EHPS, short for Electro-hydraulic Power Steering, is a technology that falls between traditional hydraulic power steering and pure electric power steering.
Traditional HPS: Its hydraulic pump is directly driven by the engine via a belt. As long as the engine is running, the pump operates continuously, consuming energy. This is one reason why the steering wheel is heaviest, and fuel consumption increases when traditional gasoline-powered cars are idling.
EHPS: It replaces the engine with a dedicated electric motor. This electric motor is specifically designed to drive the hydraulic pump, thereby generating hydraulic power steering.
