The invention provides a vehicle longitudinal acceleration calculation method and device, a server and a storage medium. The method comprises the following steps: vehicle turning state information anda wheel turning angle are calculated according to a steering wheel turning angle and a vehicle speed; vehicle structure parameters are obtained, the vehicle structure parameters comprise a first distance and a second distance, the first distance is the axle distance of the vehicle, the second distance is the distance between a target position of the vehicle and a first intersection point in the longitudinal direction of the vehicle, and the first intersection point is the intersection point of a frame and a rear axle; a first component of centripetal acceleration of the vehicle at the targetposition along the longitudinal direction of the vehicle and a second component of target acceleration of the vehicle at the target position along the longitudinal direction of the vehicle are calculated based on the vehicle turning state information, the wheel turning angle and the vehicle structure parameters, the target acceleration being acceleration along the speed direction of the target position; and the longitudinal acceleration of the vehicle at the target position is calculated by using the first component and the second component. Based on the method, the accuracy of the calculationresult of the longitudinal acceleration of the vehicle under the turning working condition can be improved.
