Vehicle controller having modification prevention device
A vehicle controller has a modification prevention device, and the vehicle controller includes: a printed circuit board; a security module frame seated on the printed circuit board and having multiple coupling holes; and security modules inserted into the coupling holes and configured to electrically communicate with a circuit of the printed circuit board. In particular, the security modules include non-conductive insertion pins and conductive insertion pins inserted into the coupling holes, and the non-conductive insertion pins and the conductive insertion pins are scattered while being separated from the coupling holes of the security module when the vehicle controller is disassembled.
1. A vehicle controller having a modification prevention device, the vehicle controller comprising:
a printed circuit board;
a security module frame seated on the printed circuit board and having a plurality of coupling holes; and
security modules inserted into coupling holes of the plurality of coupling holes and configured to electrically communicate with a circuit of the printed circuit board, wherein the security modules include non-conductive insertion pins and conductive insertion pins inserted into the coupling holes, and the non-conductive insertion pins and the conductive insertion pins are scattered while being separated from the coupling holes of the security module frame when the vehicle controller is disassembled.
2. The vehicle controller of claim 1 , wherein the non-conductive insertion pins and the conductive insertion pins are equal in dimension, shape, and color so that the non-conductive insertion pins and the conductive insertion pins are not distinguishable from each other.
3. The vehicle controller of claim 1 , wherein the non-conductive insertion pins and the conductive insertion pins are inserted into the coupling holes of the security module frame, forming an encrypted pattern when inserted.
4. The vehicle controller of claim 1 , wherein the non-conductive insertion pins and the conductive insertion pins each have a cylindrical shape.
5. The vehicle controller of claim 1 , wherein the non-conductive insertion pins and the conductive insertion pins are inserted into the coupling holes of the security module frame, and then a security module cover is coupled to press upper portions of the non-conductive insertion pins and upper portions of the conductive insertion pins.
6. The vehicle controller of claim 5 , wherein a conductive bottom surface of the security module cover is in contact with the conductive insertion pins to constitute the circuit of the printed circuit board.
7. The vehicle controller of claim 5 , wherein a housing is coupled to surround the printed circuit board and the security module cover.
8. The vehicle controller of claim 1 , wherein one end of the non-conductive insertion pins and one end of the conductive insertion pins each have an elastic portion so that the non-conductive insertion pins and the conductive insertion pins are smoothly separated when the vehicle controller is disassembled.
