Abstract: A control system for a hybrid electric vehicle comprises a transmission system configured to drive wheels, an engine power subsystem connected to the transmission system, a motor power subsystem connected to the transmission system and a control module. When vehicle's electrical power is on, the control module is configured to control operating mode of the hybrid electric vehicle through the engine power subsystem and the motor power subsystem. The operating mode comprises HEV-eco mode and HEV-s mode. When the hybrid electric vehicle operates in HEV-eco and the hybrid electric vehicle operates at low power or when the hybrid electric vehicle operates in HEV-s mode and when the vehicle speed is zero, the control module enables the hybrid electric vehicle to operate by idle start-stop strategy.
