Abstract: A method for managing an engine for which segment tasks are initiated at a moment referred to as “segment”, in order to determine setpoint values which must be available before a predetermined angular time, having the following steps: a) executing a segment task; b) determining the difference between the angular starting time for application of the setpoints and the position corresponding to the availability of the setpoint values; c) comparing the difference determined in step b) with a lower difference value and a greater difference value; and d) modifying the segment if the difference determined in step b) is not between the lower and greater difference values, the position of the segment being advanced if the difference determined in b) is less than the lower difference value and the position of the segment being delayed if the difference determined in b) is greater than the greater difference value.

Abstract: A vehicle control system, a vehicle control method, and a storage medium are provided. A stopping process stops fuel supply to one or more stopping cylinders and supplies fuel to one or more remaining cylinders during a load operation of an engine. During execution of the stopping process, a compensating process compensates for a decrease in output of the one or more stopping cylinders due to the execution of the stopping process by increasing output generated by combustion in the one or more remaining cylinders. The system control circuit causes, when the engine rotation speed of the engine is the same, the output after being increased by the compensating process to decrease as a shaft torque of the crankshaft of the engine increases.

Abstract: A system and method for monitoring vehicle performance and updating engine control parameters, which provides a solution to the problem of tuning engine control parameters for a vehicle. The core components of the invention are an engine controller coupled to an interface device which communicates with a remote device. Generally speaking, the components are configured as follows: the engine controller receives signals from various sensors in a vehicle and the engine controller controls the engine based on engine control parameters and the signals from the sensors. The interface device monitors the engine control and sensor signals and transmits information to the remote device. The remote device receives the information and sends back updated engine control parameters. The interface device receives the updated engine control parameters and communicates with the engine controller to update the engine control parameters using the updated engine control parameters.
