The sliding saddle control system of claim 2, wherein the sliding saddle assembly further comprises a sliding fit structure comprising a rail and a sliding portion that are mutually matched, the rail being fixedly mounted to the mount along a length of the vehicle body, the sliding portion being provided to the sliding seat;
One side of the sliding seat is provided with a mounting groove;
The gear is arranged in the mounting groove, and one side part of the gear, which is close to the rack, is exposed out of the sliding seat;
The rack is arranged inside the guide rail, so that the sliding part is matched with the guide rail when the rack is meshed with the gear.
7. A sliding saddle control method, based on a sliding saddle control system according to any one of claims 1-6, characterized in that it comprises the following steps:
acquiring an initial sliding distance input by a user and controlling the sliding seat to slide;
monitoring an operating parameter of the vehicle by the resistance sensor and the load sensor;
Determining a state parameter of the vehicle according to the operation parameter;
And when the vehicle state parameters do not meet the preset conditions, generating early warning information, calculating a sliding distance adjustment value according to the vehicle state parameters and the preset parameters, and outputting the sliding distance adjustment value.
8. The sliding saddle control method of claim 7, wherein the sliding saddle assembly further comprises a rack, a gear and a motor, the rack is provided on the fixed frame, the gear is rotatably connected with the sliding seat and is matched with the rack, and the motor is in driving connection with the gear;
The step of obtaining the initial sliding distance input by the user and controlling the sliding of the sliding seat comprises the following steps:
acquiring an initial sliding distance input by a user;
Determining a required rotation parameter of the gear according to the initial sliding distance;
determining a required electric control parameter of the motor according to the required rotation parameter of the gear;
And controlling the motor to rotate according to the electric control parameters required to drive the sliding seat to slide.
9. The sliding saddle control method according to claim 7, wherein the state parameter of the vehicle includes at least one of a load parameter, a steering parameter, and a traction resistance parameter.
10. The sliding saddle control method according to claim 9, wherein the generating early warning information when the vehicle state parameter does not satisfy a preset condition includes:
If the load parameter is larger than a preset load parameter, sending information that the load is too large to reduce the front suspension distance of the vehicle;
if the steering parameter is larger than the preset steering parameter, sending out information that the steering performance is poor and the front suspension distance of the vehicle is reduced;
if the traction resistance parameter is larger than the preset traction resistance parameter, information that the traction resistance is larger and the front suspension distance of the vehicle is increased is sent out.
