The mandatory standard GB 7258 plus 2017 Motor vehicle operation safety technical conditions clearly provides that a pure electric vehicle and a plug-in hybrid electric vehicle can send out proper prompting sound to personnel outside the vehicle when the vehicle starts and the speed is lower than 20 km/h. In addition, the national standardization administration committee for the problem issues a standard GB/T37153 'electric vehicle low-speed prompting sound' in 2018 in 12 months, and a uniform regulation is specially made on the electric vehicle low-speed driving prompting sound.
On the other hand, the U.S. road traffic safety administration has issued reports that tire pressure is lower than the standard value by 25%, and the tire burst probability is increased by 3 times; the tire burst probability is increased by 1 time when the standard value is 25 percent; the data of the national ministry of public security shows that 70 percent of traffic accidents of domestic expressways are caused by tire burst, the tire burst is carried out at the speed of over 160 kilometers per hour, and the death rate is 100 percent; the united states law requires that all passenger vehicles and light trucks sold in the united states from 8 months in 2007 must be equipped with a tire pressure monitoring system, and all vehicles in China are forced to be equipped with a tire pressure monitoring system from 1 month and 1 day in 2020 as specified in the provisions of performance requirements and test methods for passenger vehicle tire pressure monitoring systems in the provisions of the national provisions. The existing vehicle tire pressure information prompting mode is only displayed on an instrument, and a vehicle owner cannot observe the abnormal prompting of the tire pressure on the instrument in time when driving on a highway, so that traffic accidents can be caused.
Therefore, in order to fully guarantee the road driving safety of the electric automobile, a novel safety driving prompt sound system needs to be developed.
