A system for pilot-controlled position guidance configured for use in a vertical take-off and landing (VTOL) aircraft, the system including a VTOL aircraft. The system including a graphical user interface (GUI) coupled to the VTOL aircraft, where the GUI is configured to receive an objective from a user as a function of the user's interaction with the GUI, transmit the objective to a controller, receive a control input from the controller, and display the control input to the user. The system also including a controller where the controller is configured to receive the objective for the GUI, calculate a control input as a function of the objective, and transmit the control input to the GUI.

Pilot-controlled position guidance for VTOL aircraft

A system for fault detection and control in an electric aircraft including an inertial measurement unit, the inertial measurement unit including at least a sensor configured to detect a torque datum associated with at least a propulsor. The system includes an observer, the observer configured to generate a torque prediction datum associated with the at least a propulsor, compare the torque prediction datum with the torque datum, and generate a residual datum as a function of the comparison. The system includes a mixer, the mixer comprising circuitry configured to generate, as a function of the residual datum, a torque priority command datum and transmit, to the at least a propulsor, the torque priority command datum.

Systems and methods for fault detection and control in an electric aircraft

Methods are provided for identifying degradation in components of a compressor recirculation valve (CRV). One method may include inferring degradation of the CRV based on adaptation of a compressor surge line outside an expected range.

Methods and systems for detecting compressor recirculation valve faults

Methods and systems are provided for controlling a boosted engine system, having a turbocharger and a charge air cooler, to limit overheating of a compressor outlet. In one example, a method includes predicting an engine torque profile based on current and future engine operating conditions. The method then models a compressor outlet temperature profile and reduces engine torque output to limit overheating of the compressor outlet.

Method and system for compressor outlet temperature regulation

Methods and systems are provided for controlling boost pressure in a staged engine system comprising a turbocharger and an upstream electric supercharger. In one example, a method may include coordinating the operation of the electric supercharger and an electric supercharger bypass valve and to open the electric supercharger bypass valve to reduce the extent and duration of electric supercharger overboost.

Method and system for boost pressure control

Methods and systems are provided for controlling boost pressure in a staged engine system comprising a turbocharger and an upstream electric supercharger. In one example, a method may include accelerating an electric supercharger to choke the flow of air to the engine in the event of turbocharger overboost.

A vehicle includes an engine and at least one controller. In response to a change in a rate of change of a driver control input to the vehicle, the at least one controller is programmed to alter conditions under which the engine will be started and stopped such that engine-on time increases due to the rate increasing and decreases due to the rate decreasing.

Adapting engine-on time to driver aggressiveness in a hybrid vehicle

Methods and systems are provided for controlling a wastegate coupled to a turbine. In one example, a method may include during steady engine operation, actuating a wastegate to introduce an oscillation in boost pressure, and updating gain of a wastegate feedback controller responsive to the oscillation in boost pressure.

System for wastegate control

Methods are provided for identifying degradation in components of a compressor recirculation valve (CRV). One method includes differentiating between degradation of a throttle of the CRV and a position sensor of the CRV based on each of a throttle inlet pressure and commanded position of the throttle of the CRV. The method also includes utilizing output from the position sensor of the CRV in response to the commanded position of the throttle of the CRV.

Diagnostic method for a compressor recirculation valve

Methods and systems for operating an engine that includes an electrically operated throttle are disclosed. In one example, mitigating actions are taken in response to degradation of the electrically operated throttle so that the engine may be operated in a way that allows a driver to reach a service area.

Method and system to mitigate throttle degradation

Methods and systems are provided for determining a cylinder air charge based on a boost manifold volume of an engine. In one example, a method may include inducing a compressor surge event, and updating the boost manifold volume in response to a difference between an actual surge pressure and an expected surge pressure. The method further includes determining the cylinder air charge based on the updated boost manifold volume.

Manifold volume determination based on surge frequency

Methods and systems are provided for diagnosing compressor bypass valve degradation. In one example, a method may include indicating degradation of a compressor bypass valve coupled in a compressor bypass based on intake aircharge temperature measured upstream of a compressor inlet via an air charge temperature sensor.
