Problems solved by technology
[0002] Electric vehicles do not have the engine roar of conventional vehicles when driving on pure electricity. Road pedestrians cannot judge whether there is a vehicle approaching through the sound, and will not take the initiative to avoid vehicles, thereby increasing the probability of accidents. Warning system, that is, a sounding device is arranged outside the passenger cabin to remind pedestrians on the road, but this method cannot actively identify pedestrians, and in many cases it will generate unnecessary environmental noise, increase urban noise pollution, reduce driving comfort, and is not humane enough

Embodiment 1
[0040] Based on Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a pedestrian warning method for electric vehicles, including:
[0041] Step S1, obtaining pedestrian warning system working mode information, vehicle power mode information, vehicle speed information, gear information, camera information and radar information through the CAN bus;
[0042] Step S2, controlling the pedestrian warning system not to make a sound or to make a warning sound according to the acquired information.
[0043] Specifically, combined with image 3As shown, in this embodiment, the information on the working mode of the pedestrian warning system provides the user with a choice of the working mode of the pedestrian warning system. The working modes of the pedestrian warning system include three types: normally open mode, normally closed mode and intelligent mode. , the warning unit keeps silent; in the normal open mode, the warning unit makes a warning sound...

The invention provides a pedestrian warning system for an electric automobile and a method. The pedestrian warning system comprises a CAN transceiver unit, a control unit and a warning unit, wherein the CAN transceiver unit is used for acquiring work mode information of the pedestrian warning system, automobile powder mode information, automobile speed information, gear information, camera information and radar information through a CAN bus; the control unit is used for sending a control signal to the warning unit according to the information acquired by the CAN transceiver unit so as to control the warning unit to send or not to send a warning sound; and the warning unit can send or not send the warning sound according to the control signal sent by the control unit. In the pedestrian warning system, a user can freely select the work mode of the pedestrian warning system; and in an intelligent mode, the pedestrian warning system can be actively controlled to send or not send the sound through the pedestrian recognition, so that the pedestrian safety can be guaranteed, the unnecessary environmental noise can be reduced, the driving comfort can be increased, and more options are supplied to the user.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an electric vehicle pedestrian warning system and method. Background technique [0002] Electric vehicles do not have the engine roar of conventional vehicles when driving on pure electricity. Road pedestrians cannot judge whether there is a vehicle approaching through the sound, and will not take the initiative to avoid vehicles, thereby increasing the probability of accidents. The warning system, that is, arranges a sounding device outside the passenger cabin to remind pedestrians on the road, but this method cannot actively identify pedestrians, and in many cases it will generate unnecessary environmental noise, increase urban noise pollution, reduce driving comfort, and is not humane enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric vehicle pedestrian warning system and method to redu...
