Internal combustion engine control device
Provided is an internal combustion engine control device capable of appropriately correcting a flow rate of EGR gas. Therefore, an internal combustion engine control device 20 includes moisture amount calculation units 301 and 302, a dew condensation calculation unit 303, and an EGR correction unit 304. The moisture amount calculation unit 301 calculates a total moisture amount contained in the mixed gas. The dew condensation calculation unit 303 calculates a dew condensation generation amount WQcon in an intercooler based on the total moisture amount. The EGR correction unit 304 corrects a flow rate of the EGR gas based on the dew condensation generation amount WQcon.
Vehicle control apparatus and vehicle control method
A vehicle control apparatus that makes it possible to attempt fuel consumption improvement and exhaust gas reduction effectively without causing a sense of incompatibility in the driver is provided. When traveling following the preceding vehicle, kinetic energy required for an own vehicle in future is predicted on the basis of kinetic energy of the own vehicle, a velocity of a preceding vehicle, and a distance between the own vehicle and the preceding vehicle. It is determined whether there is kinetic energy enough for the own vehicle to be able to follow the preceding vehicle with inertial traveling, on the basis of the predicted kinetic energy and current kinetic energy. When it is determined that the kinetic energy is sufficient and the driving and traveling state of the own vehicle satisfies other traveling idling reduction conditions, control of stopping the engine is exercised.
Systems and methods for predictive and automatic engine stop-start control
In some embodiments of the present disclosure, sensors mounted on a vehicle can allow opportunities for coasting to be predicted based on environmental conditions, route planning information, and/or vehicle-to-vehicle or vehicle-to-infrastructure signaling. In some embodiments of the present disclosure, these sensors can also predict a need for power and/or an end of a coast opportunity. These predictions can allow the vehicle to automatically enter a coasting state, and can predictively re-engage the engine and/or powertrain in order to make power available with no delay when desired by the operator.
VEHICLE CONTROLLING DEVICE AND VEHICLE HAVING THE SAME
A vehicle controlling device comprises: a VSA-ECU which controls deceleration of a host vehicle using an inter-vehicle distance between the host vehicle and another vehicle running ahead of the host vehicle; and an engine controller which performs idling stop control to stop drive of an engine as a driving power source of the host vehicle when a stop condition, inclusive of an entry of a vehicle speed of the host vehicle into a predetermined low vehicle speed range, is satisfied, and which performs restart control to restart the engine when a predetermined restart condition is satisfied. A power supply mounted on the host vehicle is used in common as a power supply used for the deceleration control and a power supply used for the restart control. While the idling stop control is on, the VSA-ECU disables execution of the deceleration control of the host vehicle using the inter-vehicle distance.
Vehicle control unit
The present invention relates to a vehicle control unit (20). The vehicle control unit (20) comprises an input (26) for detecting a start demand and a driving condition. The vehicle control module also comprises a control module (28) arranged to control an engine start attribute according to a first profile (34) and a second profile (36). The vehicle control module (20) also comprises a selection module (30) arranged to select between the first and second profiles (34, 36) based on detecting a predetermined driving condition, in response to detecting a start demand.
Using cognitive analysis with pattern templates to compose engine mapping mix settings
Race car settings (e.g., Formula 1 engine mix settings) are developed for particular racing goals such as faster lap time, better acceleration, less vehicle wear, etc., using pattern templates that are derived from historical racing scenarios. The historical scenarios provide data on racing settings, racing results, and racing conditions such as squad information, equipment information, and environmental information. A cognitive (deep question answering) system can select an initial pattern template based on current racing conditions, and present suggested vehicle settings to the user (driver) using the initial pattern template. The driver can select from different candidate values for various factors, which may lead to the presentation of additional suggestions or the use of additional pattern templates. The final settings map is created based on the employed pattern templates and the driver selections.
METHOD AND SYSTEM FOR ENGINE CONTROL
Methods and systems are provided for enabling turbocharger shaft speed control without overfilling a system battery. In one example, shaft speed is reduced by applying a negative torque from an electric boost assist motor until a system battery has been sufficiently charged. Thereafter, electrical power from shaft braking is recuperated by commanding a positive torque onto a driveline of the vehicle via a BISG.
Method for testing a moisture sensor of a diesel engine
A method for testing a moisture sensor of a diesel engine includes: measuring, by an NOx sensor, an untreated NOx emissions content in exhaust gas of the diesel engine upstream of a Selective Catalytic Reduction (SCR) catalytic converter at particular steady-state operating points in a defined window, to obtain an actual concentration value of NOx emissions; determining an oxygen concentration in intake air from an intake pipe of the diesel engine, and converting the result obtained from the determination, by a characteristic curve, into an NOx concentration to obtain a model value of NOx concentration; comparing the actual value with the model value; and identifying a faulty condition of the moisture sensor if a deviation that exceeds a set value (R) is detected between the actual and model values.
METHODS AND SYSTEMS FOR CONTROLLING ENGINE IDLE-STOP
Methods and systems are provided for controlling an engine idle-stop based on upcoming traffic and road conditions. In one example, a method may include receiving data including traffic information and road characteristics immediately ahead of a vehicle from one or more remote sources, and adjusting one or more vehicle thresholds based on the received data. A duration of a prospective engine idle-stop may be estimated based on the received data and an engine idle-stop may be initiated based on the duration of the prospective engine idle-stop and the adjusted one or more vehicle threshold.
SYSTEM AND METHOD FOR VARIABLE COMPRESSION RATIO ENGINE
Methods and systems are provided for improving calibration of a variable compression ratio engine. Cylinder-to-cylinder compression ratio variations are detected and accounted for by comparing cylinder fuel flow and IMEP at each compression ratio setting. Dilution parameters including EGR and VCT schedule are also calibrated to account for the cylinder-to-cylinder compression ratio variations.
