采用"状态转移"控制分析方法,将整车的控制分为相对独立的控制状态,详细分析了在不同工况下的控制状态之间的相互跳转.以双轴并联单离合器结构的HEV进行了多能源动力总成的设计为例,对某一混合动力车辆的起步、行驶和制动等工况的控制进行了分析.采用混合动力车辆专用分析软件Psat进行了控制仿真研究.结果表明,该方法能有效地解决混合动力车辆多能源管理系统设计困难的问题.

This article provides some improvement on the software of an inertial north-seeker test system.By vritue of visual instrument technique,software based on Lab VIEW IDE has been designed to fulfill the desired function of north- seeker test system.

As the battery charging in the running HEV makes it necessary to improve the engine control,this article introduces a throttle electronicvalvecontrol scheme.Based on the electronicenginecontrol unit,the scheme adds a throttle control device to prevent the performance deterioration during battery charging process when the HEV is running.A test has been carried out on the Changan Lingyang Model 7130 car equipped with the throttle electronicvalvecontrol system.The test has validated the operation condition and the control method of the electronicthrottle control and indicated that the scheme is practical. 
