Abstract
An electronic control systemis provided for independent actuation of a plurality of hydraulic actuatorsThe electronic control systememploys an electronic driverconnected to a first parallel circuit or first low side driverand a second parallel circuit or second low side driverEach parallel circuitcontains a first and a second actuator LLrespectively, connected in series to a first and a second low side MOSFET Qand Qrespectively. Pulse width modulation of the electronic driverin conjunction with selective actuation of either low side driverresults in rapid response to system control algorithms whereby each actuator Lor Lmay be de-activated in a relatively quick manner thereby improving vehicular control.
