Methods and systems are provided for using remote sensor data for a vehicle. The vehicle includes a control system, an interface, and a processor. The interface is configured to automatically obtain one or more remote sensor values via a wireless network from a remote source that is remote from the vehicle. The processor is coupled to the control system and the interface, and is configured to control one or more functions of the control system using the one or more remote sensor values.

The present disclosure generally relates to a computer implemented method for controlling an exhaust gas aftertreatment system (EATS), specifically applying a scheme for preventing heat reduction at the EATS based on the estimated heat reduction. The present disclosure also relates to a corresponding exhaust gas aftertreatment system (EATS) and a computer program product.

The electric energy provided to some loads in a vehicle is limited or controlled by a power controller that receives a signal specifying how much power should be provided to the load. When the link providing the power-specifying signal is lost, the controller adjusts the power to the load according to an internal temperature of the controller instead of simply providing full power to the load.

A control system for an engine includes one or more processors configured to determine when a change in one or more of oxygen or fuel supplied to an engine. The one or more processors also are configured to, responsive to determining the change in oxygen and/or fuel supplied to an engine, direct one or more fuel injectors of the engine to begin injecting fuel into one or more cylinders of the engine during both a first fuel injection and a second fuel injection during each cycle of a multi-stroke engine cycle of the one or more cylinders.

An engine start control device is provided with: a starter relay that is provided between a battery and a starter motor; a start abnormality determining means that determines the occurrence of start abnormality of an engine; and a start control means, which turns on the starter relay, and starts supplying power from the battery to the starter motor in the cases where a start instruction signal is inputted from a start switch, and which turns off the starter relay in the cases where the start abnormality determining means determined the occurrence of start abnormality of the engine.

A computer control network is connected to a multiple-cylinder engine and implements aftertreatment temperature management. Processors are configured to determine an aftertreatment temperature-efficient air to fuel ratio that satisfies the sensed power output request, determine an air to fuel ratio adjustment, select an in-cylinder exhaust gas recirculation technique, select at least one EGR cylinder of the multiple-cylinder engine to implement the in-cylinder exhaust gas recirculation technique, and control the intake valves to open and the exhaust valves to close for the selected at least one EGR cylinder to adjust the oxygen and particulate content of the exhaust gas by applying at least a second compression stroke of the respective reciprocating piston of the at least one EGR cylinder to the exhaust gas to push the exhaust gas through to the intake manifold.

The inhibition device includes a micro-controller configured with a triggering condition including a number of intervals and, for each interval, a corresponding duration and a corresponding threshold. Each interval is a range specifying how much the vehicle's acceleration pedal has changed its position in terms of percentages of a pedal stroke. Each duration specifies the fastest time duration allowable for the acceleration pedal to attain a corresponding interval of pedal position change. The micro-controller converts progress signals of the acceleration pedal to corresponding percentages, obtains a difference DEF between the successive percentages, records a time duration RES between successive progress signals, and calculates DEF/RES=X. When X is greater than or equal to a threshold of a corresponding interval, the micro-controller sends an idle signal to the vehicle's engine control unit or intercepts the progress signals to prevent them from reaching the engine control unit.

The present invention provides a novel combination of devices to measure and transmit to an electronic controller data pertaining to differential pressures, temperatures, regeneration status, exhaust content, accumulated gas consumption and substitute fuel consumption. The electronic controller compares the data to thresholds; when the controller receives signals indicating these thresholds or limits are met, the controller causes the gas substitution rate to be diminished or set to zero until after-treatments elements are fully regenerated thereby facilitating integration of a mixed fuel system with an application internal combustion engine.

An injection control device includes a control IC that obtains, as sample data, a time change of a voltage generated when a fuel injection valve is driven, and determines a valve closing timing at which injection of fuel from the fuel injection valve is stopped by calculating a degree of variation from the sample data of the voltage. Further, the control IC changes the calculation of the degree of variation when a predetermined condition is satisfied.
