Abstract

The invention discloses an electric brake booster for an automobile. The electric brake booster comprises a shell and further comprises a jacking rod assembly and a pushing rod assembly which are mounted in the shell; the pushing rod assembly comprises a pushing rod, one end of the pushing rod is connected with a pedal, and the other end of the pushing rod and the jacking rod assembly have a decoupling gap; and the jacking rod assembly comprises a jacking rod, one end of the jacking rod is connected with a driving mechanism, and the other end of the jacking rod is connected with a main cylinder piston. When a driver steps on the pedal, the driving mechanism receives a signal to drive the jacking rod to push the main cylinder piston to achieve braking, meanwhile the pushing rod makes linearmotion under pushing of the pedal, and the pushing rod does not jack the jacking rod assembly because the pushing rod and the jacking rod assembly have the decoupling gap; and when an electric control system loses efficacy, the driving mechanism is not started, after the pedal drives the pushing rod to eliminate the decoupling gap, the pushing rod jacks the jacking rod assembly, the main cylinderpiston is pushed by the force generated by stepping of the driver on the pedal, and thus braking under the electric control failure situation is achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electric brake booster for automobiles and a control method thereof. Background technique [0002] With the improvement of the country's consumption level, cars have accelerated into ordinary families, and more and more consumers have put forward higher and higher requirements for the comfort, safety and economy of cars. With the gradual improvement of automatic parking and braking driving technology, more and more consumers will choose this kind of comfort configuration. These two functions must require that the car can realize automatic braking. Automatic emergency braking system has become a major The key research and development project of the car factory. [0003] Most of the traditional car braking systems use vacuum booster. The vacuum booster uses vacuum (negative pressure) to increase the force exerted by the driver on the pedal. As long as you step on the pedal ...
