Method to control a road vehicle for the execution of a multiple downshift in a drivetrain provided with a servo-assisted transmission

A method to control a road vehicle for the execution of a multiple downshift in a drivetrain provided with a servo-assisted transmission; the control method comprises the steps of: detecting a condition of slowing down of the road vehicle and, simultaneously, detecting a driver's request for a multiple downshift; carrying out, in succession, a plurality of downshifts while the road vehicle is slowing down and in an autonomous manner regardless of further interventions of the driver; determining a duration of a shift time interval; and carrying out each downshift following a first downshift when said shift time interval has exactly elapsed since the previous downshift.

Driving force transmission device and control method for driving force transmission device

A driving force transmission device includes an input rotation member and output rotation member, a multiple-disc clutch, a pressing mechanism, and a control device that includes a current supply circuit. The control device is configured to compute a torque command value based on a state of a vehicle, the torque command value being a driving force that needs to be transmitted by the multiple-disc clutch, to compute a current command value, to correct the current command value, and to control the current supply circuit such that an electric current depending on the current command value is supplied to the pressing mechanism. The control device is configured to perform the correction so as to increase or decrease the current command value by a correction amount depending on a change rate of the torque command value.

METHOD FOR OPERATING A MOTOR VEHICLE COMPRISING A POWER TAKE-OFF UNIT
20220185286 · 2022-06-16 ·

The present invention relates to a method for operating a motor vehicle. A request for coupling a power take-off is detected. It is checked (12) whether relevant boundary conditions for coupling the power take-off are fulfilled. If the boundary conditions are fulfilled, a system pressure for actuating the power take-off clutch is built up (16). It is checked (18) whether sufficient system pressure to actuate the power take-off clutch has been built up. When sufficient system pressure has been built up, a confirmation signal is produced (20). In reaction to the confirmation signal, a driving transmission control unit is modified (34) in order to actuate the at least one shifting element of the driving transmission with a higher actuation pressure than with an unmodified driving transmission control unit.
