Embodiment Construction

[0007] The present invention provides a kind of anti-theft scheme of hybrid electric vehicle, and it comprises the steps:

[0008] Step 1: Determine the position of the car key at the ignition switch, the ignition switch has: a power start position (ON position), a power shutdown position (OFF position), and an electrical power supply position (ACC position);

[0009] This step judges whether the key is in the correct position, and prevents misoperation from starting, that is, only when the key is in the ON position, does the judgment of whether to start and subsequent steps.

[0010] Step 2: Only when the car key is in the power start position (ON position), the gearbox controller (TCU) is in an active state and sends the encrypted information in the car key to the anti-theft controller (IMMO ECU) send;

[0011] In this step, correspondingly when the car key is in the power off position (ON position) or the electrical power supply position (ACC position) or the car key is no...

Abstract

An antitheft scheme for a hybrid electric vehicle comprises the following steps that the position of an automobile key on an ignition switch is judged; only when the automobile key is in the power start position, a gearbox controller is in an activation and sends enciphered information in the automobile key to an antitheft controller; the antitheft controller compares the enciphered information with standard information; and the antitheft controller feeds a comparative result signal back to the gearbox controller. According to the scheme, encryption verification is mainly conducted between the antitheft controller and the gearbox controller, and the full vehicle antitheft function is achieved by controlling suction closing of a clutch based on a verification result.

Description

technical field [0001] The invention relates to an anti-theft scheme for a hybrid electric vehicle. Background technique [0002] With the development of the economy and the progress of science and technology, the simple vehicle anti-theft scheme can no longer meet the existing requirements. Automobile manufacturers are all committed to developing vehicle anti-theft systems with higher security levels. [0003] Compared with traditional vehicles, an important feature of hybrid vehicles is that they are equipped with electric drive systems that can save energy and improve power performance, including charging systems, energy storage systems (power batteries), electric drive systems (drive motors) , motor controller and DC / DC), etc. [0004] The existing vehicle anti-theft solution is to implement encrypted authentication between the engine management system (EMS) and the anti-theft controller (IMMO ECU) to achieve vehicle anti-theft, but this solution cannot meet the anti-th...
