  • Publication number: 20210263149
    Abstract: An object detection device includes a drive signal generation unit provided to generate a drive signal for driving a transmitter configured to transmit a search wave to the outside, and a control unit provided to control output of the drive signal from the drive signal generation unit to the transmitter. The drive signal generation unit generates a first drive signal corresponding to a first search wave and a second drive signal corresponding to a second search wave having an encoding scheme that is different from the encoding scheme of the first search wave. The control unit causes the drive signal generation unit to output the first drive signal and the second drive signal to the transmitter at different timings so that one of the first and second search waves is transmitted in a transmission interval between transmissions of the other search wave.

  • Publication number: 20200049816
    Abstract: An object detection device which determines an amplitude Ar of an ultrasonic wave received by a receiving unit, detects a frequency fr of the ultrasonic wave, sweeps a frequency fp of a pulse signal after a predetermined time has elapsed from start of generation of the pulse signal, and determines that the received ultrasonic wave is a reflected wave of the probe wave when the frequency fr after the amplitude Ar becomes a predetermined reference value or more from start of transmission of the probe wave makes the same change as the frequency fp. When an ultrasonic wave received by a receiver is determined to be a reflected wave of the probe wave, the object detection unit calculates a distance to an object based on a time from transmission of the probe wave to reception of the ultrasonic wave.

  • Patent number: 10465719
    Abstract: A hydraulic excavator (1) includes a wireless authentication device (52) performing wireless authentication with a portable key device (51) and a vehicle body controller (48) for starting an engine (15) based on authentication by the wireless authentication device (52) and an operation of a start switch (12). The wireless authentication device (52) transmits a request signal within an authenticable range and performs authentication when it receives an ID code for authentication replied from the portable key device (51) based on the transmitted request signal. The vehicle body controller (48) prohibits driving of a hydraulic actuator (5E, 5F, 5G, 5H, 2E, 2F, 3A) when the portable key device (51) is outside of the authenticable range even if a gate lock lever (13) has been switched to an unlock position.

  • Patent number: 10415702
    Abstract: In a parking lock system, a link member that swings due to sliding of an operating shaft so as to make a perking lock operate and release the operation includes a counterweight for canceling out axial inertial force of the operating shaft. Therefore, even if the operating shaft attempts to slide in an axial direction with respect to a transmission case due to inertial force when a vehicle experiences sudden deceleration due to a frontal collision or sudden braking, mass of the counterweight resists the inertial force to thus prevent the link member from swinging, thereby making it possible to avoid a situation in which the parking lock is operated unintentionally.
