The invention discloses an electric vehicle tire pressure monitoring method and system. The electric vehicle tire pressure monitoring method comprises the following steps: acquiring actual test working condition data; filling the actual test working condition data by adopting a linear interpolation method to obtain missing working condition data; the test working conditions are in one-to-one correspondence with the first wheel speed parameter range, and the missing working conditions are in one-to-one correspondence with the second wheel speed parameter range to form a working condition-wheel speed parameter range corresponding relation; determining the current working condition of the electric vehicle; determining a current wheel speed parameter range corresponding to the current working condition based on the current working condition and the working condition-wheel speed parameter range corresponding relation; acquiring a current wheel speed parameter of the electric vehicle; and tire pressure abnormal information is determined based on the current wheel speed parameter and the current wheel speed parameter range, and the tire pressure abnormal information comprises tire pressure abnormity and tire pressure non-abnormity. By the adoption of the scheme, the problems that existing tire pressure monitoring is high in cost and poor in safety are solved.
