Abstract: A system according to the present disclosure includes a fuel control module and at least one of a desired air per cylinder (APC) module and a predicted manifold absolute pressure (MAP) module. The desired APC module determines a desired amount of airflow to each cylinder of an engine. The predicted MAP module predicts a pressure within an intake manifold of the engine at a future time. The fuel control module selectively adjusts a fuel injection parameter of the engine based on at least one of: a change in the desired air per cylinder from a first time to a second time; and a change in the predicted manifold pressure from the first time to the second time.

Abstract: A voltage measuring module measures first and second voltages at first and second electrical connectors of a fuel injector of an engine. A first summer module determines a first sum of (i) a difference between the first and second voltages and (ii) N previous values of the difference between the first and second voltages, wherein N is an integer greater than or equal to one. A second summer module determines a second sum of (i) the first sum and (ii) M previous values of the first sum, wherein M is an integer greater than or equal to one. A first difference module determines a first difference based on the second sum. A second difference module determines a second difference between (i) the first difference and (ii) a previous value of the first difference. An injector driver module selectively applies power to the fuel injector based on the second difference.

Abstract: A delay module, based on a base request received for a first loop, sets a delayed base request for a second loop. A first period between the first and second loops corresponds to: a first delay period of an oxygen sensor; and a second delay period for exhaust to flow from a cylinder of an engine to the oxygen sensor. A closed loop module determines a closed loop correction for the second loop based on: the delayed base request for the second loop; a measurement from the oxygen sensor; the closed loop correction for the first loop; and the closed loop correction for a third loop. A second period between the second and third loops corresponds to the first delay period of the oxygen sensor. A summer module sets a final request for the second loop based on the base request plus the closed loop correction for the second loop.

Abstract: A fuel control system according to the principles of the present disclosure includes a parameter determination module, a parameter learning module, and an injector driver module. The parameter determination module determines a parameter of a fuel injector in an engine at an operating condition of the engine. The parameter learning module identifies index values in a table based on the engine operating condition and adjusts learned values of the fuel injector parameter corresponding to the index values based on the determined value of the fuel injector parameter. The injector driver module selectively applies power to the fuel injector based on the learned values.

Abstract: Methods and apparatus are provided for controlling an autonomous vehicle. The control device includes an interface that establishes a connection to an autonomous vehicle, a processor that processes inputs and generates control commands to control at least one function of the autonomous vehicle, and an input arrangement with at least one control element that is assigned to a function of the autonomous vehicle. The control device transitions a controller of the autonomous vehicle to operate in at least one of a first remote operation mode and a second remote operation mode in which the autonomous vehicle is controlled by the control device, when the control device is connected to the autonomous vehicle via the interface. At least one function of a scope of functions of the autonomous vehicle is restricted in the first remote operation mode and the second remote operation mode.

Abstract: An internal combustion engine includes a method for operating including, determining, using an accelerator pedal position sensor, an operator request for power and determining an engine operating point based upon the operator request for power. A motored-cylinder temperature is determined based upon the engine operating point, and a knock-limited combustion phasing point is determined based upon the motored-cylinder temperature and the engine operating point. Engine operating parameters associated with achieving the knock-limited combustion phasing point are selected. Operation includes controlling, by a controller, engine control states in response to the engine operating parameters associated with achieving the knock-limited combustion phasing point and the operator request for power.

Abstract: An injector driver module applies power to a fuel injector of an engine for a fuel injection event. A voltage measuring module measures first and second voltages at first and second electrical connectors of the fuel injector. A parameter determination module determines a maximum value based on a first difference between the first and second voltages, determines a minimum value based on the first difference between the first and second voltages, and determines a second difference between the maximum and minimum values. A diagnostic module, based on the second difference between the maximum and minimum values, indicates whether the fuel injector injected fuel in response to the application of power.
