77GHz Micro Wave , BSD Blind Spot System MFeatures:The system s millimeter-wave rs to the envment behind and to the sides of the vehicle, the driver's ''field of view'' blind spot, and provide a helpful warning function when the driver is driving normally or changinges.The area is divided into two sections: left and right 4.4m (middle ±1.5m no alarm), rearward 10m is the blind zone ing area, to enter the blind zone movement of the vehicle for early warning, at this time the same side of the LED light is always on, when playing the turn signal, the warning level rises to sound, the same side of the LED light fing.The distance reaches m in the LCAe-changing warning function when the vehicle changeses, the alarm distance reaches 40m, and when there is a target vehicle approaching in the approaching area, and when the collision time between the target vehicle and this vehicle is le than or equal to 5.0s, the silateral LED lights are always on, if you hit the turn signal at this time thee-changing sounds and the silateral LED lights f.Specifications:1.System properties:Working voltage: 9-16VWorking temperature: -40℃ to 80℃Power consumption: 2.5WWaterproof grade: 67Frequency band: 77Hz-79HzRefresh rate: 20HzCommunication interface: UARTBaud rate: 115200Shell size: 28 * 28*28*22.5mm2. performance:Number of s: 3Tx*4RxPitch beam width: 25°Horizontal beam width: 45°3. performance:Range resolution: 0. 2mSpeed resolution: 0.2m/sSpeed measuring range: 200 km/hThe ranging accuracy is better than 0. 2m.Velocity measurement accuracy: better than 0. 2m/sAngle measurement accuracy: better than 1 distance: m4.Blind zone ing function -BSD:System starting speed: V>10Km/h.Horizontal range of early warning: 1.5m < x < 4.4m,-4.4m < x
