  • Publication number: 20240396454
    Abstract: In a power conversion apparatus, first to xth converters are connected in parallel to each other. A control unit outputs, based on command information related to an output of the power conversion apparatus, control information. A pulse generator selects, based on the control information, a number n of converters from the first to xth converters, n being an integer more than or equal to 2 and smaller than x. The number n is defined as a multiply-driven number n. The pulse generator generates, based on the control information, at least one multiple drive-pulse train that comprises n drive pulses for multiply driving the n selected converters. A variable determiner changes the multiply-driven number n.

  • Patent number: 9020727
    Abstract: A vehicle braking assist device for a host vehicle includes a risk potential computing part that computes a risk potential of the host vehicle with respect to an obstacle in the travelling direction of the host vehicle, an accelerator operation state sensor that detects the operation state of an accelerator, and a braking force application device that applies a first braking force on the host vehicle when the risk potential is higher than a predetermined first threshold and the detected operation state of the accelerator indicates that the accelerator is not being operated, and that applies a second braking force on the host vehicle irrespective of the operation state of the accelerator when the risk potential is higher than a predetermined second threshold, the risk potential represented by the second threshold being higher than the risk potential represented by the first threshold.

  • Patent number: 8996294
    Abstract: An inter-vehicle distance maintenance supporting system for a host vehicle can include an obstacle detector that detects the obstacle present ahead of the host vehicle, an inter-vehicle distance detector that detects the inter-vehicle distance between the host vehicle and the obstacle, a confidence factor computing device that computes the confidence factor for taking the obstacle as a preceding vehicle ahead of the host vehicle based on the state of the obstacle detected by the obstacle detector, a confidence factor correcting part that corrects the confidence factor based on the relative-position relationship between the host vehicle and the obstacle, and a reaction force controller that applies a reaction force on the accelerator pedal based on the inter-vehicle distance and the confidence factor.

  • Patent number: 6220874
    Abstract: A wire harness assembly including a wire harness and a junction box. The junction box contains a plurality of junction box terminals and it also carries an attachment unit projecting outwardly. The attachment unit has a plurality of openings in its outer surface through which the junction box terminals project. One end of the terminals is in contact with the internal circuit of the junction box and the other is a pair of cutting blades into which the wire is inserted. An intermediate section of the wires is attached in accordance with the foregoing, and the ends are inserted into a plurality of connection boxes. The openings may be in multiple rows, offset transversely from each other. This permits inclusion of a large number of terminals in a relatively small space.
