[0035] 第五步:如果第四步中接收到的认证信号与所产生的随机滚动码相匹配,所述车载中央处理器则控制所述点火器、中央锁控制器以及发动机控制系统上电工作; [0035] The fifth step: the fourth step if the received rolling code authentication signal generated random matches, then the central processor controls the vehicle ignition, the electrical central locking system controller and an engine control jobs;

[0036] 第六步:通过所述点火器向车载中央处理器发送点火指令,所述车载中央处理器则通过所述发动机控制系统控制汽车发动机点火; [0036] The sixth step: transmitting an ignition command to the ignition of the vehicle by the central processor, said central processor onboard the automobile engine ignition control by the engine control system;

[0037] 第七步:所述车载中央处理器通过所述车载中央处理器判断汽车档位是否处于P 档以及汽车刹车是否踩住,如果汽车档位处于P档同时汽车刹车被踩住,再次按下点火器中的点火按钮,汽车则被开动。 [0037] Seventh Step: The vehicle onboard central processing unit via said central processor determines whether the shift position is in P range automobiles and automotive brakes slam whether, if the car is in the shift position is the P position while the car brakes slam, again ignition button is pressed in the ignition, start the car were.

[0038] 汽车停车时也需要先把档位挂在P档,然后按下点火器按钮,实现停车。 [0038] parking cars need to first gear is engaged in the P range, and then press the button igniter, parking achieved.

[0039] 本发明的显著效果是:系统改变了信息的发送方式,也就是把信息传递部分的通道改为了远程无线传输,这样以来,开启车门锁的时候需要在车载控制系统与感应钥匙系统之间建立身份认证通道,发动机启动时也需要在车载控制系统和感应钥匙系统之间建立身份认证通道,即使有人强行开门进入车内,在没有车钥匙的情况下也不能将汽车启动,使得汽车防盗性能更强,一键启动过程中也通过中央控制锁进行档位判别,避免了误操作引起的汽车启动。 [0039] The significant effect of the present invention are: the system changes the transmission mode information, that is, the channel information transmission section to the remote wireless transmission, so that since the open door lock when the need of the onboard control system and the sensing Key System the establishment of inter-channel authentication, also need to establish authentication channel between the onboard control system and sensor system key when the engine is started, even if someone forced open the door into the car, the car can not start the car without a key situation, making car alarm higher performance, a key to start the process also determined by a central control lock gear, to avoid starting the car caused by misuse.
