Abstract: A vehicle control device performs predetermined control on a vehicle by communicating with a portable device held by a user. The Vehicle control device includes: a living body sensor that detects whether or not a living body is present in the vehicle by acquiring biological information of the living body; an output device that outputs an alarm; and an alarm output determination unit that determines the alarm to be output by the output device by detecting the presence of the living body in the vehicle by the living body sensor and satisfying a predetermined condition for outputting the alarm. When the portable device and the vehicle control device communicate with each other after the alarm is output by the output device, the output device stops outputting the alarm.

Abstract: A biological information output device eliminates data having a value equal to or greater than a predetermined value from data obtained from an electromagnetic wave reflected on a body surface and acquires data having a value less than the predetermined value; specifies a frequency peak in a predetermined period of the acquired data; creates a histogram by adding an occurrence frequency at which the frequency peak appears for each different class as a frequency while defining a prescribed frequency range where the specified frequency peak exists as one class; and determines, when a frequency of a class having the frequency which is a maximum occurrence frequency among classes in the histogram exceeds a predetermined threshold value, the class as an initial value of biological information. The biological information output device extracts the biological information from the data based on a cycle specified by the determined initial value.

Abstract: A control device includes a first system and a second system being a redundant system for the first system, and controls a device to be controlled. The control device includes a first abnormality detector detecting abnormality of a first-system circuit constituting the first system, and a second abnormality detector detecting abnormality of a second-system circuit constituting the second system. The first abnormality detector detects existence of abnormality of the first-system circuit by comparing the detected value of a first predetermined part of the first-system circuit with a first threshold. The second abnormality detector detects existence of abnormality of the second-system circuit by comparing the detected value of a second predetermined part in the second-system circuit corresponding to the first predetermined part, with a second threshold different from the first threshold.

Abstract: Provided is a motor control device that includes a controller outputting a PWM control signal for controlling a multiphase electric motor, a driving signal generator generating a switching element driving signal for driving the multiphase electric motor according to the PWM control signal output from the controller, and a bridge circuit configured of a plurality of semiconductor switching elements switching a current flowing through the multiphase electric motor according to the switching element driving signal generated by the driving signal generator. The controller is provided on a first board. The driving signal generator and the bridge circuit are provided on a second board and are connected by wiring provided on the second board. The first board and the second board are connected by a predetermined inter-board connecting line. The controller outputs the PWM control signal to the driving signal generator through the predetermined inter-board connecting line.
