  • Patent number: 10174719
    Abstract: In a non-EGR region that is a light load operating region, an EGR control valve (21) is opened at a predetermined infinitesimal opening degree M that corresponds to such infinitesimal EGR ratio as not to affect an ignition timing. With this control, since an EGR passage (20) is basically in a state in which the EGR passage (20) is filled with EGR gas, when an operating condition is changed from the non-EGR region to an EGR region and the EGR control valve (21) is opened so as to gain a target EGR ratio, a desired quantity of the EGR gas is introduced into an intake passage (2) substantially at the same time as the opening of the EGR control valve (21). An actual EGR ratio can thus follow the target EGR ratio with a good response.

  • Patent number: 10175144
    Abstract: An actual gear ratio change amount (?Gr) is calculated by subtracting a pre-shift gear ratio (Gb) from an actual gear ratio (Gr). A gear ratio (G) is calculated by multiplying the actual gear ratio change amount (?Gr) by a predetermined coefficient (C) and adding the product value to the pre-shift gear ratio (Gb). When the shift is an upshift, the gear ratio (G) is compared with aa target gear shift ratio (Ga), and the greater value is set as a virtual gear ratio (Gv). When the shift is a downshift, then the gear ratio (G) is compared with the target gear ratio (Ga) and the smaller value is set as the virtual gear ratio (Gv). A virtual input shaft rotational speed (Nv) is calculated by first dividing the actual gear ratio (Gr) by the virtual gear ratio (Gv) to obtain a quotient and by dividing the actual input shift rotational speed (Nr) by that quotient.

  • Patent number: 10160446
    Abstract: A hybrid vehicle control device for controlling a hybrid vehicle with an engine and an electric motor as drive sources of the vehicle includes a high-load road travel determination unit configured to determine whether or not the vehicle is traveling on a high running resistance road surface on which a predetermined vehicle acceleration is unobtainable only by an output of the engine, and a motor output setting unit configured to set an output of the electric motor. If the vehicle is determined to be traveling on the high running resistance road surface by the high-load road travel determination unit, the motor output setting unit limits the output of the electric motor when a vehicle speed reaches a predetermined vehicle speed.

  • Patent number: 10163016
    Abstract: A parking space detection method detects a parking space in an empty state from a captured image acquired by a camera configured to capture an image of a parking lot. The method includes detecting a parked vehicle existing in a parking space on the far side from the subject vehicle and adjacent to a determination target parking space for which the empty state is determined and measuring a lateral length of the parked vehicle on a surface located at the side of the determination target parking space. When the lateral length is a predetermined value or more, the determination target parking space is detected as a parking space in the empty state.

  • Patent number: 10160348
    Abstract: A starting control device is provided for an electrically driven vehicle having an electric motor and an internal combustion engine as drive sources and a transmission shifts and transmits an output of the electric motor to a drive wheel. The starting control device is configured to suppress an abrupt increase in the rotation of the electric motor at the time of an EV start of the vehicle from a released state of a starting dog clutch. In the electrically driven vehicle, an EV start is carried out by transmitting the output of the first motor/generator (MG1) to the drive wheel via a starting dog clutch that is meshingly engaged. The output of the first motor/generator is limited until the starting dog clutch comes into a meshed state in which the transmission transmits drive power at the time of start from a released state of the starting dog clutch.
