Integrated central control system for driving electric vehicle and electric vehicle with integrated central control system

Abstract

The invention provides an integrated central control system for driving an electric vehicle and the electric vehicle with the integrated central control system. The system comprises a central control circuit board provided with a main control chip, and the central control circuit board is provided with a DCDC module, an anti-theft module, a vibration module and a communication module which are connected into the main control chip; under the control instruction output by the main control chip, the DCDC module gives one or more controllable power supply output signals based on the state control of the motor of the electric vehicle; an anti-theft module takes a wheel movement signal as an input signal and detects and recognizes a vibration signal through a vibration module, and the main control chip judges whether a bicycle locking instruction needs to be sent to the motor controller or not based on the wheel movement signal, the vibration signal, an electric door lock signal and an externally input anti-theft instruction. Through the specific control design, the integration of the DCDC power supply control module, the anti-theft control module and the vibration module is realized on the basis of the central control structure, the number of single chip microcomputer circuit boards is reduced, the wire harness structure is also obviously simplified, and the driving performance of the electric vehicle is not influenced.

[0002] In the field of drive control of electric vehicles, in order to meet the control needs of various functions of electric vehicles, it usually includes the need to set up independent motor control modules, DCDC power supply control modules, anti-theft control modules, etc. The controller module formed by the circuit board also needs to lead out the wiring harness to be electrically connected to other controller modules. Obviously, this not only needs to consume more single-chip circuit boards, but also the cost of the wiring harness is high, and it also causes inconvenience to subsequent use and maintenance.

[0003] However, the applicant found that when the central control needs to integrate a DCDC power supply control module and an anti-theft control module, it will face many technical problems, mainly including: first, DCDC modules currently on the market generally use asynchronous BUCK circuits, through Schottky Diode freewheeling, the difficulty of this kind of circuit is that the upper tube drive and current sampling must pass through the optical isolation method or the magnetic isolation method of the transformer. The efficiency of the diode freewheeling is low, and the voltage drop on the diode is relatively large. The conduction loss of the base diode is still very large; second, the existing anti-theft module generally uses the received 433 signal in the market to decode the anti-theft signal through a dedicated chip, and separate the anti-theft signal from the electric door lock and wheel sent by the controller. Compared with dynamic signals, the state is obtained, and then it is decided whether to lock the car for anti-theft, so it is difficult to integrate into the central control module
