The invention relates to the technical field of new energy automobiles, in particular to a low-speed prompting method and device for a vehicle, and the method comprises the steps: collecting the actual vehicle speed of the vehicle, judging whether the actual vehicle speed is in a preset low-speed driving interval, and if the actual vehicle speed is in the preset low-speed driving interval, prompting the vehicle to run. If yes, harmonic parameters injected into the driving motor are matched according to the actual vehicle speed, harmonic injection is conducted on the driving motor based on the harmonic parameters while the driving motor is controlled to provide driving force for the vehicle, and a low-speed prompt tone for conducting low-speed prompt on a driver is generated. According to the embodiment of the invention, the intensity of the noise generated by the driving motor can be reversely increased through harmonic injection based on the current noise generated during driving of the electric vehicle, and real-time adjustment is carried out according to the vehicle speed, so that the vehicle driving prompt tone requirement is met by utilizing the characteristics of the electric vehicle, pedestrians are reminded to avoid, the intelligence of vehicle safety protection is improved, and the safety of the vehicle is improved. And the cost of the whole vehicle is reduced.

    本申请涉及新能源汽车技术领域,特别涉及一种车辆的低速提示方法及装置,其中,方法包括:采集车辆的实际车速,并判断实际车速是否处于预设低速行驶区间,如果实际车速处于预设低速行驶区间,则根据实际车速匹配注入驱动电机的谐波参数,在控制驱动电机为车辆提供驱动力的同时,基于谐波参数对驱动电机进行谐波注入,生成对驾驶员进行低速提示的低速提示音。本申请实施例可以基于电动汽车驱动时产生的电流噪音,通过谐波注入反向增大驱动电机产生的噪声强度,并根据车速进行实时调整,以利用电动汽车特性实现车辆行驶的提示音要求,从而提醒行人避让,提升了车辆安全防护的智能性,降低了整车成本。
