  • Patent number: 11415995
    Abstract: A control device includes an electronic control unit executes steering control for avoiding a collision with an object that has a possibility of colliding with a host vehicle. The electronic control unit sets a timing when the host vehicle is predicted to pass the object as an end timing of the steering control when the steering control is performed. The electronic control unit determines whether or not a deviation possibility is present when the electronic control unit assumes that the steering control ends at the end timing. The deviation possibility is a possibility of the host vehicle deviating from a current traveling lane accompanying an end of the steering control. The electronic control unit performs reduction processing that reduces the deviation possibility when the electronic control unit determines that the deviation possibility is present.

  • Patent number: 10775922
    Abstract: There is provision of an input device for calculating loads applied to multiple pressed points respectively, by executing one or more calculation loops in a load calculation unit. The calculation loop includes calculating computation values representing loads detected at load sensors based on initial pressed point loads, calculating a comparison value based on a comparison of the computation value with a detection value detected by the load sensor, calculating an adjustment value for adjusting the initial pressed point load based on the comparison values and pressed positions, and calculating the pressed point loads by adjusting the initial pressed point load based on the adjustment value. The load calculation unit uses the pressed point load calculated in the calculation loop for each of the pressed positions as an initial pressed point load in the next calculation loop.

  • Patent number: 9528461
    Abstract: To prevent a decrease in detection accuracy of an obstacle that occurs when an obstacle detection distance of an infrared beam at the center is set longer than an infrared beam of at least one of the left or the right, an obstacle detection device for a vehicle which detects an obstacle in front includes an effective-range control part 19 which controls the maximum effective distance of obstacle detection. The effective-range control part 19 extends the maximum effective distance of the second emitting-and-receiving parts 11b, 11c disposed on at least one of the left or the right from an initial value L1 to an extended value L2, when the first emitting-and-receiving part 11a at the center detects an obstacle 5.

  • Patent number: 8653836
    Abstract: A coordinate detecting device includes a plurality of first electrodes, a plurality of second electrodes, a capacitance detecting circuit, a first electrode switch, and a second electrode switch. All of the second electrodes are connected to a power supply by the second electrode switch and the first electrodes are selectively connected to the capacitance detecting circuit by the first electrode switch, thereby detecting a first coordinate. All of the first electrodes are connected to the power supply by the first electrode switch and the second electrodes are selectively connected to the capacitance detecting circuit by the second electrode switch, thereby detecting a second coordinate. When a plurality of first coordinates or a plurality of second coordinates are detected, capacitances between the first and second electrodes corresponding to combinations of the detected first and second coordinates are measured, thereby specifying the position of the detection target.
