ELECTRIC-DRIVE VEHICLES, POWERTRAINS, AND LOGIC FOR COMPREHENSIVE VEHICLE CONTROL DURING TOWING

Presented are intelligent vehicles and control logic for provisioning comprehensive tow features, methods for manufacturing/operating such vehicles, and electric-drive vehicles with tow features for protecting the vehicle's powertrain and electrical components during towing. A method for controlling operation of an electric-drive vehicle includes a vehicle controller verifying initiation of a towing operation for the vehicle, and responsively determining if there is a drive system failure preventing the vehicle's traction motor from electrically connecting with its traction battery pack. If there is no drive system failure, the controller determines if the speed of the traction motor during towing exceeds a calibrated base speed; if so, the controller commands a power inverter to electrically connect the traction motor to the traction battery pack. If, however, the towed motor speed does not exceed the calibrated base speed, the controller responsively commands the power inverter to disconnect the traction motor from the battery pack.
