摘要： An object of this disclosure is to provide a fuel injection device that can reliably detect an operation timing of a valve body, that is, a valve opening timing with high accuracy. The current of an electromagnetic valve reaches I2 at time t3, an FET 201 and an FET 221 are turned on, and a battery voltage VB is applied to the electromagnetic valve until time t5 is reached. The amount of displacement of the valve body reaches a target amount of control lift at time t4 between time t3 and time t5, that is, a movable core 304 comes into contact with a fixed core 301. The detection of the valve opening timing is performed during the period from time t3 to time t5.

摘要： Transmission shocks and idling defects such as engine racing and rough idling due to aging of a throttle opening area are prevented from occurring. An internal combustion engine control apparatus for controlling an internal combustion engine that has an air flow rate sensor for measuring a rate of air represented as an actual air rate, the air flowing into a cylinder, and a throttle valve for adjusting the rate of air, includes a throttle valve controlling section for controlling a throttle opening of the throttle valve to reach a preset throttle opening set depending on a target air rate for realizing a demand torque, and a throttle opening correcting section for correcting the preset throttle opening on the basis of the target air rate upon fuel cutoff that stops a fuel from being supplied to the internal combustion engine and of an actual air rate measured by the air flow rate sensor.

摘要： While a vehicle is coasting with an engine being automatically stopped and a power transmission path between the engine and wheels being disengaged, when a deceleration request is made and the engine is restarted with the power transmission path being engaged, a deceleration level increases relative to the deceleration level required by a driver or the vehicle, thereby lowering drivability. A vehicle control apparatus includes a deceleration level control unit that controls the deceleration level of the vehicle such that, during travelling of the vehicle continuing to travel with a power transmission mechanism between the engine and the wheels being disengaged, when the deceleration request is made and the engine is started by an engagement of the power transmission mechanism, the deceleration level becomes a target deceleration level calculated from a first target deceleration level generated after the engagement of the power transmission mechanism is complete and a second target deceleration level generated in response to the deceleration request.

摘要： In a vehicle control device for stopping an internal combustion engine when a vehicle is traveling at a predetermined speed or higher and a stop condition of the internal combustion engine is satisfied, fuel is injected to the engine even when the stop condition is satisfied, when an EGR rate of the internal combustion engine is equal to or higher than a set value. Alternatively, when the EGR rate is equal to or higher than the set value, an EGR valve attached to an EGR pipe of the engine is controlled in a valve closing direction when the stop condition is satisfied. Alternatively, when the EGR rate is equal to or higher than the set value, clutch engagement is maintained for a clutch control device that disconnects torque transmission between an output shaft of the internal combustion engine and a vehicle drive shaft, even when the stop condition is satisfied.

摘要： Introduction of a low fuel consumption technique such as downsizing turbos and idling stop decreases an intake pipe negative pressure (pump loss) of an internal combustion engine, and results in difficulty in emitting (evaporative fuel purge) a volatile fuel (volatile fuel) in a fuel tank by the negative pressure of the intake pipe of the internal combustion engine. A control device includes: a purge control unit which controls a purge valve which emits a volatile fuel of a fuel tank or a canister to an intake pipe of an internal combustion engine; and a power transmission control unit which controls a power transmission mechanism between the internal combustion engine and a drive wheel, and, in a state where the power transmission control unit disconnects a clutch, and the vehicle is coasting, the purge control unit opens the evaporative fuel valve and purges an evaporative fuel to the intake pipe.

摘要： In a constant-speed traveling mode or a follow-up traveling mode, reduction of fuel consumption and improvement of drivability are both achieved.An ECU 110 has an ISG connected to an engine and a battery connected to the ISG. The ECU 110 has an ISG control unit 606 that performs control for supplying power to the ISG from the battery to rotationally drive the ISG, or to drive the ISG to generate power for charging the battery. In one cycle of a traveling mode until completion of deceleration traveling after acceleration traveling is started so as to achieve a target vehicle speed, the ISG control unit 606 drives the ISG such that a remaining charge amount of the battery falls within a set range at completion of the deceleration traveling, and a traveling acceleration/deceleration falls within a predetermined requested acceleration/deceleration.

摘要： There is provided a vehicle-mounted control device that, when a restart request is generated during a time interval between the fulfillment of an engine automatic stop condition and complete stop, decreases a charging efficiency of an engine by means of at least one of a throttle valve and an intake valve to prevent an increase in the reverse rotational frequency of the engine, thereby ensuring the durability of the starting device of the engine, and preventing an accelerator response from deteriorating when a restart request based on the accelerator operation is generated. In the vehicle-mounted control device that controls a charging efficiency of the engine on the basis of the requested engine output amount, the engine is automatically stopped when a predetermined automatic stop condition is fulfilled, and a charging efficiency at the time when a restart condition of the engine has been fulfilled on the basis of an engine output request generated during a time interval between the fulfillment of the automatic stop condition and complete stop of the engine is made lower than a charging efficiency for the requested engine output amount.

摘要： An object of the present invention is to reduce discomfort of a driver, by appropriately controlling a vehicle, when driving a vehicle capable of changing a plurality of different traveling states of a power transmission state and a traveling state of an engine during traveling.The present invention is a vehicle control device for controlling a vehicle having a power transmission mechanism which controls a power transmission state between an engine and an axle, and braking means. The vehicle control device includes, as vehicle traveling states, a power transmission engine stop traveling state in which power is transmitted by the power transmission mechanism and fuel supply to the engine is stopped to cause the vehicle to travel, and a power shutoff brake traveling state in which power from the power transmission mechanism is shut off, the fuel supply to the engine is stopped, the braking means is controlled so that the braking force is smaller than the power transmission engine stop traveling state, and the vehicle is caused to travel.

摘要： An object is to provide a type of device capable of properly cooling a bearing of a throttle body even under a condition that the throttle body receives heat of high-temperature intake air or exhaust gas. In the present invention, an engine coolant passage that guides a coolant of an engine is provided integrally with a member fixing a bearing to be adjacent to a circumferential wall of the bearing of the member fixing the bearing, which supports a throttle shaft, and heat transferred from the bearing (or likely to be transferred to the bearing) via the member fixing the bearing is carried away to the outside of a throttle body by the engine coolant.
