Abstract

A contamination detection apparatus acquires distance-measurement point information from a laser radar apparatus that generates the distance-measurement point information that indicates a distance-measurement point distance to a distance measurement point and light reception intensity of detected laser light. The contamination detection apparatus acquires scattered light information that indicates scattered light intensity of scattered light from a scattered light sensor that detects scattered light generated by the laser light scattering inside the casing as a result of emission of the laser light by the laser radar apparatus. The contamination detection apparatus executes contamination detection that detects contamination of the optical window based on the scattered light intensity indicated by the scattered light information. The contamination detection apparatus prohibits execution of the contamination detection when the light reception intensity is equal to or greater than an intensity threshold set based on the distance-measurement point distance corresponding to the light reception intensity.

Abstract

In the present invention, an MG-ECU functions as a motor control device that controls a motor generator connected to an engine. Using a revolution speed detection value obtained by detecting the revolution speed of the motor generator, the MG-ECU performs feedback control so as to bring the revolution speed close to a command value, thereby causing the motor generator to output a damping torque in a phase reverse to that of torque variation in the engine. The MG-ECU switches the control gain of the feedback control between a plurality of levels including a low gain and a high gain. Furthermore, regarding a first transition (UT), in which transition is made from the low gain to the high gain, and a second transition (DT), in which a transition is made from the high gain to the low gain, a non-linear gain transition is implemented at least during the second transition (DT).

The second accommodating portion overlaps the rotating electrical machine when viewed in a direction perpendicular to both the vertical direction and the axial direction of the rotating electrical machine, and overlaps the output shaft when viewed in the vertical direction. The third accommodating portion is adjacent to the first accommodating portion and the second accommodating portion, and overlaps the output shaft when viewed in the vertical direction. At least a portion of the power module is disposed in the second accommodating portion or the third accommodating portion.
