The invention mainly aims to provide a sliding saddle control system and a control method, and aims to solve the problems that the existing sliding saddle scheme is low in automation and intelligent degree and cannot adjust sliding distance according to use conditions. Fig. 1 to 3 are schematic structural views of an embodiment of a sliding saddle control system according to the present invention.

Referring to fig. 1, the sliding saddle control system 1000 includes a sliding saddle assembly 100, a resistance sensor 200, a load sensor 300 and a control device, where the sliding saddle assembly 100 includes a fixing frame 1, a sliding seat 2 and a driving device 3, the fixing frame 1 is fixedly installed on a vehicle body, the sliding seat 2 is slidably disposed on the fixing frame 1 along an extending direction of the vehicle body, the driving device 3 is in driving connection with the sliding seat 2, so as to drive the sliding seat 2 to slide, the resistance sensor 200 is used for detecting a running resistance of the vehicle, the load sensor 300 is used for detecting a front axle load of the vehicle, and the control device is electrically connected with the driving device 3, the resistance sensor 200 and the load sensor 300, respectively, and is used for controlling the sliding seat 2 to slide according to the running resistance and the front axle load of the vehicle.

In the technical scheme provided by the invention, the sliding saddle assembly 100 is arranged, and a control device electrically connected with the sliding saddle assembly 100 is arranged, so that the sliding distance of the sliding saddle is automatically controlled. Further, by setting the resistance sensor 200 and the load sensor 300, vehicle running data such as running resistance of the vehicle, front axle load and the like are monitored in real time, so that the control system can control the running state of the vehicle in real time, and the system can find out the sliding distance under the optimal working condition conveniently by analyzing the running state of the vehicle from different angles, thereby solving the problem that the sliding distance cannot be adjusted according to the using working condition, and realizing the automation and the intellectualization of the sliding saddle system.
