The invention discloses a living body detection method, an automobile domain controller and an automobile, a detection radar is arranged on a rotatable ceiling screen, the detection area of the detection radar is changed through rotation of the ceiling screen, the whole in-vehicle space of the automobile can be detected by a single detection radar, and the living body detection cost of the automobile is reduced. When the automobile is in a power-off locking working condition, the detection radar is firstly controlled to carry out preliminary living body detection on the automobile, when the preliminary detection result is that the living body feature exists, the position interval of the living body feature is determined according to the current rotation angle of the ceiling screen, and then the ceiling screen is controlled to rotate to the preset angle with the best detection precision of the detection radar. And controlling the detection radar to perform deep living body detection on the position interval, and outputting a first alarm signal when the depth detection result is that the living body feature exists. Therefore, the accuracy of in-vivo detection of the automobile can be effectively improved, whether a person exists in the automobile after the automobile is powered off and locked or not is accurately judged, and the safety of the automobile during power-off and locking is improved.

    本申请公开了一种活体检测方法、汽车域控制器和汽车,通过将探测雷达设置于可旋转的吸顶屏上,通过吸顶屏的旋转改变探测雷达的探测区域,能够实现由单个探测雷达探测汽车整个车内空间,降低对汽车进行活体检测的成本。在汽车处于下电锁车工况时,先控制探测雷达对汽车进行初步活体检测,在初步检测结果为存在活体特征时,根据吸顶屏当前旋转角度确定活体特征的位置区间,进而控制吸顶屏旋转至探测雷达的探测精度最佳的预设角度,控制探测雷达对位置区间进行深度活体检测,在深度检测结果也为存在活体特征时,输出第一报警信号。由此,能够有效提高汽车活体检测的精度,准确地判断汽车下电锁车后内部是否还有人员,提高汽车下电锁车的安全性。
