  • Publication number: 20240151305
    Abstract: A vehicle includes a transmission which has a first oil pump driven by rotation of a drive source that drives a drive wheel and a second oil pump provided with a check valve on a suction side and driven by a motor. In a vehicle control device for controlling the vehicle, a minimum value of a drive current value of the motor is defined as a first current value, when the second oil pump is driven in a normal drive state, and a minimum rotation speed of the drive source is increased compared to a case in which the drive current value of the motor is equal to or larger than the first current value, when an automatic downshift control for automatically downshifting a speed ratio of the transmission is executed in a case in which the drive current value of the motor is smaller than the first current value when the second oil pump is driven.

  • Patent number: 4398948
    Abstract: Methods for controlling blowing, controlling the slag formation and predicting sloping in the blowing of molten pig iron in LD converter are carried out by measuring acceleration of the horizontal movement of a detector, such as a lance provided in the converter, which is caused only by the slag impinging against the lance, by an accelerator, integrating the measured values to obtain integrated average values at every several seconds, and programming the integrated average values in a computer.
