The invention discloses a target road spectrum obtaining method and system and a computer readable storage medium, and the method comprises the steps: obtaining a wheel center force of a wheel of a vehicle under selected excitation as a first wheel center force according to the selected excitation acting on the wheel of the vehicle; obtaining a wheel displacement transmissibility from the road surface to the wheel center according to the first wheel center force and the selected excitation spectrum; acquiring the wheel center force of the vehicle running on the target road as second wheel center force; and obtaining a target road spectrum according to the wheel displacement transmissibility and the second wheel center force. According to the method for obtaining the road spectrum of the target road, the first wheel center force of the vehicle under the selected excitation is obtained, the wheel displacement transmissibility from the road surface to the wheel center is obtained according to the first wheel center force and the selected excitation, and the second wheel center force when the vehicle runs on the target road is obtained; the target road spectrum is obtained according to the wheel displacement transmissibility and the second wheel center force. The obtaining method is low in cost, short in time and easy and convenient to operate.
