Abstract
Methods and systems for controlling a maximum power output of an electric propulsion system are described. In one example, a state machine generated from executable instructions controls a maximum power output of an electric propulsion systems. The state machine permits additions states and changes to conditions that facilitate transitioning between the various states without having to completely reconstruct the maximum power output method.
Claims20
An electric propulsion system, comprising:
- an electric machine;
- an inverter electrically coupled to the electric machine;
- and
- one or more controllers including executable instructions that cause the one or more controllers to generate a state machine configured to control maximum power output of the electric propulsion system, where the state machine is in exactly one of a plurality of states at a time, and where the plurality of states include at least one state that permits output power of the electric propulsion system to exceed a rated output power of at least one component of the electric propulsion system and at least one state that permits output power of at least one component of the electric propulsion system to be constrained to less than the rated output power of the at least one component.
A method for operating a vehicle, comprising:
- moving between states of a state machine to control a maximum power output of an electric propulsion system, where the state machine includes a plurality of states and permits entry to exactly one state at a time.
A method for operating a vehicle, comprising:
- constraining a driver demand torque or power for a vehicle propulsion system in response to moving between states of a state machine to control a maximum torque or power output of an electric propulsion system, where the state machine includes a plurality of states and permits entry to exactly one state at a time, and were constraining the driver demand torque or power includes adjusting a maximum commanded driver demand torque or power.
