METHOD OF CONTROLLING ENGINE AND TRANSMISSION OF HYBRID VEHICLE
A method of controlling an engine and a transmission of a vehicle, which is a hybrid vehicle, includes the following steps that are carried out by a controller: determining whether the vehicle is under NCC (Neutral Coasting Control), determining whether an engine RPM reaches an engine RPM control point if it is determined that the NCC is in effect, determining an RPM and a gear stage of a vehicle transmission if it is determined that the engine RPM has reached the engine RPM control point, determining an engine target RPM of the vehicle, determining whether the engine RPM has reached a mild hybrid starter & generator (MHSG) control point, and controlling the MHSG according to a condition if it is determined that the engine RPM has reached the MHSG control point.
SITUATIONAL DEACTIVATION OF LANE KEEP ASSIST SYSTEM
A method for controlling a lane keep assist system comprises the combination of predicting that a driver may initiate a lane change without using a turn indicator switch and temporarily deactivating the lane keep assist system in response to such prediction.
ELECTRIC VEHICLE
An electric vehicle includes a vehicle controller. The vehicle controller is capable of switching a traveling mode of the electric vehicle between a first traveling mode and a second traveling mode that applies driving-force maps for enhancing a rough-road capability from a rough-road capability in the first traveling mode. The vehicle controller is capable of switching the traveling mode to the second traveling mode in forward traveling and in backward traveling and is configured to apply, to the backward traveling in the second traveling mode, a first driving-force map of the driving-force maps, the first driving-force map having gentler characteristics than a second driving-force map of the driving-force map applied to the forward traveling in the second traveling mode.
METHODS AND SYSTEM FOR IMPROVING HYBRID VEHICLE EFFICIENCY
Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods provide different ways to transition engine operating conditions between two low engine fuel consumption operating regions that are separated by a higher engine fuel consumption operating region. In one example, engine torque is increased at a higher rate in a fuel economy mode to increase an amount of time an engine operates in one of the two low fuel consumption operating regions.
SYSTEMS AND METHODS FOR CONTROLLING CYLINDER DEACTIVATION OPERATION IN ELECTRIFIED POWERTRAINS
At least some embodiments of the present disclosure are directed to systems and methods for controlling a cylinder deactivation (CDA) operation for an electrified powertrain, the electrified powertrain comprising an engine and an additional power source, the engine having a plurality of cylinders. The method includes the step of: operating the electrified powertrain in a CDA mode and deactivating one or more selected cylinders of the plurality of cylinders; receiving measurement data indicative of operating conditions of the electrified powertrain; analyzing the measurement data to determine whether a predetermined operating condition is met; and adjusting the CDA operation by adjusting the duration of the CDA operation or changing a number of deactivated cylinders.
SUPPLEMENTAL ELECTRIC DRIVE WITH PRIMARY ENGINE RECOGNITION FOR ELECTRIC DRIVE CONTROLLER ADAPTATION
Through-the-road (TTR) hybrid designs using control strategies such as an equivalent consumption minimization strategy (ECMS) or an adaptive ECMS are implemented at the supplemental torque delivering electrically-powered drive axle (or axles) in a manner that follows operational parameters or computationally estimates states of the primary drivetrain and/or fuel-fed engine, but does not itself participate in control of the fuel-fed engine or primary drivetrain. BSFC type data particular to the paired-with fuel-fed engine allows an ECMS implementation (or other similar control strategy) to adapt to efficiency curves for the particular fuel-fed engine and to improve overall efficiencies of the TTR hybrid configuration.
Vehicle state prediction system
A state predicting circuitry predicts a route showing a future change in the vehicle state from among a plurality of routes from a first node to a second node. The first node corresponds to the current vehicle state. The second node corresponds to the vehicle state after having transitioned a predetermined number of times from the first node. The state predicting circuitry predicts a route in which at least one of an accumulated value of the node that exists in the routes and an accumulated value of the link that exists in the routes is greatest, from among the plurality of routes.
IN-VEHICLE DYNOMETER
A hydraulic system is adapted to provide at least one of a fluid flow at a variable fluid pressure or a fluid flow at a variable fluid displacement. A pressure sensor measures a fluid pressure. A controller is in communication with the engine and the pressure sensor. Wherein, the controller sends an engine speed signal to operate the engine in an open state and controls the fluid displacement or the fluid pressure of the hydraulic system to a first load condition. Further wherein, the controller detects an engine speed and a fluid pressure of the hydraulic system with the pressure sensor when the engine is in the open state and the hydraulic system is in the first load condition. Further wherein, the controller operably calculates a total engine torque as a function of the detected engine speed and fluid pressure when the hydraulic system is in the first load condition.
