Abstract: Provided is a vehicle signal light in which a person with protanopia (p-type color vision deficiency) can perceive whether or not the vehicle signal light, e.g., a stop lamp, a tail lamp, or the like, is turned on. The vehicle signal light includes a first light source configured to emit red light and a second light source configured to emit amber light. The first light source and the second light source are simultaneously turned on and are configured to emit light with a higher luminous intensity in response to a braking operation, and the emission intensity of the first light source is higher than that of the second light source.

Abstract: A vehicle driving apparatus includes an inverter which drives a permanent magnet motor. The inverter includes a three-phase bridge circuit including a plurality of switch elements, a drive circuit connected to the three-phase bridge circuit, a control circuit connected to the drive circuit, and an abnormality detecting unit which detects abnormality of the inverter. The drive circuit includes a three-phase-short-circuit-forming circuit which causes three phases of the permanent magnet motor to form short circuits, an abnormality accepting terminal which accepts an abnormality signal output from the abnormality detecting unit, and a check terminal which accepts an active check signal for causing the three-phase-short-circuit-forming circuit to perform three-phase short circuit control.

Abstract: A vehicle power supply system has a first switch, a second switch, a third switch, a fourth switch, a fifth switch, a sixth switch, a DC-DC converter, and a controller. In a case where power is supplied to both of a starter and an electrical component from any one of a first battery and a second battery, the controller causes power to be supplied to the electrical component via the DC-DC converter.

Abstract: A motor control device that controls the driving of a motor having a permanent magnet provided at a rotor has: an angle detector that detects the angle of the rotor by use of an angle sensor; a current detector that detects, as a detected current, the outflow current from or inflow current to a direct-current power source serving as the source for driving the motor; and an angle corrector that corrects the detected angle based on the detected current. The driving of the motor is controlled by use of a corrected angle obtained through the correction by the angle corrector.
