Prompting device preventing vehicle from colliding with non-motor vehicles during turning

The utility model discloses a prompting device preventing a vehicle from colliding with non-motor vehicles during turning. A moving state of the vehicle is monitored in real time through a steering wheel turning angle sensor and a speed sensor, and when the turning angle of a steering wheel is larger than a certain value, the vehicle is about to turn in a large degree. Two laser radars are simultaneously used for monitoring the left rear side area and the right rear side area of the vehicle, data of the laser radars are sent to the a microprocessor, and the microprocessor collects the data in real time and judges the data of the laser radars to identify the non-motor vehicles in the rear areas and judge risk of collision between the vehicle and the non-motor vehicles. The prompting device is few in investment cost and suitable for being popularized and used on a large scale. The prompting method of the prompting device has the advantages of being intelligentialized and automated, a driver does not need to conduct any operation, and work reliability is high.
