摘要： An electrically assisted supercharging control method for an engine is disclosed, including: disposing a one-way valve (4) and an intake branch (5) connected in parallel to the one-way valve (4) on an intake channel (3) between an exhaust gas compressor (1) and an intake manifold (2), disposing an auxiliary air compressor (6) on the intake branch (5), and controlling, according to actual engine parameters, the auxiliary air compressor (6) to operate at a smoothly changing rotation speed. An electrically assisted supercharging control system for an engine is further disclosed. Compressed air can be prevented from driving an impeller of the auxiliary air compressor to rotate, design and use costs of the auxiliary air compressor are reduced, and operation performance of the engine is ensured.
