Abstract:
Downhill control and traffic congestion control are not started while a vehicle (10) is traveling on another traffic congestion section. After the vehicle (10) travels on the other traffic congestion section, downhill control or traffic congestion control is started only when the effect of improvement in fuel consumption resulting from downhill control or traffic congestion control is expected.
Abstract:
The purpose of the present invention is to prevent shock from occurring due to the intervention of regenerative control while operating in the four-wheel drive state. The drive source has a motor/generator (4), and an electronically controlled coupling (42) is provided on the drive power transmission path leading from the drive source to the front and rear wheels. This FF base four-wheel drive hybrid vehicle is comprising a 4WD control unit (85) that outputs to the electronically controlled coupling (42) a transmission torque command value to bring about the four-wheel drive state, in accordance with the vehicle state. The 4WD control unit (85) has a regenerative control intervention-coordinating controller that, when regenerative control by the motor/generator (4) has intervened during the four-wheel drive state, brings the transmission torque of the electronically controlled coupling (42) to zero before initiating regenerative control.
Abstract:
Die Erfindung betrifft ein Betriebsverfahren zur Steuerung eines motorischen Betriebs einer motorisch und generatorisch betreibbaren elektrischen Maschine eines Mild-Hybridantriebs eines Kraftfahrzeugs, wobei die elektrische Maschine dazu ausgebildet ist, einen Verbrennungsmotor des Kraftfahrzeugs zumindest zeitweise anzutreiben und in einem Rekuperationsbetrieb elektrische Energie zu erzeugen. Die Erfindung betrifft ferner eine Vorrichtung, die ausgebildet ist, das Betriebsverfahren auszuführen. Gemäß dem Betriebsverfahren wird eine Entscheidung, ob und/oder mit welcher Leistung ein motorischer Betrieb der elektrischen Maschine während der Fahrt durchgeführt wird, um mit einem motorischen Drehmoment den Verbrennungsmotor des Kraftfahrzeugs zu entlasten, in Abhängigkeit von momentanen Werten mindestens eines Betriebsparameters (21) des Kraftfahrzeugs und in Abhängigkeit von zurückliegenden Fahrbetriebsdaten (22) bestimmt. Auf diese Weise kann die Kraftstoffeinsparung des Mildhybridsystems durch Verwendung sonst nicht nutzbarer Energie erhöht werden.
Abstract:
A method for operating an engine and an integrated starter/generator/motor (ISGM) disposed in a hybrid electric vehicle, which includes launch and deceleration processes. The ISGM is used to both launch the vehicle and start the engine. The deceleration process includes operating a first clutch to disengage the engine from the ISGM during an initial phase, and engaging a second clutch during the initial phase to direct substantially all regenerative energy to provide the only source of electrical energy to recharge the energy storage device.
Abstract:
A hybrid vehicle (20) includes an electric control unit (70). A predictable condition is defined as a condition that the time period from beginning of a charging of a battery (50) to beginning of a rapid decrease in electric charging power is predicted to be within a specified time period. The electronic control unit (70) is configured to control a first electric motor (MG1) such that a motoring of an thermal engine (22) is performed at a first speed by the first electric motor (MG1) or motoring of the thermal engine (22) by the first electric motor (MG1) is prevented when the predictable condition is not satisfied. The electronic control unit (70) is configured to control the first electric motor (MG1) such that the motoring of the thermal engine (22) is performed at a second speed that is higher than the first speed by the first electric motor (MG1) when the predictable condition is satisfied.
Abstract:
Provided is a vehicle regenerative speed control device for suppressing undershooting, in which the actual transmission input rotational speed falls below a lower-limit rotational speed, when decreasing the transmission input rotational speed based on a request for a decrease in the regeneration amount during regenerative speed control. The present invention has a belt-type continuously variable transmission (6), a motor generator (4), and a main oil pump (14). The FF hybrid vehicle has a hybrid control module (81) which, when there is a request for an increase in the regeneration amount while decelerating, performs a regenerative speed control for downshifting the belt-type continuously variable transmission (6) to the low gear ratio side, and increasing rotational speed of a transmission input shaft to which the motor generator (4) is connected. The hybrid control module (81) also performs a control for making the rotational speed decrease change rate of the Pri end command rotational speed lower than the rotational speed increase change rate of the Pri end command rotational speed, when the Pri end command rotational speed is being decreased based on a request for a decrease in the regeneration amount during regenerative speed control.

In a hybrid vehicle including: a step-up converter (15) for stepping-up the voltage from a battery (8) and supplying power to the front motor (3) for driving front wheels; as well as a paddle switch (31) for setting regenerative braking torque stepwisely, and a hybrid control unit (20) for calculating a regenerative braking force based on a selection stage set by the paddle switch (31), the hybrid control unit (20) decreases the regenerative braking force to be less than the regenerative braking force while the maximum input/output power of the step-up converter (15) is not limited, when a selection stage in which regenerative braking force is more than that in a D range is selected while the maximum input/output power of the step-up converter (15) is limited.
