Anti-theft electric motorcar controller with electronic poll code

Abstract

The invention relates to an anti-theft electric motorcar controller with an electronic poll code, which is mainly characterized in that: the hardware part of an electric motorcar controller keeps unchanged substantially, while an electronic poll code authentication process is added in control software, namely, an electric control lock automatically inputs the electronic poll code in a password key into the electric motorcar controller in a touch input mode when being unlocked, the controller compares an input electronic password with a digital password stored in a controller chip, and an electric motorcar can be started when the input electronic password and the digital password are consistent and cannot be started when the input electronic password and the digital password are inconsistent. Therefore, a novel electric motorcar controller integrated with a burglar alarm and the controller is formed and has the characteristics of low cost, strong function and good anti-interference performance and anti-theft performance.

Description

Technical field: [0001] The invention belongs to the application invention of computer digital technology in an electric vehicle controller, and in particular relates to an electric vehicle anti-theft controller with an electronic registration code. Background technique [0002] Brushless motor is currently the most popular power source for electric vehicles. The development of its controller is divided into two stages: the first stage is a pure hardware circuit controller using a dedicated chip. This circuit is relatively simple and has been eliminated; The second stage is to use the MCU-based control chip to achieve intelligent control through analog, digital, high-power MOSFET drive and other technologies, which better solves the problem of commutation and load stability caused by the use of brushless motors in electric vehicles. Sexual issues and protection of controllers, motors, and power supplies. However, at present, all electric vehicle controllers do not have more...

Problems solved by technology

However, at present, all electric vehicle controllers do not have more technical breakthroughs in anti-theft control. Most of them retain an anti-theft input interface, control with a level signal, and realize anti-theft control through an external anti-theft control alarm.

There are many defects brought about by this design: first, it only has deterrent effect but no anti-theft effect, and the vehicle can be driven by opening the electric door lock; second, the cost is high, and the additional anti-theft alarm includes two types: on-site alarm and on-site wireless alarm. The relative cost is relatively high; the third is that the anti-interference ability is poor, and the alarm is sent by sensing the instantaneous change of the vehicle, the false alarm rate is too high, and the phenomenon of disturbing the people is serious; the fourth is that due to the limitation of the civilian frequency, the wireless alarm has different communication with other wireless control equipment. The interference probability is very high, and the electric car using the remote control key is an unsolvable problem in the problem of anti-interference theft
