[0027] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0028] like Figure 1 As shown, this embodiment provides a vehicle parking light warning system, which includes a main controller, a tail ultrasonic ranging module, a tail light assembly, an in-vehicle warning light 5, a button module 6 and a voice prompt module 7. Figure 3 As shown, the in-vehicle warning light 5, the button module 6 and the voice prompt module 7 are all integrated and installed on the steering wheel.

[0029] like Figure 1 As shown, the rear ultrasonic ranging module of this embodiment is connected to the main controller. When the vehicle decelerates or stops after stepping on the brake, it measures the distance between the rear vehicle or moving object and the vehicle. When the distance between the rear vehicle or moving object and the vehicle is 10 meters, 5 meters, and 3 meters, the signal is sent to the main controller respectively. Figure 4 As shown, the rear ultrasonic ranging module of this embodiment is composed of a transmitting antenna T40, an RS232 communication chip U1, a single-chip microcomputer U2, an operational amplifier chip U3 and a receiving antenna R40. After the transmitting antenna T40 emits ultrasonic waves, the echo is received by the receiving antenna R40 after contacting the rear vehicle or moving object. The signal is then processed by the operational amplifier and enters the single-chip microcomputer U2 for operation and processing to obtain the distance value.
