Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/004673
Kind Code:
A1
Abstract:
The present invention pertains to a vehicle control device which causes an electromagnetic valve 501 to be in an opened state by applying to the electromagnetic valve 501 a control current having a current value larger than a switching current value which is a current value set on the basis of the magnitude of the differential pressure between input and output ports of the electromagnetic valve 501. This vehicle control device is provided with: a control unit 11 that executes, in order to switch the electromagnetic valve 501 to the opened state from a closed state, valve-opening control for increasing the current value of the control current by a first current gradient up to a current value which is smaller than the switching current value by a first prescribed amount, and then increasing the current value of the control current by a second current gradient smaller than the first current gradient up until at least the current value of the control current exceeds the switching current value; and a setting unit 12 that sets the second current gradient to be smaller as the target change gradient of the differential pressure becomes larger.
