EHPS adopts PMSM & ECU Powerpack to drive the hydraulic recirculating ball.
EHPS can set the power-assisted curve which changes with the vehicle speed, to solve the problem that HPS cannot balance both the lightness at low speed and steering stability in high speed.
Besides, the problem of poor fuel economy is also solved by separating the steering pump from the engine.
Provide multiple power-assisted modes such as Active-return, high-speed damping, temperature protection, end protection, as well as control functions such as off-hand monitoring and body stability.
Meet the SAE Levels of driving automation L2.5 and can realize intelligent steering functions such as LKA, TJA and APA
Meet the requirement of Automotive Safety Integrity Level 26262
