The invention discloses a pedestrian warning control method, comprising: obtaining current running state information of a locomotive, wherein the running state information is used for representing the current running state of the locomotive; according to the current running state of the locomotive, obtaining audio signal information corresponding to the current running state of the locomotive; and controlling a loudspeaker in the locomotive to make the sound corresponding to the current running state of the locomotive by applying the audio signal information. According to the invention, the loudspeaker in the locomotive is controlled to make the sound corresponding to the current running state of the locomotive through the obtained current running state of the locomotive, the problem that the locomotive is relatively quiet when running at a low speed and thus pedestrians cannot aware can be effectively improved, and the probability of accidents happened between the locomotive and pedestrians is decreased.
Description
technical field [0001] The present invention relates to the field of automobiles, and more specifically, relates to a pedestrian warning control method, device and system. Background technique [0002] With the development of automobile energy-saving and emission-reduction technologies, new-generation vehicles such as pure electric vehicles and hybrid vehicles are increasingly widely used. An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply and driven by a motor to drive the wheels. A hybrid vehicle refers to a vehicle in which the vehicle drive system is composed of two or more single drive systems that can operate simultaneously. [0003] The inventors have found through research that since pure electric vehicles and hybrid vehicles use motors as power output when driving at low speeds, the noise of the vehicles is very low, which is quieter than traditional vehicles, and it is not easy for pedestrians to identify pure electric vehicles from ...
