The invention relates to an intelligent automobile key based on a gyroscope, a pedometer and UWB, which comprises a key body, a control module and an execution module, and the key body, the control module and the execution module are in communication connection; an angular velocity sensing module, a step counting module, a display module, a UWB module, a wireless cellular network module, a Bluetooth module and a wireless transceiver module are arranged in the key body; a control chip is arranged in the control module and used for controlling the key body to enable the execution module to execute operation. According to the intelligent automobile key based on the gyroscope, the pedometer and the UWB, the angular velocity sensing module, the pedometer module and the UWB module are used for searching an automobile under the conditions that the background of a cellular network does not exist and the automobile is far away, a user can conveniently search the automobile on the sea or in a desert or a deep well, and the problems that the user difficultly finds the automobile in a long distance, and the user experience is poor can be solved. Under the conditions that a cellular network exists and no cellular network exists, the two technologies are combined, and vehicle searching without visual distance and barrier can be achieved.

    本发明涉及一种基于陀螺仪、计步器和UWB的智能汽车钥匙,包括钥匙本体、控制模块和执行模块,所述钥匙本体、控制模块以及执行模块之间通信连接;所述钥匙本体内置有角速度传感模块、计步模块、显示模块、UWB模块、无线蜂窝网模块、蓝牙模块和无线收发模块;所述控制模块内置有控制芯片,用以对钥匙本体提供控制使执行模块执行操作。该基于陀螺仪、计步器和UWB的智能汽车钥匙,在无蜂窝网的背景且距离车辆较远的情况下,利用角速度传感模块、计步模块和UWB模块来对车辆进行寻找,用户在海上,或者沙漠或者深井中都能方便对车辆进行寻找,可以解决用户远距离找车难,已经在有蜂窝网和没有蜂窝网的情况下,两种技术的结合,能达到无视距,无障碍的寻车。
