The invention provides an intelligent gear shifting reminding system and method for a vehicle. The intelligent gear shifting reminding method comprises the steps that an ECU collects the rotating speed and torque of an engine to obtain rotating speed data and torque data respectively; a gradient sensor acquires road surface gradient to obtain gradient data; a speed sensor acquires the speed of thevehicle to obtain speed data; a vehicle weight detection system collects a whole vehicle load to obtain vehicle weight data; a VCU determines that the vehicle is in a driving state according to the vehicle speed data and the rotating speed data, calculates a current gear speed ratio of the vehicle according to the vehicle speed data and the rotating speed data, and searches a corresponding current gear of the vehicle from a pre-stored database according to the current gear speed ratio; according to the current gear speed ratio, the torque data, the vehicle weight data and the gradient data ofthe vehicle, oil consumption and vehicle driving force under the current application working condition are calculated; and whether the oil consumption is in a pre-stored oil consumption curve or notand whether the vehicle driving force is in a pre-stored dynamic curve or not is judged, if not, gear shifting reminding on the vehicle is performed, and gear shifting reminding information displayedby an instrument is generated.

    本发明提供了车辆的智能换档提醒系统和方法,包括:ECU采集发动机的转速和扭矩分别得到转速数据和扭矩数据;坡度传感器采集路面坡度得到坡度数据;车速传感器采集车辆的速度得到车速数据;车重检测系统采集整车载荷得到车重数据;VCU根据车速数据和转速数据确定车辆处于行驶状态,根据车速数据和转速数据计算车辆当前档位速比,根据当前档位速比从预存数据库中查找对应的车辆当前档位;根据车辆当前档位速比、扭矩数据、车重数据和坡度数据,计算当前应用工况下的油耗和车辆驱动力;判断油耗是否在预存的油耗曲线内,以及车辆驱动力是否在预存的动力性曲线内,如果不在,则对车辆进行换档提醒,生成仪表显示的换档提醒信息。
