Intelligent gear shifting control method and system for conventional vehicle

The invention discloses an intelligent gear shifting control method for a conventional vehicle. The method comprises the steps that the vehicle speed interval and the current vehicle speed of the whole vehicle are obtained; according to the whole vehicle speed interval, the gear of the gearbox is judged according to the ratio of the engine rotating speed to the gearbox rear shaft rotating speed; and according to the gear of the gearbox and the current vehicle speed, intelligent gear shifting reminding is conducted through an instrument. The method is realized based on a CAN bus instrument, the problem of long-time neutral-gear sliding of a conventional vehicle is solved, the vehicle runs more safely, and the braking function of an engine is effectively utilized. 本发明公开了一种常规车智能换挡控制方法，包括：获取整车车速区间和当前车速；根据整车车速区间，利用发动机转速与变速箱后轴转速的比值判断变速箱档位；根据变速箱档位和当前车速，通过仪表进行智能换挡提醒。本发明基于CAN总线仪表实现，解决了常规车长时间空挡滑行问题，车辆行驶更加安全，有效的利用发动机制动功能。
