[0019] The present invention will be further described below in conjunction with the drawings.
[0020] in figure 1 Among them, the vehicle ABS (anti-lock braking system) has four wheel speed sensors, namely the first wheel speed sensor 1, the second wheel speed sensor 2, the third wheel speed sensor 3, and the fourth wheel speed sensor 4; ECU (Electronic control unit) is the control unit of ABS, GPS is the global positioning system module, and VNCU is the car navigation control unit, which is composed of power input, data output, and storage control module. The first wheel speed sensor 1, the second wheel speed sensor 2, the third wheel speed sensor 3, and the fourth wheel speed sensor 4 are respectively connected to the ECU, the ECU is connected to the VNCU, and the GPS is connected to the VNCU. The ECU collects the time sequence of the vehicle wheel speed through the first wheel speed sensor 1, the second wheel speed sensor 2, the third wheel speed sensor 3, and the fourth whe...
