混合动力电动车辆控制器和方法
Abstract:
本发明涉及一种用于具有动力传动系的并联式混合动力电动车辆的控制器(140)，该动力传动系包括发动机(121)，由能量存储装置(150)供电的电动推进装置(123B；123C)以及能够操作成由发动机(121)驱动以对能量存储装置充电的发电机装置(123B；123C)。控制器(140)能够操作成：接收指示在给定时刻操作车辆的一个或更多个操作模式的一个或更多个信号，一个或更多个操作模式选自多个操作模式；接收指示所要求的动力传动系驱动扭矩的信号；以及根据指示所要求的动力传动系驱动扭矩的信号而使得发动机(121)和电动推进装置(123B；123C)向一个或更多个车轮(111；112；113；114)传递驱动扭矩以驱动车辆，控制器(140)能够操作成使得动力传动系在并联动力传动系模式下操作，在该模式下，控制器能够操作成除了发动机(121)之外还使得电动推进装置(123B；123C)向一个或更多个车轮施加驱动扭矩，由电动推进装置传递的扭矩的量是由控制器(140)至少部分地根据指示所要求的动力传动系驱动扭矩的信号以及指示操作车辆的一个或更多个操作模式的一个或更多个信号来确定的。本发明还涉及一种相应的方法。
Abstract(English):

A controller is provided for a parallel hybrid electric vehicle. The vehicle powertrain includes an engine, an electric propulsion motor powered by an energy storage device, and an electric generator driven by the engine to recharge the energy storage device. The controller receives one or more signals indicative of one or more operating modes in which the vehicle is to be operated; receives a signal indicative of demanded powertrain drive torque; and causes the engine and electric propulsion motor to deliver drive torque to one or more wheels to drive the vehicle. The controller causes the powertrain to operate in a parallel powertrain mode, where the amount of torque delivered by the electric propulsion motor is determined by the controller in dependence on the signal indicative of demanded powertrain drive torque and the one or more signals indicative of the one or more operating modes.
