The invention relates to an automobile auxiliary system using a self-cooling electric machine, and the system comprises the self-cooling electric machine which is used for an electric automobile and comprises a centrifugal switch, a stator, a rotor, a cooling fan, a bearing, a junction box, a transmission shaft, a power supply wire and a protection housing; the content identification mechanism is used for performing judgment processing on the depth-of-field change trend of the same vehicle object in each frame of received tail end operation picture, and sending a speed reduction detection signal when the depth-of-field change trend of a certain vehicle object of which the occupied pixel always exceeds the limit in each frame of tail end operation picture is an acceleration decreasing trend; and the acceleration detection module is also used for sending an acceleration detection signal when the depth-of-field change trend is an acceleration increasing trend. By means of the method and device, a driver can be replaced to judge whether a scene that a closer vehicle is rapidly driven away or rapidly braked exists in front of the electric vehicle or not, the two different scenes are distinguished, meanwhile, a coping scheme of the vehicle is given, and therefore the possibility of occurrence of vehicle accidents is reduced.

    本发明涉及一种使用自冷电动机械的汽车辅助系统,包括:自冷电动机械,用于电动汽车,包括离心开关、定子、转子、冷却风扇、轴承、接线盒、传动轴、电源接线和保护外壳;内容辨认机构,用于在接收到的各帧末端操作画面中执行对同一车辆对象的景深变化趋势的判断处理,并在各帧末端操作画面中存在某一占据像素始终超限的车辆对象的景深变化趋势为加速递减趋势时,发出降速检测信号,还用于在景深变化趋势为加速递增趋势时,发出提速检测信号。通过本发明,能够替换驾驶员执行电动汽车前方是否存在较近车辆快速驶离或者快速刹车的场景的判断,并对上述两种不同场景进行区别,同时给出本车的应对方案,从而降低车辆事故发生的可能性。
