Embodiment Construction

[0017] The method for controlling the start-up of a hybrid electric vehicle engine provided by the invention, the invention includes:

[0018] Hybrid power controller, the hybrid power controller is used for the control of engine idle stop and quick start;

[0019] When executing the engine automatic start-stop function, the hybrid power controller needs to judge the vehicle condition and the driver's operation behavior, and send an execution signal;

[0020] The engine control module is used for the control of the vehicle engine;

[0021] The hybrid power controller and the engine control module realize the function control of the start and stop functions of the engine through the vehicle CAN network communication.

[0022] The vehicle conditions that the hybrid power controller needs to judge include: battery function status, engine warm-up status, hybrid power motor starting function status, air conditioning and defrosting electrical system status, power steering and power...

Abstract

The present invention is automatic engine staring control method. The present invention includes one mixed power controller for controlling the idle stopping and fast starting of engine and one engine controlling module for controlling the engine. Under certain automobile condition and driver's operation, the mixed power controller judges and sends out execution signal and communicates mutually with the engine controlling module through the automobile CAN network for automatic on-off of the engine. The present invention can realize the fast smooth starting of the engine after idle starting and has low noise and low exhaust.

Description

technical field [0001] The invention relates to the control of a hybrid electric vehicle. technical background [0002] Energy shortage and environmental pollution are two major challenges encountered by the development of the automobile industry at present. Relevant data show that 82% of CO and NO in the urban atmosphere x 48% of HC, 58% of HC, and 8% of particulates are all from the exhaust gas emitted by automobiles; according to the prediction of the National Environmental Protection Center, automobile exhaust emissions will account for 64% of air pollution sources in 2010. Since 2000, my country has begun to fully implement new emission regulations. For example, vehicles sold on the market in Beijing at the end of 2005 must meet Euro III emission standards. Over time, national emissions regulations will become more stringent. On the other hand, my country's oil resources are relatively small. Since 1994, my country has been an oil importing country, so energy saving ...
