The invention relates to an automotive distributed electronic hydraulic braking system with pressure retaining valves, which belongs to the technical field of automobile braking systems, and comprises a braking operation unit, an electromagnetic valve block, a pedal feeling simulator, a left front wheel braking actuating mechanism, a left front brake, a left front pressure retaining valve, a right front wheel braking actuating mechanism, a right front brake, a right front pressure retaining valve, a left rear wheel braking actuating mechanism, a left rear brake, a left rear pressure retaining valve, a right rear wheel braking actuating mechanism, a right rear brake and a right rear pressure retaining valve. The automotive distributed electronic hydraulic braking system with the pressure retaining valves can avoid that an ESC (electronic stability control) system cannot perform braking interference when part of the wheel braking actuating mechanisms fails, and is beneficial to improvement on ESC interference effects when part of the wheel braking actuating mechanisms fails. Besides, when the wheel braking actuating mechanisms are used for establishing pressure of the brakes, the pressure of the brakes can be retained without continuously electrifying motors of the wheel braking actuating mechanisms, so that energy consumption is reduced.
