在一些实施方式中，传感器模块210包括但不限于激光雷达、毫米波雷达及相机等。组合导航模块220包括但不限于全球导航卫星系统(Global Navigation SatelliteSystem，GNSS)、惯性传感器(Inertial Measurement Unit，IMU)等。此外，自动驾驶系统200还可以包括车载单元(On Board Unit，OBU)等，此处不做限定。In some embodiments, the
其中，激光雷达包括发射单元、接收单元和信息处理单元，发射单元用于发射探测信号即激光束，发射的信号经探测体反射被所述接收单元接收，再由信息处理单元将反射回来的信号与发射信号进行比对并处理后，就可以获知目标的有关信息，例如，目标距离、方位、高度、速度、姿态、甚至形状等参数，从而对目标进行识别。在一些实施方式中，激光雷达需要12V稳压的电源进行供电。Among them, the laser radar includes a transmitting unit, a receiving unit and an information processing unit. The transmitting unit is used to transmit a detection signal, that is, a laser beam. The transmitted signal is reflected by the detection body and is received by the receiving unit, and then the reflected signal is returned by the information processing unit. After comparing and processing with the transmitted signal, the relevant information of the target can be obtained, for example, parameters such as target distance, orientation, height, speed, attitude, and even shape, so as to identify the target. In some embodiments, the lidar requires a regulated 12V power supply for power.
毫米波雷达可采用级联方式工作，这方式可以使得毫米波雷达呈现出清新的360度全景图像，还可以跟踪上千目标。并且毫米波雷达应对复杂环境的能力最强，因此，为了保证安全，可额外增加一个毫米波雷达作为冗余系统，在其他传感器即摄像机和激光雷达等都失效的情况下，依然能够安全行驶到路边停车。在一些实施方式中，毫米波雷达需要12V稳压的电源进行供电。Millimeter-wave radars can work in a cascaded manner, which allows the millimeter-wave radars to present a fresh 360-degree panoramic image and track thousands of targets.

In some embodiments, the camera requires a regulated 5V power supply for power.
需要说明的是，由于激光雷达的分辨率高，但是容易受天气影响，而毫米波雷达分辨率低，但是不受天气影响，因此可以将激光雷达为基础，毫米波雷达用来补充，来探测车辆周围障碍物(比如，车辆、行人、电动车)。其中，雷达主要用于探测中长距离的物体，而相机主要拍摄近距离的物体，用于和雷达相互补充。当然，其他实施方式中，相机也可以用于拍摄远处图像，以感知探测物体。It should be noted that since the resolution of lidar is high, but it is easily affected by the weather, while the resolution of millimeter-wave radar is low, but it is not affected by the weather, so lidar can be used as the basis, and millimeter-wave radar can be used as a supplement to detect Obstacles around the vehicle (eg, vehicles, pedestrians, electric vehicles). Among them, the radar is mainly used to detect medium and long-distance objects, and the camera is mainly used to shoot close-up objects to complement the radar. Of course, in other implementations, the camera can also be used to capture distant images to perceive the detected object.
