If a vehicle speed is less than a predetermined value when a hybrid control mode is a series mode and a charge mode is selected (S10-S14), it is determined whether an SOC of a high voltage battery is less than a predetermined value or not (S16), and when the SOC of the high voltage battery is less than the predetermined value, ignition timing is corrected to be retarded (S18).

Methods and systems are provided for introducing a charge motion to a cylinder via a protrusion system coupled to an intake port of an engine. In one example, a system may include positioning a tongue from inside a spring-loaded casing to extend into air intake runner, generating desired tumble and swirl along an intake port proximate to an engine cylinder.

A system according to the principles of the present disclosure includes a pedal position prediction module and an engine actuator control module. The pedal position prediction module predicts a pedal position at a future time based on driver behavior and vehicle driving conditions. The pedal position includes at least one of an accelerator pedal position and a brake pedal position. The engine actuator control module controls an actuator of an engine based on the predicted pedal position.

A method is provided for operating a vehicle, in particular a watercraft, with at least one combustion engine that emits pollutants contained in an exhaust gas or wastewater. The current position of the vehicle is determined by a location determination. A closed-loop and/or open-loop control device is provided which sets or adjusts the quantity of at least one pollutant emitted by the combustion engine in a self-acting manner or automatically, in accordance with the determined position of the vehicle and with information on local pollutant regulations, in particular exhaust and/or water regulations.

Rolling engine start-stop (RESS) system and methods for a vehicle include a set of sensors configured to measure a set of operating parameters of the vehicle comprising at least (i) driver input via brake pedal of the vehicle, (ii) vehicle speed, and (iii) a steering angle of the vehicle and a controller configured to, based on the set of operating parameters, determine a target vehicle speed for stopping an engine of the vehicle, and based on the steering angle of the vehicle, selectively stopping the engine of the vehicle when the vehicle speed falls to the determined target vehicle speed, wherein stopping the engine of the vehicle at the determined target vehicle speed decreases noise/vibration/harshness (NVH) caused by stopping the engine.

A method of controlling an idle speed for an engine of a vehicle includes the steps of sensing a vehicle speed and a parking brake position. Clutch position is also sensed. When it is determined that the vehicle speed is below a maximum vehicle speed, the parking brake is released, and the clutch is depressed, the engine idle speed is increased from a base idle speed to a launch idle speed.

The present invention relates to a vehicle supercharger assembly (14) comprising a generator comprising a first armature (14) being adapted for permanent drive from a source of motive power; a supercharger impeller (24) arranged to be driven via a gear train; an electric motor comprising a second armature (28), said second armature (28) being coupled to the gear train; a first clutch (32) for selectively coupling the first armature (14) to the gear train for driving the supercharger impeller (24) in a first mode of operation in which the electric motor is operable to adjust the speed of the supercharger impeller (24); and a second clutch (34), operable when said first armature (14) is coupled to the gear train, for selectively locking the gear train so as to prevent relative rotation of the first and second armatures in a second mode of operation.

A variable displacement controller for deactivating one or more cylinder assemblies of a vehicle engine can include a processor for performing various operations and the operations can include: receiving data indicative of a requested torque and vehicle speed, determining a torque variable timer threshold value based on the received data indicative of requested torque and vehicle speed, initiating a timer, comparing the timer value to the variable timer threshold value, and selectively activating/deactivating at least one of the engine cylinder assemblies based on the comparison between the timer value and the variable timer threshold value. At least one of the engine cylinder assemblies is activated if the timer value is less than the variable timer threshold value, and at least one of the engine cylinder assemblies is deactivated if the timer value is greater than or equal to the variable timer threshold value.

A method of maintaining a temperature of an aftertreatment system of a vehicle, the method including: operating, by a controller, a retarder reducing driving force of a propeller shaft of the vehicle in response to a retarder operation request signal; operating, by the controller, a jake brake device which discharges a fuel-air mixture compressed in an explosion stroke of the engine to an exhaust pipe and decreases revolutions per minute (RPM) of the engine or an exhaust brake device which blocks a discharge of the exhaust gas of the engine to a rear end of the exhaust pipe and decreases the RPM of the engine, in order to remove the output error value; and controlling, by the controller, the engine so that an amount of exhaust gas introduced into the aftertreatment system is decreased.

A vehicle includes a transmission, a torque converter coupled to the transmission, a controller in communication with the transmission and the torque converter; a driver seat, a passenger seat, and a back seat coupled to the transmission, and sensors configured to detect occupancy of the seats. The sensors are in communication with the controller. The controller is programmed to receive data from the sensors, determine an occupancy status based on the occupancy data, set an engine operating parameter of one of the transmission and the torque converter based on the occupancy status, and control one of the transmission and the torque converter to operate according to the parameter.
