Abstract: In a vehicle control device for controlling the vehicle, when automatic downshift control for automatically downshifting a speed ratio of the transmission is executed in the case where a drive current value of the motor obtained when the second oil pump is driven is larger than a maximum value of the drive current value of the motor obtained when the second oil pump is driven in a normal drive state, the vehicle control device increases a minimum rotation speed of the drive source compared to a case where the drive current value of the motor is equal to or less than the maximum value, and when the automatic downshift control is executed in the case where a line pressure generated by a hydraulic pressure supplied from the first oil pump and the second oil pump is larger than a predetermined value, the vehicle control device does not increase the minimum rotation speed of the drive source even in the case where the drive current value of the motor obtained when the second oil pump is driven is larger than the m

Abstract: [Problem] To provide an ultrasonic physical properties measurement device that suppresses the generation of a secondary flow inside a cylinder, is more portable, and can suppress changes in physical properties. [Solution] An ultrasonic physical properties measurement device 1 that: uses ultrasonic waves to measure the flow velocity profile of fluids that flow inside a cylinder 2, by rotating the cylinder 2 backwards and forwards in a fixed cycle; and calculates the physical properties of fluid from the flow velocity profile. The cylinder 2: has an upper end surface 21 and lower end surface 22 that are penetrated such that fluid can flow therethrough; and comprises a rotation mechanism 3 that supports all or part of the cylinder 2 in a state of immersion in the fluid and rotates the cylinder 2 backwards and forwards.
