  • Patent number: 11933234
    Abstract: An engine is provided with a turbo charger including a wastegate valve. A first setpoint of opening of the wastegate valve is set in accordance with a target boost pressure. While a difference between the target boost pressure and a real boost pressure is large, the opening is controlled to a second setpoint, wherein the second setpoint is smaller than the first setpoint. While the opening is controlled to the second setpoint, it is determined whether a condition for limitation is satisfied in which an intake air quantity is above an intake air quantity criterion and an engine rotation speed is above an engine rotation speed criterion. When the condition is satisfied, the opening is controlled in a direction to increase from the second setpoint. The engine rotation speed criterion decreases as the intake air quantity increases. The intake air quantity criterion decreases as the engine rotation speed increases.

    Abstract: A voice analyzer analyzes whether a voice signal input into a voice input unit includes a specific characteristic component. A voice recognizer recognizes a voice represented by the voice signal input into the voice input unit. A response instruction unit instructs a response to a response operation unit that operates in response to the voice recognized by the voice recognizer. A controller controls the voice recognizer not to execute voice recognition processing by the voice recognizer or controls the response instruction unit not to instruct the response operation unit about an instruction content by the voice recognized by the voice recognizer, when the voice analyzer analyzes that the voice signal includes the specific characteristic component.

  • Patent number: 11919569
    Abstract: An aluminum cast part of a motor vehicle includes at least two upper walls rising from a bottom wall to form a passage, and at least two lower walls extending the upper walls beyond the bottom wall. The upper and lower walls form, with the bottom wall, a cross-section transverse to the passage which is generally H-shaped. In one or more predetermined cross-sections, at least one upper inner rib extends inside the H and transversely to the upper walls and the bottom wall, at least one outer rib extends outside the H to form an extension of the upper inner rib, and at least one lower inner rib extends inside the H to form an extension of the upper inner rib. A height of the upper inner rib in a central area of the H is compensated for by a height of the lower inner rib in the central area.

  • Patent number: 11921506
    Abstract: Real-time decision-making for a vehicle using belief state determination is described. Operational environment data is received while the vehicle is traversing a vehicle transportation network, where the data includes data associated with an external object. An operational environment monitor establishes an observation that relates the object to a distinct vehicle operation scenario. A belief state model of the monitor computes a belief state for the observation directly from the operational environment data. The monitor provides the computed belief state to a decision component implementing a policy that maps a respective belief state for the object within the distinct vehicle operation scenario to a respective candidate vehicle control action. A candidate vehicle control action is received from the policy of the decision component, and a vehicle control action is selected for traversing the vehicle transportation from any available candidate vehicle control actions.

    Abstract: A vehicle data display system includes an electronic display installed within a vehicle, a 3-D sensor and an electronic controller. The 3-D sensor configured to scan areas forward of and along lateral sides of the vehicle producing point cloud. Each data point of the cloud data corresponding to a surface portion of a physical feature. Each data point includes distance, direction and vertical location of each surface point. The electronic controller is connected to the electronic display and the 3-D sensor. The electronic controller receives and evaluates the point cloud from the 3-D sensor generating a 3-D model of detected ones of the physical features around the vehicle including ground surfaces, non-drivable features and driving limiting features relative to the vehicle. The non-drivable features are features that have predetermined geometric relationships with adjacent ground surfaces such that caution is to be taken when driving over or on driving limiting features.

  • Patent number: 11913400
    Abstract: During a predetermined operation state in which the opening degree of a throttle valve is fixed, an air flow meter positioned more on the upstream side than a pressure control valve detects a first intake air amount when the opening degree of the pressure control valve positioned on the upstream side of the throttle valve is set to a predetermined first valve opening degree and a second intake air amount when the opening degree of the pressure control valve is set to a predetermined second valve opening degree smaller than the first valve opening degree. On the basis of the first intake air amount and the second intake air amount, a diagnosis is made regarding whether there is an abnormality in a first pipe, a second pipe, a third pipe and the like which are included in a blow-by gas recirculation system for blow-by gas treatment.
