Abstract

The embodiment of the invention discloses an idling control method and device for an extended-range automobile, relates to the automobile control technology, and can solve the problem that the idlingwobble phenomenon is more serious due to the fact that anti-wobble control is added in the idling control process of an existing extended-range automobile. The method mainly comprises the steps: controlling a vehicle engine system to carry out positive torque output, and meanwhile controlling a vehicle generator system to carry out negative torque output so as to carry out energy recovery; detecting the rotating speed of a generator of the current vehicle, and adjusting the output of the negative torque of the generator according to the rotating speed of the generator to perform idling control. The idling control method and device in the embodiment of the invention are mainly suitable for the idle control process of the extended-range automobile.

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...
