TRW's Speed Proportional Steering Systems deliver excellent steering performance across the full range of steering assist requirements. Conventional power steering systems offer a compromise between full power steering effort at low speed and minimal power steering efforts at high speeds. Speed proportional steering eliminates the need for this compromise by providing more power steering during low speeds and parking maneuvers and less power steering assistance at high speeds providing more "road feel" and allowing for better directional stability and steering response.   Features Small & flexible package size •Possible combination with EPHS Integration in CAN bus system Open design for use of further parameters, e.g., yaw rate, front axle load, etc. Cartridge or bolt-on design Cut-off valve limits maximum steering torque Digital ECU including self diagnostics Safe handling enhanced  by optimum road contact & driver control at high speed Provides improved adaptation to vehicle character thru software programming of ECU
