When the vehicle speed of the mobile vehicle 110 is less than or equal to the preset speed, the warning light 410 and the buzzer 420 can be activated at the same time; when the vehicle speed is greater than the preset speed, the buzzer 420 stops and only the warning light 410 can be activated.

For example, referring to Figure 3, when the moving vehicle 110 is moving straight (the direction light 500 is not activated), if any one of the first sensor U1, U2 and the second sensor U3, U4 senses an object 120. The warning light 410 sends out a light warning message. Referring to Figure 4, when the mobile vehicle 110 wants to turn right (the direction light 500 is activated) and the vehicle speed is less than or equal to the preset speed, if any of the first sensors U1, U2 and the second sensors U3, U4 When the first object 120a (bicycle) is sensed and any one of the first distance and the second distance is less than or equal to the second preset distance (120 cm), the warning light 410 and the buzzer 420 will respectively emit light warning messages and sounds Warning message. Referring to Figure 5, when the mobile vehicle 110 wants to turn right (the direction light 500 is activated) and the vehicle speed is less than or equal to the preset speed, if the first sensor U1 senses the second object 120b (pedestrian) and the first distance is less than Equal to the first pre Set the distance (150 cm), the warning light 410 will send out a light warning message to avoid the problem of driving being blocked by the vehicle body of the mobile vehicle 110 (such as the blind area of the A-pillar) and not paying attention to the second object 120b.

It can be seen from the above implementations that the present invention has the following advantages: First, the trapezoidal warning area is used to detect objects and send warning messages to remind driving, which not only enables the driver to brake immediately or take corresponding measures to avoid danger, but also solves the problem of the past Driving is obscured by the body of the moving vehicle without noticing the object, which is prone to dangerous problems. Secondly, the progressive sound and light effect reminds the driver, which not only allows the driver to instantly understand the surrounding conditions of the mobile vehicle, but also allows the driver to quickly know the distance and level of the object. Third, the location where the first sensor and the second sensor are installed is close to the location where the direction lamp is installed, and the first sensor and the second sensor are located below the direction lamp, which can simplify installation The routing. Fourth, use the turn-on light to determine whether the buzzer emits a sound warning message. When the driver does not turn on the turn-on light, the buzzer stops and only the warning light can be activated, which can prevent ordinary cars or pedestrians from approaching moving vehicles. A situation that causes driving troubles due to tweets occurs.
