The invention discloses a pavement adhesion coefficient measuring device and method based on pavement texture features. The measuring device comprises a GPS, an inertial navigation sensor, an ABS sensor, a first vehicle-mounted camera, a tire vertical load sensor, a second vehicle-mounted camera, a front wheel angle sensor, a third vehicle-mounted camera and a vehicle active safety control system which are controlled by a core control unit. The measuring method comprises the following steps: extracting tire texture information; image information collection of the position of the road where the vehicle is about to run is completed; extracting road surface information of a road surface to be driven by the vehicle; pavement texture feature recognition and pavement adhesion coefficient estimation of a pavement on which the vehicle is about to run are completed; road surface image information collection of the actual driving road surface position of the vehicle is completed; calculating the adhesion coefficient of the actual driving road surface position of the vehicle; and updating and storing the data through the database. The method is high in real-time performance and high in anti-interference capability, and the situation that the road adhesion coefficient is measured by singly utilizing a sensor is avoided.
