Turbocharged vehicles, due to their intake turbocharging principle, have low vacuum at the intake manifold and cannot provide sufficient vacuum sources; On hybrid vehicles, due to the inability of the engine to operate full-time, sufficient vacuum cannot be guaranteed; After the engine assembly of a pure electric vehicle or fuel cell vehicle is removed, the braking system directly loses its vacuum power source. The above (except for traditional gasoline engine cars) braking force generated solely by human power cannot meet the needs of driving braking, and the core problem is to generate a vacuum source with sufficient pressure. The design and use of electronic vacuum pumps better meet this requirement.
