  • Patent number: 11209081
    Abstract: A control apparatus for a linear solenoid valve configured to regulate a hydraulic pressure in a vehicle transmission. The control apparatus includes a hydraulic control portion configured to output a control command signal that is applied to a solenoid of the linear solenoid valve. The hydraulic control portion outputs, as the control command signal, a regulating control command signal by which the hydraulic pressure is to be regulated to a regulated pressure value that is dependent on a vehicle driving state. When the regulated pressure value is in a certain pressure range in which vibration-based noise is likely to be generated by vibration of the linear solenoid valve that is operated with the regulating control command signal being applied to the solenoid, the hydraulic control portion outputs, as the control command signal, a noise-restraining command signal by which generation of the vibration-based noise is restrained.

  • Patent number: 10962107
    Abstract: A control device for a vehicle includes an electronic control unit configured to perform an automatic driving control, to determine whether there is a possibility that a start control of an engine and a gear shift control of an automatic transmission are concurrently executed in a future traveling under the automatic driving control, during execution of the automatic driving control, and to first execute one control of the start control of the engine and the gear shift control of the automatic transmission in the future traveling and execute the other control after the one control finishes, when the electronic control unit determines that there is the possibility that the start control of the engine and the gear shift control of the automatic transmission are concurrently executed in the future traveling under the automatic driving control.
