Abstract
To avoid placing an unnecessary load on a prime mover, a pump control arrangement monitors automotive vehicle speed and inhibits an increase in pump output above a basic estimate when the vehicle speed is below a predetermined level. If the speed falls below the level while the pump output is above the basic estimate, the present operating mode is maintained for a given period before being reduced to the basic estimate level.
