Abstract: An operation device for a vehicle includes an operation body configured to be displaced by being operated so as to turn the vehicle according to a displacement of the operation body while the vehicle is being manually operated, a detector configured to detect the displacement of the operation body so as to turn the vehicle according to the displacement of the operation body while the vehicle is being manually operated, and a determination section configured to determine a state of the operation body and the detector based on the displacement of the operation body as detected by the detector while the vehicle is in non-manual operation.

Abstract: A correction system for a steering device that steers a steered wheel so that a steered angle of the steered wheel follows a steering angle of a steering wheel of a vehicle. The correction system includes a mode setting unit that sets the steering device to a correction mode for correcting the steering angle. An error calculation unit receives the detected steering angle and the detected steered angle in the correction mode when the steering wheel is rotated to calculate the difference between the steering angle and the steered angle and obtain a trigonometric waveform as an error of the steering angle. A correction unit corrects a parameter of the waveform so that the waveform become close to optimal.

Abstract: An autonomous driving device allows for autonomous driving of a vehicle. The autonomous driving device includes a monitoring unit and a switching unit. The monitoring unit monitors an operation state of a driving-system operation device of the vehicle. The switching unit switches a driving mode of the vehicle to manual driving, in which a user drives the vehicle, when the monitoring unit confirms that the driving-system operation device has been operated in accordance with a specified procedure under a condition that a vehicle speed is lower than or equal to a specified value.

Abstract: Provided is a light-emitting diode driving apparatus, including: a switching transistor which becomes an on-state or an off-state in response to a pulse width modulation signal; a light-emitting diode electrically connected with a second terminal of the switching transistor; a first comparison circuit which outputs a first voltage depending on a comparison result between a first input voltage corresponding to a voltage applied to the light-emitting diode and a first threshold voltage; a second comparison circuit which outputs a second voltage depending on a comparison result between a second input voltage corresponding to a voltage applied to the light-emitting diode and a second threshold voltage; and a signal processing circuit which detects a failure in the light-emitting diode on the basis of an output state of the pulse width modulation signal, the first voltage, the second voltage and a third voltage on the second terminal side of the switching transistor.
