A method for controlling a vehicle transmission system having a clutch system includes generating a torque-pressure (T-P) gain deviation based on a T-F characteristic and a nominal T-F characteristic for the clutch system, generating a pressure magnitude deviation based on the set of pressure values and the set of nominal pressure values, determining whether a T-F characteristic deviates from the nominal T-F characteristic based on the T-P gain deviation and the pressure magnitude deviation, identifying the T-F characteristic as deviating in response to the T-F characteristic departing from the nominal transfer characteristic, and issuing a notification regarding the deviating T-F characteristic to perform a corrective action related to the clutch system.

Method and system for a vehicle clutch performance detection system using clutch torque and clutch pressure

A vehicle includes a powertrain, an inertial measurement unit configured to measure inertial forces exerted onto the vehicle, and a controller. The controller is programmed to control the torque at the powertrain based on a mapped relationship between the inertial forces and a vehicle velocity, wherein the mapped relationship utilizes at least one mapping parameter. The controller is further programmed to estimate a mass of the vehicle based on the mapping parameter.
