What kind of vehicles require electric power steering pumps?
To understand which vehicles require an Electro-Hydraulic Power Steering (EHPS) pump, one must first look at the system's characteristics. Simply put, it is a device that uses an electric motor to drive a hydraulic pump, thereby providing assistance to the steering system.
It is most essential for vehicles that lack an internal combustion engine yet require significant steering effort. Traditional hydraulic power steering relies on an engine-driven belt; since pure electric vehicles do not have an engine to drive this setup, an electrically driven solution like EHPS is required to fill the gap.
Specifically, these primarily include the following types of vehicles:
--New Energy Commercial Vehicles: Vehicles such as all-electric buses, logistics trucks, and sanitation vehicles are inherently heavy, requiring significant steering effort. Standard EPS (Electric Power Steering) lacks the necessary torque, whereas EHPS (Electro-Hydraulic Power Steering)-which utilizes hydraulic assistance-is robust enough to handle the load.
--Heavy Passenger Vehicles or SUVs: These vehicles are also heavy and demand substantial steering assistance. EHPS provides stronger assistance than EPS while dynamically adjusting the level of aid based on vehicle speed, offering light steering at low speeds and stability at high speeds for a more intuitive driving experience.
--Models Upgrading from Traditional Hydraulic Steering: Some vehicles originally equipped with HPS (Hydraulic Power Steering) are being converted to new energy powertrains without the manufacturer wanting to redesign the entire steering system. EHPS allows for the direct retention of the existing hydraulic steering gear; only the power source needs to be switched from the engine to an electric motor, resulting in minimal modifications and lower risk.
In addition, many vehicle models, such as light buses and pickup trucks, are also equipped with EHPS.
