Empty.
The vacuum boost system 100 of the motor vehicle driven by mixed power according to this utility model embodiment, by increasing electronic vacuum pump 40
Vacuum booster 20 is carried out evacuation, to guarantee that the vacuum of vacuum booster 20, all the time more than safety value, thus can
When enough ensureing motor vehicle driven by mixed power braking, vacuum booster 20 can provide power-assisted for braking all the time, it is achieved quickly and stably
Braking, improves travel safety and reliability.
So, it is effectively utilized the negative pressure that electromotor 10 work produces, reduces energy resource consumption；And electronic vacuum pump 40 with
Inlet manifold 11 in parallel, in such electronic vacuum pump 40 and electromotor 10 during a unit failure, another parts can be fast
Speed provides vacuum source for vacuum booster 20, and traffic safety has been effectively ensured.
Brief description under the different frosting states of vehicle, the work process of vacuum boost system 100.
When motor vehicle driven by mixed power is under pure motor driving state, vacuum sensor 30 detects the vacuum of vacuum booster 20
Vacuum at access port 21.If be detected that vacuum less than safety value, then control electronic vacuum pump 40 and start with to very
Empty booster 20 carries out evacuation, until the vacuum degree that vacuum sensor 30 detects is higher than safety value.
In particular cases, when motor vehicle driven by mixed power is in pure motor driving state, the vacuum of the vacuum booster 20 detected
Degree breaks down when cannot start less than safety value and electronic vacuum pump 40, then force start electromotor 10 increases system with this
Vacuum, guarantee driving safety.
When motor vehicle driven by mixed power is in mixed dynamic transport condition, electromotor 10 is in running order.The inlet manifold of electromotor 10
11 extract the air in vacuum booster 20 out so that vacuum booster 20 keeps certain vacuum by the first vacuum tube 60, this
