The invention discloses an automatic upshift and downshift system of a motorcycle engine. The automatic upshift and downshift system comprises a clutch executing mechanism, a gear shifting executing mechanism, a transmission control unit and an engine control unit which are connected with the engine, the engine control unit is used for controlling the ignition angle of an engine and the opening degree of a throttle valve; the transmission control unit is used for monitoring a whole motorcycle signal, generating a control instruction according to the whole motorcycle signal and outputting the control instruction, the clutch executing mechanism, the gear shifting executing mechanism and the engine control unit execute the corresponding control instruction according to the received control instruction, and the whole motorcycle signal comprises the opening degree of an accelerator and the rotating speed/torque of a crankshaft; the transmission control unit further automatically recognizes the road condition state according to the whole vehicle signal, when the road condition state is recognized as the downhill state, a clutch is controlled to be engaged according to the current gear, and when the road condition state is recognized as the uphill state, the upshift frequency of the gear is controlled to be reduced. According to the invention, enough driving force of the whole motorcycle can be ensured, the overall dynamic property is improved, and normal running of the motorcycle can be ensured.

    本发明公开了一种摩托车发动机自动升降挡系统,包括与发动机连接的离合执行机构、换挡执行机构、变速器控制单元和发动机控制单元;发动机控制单元,用于控制发动机点火角和节气门开度;变速器控制单元,用于监测摩托车整车信号并根据整车信号生成控制指令并输出,离合执行机构、换挡执行机构和发动机控制单元根据接收并执行相应的控制指令,整车信号包括油门开度、曲轴转速/扭矩;变速器控制单元还根据整车信号自动识别路况状态,在识别为下坡状态时,根据当前所在挡位控制离合器接合,在识别为上坡状态时,控制挡位升挡频次降低。本发明能够保证有足够的整车驱动力,提高了整体的动力性,能够保证摩托车的正常行驶。
