Systems, methods and apparatus for controlling operation of dual fuel engines are disclosed that regulate the fuelling amounts provided by a first fuel and a second fuel during operation of the engine. The first fuel can be a liquid fuel and the second fuel can be a gaseous fuel. The fuelling amounts are controlled to improve operational outcomes of the duel fuel engine.

Systems, methods, and apparatus for operation of dual fuel engines

A system includes a sensor array and a processing circuit. The processing circuit is operable to: store a policy; receive the sensor information from the sensor array; receive horizon information from a horizon system; input the sensor information and the horizon information into the policy; determine an output of the policy based on the input of the sensor information and the horizon information; control operation of a vehicle system according to the output; compare the sensor information received after controlling operation of the vehicle system according to the output relative to a reward or penalty condition; provide one of a reward signal or a penalty signal in response to the comparison; update the policy based on receipt of the reward signal or the penalty signal; and control the vehicle system using the updated policy to improve operation in view of the operating parameter.

Reinforcement learning control of vehicle systems

A method includes receiving, by a remote server, operating parameters regarding one or more components of a vehicle from a vehicle controller of the vehicle; retrieving, by the remote server, at least one of static information or dynamic information regarding one or more parameters ahead of the vehicle; determining, by the remote server, an adjustment for at least one of the one or more components of the vehicle based on (i) the operating parameters and (ii) the at least one of the static information or the dynamic information; and providing, by the remote server, an instruction to the vehicle controller regarding the adjustment.

Telemetry predictive control for vehicle operations

Systems, methods and apparatus for controlling operation of dual fuel engines are disclosed that regulate the fueling amounts provided by a first fuel and a second fuel during operation of the engine. The first fuel can be a liquid fuel and the second fuel can be a gaseous fuel. The fueling amounts are controlled to improve operational outcomes of the duel fuel engine.

A system for control of an internal combustion system having subsystems, each with different response times. Subsystems may include a fuel system, an air handling system, and an aftertreatment system, each being operated in response to a set of reference values generated by a respective target determiner. Calibration of each subsystem may be performed independently. The fuel system is controlled at a first time constant. The air handling system is controlled on the order of a second time constant slower than the first time constant. The aftertreatment system is controlled on the order of a third time constant slower than the second time constant. A subsystem manager is optionally in operative communication with each target determiner to coordinate control. Generally, dynamic parameters from slower subsystems are treated as static parameters when determining reference values for controlling a faster subsystem.

Hierarchical engine control systems and methods

Methods and apparatuses for calibration and control of various engine subsystems using a target value approach. Under the target value approach, the control of each engine subsystem is separated or decoupled to include a set of target values, or a reference value set. A subsystem has a corresponding target determiner, which provides a target value set, or reference value set, in response to a basis variable set and optionally an overall subsystem target. The basis variable set includes parameters selected to robustly characterize the variables that affect the operation of the particular subsystem. The target determiner is optionally calibrated to provide a reference value set within specifications of the subsystem. A physical subsystem controller operates in response to the reference value set.

Reference value engine control systems and methods

Methods, systems and apparatuses for inter-vehicle communication, fusion of sensor information, and information sharing resulting from inter-vehicle communication are disclosed along with control of one or more vehicles in response to information from one or more other vehicles.

Sensor fusion and information sharing using inter-vehicle communication

A method includes determining whether a urea refill event is detected, and clearing a quality accumulator value and clearing a latching abort command. The method includes determining whether urea fluid quality check abort conditions are met, and clearing the urea quality accumulator, latching the abort command, and exiting the reductant fluid quality check. In response to the abort conditions not being met, incrementing the urea quality accumulator according to an amount of urea being injected, and comparing the accumulated urea quantity to a low test threshold. The method includes, in response to the accumulated urea quantity being greater than the low test threshold, comparing the accumulated urea quantity to a high test threshold, and in response to the urea quantity being greater than the high test threshold, determining whether the a NOexceedance is observed and clearing a urea quality error in response to the NOexceedance not being observed.

System, method, and apparatus for aftertreatment system monitoring

Systems and apparatuses include a controller structured to: receive information indicative of an operating condition of a vehicle subsystem, receive information indicative of an external static condition, and receive information indicative of an external dynamic condition. The system is further configured to predict a fuel cut event based on at least one of the operating condition of the vehicle subsystem, the external static condition, and the external dynamic condition. Responsive to predicting a fuel cut event, the controller is structured to modulate at least one of a torque or a speed of the engine based on the operating condition of the vehicle subsystem and at least one of the information indicative of the external static condition and the external dynamic condition.

System and method for predictive engine and aftertreatment system control

An apparatus includes a sensor module, an offset diagnostic module, and a notification module. The sensor module is in operative communication with a cylinder pressure sensor and structured to acquire cylinder pressure data from the cylinder pressure sensor indicative of an actual in-cylinder pressure of a cylinder of an engine. The offset diagnostic module is structured to interpret the cylinder pressure data to determine an offset of the cylinder pressure sensor based on a reference in-cylinder pressure and the actual in-cylinder pressure. The notification module is structured to provide an offset error notification responsive to the offset being greater than a threshold offset.
