Abstract
The invention relates to an anti-theft system and an anti-theft method of a hybrid electric vehicle. The anti-theft system comprises an engine, an ISG (Integrated Starter Generator), a drive motor and an HCU (Hybrid Control Unit), wherein the engine, the ISG and the drive motor are respectively connected with an EMS (Engine Management System), an ISG controller and a drive motor controller on the vehicle, the EMS, the ISG controller and the drive motor controller are communicated with the HCU through a high-speed CAN (Controller Area Network) bus, and encryption security modules are loaded on the EMS, the ISG controller, the drive motor controller and a car body controller. The anti-theft method comprises the following steps of: 1) authenticating a key; 2) authenticating a power device; and 3) after three responses are completely correct, outputting a torque by a power system. The anti-theft system and the anti-theft method, provided by the invention, have the advantages that: through carrying out anti-theft authentication on the EMS, the ISG controller and the drive motor controller simultaneously, possibility of starting the vehicle by any one power source in the hybrid electric vehicle is avoided, and the reliability of a car security system is greatly improved..
Description
Technical field
The present invention relates to the vehicle anti-theft technical field, be specifically related to a kind of hybrid vehicle anti-theft system and method.
Background technology
Driving engine is the unique drive source of automobile that transmission internal combustion engine drives, therefore antitheft authentication occurs over just between car body controller and the engine management system (EMS), after only having authentication between the two to pass through, EMS just can carry out the action of the control engine operation such as oil spout igniting.Yet, hybrid vehicle, when especially having driving engine, ISG motor (or BSG motor) and three propulsions source of main drive motor in the hybrid power system configuration, all there is the possibility of starting vehicle in three kinds of propulsions source, need the anti-theft system of redesign vehicle.
Summary of the invention
The purpose of this invention is to provide a kind of hybrid vehicle anti-theft system and method, to overcome present prior art hybrid vehicle anti-theft system above shortcomings.
The objective of the invention is to be achieved through the following technical solutions:
A kind of hybrid vehicle anti-theft system, comprise driving engine, ISG(Integrated Starter Generator, Integrated starter alternator), drive motor, HCU (Hybrid Control Unit, entire car controller) and car body controller, described driving engine, ISG and drive motor respectively with vehicle on EMS, the ISG controller is connected MCU with drive motor controller) connect, EMS, ISG controller and drive motor controller all are connected by the high-speed CAN bus communication with HCU, HCU is connected by the high-speed CAN bus communication with car body controller, car body controller (BCM) is connected with key coil on the vehicle, described driving engine, ISG, drive motor, ISG controller and drive motor controller all are connected described EMS with electrokinetic cell on the vehicle, the ISG controller, drive motor controller and car body controller all are loaded with the encrypted antitheft module.
Hybrid vehicle theft preventing method of the present invention may further comprise the steps:
1) key authentication: after chaufeur inserted key, recognition coil on the key and car body controller authenticated to confirm the correctness of key;
2) engine installation authentication: after the key authentication is passed through, car body controller sends antitheft request to EMS, ISG electric machine controller and drive motor controller, three engine installation controllers are found the solution according to the cryptographic algorithm of setting, and respond the request of car body controller; And
3) after three responses were entirely true, power system can be exported torque.
Beneficial effect of the present invention is: the present invention is by carrying out antitheft authentication to EMS, ISG controller and drive motor controller simultaneously, actv. has prevented that there is the possibility that starts vehicle in any one propulsion source in the hybrid vehicle, improve greatly the reliability of automotive theft proof system, also can eliminate the stolen potential safety hazard of vehicle fully simultaneously.

The below is described in further detail the present invention with reference to the accompanying drawings.
Fig. 1 is the structured flowchart of the described a kind of hybrid vehicle anti-theft system of the embodiment of the invention;
Fig. 2 is the antitheft authentication sequential chart of the described a kind of hybrid vehicle anti-theft system of the embodiment of the invention.
Among the figure:
1, driving engine; 2, ISG; 3, drive motor; 4, HCU; 5, car body controller; 6, EMS; 7, ISG controller; 8, drive motor controller; 9, key coil; 10, electrokinetic cell; 11, encrypted antitheft module.
The specific embodiment
As shown in Figure 1, the described a kind of hybrid vehicle anti-theft system of the embodiment of the invention, comprise driving engine 1, ISG 2, drive motor 3, HCU 4 and car body controller 5, described driving engine 1, ISG 2 and drive motor 3 respectively with vehicle on EMS 6, ISG controller 7 is connected connection with drive motor controller, EMS 6, ISG controller 7 is connected with drive motor controller and all is connected by the high-speed CAN bus communication with HCU 4, HCU 4 is connected by the high-speed CAN bus communication with car body controller 5, car body controller 5 is connected with key coil 9 on the vehicle, described driving engine 1, ISG 2, drive motor 3, ISG controller 7 is connected with drive motor controller all and is connected described EMS 6 with electrokinetic cell 10 on the vehicle, ISG controller 7, drive motor controller 8 and car body controller 5 all are loaded with encrypted antitheft module 11.
As shown in Figure 2, provided the sequential relationship of each controller action of anti-theft system, when ignition lock forwarded the ACC shelves to, recognition coil on the key and car body controller 5 carried out the correctness authentication of key, only after authentication was passed through, the antitheft verification process between the subsequent control device just can carry out.After key forwards the IGN shelves to, the controller of power system begin initialization and the communication carried out each other synchronous.Car body controller 5 sends authentication request afterwards, and HCU 4 is forwarded to ISG controller 7 and drive motor controller 8 on another road high-speed CAN bus with this request.EMS 6, ISG controller 7 and drive motor controller 8 respond according to the cryptographic algorithm of setting, after car body controller 5 confirms that the response of above-mentioned three controllers is correct, send the zone bit that antitheft authentication is passed through, HCU 4 is after acknowledging receipt of this zone bit and receiving key Start signal, resolve driver intention and send torque request to EMS6, ISG controller 7 and drive motor controller 8, power system can be exported torque.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within protection scope of the present invention.
