摘　　要：某纯电动SUV车型在整车动力性开发前期,利用Cruise仿真发现百公里加速不满足目标要求,针对此问题进行分析优化和试验验证。通过增大轮胎抓地力提升峰值扭矩,和通过加大IGBT电流提升恒功率段扭矩,有效地提升了整车动力性能,实现了百公里加速的达标,体现了车型的竞争力。A pure electric SUV models at the early stage of the vehicle power performance development, using Cruise simulation found 0 ~100 km/h acceleration did not meet the requirements of the target, for the problem to optimize and test validation. By increasing the tire grip peak torque, and increasing the IGBT current to improve the constant power period of torque, effectively improved the vehicle dynamic performance, to achieve the target, embodied the competitiveness of the car.

关 键 词：纯电动SUV 整车动力性 百公里加速 峰值扭矩 恒功率段扭矩
