A vehicle power steering motor (31) provides a force to turn vehicle steerable wheels (14 and 16). A power steering control valve (22) includes first and second relatively rotatable valve members (40 and 42). The first and second valve members (40 and 42) port fluid to actuate the vehicle power steering motor (31) upon relative movement. A device (114) senses at least one vehicle operational characteristic and provides a signal indicative of the at least one vehicle operational characteristic. In a preferred embodiment, the at least one vehicle operational characteristic is vehicle lateral acceleration. A force transmitting device (116, 120, and 130) resists relative movement between the first and second valve members (40 and 42) with a force which varies as a function of the output signal. The force varies as a function of vehicle lateral acceleration. <IMAGE>
