| Abstract: | The necessity of the electric vehicle fitted with the vacuum assist brake system is analyzed.The performance of the vacuum assist brake system is computed,and the computation flow of the minimum vacuum of the electric vacuum pump is designed.Taking a light-duty bus that is refitted into a hybrid electric vehicle for example,the whole computation parameters of the brake system are given.The computation results show that if the brake force produced by the brake system will meet the design requirement,the electric vacuum pump must offer 37.5kPa vacuum at least.The complete vehicle tests show that the parameters of the electric vacuum pump are appropriate. |
