Method and device for adjusting position of seat in vehicle

A device for adjusting a position of a seat in a vehicle, wherein front, rear, left, right and central areas of a seat face are respectively provided with a front pressure sensor, a rear pressure sensor, a left pressure sensor, a right pressure sensor and a pressure sensor ring which comprises a plurality of sub-sensors distributed in a circular manner;

• the device comprises:
• a second acquisition module for obtaining pressure values output by the sub-sensors;
• a calculating module for calculating a mean square value and an average value of the pressure values output by the sub-sensors;
• a judging module for judging whether a ratio of the mean square value to the average value is greater than a preset value;
• a first acquisition module for obtaining pressure values output by the front pressure sensor, the rear pressure sensor, the left pressure sensor and the right pressure sensor when a ratio of the mean square value to the average value is greater than a preset value;
• a first adjusting module for adjusting fore-and-aft positions of the seat according to the pressure values output by the front pressure sensor and the rear pressure sensor;
• and
• a second adjusting module for adjusting lateral positions of the seat according to the pressure values output by the left pressure sensor and the right pressure sensor.
