A tamper-proof method for electric vehicle speed

Abstract

The invention discloses an electric vehicle speed tampering prevention method, and belongs to the technical field of communications. The electric vehicle speed tampering prevention method includes the following steps that (1) sequence codes are downloaded and obtained through a mobile phone client-side; (2) the sequence codes are sent to an intelligent bi-directional alarm through mobile phone Bluetooth; (3) the intelligent bi-directional alarm judges whether the sequence codes are legal or not, and if the sequence codes are legal, and the sequence codes are sent to a controller; (4) the controller enables the received sequence codes to be stored in an ROM storage space and meanwhile sends the sequence codes to an internal chip of a motor; (5) when a vehicle is started, communication is conducted between the controller and the internal chip of the motor, if the sequence codes of the controller and the sequence codes of the internal chip of the motor are matched, the motor is started, and otherwise the motor is not started. According to the method, unique matching of the motor and the controller is achieved, the problem that an owner increases the speed of the vehicle arbitrarily is avoided, the probability that accidents happen due to the fact that the speed of the vehicle is too fast is lowered, the self-security of the owner is guaranteed, and meanwhile the fame of vehicle manufacturers is maintained.

Description

technical field [0001] The invention relates to a data tamper-proof method, and more specifically, relates to an electric vehicle speed tamper-proof method. Background technique [0002] The electric vehicle drive control system mainly includes batteries, power converters, sensors, controllers and motors, among which the controller is a very important part of the electric vehicle, just like the brain of the electric vehicle, used to control the start, Running, advance and retreat, speed, stop and other electronic devices of electric vehicles. Due to the limitation of the structure of the electric vehicle itself, when the electric vehicle leaves the factory, its upper limit speed has been set, and for driving safety, its speed is generally low. [0003] However, there are many brands of electric vehicles on the market today, and the quality cannot be guaranteed. In order to increase the speed of the vehicle, some car owners, regardless of their own safety, go to the repair s...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of existing electric vehicles that the speed of the vehicle can be increased by replacing the motor or the controller, thereby greatly increasing the probability of accidents, and provides a method for preventing tampering of the speed of the electric vehicle. The technical solution of the present invention is used to realize The only matching between the motor and the controller prevents the owner from raising the speed of the vehicle without authorization, reduces the probability of accidents due to excessive speed, ensures the owner's own safety, and maintains the reputation of the vehicle manufacturer. It is especially suitable for for electric bicycles and electric motorcycles
