Abstract: Methods and systems for improving vacuum generation for an engine that may be operated at higher altitudes are presented. In one non-limiting example, a transmission that is mechanically coupled to the engine may be shifted from a gear to neutral in response to an actual total number of times a vehicle brake pedal is applied and partially released while the vehicle is stopped and the brake pedal is applied.

Abstract: The present invention relates to a control system for a vehicle powertrain (3). The vehicle powertrain (3) includes a transmission (27), a launch control clutch (31), and a transfer case (39) selectively operable in a high range and a low range. The control system includes a monitor (53, 55) for monitoring one or more operating parameters of the launch control clutch (31) and/or the transmission (27). The control system comprises a controller (49) configured, in dependence on said monitoring means determining that said one or more operating parameters are above a predefined operating threshold or outside a predefined operating range, to output a notification to the user to select said low range; and/or to output a transfer case control signal to the transfer case (39) automatically to select said low range.

Abstract: An electronic control unit senses an actual shift range of a automatic transmission by executing a range determination operation, which determines the actual shift range of the automatic transmission based on a rotational position of a manual shaft that is sensed with an encoder. The control unit prohibits the execution of the range determination operation throughout a range determination operation prohibiting period, which is a predetermined time period and starts from a time point of starting rotation of the rotor of the electric motor unit toward the target rotational position.

Abstract: The invention concerns a procedure and a control apparatus for the control of a drivetrain, which comprises at least one automatic clutch, at least one automatic shifting transmission, one control apparatus for the control of the at least one automatic clutch and of at least one automatic shifting transmission as well as at least two transmission idling positions in the drivetrain. In order to avoid dangerous situations, which could arise from an improper automatic input of a neutral position of a transmission and a thereto connected automatic closure of the clutch. The proposal is, that the control apparatus, by way of the shifting of an automatized shifting transmission into a neutral position, to at least two transmission idling positions, the neutral position is put into action.

Abstract: A controller-assisted, manually shifted transmission system having a control system and method for controlling automatic range shifts are disclosed. Automatic range shifts are determined by control logic utilizing predetermined logic rules to evaluate transmission system criteria. The control logic determines a set of potential target gear ratios. Engine overspeed tests evaluate the set of potential target gear ratios in combination with the transmission system criteria. The appropriate range shift is determined and executed based on the selected target gear ratio.

Abstract: 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.
