  • Publication number: 20260054727
    Abstract: When the preceding vehicle is stopped in front of the traffic light, the lighting color of the traffic light is “green”, the other vehicle is not stopped immediately before the preceding vehicle, the direction indicating light of the preceding vehicle is off, and the distance between the host vehicle and the preceding vehicle at the time when the preceding vehicle is detected exceeds a threshold value, the processor controls the predetermined device so that the host vehicle travels at a constant speed, or controls the predetermined device of the host vehicle so that the speed of the host vehicle decreases in the second mode that is slower than the first mode.

  • Publication number: 20250206305
    Abstract: The processor controls the drive device and/or the braking device to execute either a mild deceleration process or an acceleration suppression process in the following situations: In the first specific scene (SCN1), where the own vehicle and the preceding vehicle PV are traveling on the leftmost lane or a left-turn lane of a general road composed of multiple lanes, or on a single-lane general road, and the turn signal of the preceding vehicle PV is indicating a left turn, while the preceding vehicle PV is not decelerating. In the second specific scene (SCN2), where the own vehicle and the preceding vehicle PV are traveling on the rightmost lane or a right-turn lane of a general road composed of multiple lanes, or on a single-lane general road, and the turn signal of the preceding vehicle PV is indicating a right turn, while the preceding vehicle PV is not decelerating.

  • Patent number: 12208482
    Abstract: A cutting apparatus includes a chuck table configured to hold the workpiece, and a cutting unit fitted with a cutting blade including an annular base and a cutting edge that includes abrasive grains and a binder configured to fix the abrasive grains, and is formed along an outer circumferential edge of the base. The cutting unit includes a spindle, a blade mount fitted to a distal end portion of the spindle, and a fixing nut configured to fix the cutting blade to the blade mount, and the blade mount or the fixing nut is provided with a corrosion layer formed of a material having a higher ionization tendency than a material constituting the binder.

  • Publication number: 20240208503
    Abstract: The driving support device includes a deceleration control unit, a branch path detection unit, an operation state acquisition unit, and a steering state acquisition unit. The deceleration control unit determines whether the driver intends to change the path in the branch path based on the operation state of the direction indicator and the steering state of the steering wheel, when the deceleration control unit detects that a branch path exists in front of the host vehicle during execution of the deceleration control of the host vehicle with respect to the preceding vehicle, and when the driver determines that there is an intention to change the branch path, the deceleration control of the host vehicle with respect to the preceding vehicle is ended.

  • Patent number: 11932247
    Abstract: A device according to the present disclosure is configured to, when it is determined that the road on which a vehicle travels is an uphill road and the speed of the vehicle is controlled such that the vehicle follows a preceding vehicle, in a case where the preceding vehicle is no longer detected, inhibit the acceleration of the vehicle or decelerate the vehicle until it is determined that the road on which the vehicle travels is no longer the uphill road, or alternatively, until a certain period of time elapses.

  • Patent number: 11229986
    Abstract: An annular grindstone includes a grindstone portion including a binding material, and abrasive grains which are dispersed into the binding material to be fixed, in which the binding material contains a nickel-iron alloy. Preferably, a contained ratio of iron in the nickel-iron alloy is in a range of 5 wt % or more to less than 60 wt %. More preferably, a contained ratio of iron in the nickel-iron alloy is in a range of 20 wt % or more to 50 wt % or less. Preferably, the annular grindstone includes the grindstone portion only. In addition, the annular grindstone further includes an annular base including a grip portion, in which the grindstone portion is exposed at an outer peripheral edge of the annular base.
