Abstract:
1. A method of controlling a vehicle including a transmission having at least one clutch, the method comprising: detecting vibration in a drivetrain of the vehicle with a fore/aft accelerometer; identifying an operating regime of the vehicle concurrently with the detected vibration when the detected vibration is outside a predefined allowable range; wherein identifying the operating regime of the vehicle includes identifying a value for a plurality of parameters, including at least one of an engine speed, a transmission input shaft speed, a transmission output shaft speed, a speed gradient, an engine torque, a throttle position, a clutch input torque, or a temperature of a component; adjusting a control strategy used to control the drivetrain during the identified operating regime, to define a revised control strategy that avoids the identified operating regime; wherein adjusting the control strategy includes adjusting the identified value of one of the plurality of parameters; and applying the revised control strategy to control the drivetrain to mitigate vibration in the drivetrain.
