摘要： There was a problem that it was difficult for a semiconductor device in the related art to increase the switching frequency of a step-up circuit, and it was difficult to stabilize an output current and an output voltage. A semiconductor device controls a step-up circuit including an inductor and a drive transistor to drive the inductor. The semiconductor device calculates upper and lower limits which determine the variable range of an input current, based on an output current and an input voltage, controls the switch timing of the drive transistor based on the relation between the upper and lower limits and the magnitude of the input current, and at the same time, corrects the upper and lower limits to be calculated, based on the magnitude of the difference between the output current and a target output current value as an ideal value of the output current.

摘要： An autonomous vehicle is disclosed. The vehicle comprises a chassis, two or more drive wheels extending below the chassis, a drive motor housed within the chassis for driving the drive wheels, and a payload surface on top of the chassis for carrying a payload. An illumination system, for emitting light from at least one portion of the chassis, is mounted substantially around the entire perimeter of the chassis. The illumination system may be implemented using an array of light-emitting diodes (“LEDs”) that are arranged as segments. For example, there may be “headlight” segments on the front left and front right corners of the chassis.

摘要： The light source of the present disclosure spot-irradiates a distant place in front of a vehicle. The turn on/off circuit supplies a driving current ILD to the light source 120 to turn on the light source. The swivel mechanism swivels the light source. The turn on/off circuit reduces a light quantity of the light source as a swivel angle θ of the swivel mechanism is large.

摘要： The stabilization of a light-emitting diode (LED) calibration standard includes a light-emitting diode (LED), or an array of LEDs; a cylindrical hood surrounding the LED; an interior baffle for keeping the light output of the LED, and ambient light from behind the LED, from escaping to the other side; a photodetector for receiving the light output of the LED and generating a signal proportional to luminous output; and a hood surrounding the photodetector. A variable current source receives the signal and stabilizes the LED light output by adjusting the operating current of the LED to maintain a constant light output from the LED.

摘要： An in-vehicle load control system configured to controllably drive one or more loads on a vehicle according to an input signal. The system includes a first electronic control portion configured to perform signal processing based on the input signal, and a second electronic control portion configured to controllably drive the load. A backup signal channel is provided independently of a signal channel through which a signal is transmitted in a multiplex communication portion to input the input signal to the second electronic control portion. The second electronic control portion receives a first control signal via the signal channel in the multiplex communication portion and a second control signal via the backup signal channel, and controllably drives the load by preferentially treating the first control signal when the ignition signal is on and by preferentially treating the second control signal when the ignition signal is off.

摘要： A vehicle lighting unit can reduce the load applied to the actuator for driving a reflecting member as well as can improve the durability of the actuator. The vehicle lighting unit can include a light source, a reflecting member configured to reflect light from the light source toward an illumination area, an actuator including inner piezoelectric actuators and outer piezoelectric actuators configured to cause the reflecting member to swing (turn) around X and Y axes simultaneously, to thereby scan the illumination area with the reflected light from the reflecting member horizontally and vertically, and a controller configured to control the inner piezoelectric actuators and the outer piezoelectric actuators such that a scanning frequency in the vertical direction of the reflected light is larger than a scanning frequency in the horizontal direction of the reflected light.
