The invention provides an electronic hydraulic regulator and an automotive brake energy recovery system using the electronic hydraulic regulator; the electronic hydraulic regulator works on the basis of the relevant characteristics of the viscosity of an electrorheological fluid material and the electric field and controls the viscosity of the electrorheological fluid material by using voltage; when the viscosity of the electrorheological fluid material is changed, the flow of a brake fluid flowing to a proportional valve is changed an the different brake forces are generated. The electronic hydraulic regulator is connected in series with a hydraulic pipeline of an automotive brake system to form the automotive brake energy recovery system; the fine regulation of the brake force is controlled by changing the viscosity of the electrorheological fluid material in the electronic hydraulic regulator by using control voltage, and assists with the distribution requirements of electric brake and hydraulic brake power distributors to the brake forces, so that the recovery of the brake kinetic energy of an electric vehicle is realized and the recovery problem of the brake energy in the electric vehicle is solved; the driving mileage of the electric vehicle is improved and the performance of the electric vehicle is improved obviously.
