  • Patent number: 11305601
    Abstract: A control apparatus for a suspension apparatus includes: an acquisition section which acquires a stroke amount of the suspension apparatus disposed between a vehicle body and a wheel to damp vibration propagated from the wheel; a calculation section which calculates a stroke velocity based on the stroke amount; and a damping force control section which controls damping force of the suspension apparatus based on the stroke velocity. The calculation section includes a first calculation section which differentiates the stroke amount by use of a first time constant as a time constant, to thereby calculate a first stroke velocity, and a second calculation section which differentiates the stroke amount by use of a second time constant larger than the first time constant as a time constant, to thereby calculate a second stroke velocity, and calculates the stroke velocity based on the first stroke velocity and the second stroke velocity.

  • Publication number: 20200193174
    Abstract: A section line recognition device is realized which can determine a line type of a section line in a road surface with high accuracy. In step 301, a feature amount is extracted from an image captured by each camera. This step corresponds to a process of a feature point extraction unit. In the next step 302, the extracted feature amount is transformed into bird's-eye view coordinates which is common coordinates. This step corresponds to a process of a coordinates transformation unit. Next, in step 303, a camera to be selected is determined. This step is a process of a camera determination unit. Next, in step 304, the state transition at the appearance position of the feature point on the bird's-eye view coordinates is determined using feature point coordinates of the camera selected in step 303. This step is a process of a state transition determination unit. Finally, in step 305, the line type is determined. This step is a process of a line type determination unit.

  • Patent number: 10436610
    Abstract: An operation input detection device includes an operation input detection unit, a change amount accumulation unit, a section variation amount calculating unit, and a noise determination unit. The operation input detection unit detects an operation input on an operation input unit based on a sensor output of a capacitance sensor. The change amount accumulation unit accumulates a change amount of the sensor output in a determination section. The change amount of the sensor output is a difference of a detection value of the sensor output detected as each sampling timing from a previous value of the sensor output. The section variation amount calculating unit calculates a section variation amount of the sensor output.

  • Patent number: 10247587
    Abstract: An operation input detection device includes an operation input section, a capacitive sensor, an operation input detecting section, and a sensor calibration section, which executes calibration of the capacitive sensor. The sensor calibration section includes an irregular calibration section. The irregular calibration section executes the calibration if the sensor output that has changed in the same direction as when the object to be detected approaches the operation input section exceeds a first threshold value, and the sensor output subsequently changes in the opposite direction and exceeds a second threshold value set in the opposite direction within a predetermined time.

  • Patent number: 8712683
    Abstract: Conventional navigation devices are equipped with technology that supports the driving of a driver by detecting the surroundings of a vehicle using a plurality of sensors such as cameras. However, because complex arithmetic processing is carried out using the detection results from the plurality of sensors, the processing load increases and other processes requiring a rapid response can be delayed. As a result, consideration has been given to decreasing the amount of arithmetic processing and reducing the processing load by uniformly decreasing the processing area for information detected by the sensors. However, if the processing area is uniformly decreased, information necessary for driving support may not be obtained.
