20130151129VEHICLE CONTROL DEVICE AND VEHICLE CONTROL METHOD - A vehicle control device for controlling a vehicle includes a drive source control unit adapted to output a command for automatically stopping a drive source when a first predetermined condition is satisfied and output a command for restarting the drive source when a second predetermined condition is not satisfied after the command for automatically stopping the drive source is output, a drive source restart determination unit adapted to determine that the drive source has restarted when a third predetermined condition is satisfied after the command for restarting the drive source is output, and a restart determination prohibition unit adapted to prohibit a restart determination by the drive source restart determination unit at least until the third predetermined condition is no longer satisfied when the third predetermined condition is satisfied and the command for restarting the drive source is output.06-13-2013
20130151130IDLE REDUCTION CONTROLLER FOR ENGINE - When a vehicle speed is decreased to a first deceleration threshold value which is greater than zero, an idle reduction controller executes a first engine-shut-down to automatically shut down an engine. In a monitoring period from when the vehicle speed falls below a second deceleration threshold value which is greater than the first deceleration threshold value until when the vehicle speed becomes the first deceleration threshold value, when a steering operation is conducted by a driver, the first engine-shut-down is prohibited. Then, when the vehicle speed exceeds the second deceleration threshold value, a prohibition of the first engine-shut-down is canceled.06-13-2013
20120283935Method for Informng the Driver of a Vehicle Provided with a System for Automatically Stopping and Restarting the Engine in the Event an Automatic Stop is Unavailable - The invention relates to a method for informing, in a reassuring manner, the driver of a vehicle that is provided with a heat engine and a STT System for automatically stopping and restarting the engine. The method comprises the following steps: verifying that the driver requested the automatic engine stop; determining that the vehicle System does or does not allow the automatic stop; and if the automatic stop was properly requested and the vehicle System does not allow the automatic stop, informing the driver that not automatically stopping the engine is a normal operation.11-08-2012
20130158842CONTROL DEVICE AND CONTROL METHOD FOR ENGINE, AND VEHICLE - When a predetermined stop condition is satisfied, an engine is stopped. When a predetermined start condition is satisfied, a motor in a starter is driven and the engine is started. When a voltage of a battery for supplying electric power to the motor becomes lower than a threshold value while the motor is driven, stoppage of the engine is thereafter restricted. The threshold value increases as an engine rotation speed at the time when the motor is driven increases.06-20-2013
20130158843IDLE STOP CONTROL DEVICE, VEHICLE, IDLE STOP CONTROL METHOD, AND PROGRAM - A vehicle can reverse immediately after setting a no idling state in accordance with a simple operational procedure. An idle reduction control unit set the engine into a no idling state if the key switch is on, the brake is operated, the vehicle speed is zero, and the shift position is in the drive range; and restarts the engine if the braking operation is released and the shift position is in the drive range when the engine is in the no idling state. The idle reduction control unit also restarts the engine if the shift position is shifted from the drive range to the neutral range while the brake is still being operated when the engine is in the no idling state.06-20-2013
20130184975METHOD OF CONTROLLING ENGINE SHUT DOWN - A method of shutting down an engine determines whether an ignition key is in a first shutdown position. An exhaust gas recirculation valve closes when the ignition key is in the first shutdown position. The engine runs for a predetermined period of time after the exhaust gas recirculation valve is closed. The engine shuts down after running the engine for the predetermined period of time.07-18-2013
20110313643Internal Combustion Engine with Cylinders that can be De-Activated, with Exhaust Gas Recirculation by Variable Control of the Intake Valves, and Method for Controlling an Internal Combustion Engine - A multi-cylinder internal combustion engine is provided with a system for the variable actuation of the intake valves. At least one part of the engine cylinders is deactivated, cutting off fuel supply to said cylinders, under operating conditions that do not require the maximum power of the engine and in which one wants to reduce fuel consumption. The intake valves of the deactivated cylinders are kept at least partly open during at least one part of the discharge stages in the deactivated cylinders, hence, in the deactivated cylinders, part of the burnt gases generated during the operation prior to the deactivation flows into the respective intake conduits during the discharge stage of each cylinder. The intake valves are closed after the discharge stage. The intake valves of the deactivated cylinders are further kept closed during the compression and expansion stages in each deactivated cylinder.12-22-2011
20130197787ENGINE RESTART CONTROL DEVICE - There is provided an engine restart control device. A controller is configured to stop an engine which is adapted to generate a driving force for running a vehicle when a predetermined stop condition is met and configured to restart the engine when a predetermined restart condition is met after stopping the engine. A steering torque detector is configured to detect a steering torque of a steering wheel which is adapted to be operated by a driver. The controller includes an origin torque setting unit configured to set the steering torque detected by the steering torque detector when the predetermined stop condition is met and the engine is stopped as an origin torque. The controller restarts the engine when the steering torque detected by the steering torque detector exceeds a predetermined threshold with reference to the origin torque set by the origin torque setting unit.08-01-2013
20130204512ENGINE CONTROL APPARATUS PERFORMING AUTOMATIC ENGINE RESTART FOR ENSURING BRAKE BOOSTER ASSISTANCE AFTER AUTOMATIC ENGINE STOP - On a vehicle equipped with a vacuum-assist type of brake booster utilizing the intake air pressure of the vehicle engine, an engine control apparatus automatically stops the engine under certain conditions and subsequently automatically restarts the engine if it is determined that the brake booster pressure has fallen below a predetermined value. The engine control apparatus also effects such automatic restarting if a predetermined maximum time interval has elapsed since the automatic engine stop occurred. This ensures that even when the booster pressure value cannot be reliably obtained after an automatic engine stop has occurred, the engine will be restarted before the booster pressure falls excessively.08-08-2013
20120095670INTELLIGENT ENGINE IDLE STOP LOGIC - A method of controlling an internal combustion engine of a vehicle may involve turning on the internal combustion engine, stopping the vehicle or while the vehicle is approaching a known potential stopping location, inquiring whether a first predetermined quantity of data samples exists in memory and further inquiring whether the first predetermined quantity of data samples corresponds to a specific time of day, of a specific day of the week, of a specific month of the year, for a specific GPS location, inquiring whether a second predetermined quantity of data samples exists in memory for the specific time of any day of the week for the specific GPS location, inquiring whether a third predetermined quantity of data samples exists for any single, specific time of day for any day of the week for the specific GPS location. Depending upon the reply to each of the above inquiries, the method may include turning off the internal combustion engine.04-19-2012

20130211698SYSTEM AND METHOD FOR RESTARTING AN ENGINE - Various systems and methods are described for controlling an engine in a vehicle, the engine being coupled to a transmission. One example method comprises, under selected braking conditions, shutting-off the engine and spinning-down the engine to rest while the vehicle is traveling, and in response to a foot-off-brake event, restarting the engine by at least partially engaging the transmission to assist in spinning-up of the engine from rest while the vehicle is traveling. In this manner, vehicle inertia can be used to assist in spinning-up the engine from rest when the vehicle is moving.08-15-2013
