Abstract
Methods and systems for generating control instructions for a plurality of transmissions having dissimilar gear configurations via a common software framework are described. In one example, the common software framework provides a graphic interface whereby a user/implementer describes configurations of different transmissions. The software framework generates instructions for different transmission controllers that shift the transmissions.
Claims12
A method for shifting a transmission of a vehicle, comprising:
- defining one or more transmission torque path hardware configurations and an actuator configuration via one or more tables, the one or more tables including a first table populated according to the one or more torque path hardware configurations, where the first table receives a first input value to define a first transmission gear that transmits torque through a first transmission input shaft and a second input value to define that the first transmission gear does not transmit torque through a second transmission input shaft, where the first table receives the first input value to define a second transmission gear that transmits torque through a second transmission input shaft and the second input value to define that the second transmission gear does not transmit torque through the first transmission input shaft, the first transmission input shaft different from the second transmission input shaft and the first transmission gear different than the second transmission gear, the one or more tables configured to accept input for a plurality of different transmission hardware configurations, and receiving data input to the one or more tables via a human/machine interface, where the numeric values include a particular numeric value that indicates it is optional to engage one of the two or more gear ratios;
- and
- shifting the transmission according to output of the one or more tables.
A system for generating executable instructions for shifting a transmission, comprising:
- a computer readable medium including executable instructions to generate a group of tables and shift the transmission according to output of the group of tables, the group of tables describing one or more transmission torque path hardware configurations, a plurality of coupling configurations, and an actuator configuration, where the group of tables includes a first table that is configured to receive input to define three gear ratios of the transmission that are selectively engaged to engage a sole forward gear of the transmission, where the input includes three numeric values that define an order of engagement of the three gear ratios to engage the sole forward gear such that gear ratios associated with lower numeric values are engaged before gear ratios associated with higher numeric values are engaged, and a first of the plurality of coupling configurations configured to couple a first transmission input shaft to a second transmission input shaft at a first location and a second location, the first location between a first input clutch and a second coupling configuration, the second location between a second input clutch and a third coupling configuration.
