Furthermore, the flexible film pressure sensor also comprises a display, wherein the display is connected with the circuit control system and is used for displaying the numerical value sensed by the flexible film pressure sensor.
Further, in step 2, a stress area threshold value is preset in the circuit control system, and when the left and right handles sense that the stress area of the human hand is larger than the stress area threshold value, the human is judged to be an adult; and when the left handle and the right handle sense that the force area of the hand is smaller than the force area threshold value, judging as the child.
Further, the threshold value of the force-bearing area is 80% of the contact area of the handle.
Further, in step 4, a pressure threshold is preset in the circuit control system, and when the left and right handles sense that the pressure generated when the hands hold the handles is greater than the pressure threshold, the hands are determined to be the grips of both hands; and when any one handle senses that the pressure generated by holding the handle is smaller than the pressure threshold value, judging as the non-double-hand grip.
Compared with the prior art, the invention has the advantages that:
1. whether the contact area through flexible piezoresistive sensor judges that the adult or child is driving, with this data transmission to circuit induction system decision whether start the electric motor car, be convenient for control child ride the electric motor car privately to the potential safety hazard takes place.
2. Whether the flexible piezoresistive sensors of the left handle and the right handle are simultaneously contacted to judge whether the electric vehicle is ridden by one hand or not, the data is transmitted to the circuit sensing device to determine whether the electric vehicle is started or not, and bad behaviors of a driver can be standardized.
