The invention relates to an electronically controlled hydraulic power steering system and a multi-objective optimization method based on the system. The electronically controlled hydraulic power steering system comprises a steering mechanical unit, a steering valve opening degree adjusting unit, an oil pump adjusting unit and an electronic control unit (ECU). The problems that in a traditional electronically controlled hydraulic power steering system, steering assistance power can be changed only by changing the rotating speed of an oil pump drive motor, and the opening degree of a steering valve can be linearly adjusted only according to the corner of a steering wheel are solved. Meanwhile, multi-objective optimization is carried out on the electronically controlled hydraulic power steering system, steering road feelings, steering sensitivity and energy consumption are taken as objectives, based on a modified Memetic intelligence algorithm, optimization design is carried out on mechanical parameters and hydraulic system parameters of the electronically controlled hydraulic power steering system, and therefore the system has the good steering road feelings and steering sensitivity with smaller energy consumption.
