Factors affecting braking vacuum of plug-in hybrid electric vehicle (PHEV) are elaborated in this paper. The strategies of negative pressure braking boosting are adjusted based on output conditions of hybrid electric vehicle, and operating plan in high altitude is developed according to operating characteristic of electronic vacuum pump, and vehicle experimental research in typical conditions is carried out. The results show that after the strategies are adjusted, the braking vacuum of this PHEV is improved effectively, and can satisfy the braking requirement in high altitude.
