Device and method for evaluating driving road conditions

According to a device and method for evaluating the driving road condition, an accelerator controller is adopted to control the accelerator opening degree, and a vibration sensor is used for collecting vehicle vibration signals; under a certain accelerator opening degree, vehicle vibration signals of different road sections belonging to a certain grade of road conditions are collected, a vibrationsignal characteristic value of each road section is extracted based on the collected vehicle vibration signals, the vibration signals of multiple road sections are collected and summarized, and a vibration signal characteristic value set of the corresponding grade of road conditions is formed; and finally, the current driving road condition level of the vehicle is judged according to the set to which the current vehicle vibration signal characteristic value belongs. The method can better adapt to unfamiliar road sections, so that the vehicle has better environmental adaptability, the vibration signals in the vehicle
