A smart governor system that intercepts and adjusts throttle commands when certain criteria are met based on vehicle operations and a user-selected transmission mode. The governor, when engaged, reduces a throttle command in order limit engine and/or ground speed.

A turbocharger control system of a vehicle includes a trigger module that generates a trigger signal when a transmission of the vehicle is in one of (i) park and (ii) neutral. A wastegate target module, in response to the generation of the trigger signal, sets a target opening of a turbocharger wastegate to a predetermined opening and independently of a position of an accelerator pedal. The predetermined opening is greater than zero percent opening of the turbocharger wastegate. A wastegate actuator module actuates the turbocharger wastegate based on the target opening of the turbocharger wastegate.

The turbocharged engine control device comprises a basic target torque-deciding part for deciding a basic target torque based on a driving state of a vehicle including an accelerator pedal operation state; a torque reduction amount-deciding part for deciding a torque reduction amount based on a driving state of the vehicle other than the accelerator pedal operation state; a final target torque-deciding part for deciding a final target torque based on the decided basic target torque and the decided torque reduction amount; and an engine output control part for controlling an intake air amount so as to realize a target air amount required for an engine to output the decided final target torque, wherein the engine output control part is operable, when an operating state of the engine falls within a supercharging region, to restrict a reduction in the intake air amount corresponding to a change in the torque reduction amount.

The engine controller includes an acceleration input detector that detects an accelerator pedal motion, a fuel injection amount calculator that calculates a target fuel injection amount, a fuel injection controller that controls the fuel injector, an EGR valve opening calculator that calculates a target EGR valve opening, and an EGR controller that controls the EGR valve. The EGR controller controls, after the accelerator pedal motion has been given, the EGR valve in a direction to decrease an opening of the EGR valve to a target EGR valve opening corresponding to a running condition to be reached after the accelerator pedal motion has been given. The control of the EGR valve opening is started before the fuel injection controller controls the fuel injector based on the target fuel injection amount calculated by the fuel injection amount calculator based on the accelerator pedal motion.

Proposed is a method and system for controlling an Exhaust Gas Recirculation (EGR) device in high-load driving, and an internal combustion engine vehicle including the system. The method of controlling an EGR device in high-load driving compares a ratio of pressures at a front end and a rear end of a throttle valve with a preset critical value that is a reference for determining high-load driving, performs Wide Open Throttle (WOT) control for fully opening the throttle valve when the ratio of pressures is larger than the preset critical value, determines whether engine torque due to the WOT control and use of EGR satisfies torque requested by a driver, and corrects throttle opening or stops use of EGR, depending on whether the engine torque due to use of EGR together with the WOT control satisfies the requested torque.

An electronic control method for a throttle by an electronic control throttle device that controls the throttle while an electronic control unit generates a control signal based on an input data signal. The method may include calculating an engine rotation speed deviation from a difference between an engine rotation speed and an input engine rotation speed command, calculating an engine rotational acceleration based on the engine rotation speed, obtaining a proportional torque from a product of the engine rotation speed deviation and a predetermined coefficient, obtaining an integral torque by integrating a value obtained by subtracting a product of the engine rotational acceleration and the predetermined coefficient from the product of the engine rotation speed deviation and the predetermined coefficient, and generating a control signal for the throttle by using a sum of the proportional torque and the integral torque as a value of a torque command.

The disclosed system and method changes a traction torque request in a vehicle powertrain with a driver-controlled vehicle accelerator pedal. A desired transfer function parameter in a powertrain control module is chosen by the driver to obtain a desired functional relationship between a traction torque request or a power plant torque request and accelerator pedal position.

A vehicle control system includes an acceleration generating device (engine, T/M) that generates an acceleration applied to a vehicle, and a vehicle control device that controls the acceleration generating device, based on an accelerator pedal stroke representing an operation of an accelerator pedal by a driver, and a vehicle speed of the vehicle. In the vehicle control system or method, the vehicle control device controls the acceleration generating device, based on a required acceleration that is determined based on a relationship between the accelerator pedal stroke and the required acceleration, including, as a condition, an acceleration corresponding to a given accelerator pedal stroke, which is specified by a relationship between the vehicle speed and the acceleration when the accelerator pedal stroke is held at the given value.

According to one embodiment, an apparatus for controlling fuel consumption in an internal combustion engine of a vehicle having a driver-actuated accelerator pedal includes an economy mode activation module and a standard fueling module. The economy mode activation module is configured to compare throttle input data with defined limits. The throttle input data is controllable by a driver of the vehicle via positioning of the accelerator pedal. The economy mode activation module is configured to control the fuel consumption of the internal combustion engine via an economy fuel map if the throttle input data falls within the defined limits for a defined amount of time. The standard fueling mode activation module is configured to control the fuel consumption of the internal combustion engine via a standard fuel map if the throttle input data does not fall within the defined limits for the defined amount of time.

A system comprising an engine and a controller configured to determine an air mass flow command to provide a target air mass flow value to the engine that is based on a base air mass flow value adjusted for engine operating conditions, deviations in the actual torque from a target torque, and corrected for flow conditions.
