The invention discloses an automobile driving mode selection method and system. The method comprises the steps of detecting whether a motor state has a fault; if so, alarming and braking; if not, the hydrogen storage amount in the hydrogen cylinder is detected; when the hydrogen storage amount in the hydrogen bottle is not higher than the hydrogen storage amount threshold value, detecting the residual electric quantity of the power battery; when the hydrogen storage amount in the hydrogen cylinder is higher than the hydrogen storage amount threshold value, the wheel slip rate is detected; when the residual electric quantity of the power battery is higher than an electric quantity threshold value, the wheel slip rate is detected; when the residual electric quantity of the power battery is not higher than the electric quantity threshold value, the four-wheel drive mode is forbidden to be used; and selecting a driving mode according to the detected wheel slip rate. The residual energy of the vehicle-mounted power source and the actual road condition are considered at the same time to adjust the driving form, and the driving efficiency is improved.

    本发明公开了一种汽车驱动方式选择方法及系统。该方法包括:检测电机状态是否存在故障;若是则进行报警,并制动;若否,则对氢瓶中氢气储量进行检测;当氢瓶中氢气储量不高于氢气储量阈值时,对动力电池剩余电量进行检测;当氢瓶中氢气储量高于氢气储量阈值时,对车轮滑移率进行检测;当动力电池剩余电量高于电量阈值时,对车轮滑移率进行检测;当动力电池剩余电量不高于电量阈值时,则禁止使用四驱模式;根据检测到的车轮滑移率选择驱动方式。本发明同时考虑车载动力源剩余能量与实际路面情况来进行驱动形式的调整,提高了驱动效率。
