to an input signal. The motors are fixed displacement motors, and when the wheels overrun as the vehicle rolls down an incline, the motors will act as pumps. The movement of the wheels is sensed to provide a signal to the controller to adjust one or both of the control pumps to provide a balancing counter pressure at the work port of the motor to insure that the vehicle will not creep or roll when it should be stopped.

摘要： In an infinite speed ratio transmission, a rotation of an input shaft (1) is input both to a continuously variable transmission (2) and a fixed speed ratio transmission (3). A CVT output shaft (4) of the toroidal continuously variable transmission (2) is joined to a sun gear (5A) of a planetary gear set (5), an output shaft (3C) of the fixed speed ratio transmission (3) is joined to a planet carrier (5B) of the planetary gear set (5), and a vehicle is driven under the output of a ring gear (5C) of the planetary gear set (5). A controller of the infinite speed ratio transmission comprises an actuator (30) which varies an amount of torque transmitted between the input shaft (1) and the CVT output shaft (4). A microprocessor (80) controls the actuator (30) so that a torque in the opposite direction to the vehicle travel direction shown by a selection range of a selector lever (86) is not transmitted by the continuously variable transmission (2).

摘要： Disclosed is a method for operating a multi-gear vehicle transmission having a plurality of shifting elements (A, B, C, D, E) for engaging gears of the vehicle transmission. In a neutral gear, in which some of the shifting elements (A, B) are already actuated, a transmission input (1) is decoupled from a transmission output (2) of the vehicle transmission. In a driving gear the transmission input (1) is coupled to the transmission output (2) of the vehicle transmission by closing the shifting elements (A, B, C, D, E) associated with the driving gear, in order to propel the vehicle. With the neutral gear engaged a transmission condition is determined, and if a transmission condition with elevated drag losses exists, then in addition to the shifting elements (A, B) actuated in the neutral gear a shifting element (D) associated with a reversing gear of the vehicle transmission is also closed.

摘要： A range determination device is applied to an automatic transmission provided with an input portion, an output portion, and a range switching mechanism which transmits rotation of the input portion to the output portion, and which is operative to switch the range of the automatic transmission between a forward range and a reverse range, in which directions of transmitting rotation from the input portion to the output portion are different from each other. The range determination device includes a rotational state detection unit which detects a rotational state of a predetermined rotary member included in the range switching mechanism, and a determination unit which determines that the forward range or the reverse range is attained on the basis of the rotational state of the rotary member detected by the rotational state detection unit.

摘要： A method of controlling an automatic geared transmission of a vehicle drive train. The transmission is linked, on the input side, to a hybrid drive which comprising an engine and an electric motor and, on the output side, to an axle drive and wheels. During vehicle stand still with the engine and/or electric motor operating and a disengaged drive train, rolling of the motor vehicle is prevented, or at least limited, by shifting the transmission. When the automatic geared transmission is in the neutral position (Gl=N), a safety function is activated to avoid uncontrolled rolling of the vehicle in which actuation of shift operating elements, the throttle and the brake pedal, as well as the rolling speed, are captured by sensors and in which, when the drive operating elements (shift operating element xSBE=0, throttle xFP=0, brake pedal xBP=0) are not activated, a starting gear is engaged once a predetermined limiting speed (vRoll>vGr) is exceeded.

摘要： The invention relates to a transmission synchronisation method and a transmission synchronisation device for at least two transmission units (T1, T2). The synchronisation takes place in that in each case an output revolution speed (n1, n2) of an axle drive shaft arranged in a transmission (T1, T2) is adjusted by means of a first and second adjustment unit (ADU1, ADU2). The synchronisation of the first and second transmissions (T1, T2) takes place by a result value (cal_out) of an arithmetic logic unit (140) being conducted to the second adjustment unit (ADU2) arranged at the second transmission (T2), dependent on the first transmission (T1) and on the reference value (v_set) of a preselection unit (100).
