At present, the electric vehicle manufacturer does not consider the situations that minors drive the electric vehicle and do not drive according to the specifications when producing products. When the driver rides the electric bicycle, a call or a short message is sent to reply suddenly, many drivers can reply while riding the electric bicycle, and the electric bicycle is in a state of riding with one hand and being not concentrated in attention, so that the driver cannot take effective safety measures in time to cause safety accidents once the road conditions change suddenly.

Secondly, some parents are busy in the career and cannot nurse the immature children, so that the children can ride the electric vehicle on the road privately, and the safety of the children and others is threatened greatly because the immature children cannot reach the driving condition and cannot judge the road condition timely and take corresponding measures.

The handle of the existing electric vehicle is only composed of a plastic insulator, the structure is simple, no induction device is arranged, the interior of the handle is in a hollow state, and the existing circuit induction device technology and sensor technology are mature, so that the space is greatly utilized. From the above points, the invention efficiently identifies the contact area of the handle and whether the left handle and the right handle are simultaneously contacted through the combination of the handle and the sensing device, judges whether an adult or a child drives and whether the child simultaneously holds the handle by both hands, and contributes to eliminating potential safety hazards caused by improper personal operation. In addition, the invention has low price, mature sensing technology and circuit control technology, small occupied space and no influence on the health of the driver.
