AI Technical Summary

Problems solved by technology

Improperly timed transmission shifts may disrupt the vehicle, may adversely affect the intended path defined by driver input, exceed the tire's adhesion / traction limits to the track, and may adversely affect the overall speed at which the vehicle is able to traverse the route, thereby potentially increase lap time

Embodiment Construction

[0028] Referring now to the drawings, wherein said drawings are for illustration of certain exemplary embodiments only and not for the purpose of limiting them, figure 1 An exemplary vehicle propulsion system is schematically depicted showing the relationship between input torque applied through a transmission and output torque in accordance with the present disclosure. The vehicle 10 includes an engine 20 , a transmission 30 and a transmission control module 40 . Under normal operation (including vehicle acceleration, steady state operation, or gradual deceleration), the engine 20 supplies input torque to the transmission 30, and the transmission 30 supplies the input torque through the gear ratios inside the transmission and, in an automatic transmission, through the torque converter This is converted to output torque to power the driveline of the vehicle 10 . While the exemplary embodiment may include an automatic transmission, the present disclosure may be used without li...

Abstract

A vehicle propulsion system includes an engine for generating torque for propelling the vehicle, a transmission selectively coupled to the engine for receiving torque from the engine and having a plurality of gear selections each of which have a gear ratio which converts the torque from the engine to an output torque, a vehicle location identifier that identifies a location of the vehicle and provides a vehicle location signal indicating a location of the vehicle, and a controller that is programmed to record a shift history comprising gear selection, duration of gear selection, and vehicle location of each gear selection, identify a gear selection having a duration less than a predetermined duration, and revise a shift parameter for a gear selection having a duration less than the predetermined duration.

Description

technical field [0001] The present disclosure relates to a vehicle propulsion system and a method for controlling a vehicle propulsion system. Background technique [0002] This background generally presents the context of the disclosure. To the extent that the work of the named inventors is described in this background and aspects of this specification, it is not an admission that it was prior art at the time of the filing of this disclosure, nor is it expressly or impliedly admitted to be part of the present disclosure. current technology. [0003] Vehicle propulsion systems include a transmission that converts torque from one or more rotating shafts to torque on one or more rotating shafts. The transmission can utilize discrete gear states to achieve the various torque transfer and conversion functions required. A transmission shift includes disengagement of a first clutch, interrupting torque transmitted through the transmission, and engagement of a second clutch, re-...
