Embodiment Construction

[0015] The implementation of the intelligent electric vehicle based on obstacle detection and recognition of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] The principle of ultrasonic distance measurement is to use the known propagation speed of ultrasonic waves in the air to measure the time it takes for the sound waves to encounter obstacles and reflect back after they are emitted, and to calculate the actual distance from the emission point to the obstacle based on the time difference between emission and reception. It can be seen that the principle of ultrasonic ranging is the same as that of radar. Ultrasonic ranging is mainly used for distance measurement of reversing reminders, construction sites, industrial sites, etc. Although the current ranging range can reach 100 meters, the measurement accuracy can only reach the order of centimeters.

[0017] However, in fact, the propagation speed of ultrasonic waves...
