  • Patent number: 10569787
    Abstract: A driving support apparatus includes a driving support unit, a switching control unit, a reliability detection unit, and a threshold lowering unit. The switching control unit ceases driving support by the driving support unit and switches a driving state from driving in which the driving support is performed to manual driving, according to input from an operation detection unit when operating force or an operation amount exceeds a threshold. The reliability detection unit detects degradation of reliability of the driving support by the driving support unit. The threshold lowering unit lowers the threshold when the reliability detection unit detects the degradation of the reliability.

  • Patent number: 10573263
    Abstract: A driver IC is described by which disconnection can be readily prevented from being falsely determined even on condition that an input voltage fed back as a result of output of a detecting voltage by a driver IC is affected by noise on a driven device. The driver IC is arranged so that the latch timing of latching a result of the comparison between an input voltage fed back as a result of a detecting voltage output by the driver IC and the detecting voltage is shift-controlled in each predetermined cycle of synchronizing signals with a predetermined shift and even if noise is generated in a driven device at any time in each cycle of the synchronizing signals, determination signals affected by the noise are never latched in each cycle of the synchronizing signals.
