Abstract

The present disclosure provides a hybrid vehicle. A method for controlling a hybrid vehicle having an engine includes automatically stopping the engine while towing in response to a vehicle power demand falling below a current available electrical power, and when the vehicle power demand falls below the current available electrical power for a first excursion to start the engine automatically. A hybrid vehicle comprising: an engine; an electric machine; a trailer hitch; a controller configured to command the engine to start at a torque offset below an engine torque-on schedule for an untowed vehicle in response to the vehicle being towed, wherein the Torque offset is based on vehicle load. A method for controlling a hybrid vehicle having a trailer hitch includes: detecting that the trailer hitch is in use; commanding an engine stop; to command the engine to start.

Description

technical field [0001] Embodiments relate to a hybrid vehicle and control of the vehicle while the vehicle is being towed. Background technique [0002] A hybrid vehicle may have a first prime mover and a second prime mover, such as an internal combustion engine and an electric machine. The vehicle can be operated using either prime mover or both. The vehicle can be electrically operated depending on the vehicle load (including driver demand and other vehicle accessory loads) and the amount of available electrical power. When the battery's state of charge reaches a lower limit, the engine may be started to provide additional power to the vehicle. The engine can also be started when the power or torque demand of the vehicle would exceed the power or torque available from the electric machine. [0003] Hybrid vehicles may be equipped with a towing package. The tow kit includes the trailer hitch and the trailer light electrical connector. When a load (eg, a trailer) is con...
