Abstract:
A vehicle includes a power source, such as an engine, an electric machine, or combination thereof. A torque converter is selectively coupled to the power source such that drive torque can be altered before being distributed into a transmission of the vehicle. A torque converter bypass clutch enables torque from the power source to selectively transmit directly to the transmission with little or no torque altering provided by the torque converter. At least one controller in the vehicle is in communication with a storage device. The controller sends road condition data to the storage device regarding a road segment. During a subsequent drive to or over the road segment, the controller receives the road condition data and enables the torque converter bypass clutch to slip to dampen driveline disturbances when the vehicle passes over the road segment.
