Abstract

The embodiment of the present disclosure discloses an idle speed control method and device of an extended-range vehicle, which relates to vehicle control technology, and can solve the problem that the addition of anti-shake control to the idle speed control process of the existing range-extended vehicle makes the idling vibration phenomenon more serious. The method of the embodiment of the present disclosure mainly includes: controlling the vehicle engine system to output positive torque, and at the same time controlling the vehicle generator system to output negative torque so as to recover energy; The number of revolutions adjusts the output of the negative torque of the generator for idle speed control. The embodiments of the present disclosure are mainly applicable to the idle speed control process of the extended-range vehicle.

Description

technical field [0001] Embodiments of the present disclosure relate to vehicle control technology, in particular to an idle control method and device for an extended-range vehicle. Background technique [0002] With people's consideration of environmental protection and economy, traditional gasoline and diesel vehicles have been difficult to meet people's more economical and more environmentally friendly needs. Therefore, extended-range vehicles have gradually become popular. The idle speed control problem that plagues traditional vehicles has gradually attracted the attention of experts for range-extended vehicles. [0003] Usually, in the idle speed control process of the range-extended vehicle, the method adopted by most range-extended electric vehicles is to control the output shaft of the engine and the input shaft of the generator while maintaining the torque at 0 N·m in the idling condition. Torque output status. However, in practical applications, since the generat...
