Abstract
Methods and systems are provided for adjusting driver demand wheel torque of a vehicle. The driver demand wheel torque may be adjusted as a function of a minimum wheel torque. The minimum wheel torque may be determined according to a plurality of torques that may be evaluated in three different phases.
Claims7
A system for operating a powertrain, comprising:
- one or more propulsion sources;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust a torque of the propulsion source in response to a minimum wheel torque request, where the minimum wheel torque request is a greater of a vehicle coasting drivability wheel torque, a powertrain capability minimum wheel torque, a smooth transition wheel torque, and a creep wheel torque.
Dependencies are inferred from the claim text.
