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:
A start-stop system for a motor vehicle is provided. the start-stop system being configured to control the operation of an engine of the motor vehicle when a predetermined engine start-stop condition is achieved, wherein the start-stop system is configured to shut down the engine according to an operating condition of the start-stop system, wherein the operating condition is one of: a first condition, in which the start-stop system is prevented from shutting down the engine of the motor vehicle when one or more critical inhibitors are active; and a second condition, in which the start-stop system is prevented from shutting down the engine of the motor vehicle when one or more critical or non-critical inhibitors are active. A motor vehicle comprising the start-stop system and a method of operating the motor vehicle are also provided.
Abstract:
When a permission condition which is set in advance is satisfied in a state in which a vehicle is stopped by an operation of a brake pedal by the driver, an engine mounted on the vehicle is automatically stopped; and when the engine is automatically stopped, while a vehicle stop maintaining control to generate a braking force capable of maintaining a stop state of the vehicle is operated even when a brake operation is reduced, there is started notification to the occupant of the vehicle about ignition information which indicates that a state of an ignition switch of the vehicle is on when a parking brake is operated.
Abstract:
In a drive control device, a controller automatically stops an engine if an execution condition of an idling stop is satisfied, and an electric oil pump is driven during an automatic stop of the engine. A first friction engaging element establishes a starting gear position and a second friction engaging element is released when a vehicle starts. A second solenoid drains oil to be supplied to the second friction engaging element according to an indicator current. A drain degree becomes smaller by reducing the indicator current. The controller reduces the indicator current below a minimum value during the automatic stop of the engine.
Abstract:
There is provided with an automatic transmission (2) having a clutch (32) and a brake device (6) which holds a brake force during a stop of an engine (1). There is provided with an engine control section (11) which performs an automatic stop of the engine and a re-start of the engine and a release control section (14) which releases a holding of the brake force during the re-start of the engine. The release control section (14) releases the holding of the brake force when an engagement state of the clutch (32) is a predetermined state in case where an accelerator off state occurs until the engagement state of the clutch (32) becomes the predetermined state and releases the holding of the brake force when the engagement state of the clutch (32) is an engagement state weaker than the predetermined state, during a re-start of the engine (1).
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:
The idle stop control device includes charge control means (46) for increasing and reducing a power generation amount of an ACG starter (18) in accordance with a charge state of a battery (19), and engine output control means (47) for controlling output of the engine (14a). When it is determined that stopping the engine by idle stop control is not suitable based on a charge state detected by charge state detecting means (41), the idle stop control device increases the power generation amount of the ACG starter (18) by the charge control means (46). When charging reinforcing control for increasing the power generation amount of the dynamo is executed by the charge control means (46), in response to this, the engine output control means (47) executes output increasing control for increasing, more than usual, the output of the engine (14a) with respect to the operation amount of the throttle grip (5).
Abstract:
In a vehicle with a driving power source (an engine, a motor generator, or a similar component) to output driving power for running to a driving wheel, in a case where a restart is requested on the driving power source in an accelerator-on state after a stop operation is performed on the driving power source (a hybrid system) during running of a vehicle, the driving power corresponding to an accelerator position at the time of restart request is not directly output. Instead, the driving power is output to the driving wheels while being gradually increased. This reduces deterioration of drivability in recovery of the driving power.
