Problems solved by technology

During the running of the pure electric vehicle, for example, if a fault occurs between the vacuum pump and the vacuum air storage tank, the vacuum degree in the vacuum air storage tank will be insufficient, resulting in the failure of the brake control system to work normally and increasing the number of rides. Danger to persons, including driver and passengers

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] figure 1 Shown is the vacuum booster system 50 of the electric vehicle of the present invention, which can be used for the auxiliary braking device 20 to brake the electric vehicle. The vacuum booster system 50 includes a booster 3 connected to the braking device 20 , and an air storage element 2 connected to the booster 3 . The gas storage 2 can also be called a vacuum gas storage. The air storage device 2 is preferably a vacuum air storage tank or a vacuum air storage tank. A sensor 7 is arranged on the gas reservoir 2 . Since the sensor 7 is used to detect the vacuum degree in the gas storage element 2, the sensor 7 is preferably a vacuum degree sensor.

[0020] In this embodiment, the vacuum booster system 50 also includes a vacuum pump 1 . The vacuum pump 1 and the gas storage device 2 communicate with each other, thereby facilitating the adjustment of the ...

Abstract

The invention provides a vacuum boosting system and method of an electric automobile. The vacuum boosting system comprises a booster connected onto a brake device, a gas storage part connected with the booster, a sensor arranged on the gas storage part and used for detecting the vacuum degree, a vacuum pump connected to the gas storage part and used for adjusting the vacuum degree in the gas storage part and a driving motor capable of driving the electric automobile. The driving motor can enable the electric automobile to slow down or stop through setting when the vacuum degree detected by sensor is smaller than an alarm value. The vacuum boosting system of the electric automobile can assist the brake device to performing braking of the electric automobile and can effectively and actively reduce the running speed or enable the electric automobile to stop when breaking down or being in the dangerous situation, and therefore the safety of passengers is ensured.

Description

technical field [0001] The invention relates to a vacuum booster system and a method thereof for an electric vehicle, which can be used for an auxiliary braking device to brake the electric vehicle. Background technique [0002] As we all know, electric vehicles generally use a vacuum booster system to assist the braking device to brake the electric vehicle, so that the driver's pedal force for operating the brake pedal can be greatly reduced, thereby improving the driver's comfort. [0003] Chinese patent CN102673551A discloses a pure electric vehicle electric vacuum booster brake control system, which uses a pressure sensor to detect whether the vacuum degree in the vacuum air storage tank is sufficient. When the vacuum degree in the vacuum air storage tank is insufficient, the vacuum booster brake controller will turn on the vacuum pump to replenish the vacuum degree in the vacuum air storage tank, thereby ensuring the safety of the brake control system. During the runni...
