Abstract
The invention discloses an electric vehicle controller with an internal antitheft function. An antitheft circuit is added to the controller, and the core of the antitheft function is a critical voltage value comparison circuit. One input of a comparator is connected with any one phase line through a circuit, the other input of the comparator and a lock head key are connected to establish standard potential, the voltage values of the input ends are different, and the output voltage can also be changed; the output end of the comparator is connected with a chip of the controller through a circuit, and the antitheft function of an electric vehicle is fulfilled through a driving circuit after the chip receives signals. The antitheft purpose can be fundamentally achieved, an existing vehicle lock cracking means has no effect on the antitheft mode, and the electric vehicle cannot be unlocked only if a person does not have a vehicle key. In addition, an antitheft device does not need to be externally arranged on the electric vehicle which is provided with the electric vehicle controller with the internal antitheft function, and therefore the cost of the electric vehicle can be greatly saved.
Description
Technical field
The present invention relates to a kind of controller for electric vehicle, especially a kind of interior antitheft controller for electric vehicle.
Background technology
Along with the development of society and the continuous increase of the fuel oil vehicle, the natural resourcess such as the petroleum fuel faced by the mankind are not enough and fuel emission causes the problem of global warming day by day to highlight.So the traffic of hybrid power or pure power is total to the life that transportation means enters into people gradually in this context, battery-driven car arises at the historic moment.
Battery-driven car, because having environmental protection, fast and easily feature, is well received by consumers.Along with the increase of battery-driven car quantity, the stolen quantity of battery-driven car also increases year by year, and electric vehicle anti-theft problem is abnormal severe.Facing to the progress of science and technology, for tackling robber's driving skills art of constantly upgrading, people investigated various Car Burglar Alarm.Current Car Burglar Alarm can be divided into two classes according to structure: mechanical alarm device and electronic type Car Burglar Alarm.Mechanical type anti-theft device realizes antitheft object mainly through locking handlebar, tire and motor; Electronic type Car Burglar Alarm mainly through dedicated remote control to Car Burglar Alarm signal, Car Burglar Alarm again by signal transmission to controller, realize antitheft object by controller.
There is following problem in the Car Burglar Alarm of above-mentioned two kinds of structures: the core of (1) mechanical type anti-theft device is a lock, antitheft thorough, and that cracks in means is numerous, can't stop the destruction of the instruments such as hydraulic shear.
(2)electronic type is antitheft to be completed by Car Burglar Alarm and controller two partial cooperations, and time Car Burglar Alarm passes through at cart, thunder etc., wrong report, does not receive signal time distant.
