摘要

集成启动交流发电机(ISA)需要满足非常广泛的扭矩和速度范围,在电机和发电机模式和不同的功能,如发动机启动,交流发电机,再生制动和扭矩提升。此外,这些功能都依赖于驱动周期,这意味着确定最佳ISA转矩-速度特性是一个具有挑战性的问题。本文采用蒙特卡罗模拟方法,利用随机驱动周期,找到了ISA的转矩-速度平面上最频繁操作的区域。这已被用于确定最佳转矩-速度特性,以通知ISA设计规范。反过来,与传统的基于驾驶循环的设计相比,这提供了更强大的不同驾驶模式覆盖范围

Integrated starter alternator sizing for micro / mild hybrid vehicle using Monte Carlo simulation
The Integrated Starter Alternator (ISA) needs to cater for a very wide range of torque and speed, in both motor and generator modes and in different functionalities, such as engine starting, alternator, regenerative braking and torque boost. Furthermore, each of these functionalities, being dependent on the drive cycle, means that determining the optimal ISA torque-speed characteristics is a challenging problem. In this paper, a Monte-Carlo simulation has been reported to find the most frequently operated regions in the torque-speed plane of an ISA, using stochastic drive cycles. This has been used to determine the optimal torque-speed characteristic to inform the ISA design specification. In turn, this gives a more robust coverage of different driving patterns compared to a conventional driving cycle-based design
