  • Patent number: 11137852
    Abstract: A pressing operation detection device includes a pressing operation determination unit determining whether a pressing operation has been performed based on a touch on an operation unit and a pressing amount, an increase-and-decrease frequency detection unit detecting occurrence frequency of increase and decrease of a pressing amount every predetermined period of time, and a determination controller changing content of the determination process of the pressing operation determination unit based on the occurrence frequency detected while a touch on the operation unit is not detected. When a pressing amount is detected although the operation unit is not touched, assuming that increase and decrease of the pressing amount is caused by vibration, content of the determination process is changed such that influence of the vibration is reduced so that detection of a pressing operation which brings a feeling of strangeness to the user which is caused by the vibration may be avoided.

    Abstract: A spatial sensing region is set in accordance with a spatial sensing function of a first operation detection unit included in a first operation device, and another spatial sensing region is set in accordance with a spatial sensing function of a second operation detection unit included in a second operation device. The first operation device and the second operation device are arranged in a vehicle interior. For example, when the second operation detection unit of the second operation device detects a forward movement of a hand, it is determined that an operator intends to operate the first operation device and control is performed such that a display screen of the first operation device is turned on, for example.

    Abstract: A displacement measuring apparatus includes a plurality of reflective members disposed at a detection target such as a seat in a vehicle. A signal source and a transmitting antenna transmit a radio wave of a predetermined frequency that can pass through a human body to each of the plurality of reflective members, and a receiving antenna and a mixer receive the radio wave reflected by each of the plurality of reflective members and returned. A distance calculation unit calculates information on distances to the plurality of reflective members based on information on a time until the transmitted radio wave returns, and a displacement-distribution measuring unit calculates a displacement of each of the plurality of reflective members based on the information on the distances.

  • Patent number: 11127389
    Abstract: An active noise control unit generates a noise canceling sound of a single frequency that cancels engine sound heard by an occupant and outputs the noise canceling sound to a speaker through an amplifier. A second harmonic detector and a third harmonic detector detect a magnitude of a harmonic component of the noise canceling sound included in sound collected by a microphone. A controller controls a frequency of the noise canceling sound generated by the active noise control unit to a fundamental frequency of the engine sound based on a rotation frequency of the engine, and in addition, causes an output level control unit to control a level of the noise canceling sound to be output to the amplifier so that the level of the noise canceling sound becomes higher when the magnitude of the harmonic component exceeds a predetermined threshold value.

  • Patent number: 11118934
    Abstract: A method and system of route guidance for a vehicle alerts traffic restriction considering its towing status. The vehicle's towing status may be obtained either by automatically detecting a towed vehicle or manually setting such status by a user. When it is determined that the vehicle is towing another vehicle, traffic restriction information such as a speed limit and a dimension limit associated with each link in a route is obtained by accessing to a map database including such traffic restriction information. Based on the traffic restriction information, it is possible to provide the best route with a more correctly estimated time of arrival, while avoiding links which have dimension limits not suitable for the towing vehicle.

  • Publication number: 20210278907
    Abstract: When a gesture operation of a hand moving close to a display from left to right is performed, the return movement of the hand to the left side due to reflection by the wrist or the like may be detected. A detection control unit detects the approach of the hand to the display and notifies a data processing device of non-detection of hand approach when the amount of movement of the hand in the right direction starts to decrease after exceeding a threshold value. The data processing device accepts the right-moving gesture operation to perform a predetermined process when the amount of movement exceeds the threshold value.

    Abstract: Four infrared LEDs and two photodiodes PD are arranged below a lower side of a display surface in the order of an LED1, a PD1, an LED2, an LED3, a PD2, and an LED4. A detection signal A1 of the PD1 when the LED1 emits light, a detection signal A2 of the PD1 when the LED2 emits light, a detection signal A3 of the PD2 when the LED3 emits light, and a detection signal A4 of the PD2 when the LED4 emits light are used to estimate a reflection generation position in the left-right direction, and a threshold Th is set such that the threshold Th increases when the reflection generation position is on the left side, which is a driver's seat side. If the maximum value of A1, A2, A3, and A4 exceeds the threshold Th, the approach of the user's hand is detected.

  • Patent number: 11073931
    Abstract: In determining a definitive value, if a measured value detected at one timing changes by an amount less than a reference amount from a definitive value generated at a timing one cycle before the one timing, a definitive-value determination unit of a press detection apparatus determines the measured value detected at the one timing as a definitive value at the one timing, and if the measured value detected at the one timing has changed by an amount equal to or more than the reference amount from the definitive value at the preceding timing, the definitive-value determination unit determines a value obtained by adding the reference amount to the definitive value at the preceding timing as a definitive value at the one timing. This allows a value in which the influence of vibration is limited to be used in a determination of a pressing operation.

  • Patent number: 11043202
    Abstract: Two subsystems, each including a microphone, a speaker, a canceling sound-generating adder, an error-computing adder, and two adaptive filters and two auxiliary filters that accept two noises as input, are provided in correspondence with two cancellation positions. Each canceling sound-generating adder adds together the outputs from the adaptive filters and outputs the result to the speaker of each subsystem. Each error-computing adder adds together the output from the microphone of the subsystem and the output from the auxiliary filter of the subsystem, and the result is treated as the error of the adaptive filters of each subsystem. A transfer function is learned in advance and set in each auxiliary filter such that each error computed by each error-computing adder becomes zero (0) when a transfer function in which each noise is canceled at each cancellation position in a predetermined standard acoustic environment is set in each adaptive filter.
