Problems solved by technology
[0002] At present, many automobile manufacturers in my country have manufactured low-noise vehicles, such as pure electric vehicles and hybrid vehicles. Because these vehicles have very low noise at low speeds, pedestrians on the roadside do not feel that there is a vehicle coming. There is a certain threat to the safety of the vehicle, which may cause traffic accidents

The invention relates to pedestrian cautioning safety system and method of a pure electric mode hybrid electric vehicle and a vehicle thereof. The cautioning system is arranged in an electric control system of the hybrid electric vehicle, and comprises a signal collecting unit, a signal control unit and a sound cautioning execution unit. The signal control unit is connected with the signal collecting unit as well as analyzes and processes the vehicle running state signal collected by the signal collecting unit. The signal control unit is connected with the sound cautioning execution unit and controls the sound cautioning execution unit to execute. The cautioning method comprises the following steps of: in the pure electric mode, judging the signal collected logically, if speed and position of an accelerator pedal meet the judging condition, sounding to alarm by outputting corresponding voltage value according to the depth of the pedal. In the hybrid electric vehicle, the cautioning system is adopted without modifying the circuit system of the original vehicle to realize the pedestrian cautioning safety system for pure electric mode hybrid electric vehicle. Sounds of different degrees are generated due to different speeds to attract the attention of pedestrian.
Description
Technical field [0001] The present invention is directed to a pedestrian warning safety system for hybrid electric vehicles, a hybrid electric vehicle and a warning method under pure electric operation of the hybrid electric vehicle. Background technique [0002] At present, many automobile manufacturers in our country have manufactured low-noise vehicles, such as pure electric vehicles and hybrid vehicles. Since these vehicles make very low noise when driving at low speeds, pedestrians on the roadside cannot feel that there is a vehicle approaching, which is harmful to pedestrians. poses a certain threat to safety and may cause traffic accidents. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pedestrian warning safety system method and vehicle for hybrid electric vehicles that can be easily arranged to provide certain safety guarantees for pedestrians. [0004] In order to achieve the above object, the prese...
