Novel energy-saving type electronic control power-assisted steering system

The invention belongs to the field of power-assisted steering equipment, and particularly relates to a novel energy-saving type electronic control power-assisted steering system. The novel energy-saving type electronic control power-assisted steering system comprises a steering machine, and is characterized by further comprising an electric hydraulic pump connected with the steering machine, hydraulic pipelines, an oil tank communicated with the electric hydraulic pump, an electronic control unit respectively connected with the steering machine and the electric hydraulic pump, and a hydraulic accumulator arranged on the hydraulic pipelines. The novel energy-saving type electronic control power-assisted steering system is big in assisting power, high in energy density, and energy-saving, and feeling of the assisting power is changeable with the speed of a vehicle.
