Abstract
Methods and systems are provided for a vehicle hill control. An example of a method may include during a vehicle stopped condition, operating with a clutch of a transmission engaged to mechanically lock the transmission, the transmission having a plurality of power inputs including receiving input from an electric machine and a prime mover; releasing at least one of the clutch or a service brake, and while releasing, concurrently adjusting an output magnitude of the electric machine responsive to speed control to control to a zero vehicle speed. In some examples, the method may further include learning a torque output of the electric machine required to maintain the zero vehicle speed upon fully releasing the clutch or service brake. In an example, the method may include estimating a road grade based on the learned torque output.
