摘要:
Optimum control is performed in one cylinder of an internal combustion engine. By determining a desirable control operation stage for each cylinder in advance on the basis of engine parameters. Control operation is executed at the timing where the operation stage for each cylinder reaches the determined control operation stage.

The method for controlling operation of a vehicle having at least two possible operating modes includes calculating and/or determining the operating variables and/or control variables of at least one active one of at least two possible operating modes in a first continually repeated predetermined time interval and calculating and/or determining the operating variables and/or control variables of at least one inactive one of the at least two possible operating modes in at least one other continually repeated predetermined time interval. The first predetermined time interval is shorter than any of the one or more other predetermined time interval(s). A device for performing the method is also described.

An engine includes an electronic controller which samples the pressure in the induction system once per rotation of the crankshaft. The controller is configured to determine the minimum voltage signal output by the pressure sensor. The controller then uses the minimum pressure sensed by the pressure sensor to control the fuel injection of the engine. The controller may include two and/or three dimensional maps for predicting the appropriate timing for sampling the pressure sensor. The engine also includes a smoothing system so as to provide for more accurate sampling of the pressure within the induction system.

The present invention provides a system and method to adjust temporarily the quantity of fuel delivered to the cylinders of a fuel injected engine. The present invention allows a service technician to temporarily adjust the quantity of fuel being delivered to each cylinder or all cylinders of an internal combustion engine. The system includes an internal combustion engine having therein an electronic control unit capable of controlling the fuel quantity delivered to each cylinder and a general service computer connectable thereto and capable of transmitting data to the ECU. When instructed by the service technician, the service computer sends signals to the ECU to adjust fuel injector data to the fuel injectors of so as to increase or decrease the amount of fuel being delivered to the fuel injected engine.
摘要:
In an output controlling method for controlling output of a driving power source or motor installed in a vehicle, the relationship between a primary output-controller, which is manipulated by the user, and a secondary output-controller, which directly operates the motor, is regulated by control parameter subjected to evolution by using evolutionary computing based on at least one of the following: the user's characteristics, driving conditions, environmental changes, and deterioration of the drive power source with time. The evolution is conducted on-line or on a real-time basis. The primary output-controller includes an acceleration pedal or grip, and the secondary output-controller includes a throttle valve for an internal combustion engine or a running current controller for an electric motor.

A system and method for use in a motor vehicles is disclosed for calculating a fuel multiplier during transient engine operation. The fuel multiplier modifies the amount of fuel released from a fuel actuator into an engine. The fuel control system uses neural network logic to establish the fuel multiplier. The neural network logic involves taking inputs from engine sensors, processing the inputs through an input layer, a hidden layer and an output layer resulting in a fuel multiplier.

A method and a device for controlling the drive unit of a vehicle are provided, in which, in addition to the selection variable for an output variable of the drive unit, another setpoint variable representing the required dynamic setting of the output variable is preselected. The manipulated variable of the drive unit to be influenced is selected on the basis of the selection variable and the additional setpoint variable.

A fuel control system for an internal combustion engine includes a processor for determination of the timing and length of control pulse signals to an injector driver for turning an injector on and off. The method and an apparatus for delivering fuel to the injectors is according to a schedule that is adjusted throughout a variety of operating conditions with a minimum of chronometric or throughput loading by scheduling a circular queue of a plurality of buckets determined as a predetermined portion of a combustion cycle. Each bucket is defined by an interval initiated by an event triggered interrupt. At the interrupt, the processor dequeues a list of pointers to fueling information data storage for each cylinder previously assigned to the bucket. The method then assigns each cylinder to at least one selected bucket according to predetermined logic determination and an injector demand signal.
