A control device for opening and closing bodies of vehicles comprises a driving device that drives an opening and closing body of a vehicle and a controlling unit that controls operation of the driving device. The controlling unit is configured so as to cause the opening and closing body to move while controlling the speed of the opening and closing body movement by executing speed feedback control and to set a plurality of control regions over the range of movement of the opening and closing body and change control properties for the speed feedback control in each of the control regions.

Control device for opening and closing bodies of vehicles

One embodiment of the present invention provides a control device of a vehicle opening-closing member that includes a vehicle state determination unit that determines a traveling state of the vehicle based on a signal indicating a traveling state of a vehicle; an open/close state determination unit that determines an opening/opened state of the opening-closing member based on a signal indicating an opening/opened state of an opening-closing member provided to the vehicle; and a control unit that outputs a control signal for stopping an opening motion of the opening-closing member when it is determined by the vehicle state determination unit that the vehicle is in a state of traveling and when it is determined by the open/close state determination unit that the vehicle opening-closing member is in an opening/opened state.

Control device and control method of vehicle opening-closing member

An ultrasound sensor includes a transmitting/receiving device configured to transmit/receive ultrasound waves; and a controller configured to make the transmitting/receiving device transmit an ultrasound burst wave, as each of the ultrasound waves, and detect an object through a reception signal that is output from the transmitting/receiving device. The controller is configured to shift operation mode to a detecting mode, when the object is detected in a monitoring mode. In the monitoring mode, the number of waves included in the ultrasound burst wave is changed in two stages. The detecting mode is of detecting the object, using the ultrasound burst wave having the waves that are being used at a time point when the object is detected in the monitoring mode.

Ultrasound sensor

An ultrasonic sensor includes a transceiver device for transmitting and receiving ultrasonic waves; a circuit board mounted with an electronic circuit processing ultrasonic signals transmitted and received through the transceiver device; a housing including a device storing portion storing the transceiver device, a board storing portion storing the circuit board and a communication hole for bringing the device storing portion and the board storing portion into communication with each other, the board storing portion having an opening; and an electric connection unit extending through the communication hole to electrically interconnect the transceiver device and the circuit board. A cover member is installed in the opening of the board storing portion to hermetically seal the board storing portion.

Ultrasonic sensor

An ultrasonic sensor is provided at a bumperof a vehicleand used in a vehicle obstacle detectorthat detects the presence of an obstacle within a detection area by transmitting and receiving ultrasonic waves. The ultrasonic sensor includes a piezoelectric elementconfigured to transmit and receive the ultrasonic waves by using vibrations of a piezoelectric substrate and a plate-shaped acoustic matching layeron one surfaceof which the piezoelectric element is attached. The ultrasonic sensor is inserted in a mounting hole formed through the mounting surface. Another surfaceof the acoustic matching layeropposite to the one surfaceis inclined with respect to the one surfaceon which the piezoelectric element is attached, and is formed to be parallel with the outer surface of the bumper

An ultrasonic sensor includes a transceiver block having a transceiver device for transmitting and receiving ultrasonic waves and a circuit board mounted with an electronic circuit for processing ultrasonic signals transmitted and received through the transceiver device. A housing of the ultrasonic sensor has an opening and a communication hole, and the circuit board is stored into the housing through the opening. The transceiver block is attached to the housing. An electric connector extends through the communication hole of the housing to electrically interconnect the transceiver device and the electronic circuit of the circuit board; and a cover member closes the opening of the housing. The communication hole is sealed by a filler material.

An ultrasonic sensor that has a simplified structure, ensures high water resistance, and shortens the manufacturing time. An ultrasonic sensor includes a transducer, an electronic circuit substrate on which an electronic circuit is arranged to process an ultrasonic signal transmitted and received via the transducer, and a housing including a substrate retainer that retains the electronic circuit board. The substrate retainer includes a lid welded to an open portion thereof to hermetically seal the substrate retainer against the entry of a liquid.
