Abstract
The vehicle control apparatus gives a control current to the electromagnetic control valve at a start of energization of the electromagnetic control valve as a start current value smaller by a first determined amount than an open/closed state change-over reference current value which is necessary for changing over a state of the electromagnetic valve and after the start of energization of the electromagnetic control valve, the control current gradually increases with a smaller increase inclination than an increase inclination of an increase control of the control current which gives priority to a control responsibility of the electromagnetic control valve and finishes a gradual increase of the control current applying to the electromagnetic control valve, when the control current exceeds a finish current value which is larger than the open/closed state change-over reference current value.
