The invention provides a vehicle keyless entry method and system and a vehicle. In the vehicle keyless entry method, after a low-frequency driving unit receives a trigger signal sent by a vehicle door lock trigger unit, a low-frequency antenna group is driven to send a low-frequency signal which can be received by a vehicle key according to low-frequency data corresponding to the trigger signal; meanwhile, the low-frequency driving unit sends an interrupt request signal to wake up the MCU; the MCU obtains the trigger signal from the low-frequency driving unit and controls the vehicle door locking device to be opened after receiving feedback information of a vehicle key, or the MCU is dormant after not receiving the feedback information of the vehicle key, and the MCU sends low-frequency data to the low-frequency driving unit before dormancy. According to the vehicle keyless entry method, the MCU transmits the low-frequency data to the low-frequency driving unit before dormancy, so that the interaction time of the MCU and the low-frequency driving unit can be saved, the waiting time of a keyless opening process is saved, and better experience is provided for customers.
本发明提供了一种车辆无钥匙进入方法及系统和车辆,本发明的车辆无钥匙进入方法中,低频驱动单元接收车门锁触发单元发送的触发信号后,依据与触发信号对应的低频数据驱动低频天线组发送可被车辆钥匙接收的低频信号,同时低频驱动单元发送中断请求信号唤醒MCU;MCU自低频驱动单元获取触发信号,并在接收到车辆钥匙的反馈信息后控制车门锁闭装置开启,或在未接收到车辆钥匙的反馈信息后休眠,且MCU在休眠前将低频数据发送至低频驱动单元。本发明所述的车辆无钥匙进入方法,MCU在休眠前将低频数据传输给低频驱动单元,因而可节约MCU和低频驱动单元的交互时间,从而节约无钥匙开启过程的等待时间,并给予客户更良好的体验。
