  • Publication number: 20200255016
    Abstract: A vehicle control device includes an operation detection unit that detects an operation input performed by a user to an operation input unit, to which a first operation input to instruct activation or termination of a predetermined function and a second operation input to instruct suspension of the predetermined function can be performed, and a lane change control unit that controls a lane change on the basis of the operation input performed by the user in response to the lane change proposal issued in a state where the predetermined function is operating. The lane change control unit carries out the lane change in the case that the first operation input is performed by the user in response to the lane change proposal, and does not carry out the lane change in the case that the second operation input is performed by the user in response to the lane change proposal.

    Abstract: A control system for an internal combustion engine, which is capable of quickly and properly ensuring excellent fuel economy of the engine even when atmospheric pressure has changed. The control system includes an ECU. The ECU performs weighted average calculation on lowland map values and highland map values, based on atmospheric pressure, to thereby calculate map values of a demanded torque that minimize a fuel consumption ratio of the engine in the atmospheric pressure, and calculates engine demanded output. The ECU calculates demanded torque and demanded engine speed using the map values and the engine demanded output, respectively. The ECU controls the engine using the demanded torque.

  • Patent number: 9925976
    Abstract: A hybrid electric vehicle drive apparatus has a setting portion for setting a limit value of a driving torque that a motor outputs when driving a hybrid electric vehicle by the power of the motor only, based on a maximum torque that the motor enables to output and a starting torque used to start an internal combustion engine by the motor. The setting portion sets the limit value to a first value and sets the limit value to a second value which is greater than the first value when a vehicle speed of the vehicle does not increase even though an accelerator pedal position degree increases while the vehicle is being driven only by the motor.

  • Patent number: 9284897
    Abstract: An intake control system for an internal combustion engine, which, even when there are a plurality of intake air amounts for attaining one target torque, is capable of positively selecting a minimum intake air amount therefrom without causing hunting, and setting the minimum intake air amount as a target intake air amount, thereby making it possible to improve fuel economy. The intake control system calculates a maximum intake air amount, sets a plurality of provisional intake air amounts within a range of 0 to the maximum intake air amount, calculates torques estimated to be output from the engine with respect to the provisional intake air amounts, respectively, selects a minimum provisional intake air amount that makes the estimated torque equal to or close to the target torque from the relationship between the provisional intake air amounts and the estimated torques, and sets the same as the target intake air amount.

  • Patent number: 9273616
    Abstract: An intake control system for an internal combustion engine is capable of ensuring a differential pressure across an EGR valve, and controlling an EGR amount with high accuracy. A target fresh air amount is set based on a demanded torque calculated according to operating conditions of the engine. A differential pressure across an EGR valve is set as a target differential pressure. When it is determined that the across-valve differential pressure is not in a state in which the target differential pressure can be ensured, an opening degree of the EGR valve is controlled to limit an EGR amount. An opening degree of a throttle valve is controlled based on the target fresh air amount, so as to ensure the target differential pressure.

  • Patent number: 8275539
    Abstract: A control system for an internal combustion engine, which is capable of preventing a variable valve-operating mechanism from suffering problems due to insufficiency of lubrication oil immediately after starting the engine. The ECU of the engine determines an amount of lubrication oil lubricating the variable valve-operating mechanism which is capable of continuously changing an intake lift, holds the intake lift at a predetermined lift if it is determined that the oil amount is less than a predetermined amount, and controls the amount of intake air by changing the opening of a throttle valve capable of adjusting the amount of intake air, when the operation of the variable valve-operating mechanism is inhibited.

  • Patent number: 8271180
    Abstract: An intake control system for an internal combustion engine, which is capable of suppressing a change in an intake pressure caused by a change in a target intake air amount even in a transient operating condition in which the target intake air amount is varied, thereby making it possible to control the intake pressure stably and accurately. The intake control system controls an intake air amount by an intake valve lift, and controls intake negative pressure by a throttle valve. The system limits a target intake air amount based on upper and lower limit values set according to the intake valve lift and an intake cam phase, and corrects the target intake air amount by averaging the same using averaging calculation such that the change therein is delayed. A throttle valve opening is set according to the corrected target intake air amount.

  • Patent number: 7953529
    Abstract: The present invention provides a scheme for determining an abnormality of an intake air system with higher accuracy in an engine an intake air amount is controlled by adjusting a lift amount of an intake valve. A throttle opening area is determined based on a current intake air amount. A feedback correction is performed on the throttle opening area. The feedback correction includes determining a correction amount of the throttle opening area such that the gauge pressure inside the intake manifold converges to a desired gauge pressure and then adding the correction amount to the throttle opening area. A feedback control is performed on an air-fuel ratio. The feedback control includes determining a correction amount of the air-fuel ratio based on a detection value of an air-fuel ratio detecting means provided in an exhaust manifold.

  • Patent number: 7877192
    Abstract: A rotational speed parameter is detected in accordance with a rotational speed of the engine. A reference value of the rotational speed parameter is calculated. For each cylinder, an error between the reference value and the rotational speed parameter detected every predetermined crank angle is calculated as a relative speed parameter. For each cylinder, an integrated value is calculated by integrating the relative speed parameters over a predetermined period. For each cylinder, an average value per cylinder of the sum of the integrated values of all the cylinders is calculated. For each cylinder, an error between the integrated value of the cylinder and the average value is calculated. For each cylinder, the output of the engine is controlled in accordance with the error calculated for the cylinder such that variations in the output between the cylinders are suppressed.
