Abstract: A method in a control arrangement of a vehicle and a control arrangement for a vehicle for downshifting gears in an uphill slope are presented. The method comprises, when the vehicle is travelling in an uphill slope using an initial gear of the vehicle's automated manual transmission gearbox: simulating at least one speed profile for a downshift to, and a usage of, at least one gear; determining that a minimal speed of each one of the at least one simulated speed profile has a value indicating that the actual speed of the vehicle will be less than or equal to zero in the uphill slope; opening a clutch before is reduced to a value less than zero; activating at least one vehicle brake; shifting vehicle's automated manual transmission gearbox to a start gear; closing the clutch; and deactivating the at least one vehicle brake.

Abstract: A method of controlling driving of a CVT vehicle during cornering performed by a controller, may include determining whether it is necessary to perform an auxiliary control process to enhance a re-acceleration response after entering the corner, by determining a travelling state of the vehicle; setting a target gear ratio instead of a gear ratio obtained based on a shift pattern when the determining produces an affirmative result indicating that it is necessary to perform the auxiliary control process; and performing gear shifting of a CVT to follow the target gear ratio set in the setting of the gear ratio.

Abstract: Methods and devices for determining speed control management settings are provided. A vehicle configuration is obtained, specifying at least a transmission, including a number of gears present in the transmission. One or more speed control management modules, such as progressive shift and/or gear down protection modules, are selected by a customer. One or more default progressive shift limits and a default gear down protection limit are calculated, along with gears for which they are active. Performance of the vehicle using the default speed control management settings is simulated and compared to typical vehicle performance. The customer may alter the speed control management settings within dynamically determined valid ranges. The speed control management settings are used in the manufacture or other configuration of the vehicle for the customer.

Abstract: A shift control device for an electrically driven vehicle, which is installed in the electrically driven vehicle including a motor as a drive source and an automatic transmission coupled to an output shaft of the motor, has a shift controller that performs shifting of the automatic transmission using a previously set shift line. The shift controller has, as the shift line, an electricity consumption prioritized shift line with priority placed to improve electricity consumption rate, and a driving force prioritized shift line with priority placed to suppress the frequency of shifting. The driving force prioritized shift line is used for a predetermined time after completion of the shift control using the electricity consumption prioritized shift line.

Abstract: A vehicle is provided. The vehicle includes an engine, a motor, and a controller. The controller is programmed to inhibit a scheduled transmission downshift and increase a torque of the motor for a specified period of time in response to a torque demand being greater than a maximum torque capability of the engine but less than a maximum combined torque capability of the engine and motor. Upon expiration of the specified period of time, the controller may permit the downshift to occur. The specified period of time may be based on a state of charge of a battery at a time when the torque demand exceeds the maximum torque capability of the engine.

Abstract: A computer-implemented shifting method for a vehicle is described. The method is based upon, at least in part, identifying a reference output torque at an output shaft associated with a transmission of the vehicle. The method includes reducing a torque capacity of an off-going output clutch from a starting capacity and determining a torque load for the off-going output clutch. The method includes maintaining a first transition torque capacity during a first transition period after the determining of the torque load, and increasing a torque capacity of the on-coming output clutch to a second transition torque capacity. The method includes maintaining the second transition torque during a second transition period. The method includes reducing the torque capacity of the off-going output clutch to a first final torque capacity and increasing the torque capacity of the on-coming output clutch to a final torque capacity.
