  • Patent number: 10444346
    Abstract: A pedestrian collision avoidance system for a vehicle including a radar sensor, a video camera, and an electronic control unit (ECU). The ECU detects an object in the video information and classifies the object as a pedestrian based on a comparison of the video information with a database. The ECU determines a distance to the pedestrian based on the radar information and determines a characteristic of the pedestrian based on the video information, the distance, and the database. When the pedestrian ceases to be detected by the radar sensor, the ECU determines an updated distance to the pedestrian based on the video information and the characteristic of the pedestrian. The ECU determines whether a potential for collision exists between the vehicle and the pedestrian based in part on the distance to the pedestrian, and when the potential for collision is present, the ECU activates an automatic vehicle response.

  • Patent number: 10429502
    Abstract: The target detecting device comprises a radar sensor, an imaging sensor, and an ECU. The target detected by the radar sensor is selected under certain conditions, for example, i) a reception intensity of the reflected radar waves is equal to or more than a predetermined value, or ii) the target is moving, to be outputted externally. When a stopped vehicle is detected on a road by the sensor, and a target, for example a pedestrian, present behind the stopped vehicle is detected from the image acquired by the imaging sensor by performing image recognition using predetermined patterns of a target, the ECU makes the selection condition less restrictive than the selection condition for targets other than the target present behind the stopped vehicle, or unconditionally selects the target present behind the stopped vehicle.

  • Patent number: 10393565
    Abstract: A method for determining a volume or a mass of a filling material is provided, in which firstly an empty profile detection mode is assumed in the absence of a filling material, and then a volume or mass determination mode is assumed when the filling material is present. In the empty profile detection mode, an interference point profile is created from echo curves obtained by scanning a container surface. The interference point profile is then taken into account when determining the volume or the mass of the filling material in the volume or mass determination mode, such that volumes or masses of the filling material are determined with increased accuracy.

  • Patent number: 10379224
    Abstract: A method for estimating the state of a moving system, using a particle filter. The method implements on one reference particle an estimation of the state and includes a first set of variables and a second set of variables. A random mutation, by the particle filter, of the first set of variables is performed followed by parameterization of an extended Kalman filter using the mutated first set of variables. The Kalman filter produces a new particle using the second set of variables and data measured by at least one sensor. The second set of variables includes at least the variables: orientation, speed and position of the moving system. The Kalman filter is configured assuming that the pair of variables orientation and position has a property of invariance upon a rotation or translation and their orientation and speed has a property of invariance on application of a rotation or translation.

  • Patent number: 10365348
    Abstract: Electronic devices and a method of providing electronic warfare (EW) data in an encapsulated architecture in a vehicle are generally described. Emitters targeting the vehicle during a mission may be detected and an observable history of each emitter obtained as a function of time. Properties of each emitter may be both inferred based on the observable history and extracted from locally-stored pre-mission intelligence. The emitter properties, as well as current and historical state and threat level of the emitter and effectiveness of various countermeasures may be stored in an adaptive radar model (ARM) for the emitter. Each emitter may have its own ARM. The ARM may be used to take appropriate countermeasures for a particular emitter, based on the emitter alone or taking into account all of the emitters.

  • Patent number: 10353050
    Abstract: A radar apparatus generates a spectrum distribution where frequencies in a beat signal are associated with intensities of respective frequency components. Based on a plurality of spectrum distributions generated over a predetermined number of measurement cycles prescribed in advance, the radar apparatus generates a reflection intensity distribution where frequencies are associated with road surface reflection intensities of the radar wave from a road surface at each frequency. In the reflection intensity distribution, the radar apparatus detects an intensity peak indicating a frequency that maximizes the road surface reflection intensity. Based on the detected intensity peak, the radar apparatus determines at least whether or not the radar apparatus is in an axis deviation state that is taken as a state where a reference axis of the radar apparatus has an inclination of not less than a prescribed angle in a vehicle height direction relative to a horizontal axis prescribed to a vehicle.
