混合动力车辆自动起动系统及方法
摘要：
本发明涉及混合动力车辆自动起动系统及方法。一种用于发动机的控制系统，包括在第一模式和第二模式下操作的发动机控制模块(ECM)。ECM产生空转速度信号和基于发动机空转速度的变速器负载信号。混合控制模块(HCM)基于空转速度信号和变速器负载信号增大电动机扭矩以增大发动机的当前速度。HCM在处于第一模式时控制当前速度。ECM在处于第二模式时控制当前速度。在发生以下情形中的至少一者时HCM将对当前速度的控制转移给ECM：当前速度匹配空转速度，和发动机的燃烧扭矩输出等于所请求的曲轴输出扭矩。
摘要（英）：

The invention relates to a hybrid vehicle auto start systems and methods. A control system for an engine includes an engine control module (ECM) that operates in a first mode and a second mode. The ECM generates an idle speed signal and a transmission load signal that is based on an idle speed of the engine. The hybrid control module (HCM) increases electric motor torque to increase a current speed of the engine based on the idle speed signal and the transmission load signal. The HCM controls the current speed when in the first mode. The ECM controls the current speed when in the second mode. The HCM transfers control of the current speed to the ECM when at least one of the current speed matches the idle speed and a combustion torque output of the engine is equal to a requested crankshaft output torque.
