The invention discloses an accurate positioning keyless entry and starting system and method. The method comprises the following steps: 1), determining the position of a remote control key according to three infrared radio frequency radiation receivers arranged in a vehicle; 2), determining functional areas, and placing keys at the boundaries of the functional areas to be delimited to accurately calibrate each functional area, the functional area comprising an active identification area, a passive identification area, a starting functional area, an in-vehicle function forbidding area and an in-vehicle outline area; 3) according to the calibration of each functional area, endowing the corresponding authority to each functional area where the key is located, and according to the position where the key is located, determining the functional area where the key is located and the corresponding authority to ensure the control accuracy of keyless entry and starting; and 4), if the key is located in the function forbidding area, sending out related prompts by the vehicle HMI. The position where the key is located is accurately determined according to key emission signal intensity transmission path losses, and the key-free entering and starting work interval is accurately calibrated.

    本发明公开了一种精确定位无钥匙进入及启动系统及方法,该方法包括以下步骤:1)根据设置在车内的三个红外射频辐射接收器,确定遥控钥匙所在位置;2)确定功能区域,在需要划定的功能区域边界处放置钥匙精确标定各个功能区域;所述功能区域包括主动识别区、被动识别区、启动功能区、车内功能禁止区和车内轮廓区;3)根据各个功能区域标定,赋予钥匙所在各个功能区的对应权限,根据钥匙所在的位置,确定钥匙所在的功能区域及对应权限,保证无钥匙进入及启动的控制精确性;4)若判断钥匙在功能禁止区,由车辆HMI发出有关提示。本发明根据钥匙发射信号强度传输路径损耗,精确确定钥匙所在位置,精确标定了无钥匙进入和启动工作区间。
