A coasting control method of an eco-friendly vehicle includes steps of acquiring deceleration event information and road gradient information in front of a vehicle during driving, by a controller in the vehicle, determining target vehicle speed in a deceleration event in consideration of road gradient based on the deceleration event information and the road gradient information, by the controller, determining expected vehicle speed while the vehicle is decelerated in a coasting state, based on current vehicle speed, by the controller, determining a start location for starting coasting based on target vehicle speed in consideration of current vehicle speed of the vehicle and the road gradient and expected vehicle speed at a target location as a deceleration event location, by the controller, and operating an information provider for coasting guidance and coasting induction to a driver at a start location, by the controller.

The present disclosure is related to hybrid vehicles. The teachings thereof may be embodied in vehicles as well as operation schemes meant to increase energy efficiency, such as a method comprising: detecting multiple consumption parameters of the hybrid vehicle; determining a future state of charge of a traction battery of the vehicle by mapping the consumption parameters onto a state-of-charge value, wherein the mapping includes classifying the multiple consumption parameters according to trainable class boundaries; training the class boundaries based at least in part on the detected consumption parameters and an associated measured state of charge; and adjusting an operating parameter of a traction power component of the hybrid vehicle according to the determined future state of charge.

A vehicle sailing stop control method is provided for a vehicle including a friction engagement element disposed between a traveling drive source and drive wheels, a torque converter disposed between the friction engagement element and the traveling drive source, and including a lock-up clutch for which a power transmission amount is controlled based on hydraulic pressure, and a hydraulic pressure source that can supply the hydraulic pressure while the traveling drive source is stopped. The vehicle sailing stop control method includes: performing sailing stop control so that coasting is performed by cutting off power transmission of the friction engagement element and stopping the traveling drive source upon a sailing stop travel condition being established; and, during coasting by the sailing stop control, placing the lock-up clutch in a power transmission state in which the hydraulic pressure is applied to the lock-up clutch.

Methods, systems, and apparatus for selectively learning and displaying information for a coasting guidance system. The system includes an electronic control unit (ECU) configured to determine a stop event location where a coasting guidance instruction is displayed. The system includes a memory configured to store one or more stop event locations. The system includes a display configured to display the stored one or more stop event locations on a map. The display is configured to receive an indication of a coasting guidance area on the map. The display is configured to identify a portion of the stored one or more stop event locations within the coasting guidance area. The display is configured to selectively display the portion of the one or more stop event locations on the map such that a stop event location outside of the coasting guidance area is absent from the map.

A method of controlling stability of a motorized vehicle having an electric motor as a drive source includes determining a slope of a road ahead, when sensing a sudden slope change point as a result of determination, determining a correction section based on the sudden slope change point, and correcting stability control torque in the correction section to compensate for motion of the vehicle body due to a change in the slope of the road using a pitching motion of the vehicle body caused by the torque of the electric motor.

Systems and methods for operating a driveline of a hybrid vehicle are disclosed. In one example, an engine may enter or stay in one of two cylinder deactivation modes or enter or stay in a combustion mode in response to a request to downshift a transmission while a vehicle in which the engine resides is coasting.

An object of the present invention is to provide a vehicle control apparatus and a vehicle control method capable of improving traceability when a speed reduction torque is applied. A vehicle control apparatus according to the present invention is configured to calculate the speed reduction torque to be generated on a vehicle based on an accelerator operation state and a front wheel slip angle. More specifically, when being brought into a turning state while a coasting torque is applied, the vehicle control apparatus makes a correction so as to reduce an absolute value of the coasting torque, thereby improving the traceability and the drivability.

A hybrid vehicle propulsion includes an engine and a first electric machine, where each is configured to selectively provide torque to propel the vehicle. The propulsion system also includes a second electric machine coupled to the engine to provide torque to start the engine from an inactive state. A high-voltage power source is configured to power both of the first electric machine and the second electric machine over a high-voltage bus. The propulsion system further includes a controller programmed to deactivate the engine and propel the vehicle using the first electric machine in response to the vehicle being driven at a steady-state speed for a predetermined duration of time. The controller is also programmed to restart the engine using the second electric machine powered by the high-voltage power source.

A first control unit executes a valve stop inertial running including stopping an intake valve and an exhaust valve in a closed state during rotation of an output shaft, stopping supply of fuel to an engine, and setting a clutch in an engaged state to drive pistons of the engine by a rotational force from driving wheels. A second control unit executes a valve operation running including operating the intake valve and the exhaust valve during the rotation of the output shaft, and supplying the fuel to the engine based upon an intake conduit pressure. When a cancellation request is made during execution of the valve stop inertial running, a transient control unit operates the intake valve and the exhaust valve, and controls a throttle valve to an idling opening or less, thereby supplying a negative pressure to an intake passage.
