The invention discloses a reminding
system for preventing a dead zone caused by keeping out of a heavy vehicle and a work method of the reminding
system. The reminding
system comprises a travelling vehicle, the traveling or stopped heavy vehicle and a laterally-coming obstacle, front sensors are mounted at the front end of the travelling or stopped heavy vehicle,
laser transmitters are mounted onrear view mirrors of the travelling or stopped heavy vehicle, and lateral sensors are mounted on the left side and the right side of the traveling or stopped heavy vehicle. The specific method comprises the steps of detection of the front sensors, judgment of a dangerous state, judgment of the dangerous state, judgment of the moving direction of the obstacle, work of the
laser transmitters and turning off of lasers. The sensors and the
laser transmitters are additionally mounted on the heavy vehicle, so that the front or lateral state of the heavy vehicle is perceived, the laser transmitters are utilized to transmit
laser beams to provide dead zone information reminding for the
peripheral vehicle, thus a driver rapidly obtains dead zone information and decelerates the vehicle in time underthe premise that attention is not changed, and
sight does not leave from the front position and the
view angle, the
traffic accident is avoided, responding is sensitive, and the safety is high.
