  • Publication number: 20240152026
    Abstract: A quantum absorption spectroscopy system (1) includes a pump light source (11), a quantum interferometer (21), and a spectroscope (31). The pump light source (11) emits pump light. The quantum interferometer (21) causes quantum interference between a plurality of physical processes in which a quantum entanglement photon pair of a signal photon and an idler photon is generated through spontaneous parametric down-conversion of the pump light, a sample being arranged on a propagation path of the idler photon. The spectroscope (31) detects a signal photon from the quantum interferometer (21). The quantum interferometer (21) includes a single mode fiber (SMF) portion optically coupled to at least part of a propagation path of the signal photon and the propagation path of the idler photon.

    Abstract: A vehicle front recognition apparatus includes an imager that captures an image of an environment ahead of a vehicle on the road, an image analyzer that analyzes the image of the environment with artificial intelligence to segment the image areas of the image by classes to which objects captured in the image belong, and a road information acquirer that acquires high-precision map information ahead of the vehicle. The vehicle front recognition apparatus acquires dynamic information that is not included in the high-precision map information from the classes. The image analyzer includes a feeling-of-strangeness area extractor extracting a feeling-of-strangeness area using the classes from the image areas. The vehicle front recognition apparatus further includes a feeling-of-strangeness area verifier that verifies whether the vehicle can pass through the feeling-of-strangeness area and a notifier that notifies a driver when the vehicle cannot pass through the feeling-of-strangeness area.

    Abstract: A vehicle drive assist apparatus is to be applied to a vehicle. The apparatus includes an object recognizer, a risk area setter, a risk level setter, a route candidate setter, a route evaluation value calculator, and a vehicle travel route setter. The object recognizer recognizes an object in front of the vehicle. The risk area setter sets, when small objects are around the object, a risk area including the small objects. The risk level setter sets a risk level for the risk area based on a distribution state of the small objects within the risk area. The route candidate setter sets patterns of route candidates for avoiding a risk resulting from the risk area. The route evaluation value calculator calculates a route evaluation value for each of the route candidates. The vehicle travel route setter sets, as a vehicle travel route, the route candidate having an optimum route evaluation value.

  • Publication number: 20240034315
    Abstract: A surrounding environment around a vehicle is recognized and surrounding environment information is acquired. Traveling control is performed on the vehicle based on the acquired surrounding environment information. When an obstacle expected to hinder traveling of the vehicle is recognized ahead of the vehicle and other vehicles traveling ahead of the vehicle are recognized in an adjacent lane adjacent to a traveling lane where the vehicle is traveling, a movement amount of the obstacle moved due to an effect of a first other vehicle among the other vehicles that travels at a position near the obstacle is detected. An estimated movement amount of the obstacle moved due to an effect of a second other vehicle among the other vehicles that follows the first other vehicle is calculated based on the detected movement amount. The traveling control is performed on the vehicle based on the estimated movement amount.

  • Publication number: 20230234571
    Abstract: A vehicle drive assist apparatus to be applied to a vehicle executes at least emergency braking control for avoiding collision of the vehicle with a recognized object. The vehicle drive assist apparatus includes a surrounding environment recognition device and a traveling control unit. The surrounding environment recognition device includes a recognizer that recognizes a surrounding environment around the vehicle, and a feature information acquirer that acquires feature information of a target object in the recognized surrounding environment. The traveling control unit centrally controls the entire vehicle. The traveling control unit includes a determiner that determines, based on the acquired feature information, whether the target object has a possibility of hindering traveling of the vehicle. The traveling control unit continues normal traveling control for the vehicle when the target object is determined to have no possibility of hindering the traveling of the vehicle.

  • Publication number: 20230227025
    Abstract: A surrounding environment recognition device recognizes a surrounding environment around a vehicle. A traveling control unit centrally controls a whole of the entire vehicle. An obstacle presumer presumes presence of an obstacle ahead of the vehicle based on a behavior distribution of preceding vehicles recognized by the surrounding environment recognition device, and estimates a position and an area where the obstacle is present when the presence of the obstacle is presumed. A traveling path calculator calculates candidates for traveling path areas along which the vehicle is expected to travel while avoiding collision with the presumed obstacle. A traveling path selector selects a traveling path area from among the calculated traveling path areas and sets the selected traveling path area. The traveling control unit controls the vehicle to travel along the set traveling path area.

  • Patent number: 7150256
    Abstract: Air is aspirated by cylinders of cylinder rows (11, 12) via branch pipes (23,24) from two intake collectors (21,22) of a V type multi-cylinder internal combustion engine. An auxiliary chamber (31, 32) is formed using the space between adjacent branch pipes (23,24). A communication port (25, 26) to the intake collector (21,22) of the auxiliary chamber (31,32) is formed between the openings (23A,24A) to the intake collector (21,22) of two adjacent branch pipes (23,24). Since the effective volume of the intake collector (21,22) increases due to the auxiliary chamber (31,32), residual resonance in the intake collector (21, 22) decreases. The auxiliary chamber (31,32) increases an intake inertia effect by increasing the flow rate of the branch pipes (23,24) in the second half of the intake stroke relative to the flow rate in the first half of the intake stroke. Engine volume efficiency is thereby improved using a limited space.
