A simulated shift system for a battery electric vehicle (BEV) includes a set of sensors configured to monitor a set of parameters indicative of driver input by a driver of the BEV and a controller configured to control an electric drive module (EDM) of the BEV, the EDM comprising a gear system connected to an electric motor and being configured to output drive torque to a driveline of the BEV, receive the monitored set of parameters, and, based on the monitored set of parameters, selectively control the EDM to adjust drive torque output therefrom to simulate transmission shift operations of a predetermined conventional automotive automatic transmission having four or more speeds.

Simulated shifts and modes for battery electric vehicle driving

Control systems and methods for a vehicle automatic transmission utilize a driver interface configured to receive input from a driver of the vehicle relating to a custom shift mode of the automatic transmission and a controller configured to monitor a driving history of the vehicle and, based on the driving history, determine a reduced shift sequence for the transmission to utilize during the custom shift mode, the reduced shift sequence specifying a subset of available forward gears of the transmission to utilize during the custom shift mode, the subset of gears being less than a total number of available forward gears of the transmission, such that one or more available forward gears are skipped in the reduced shift sequence, initiate the custom shift mode for the transmission, and during the custom shift mode, control shifting of the transmission according to the reduced shift sequence.

Systems and methods for programming a gear shift sequence for a custom shift mode of an automatic transmission

A transmission includes input and output shafts, a hybrid module coupled to the input shaft and a gearbox coupled to the module and output shaft. The hybrid module includes a first electric motor under driven by a gearset; a second electric motor coupled to a module output, a disconnect clutch coupled to the gearset and selectively to the input shaft; and a launch clutch coupled to the disconnect clutch and selectively to the module output. The gearbox includes three gearsets and five torque transmitting devices operable to generate six forward speeds. One torque transmitting device is a clutch brake applied with a piston that reaches over a park gear, and one is a selectable one way clutch. Two of the torque transmitting devices are radially stacked rotating clutches. The transmission includes and/or facilitates an engine only mode, an electric only mode, a hybrid mode and a battery charging mode.

Hybrid transmission for a motor vehicle

An automatic transmission system includes a housing containing automatic transmission fluid (ATF), a plurality of clutches configured to be engaged to generate gear ratios corresponding to forward speeds of the automatic transmission, wherein one clutch of the plurality of clutches is a friction clutch movable between a disengaged state, an engaged state utilized to create one or more gear ratios of the automatic transmission, and a slippingly engaged state between the disengaged state and the engaged state where the friction clutch is not engaged to create a gear ratio of the automatic transmission, and a controller configured to selectively move the friction clutch to the slippingly engaged state when the friction clutch is not being utilized to generate the one or more gear ratios, such that the friction clutch generates heat from friction to thereby rapidly heat the ATF in the housing and improve operating efficiency of the transmission.
