Car and neighboring vehicle lane departure warning system and method
A car and a neighboring vehicle lane departure warning system and method are provided. The system includes a cloud server and a plurality of cars connected to the cloud server. Each car includes a vehicle body and a neighboring vehicle lane departure warning apparatus disposed on the vehicle body. The cloud server outputs a reminder signal to the cars within a specific distance of the neighboring vehicle after receiving a neighboring vehicle lane departure message, so that the drivers can be informed in time that the neighboring vehicle moves out of its lane, and can keep a proper distance from the neighboring vehicle in advance to prevent accidents.
1. A neighboring vehicle lane departure warning method, comprising:
when a neighboring vehicle behind a vehicle body on a lane moves out of the lane, a lane departure detection device of the vehicle body detecting a lane departure state of the neighboring vehicle and generating a neighboring vehicle lane departure message; a processor controlling a warning unit on the vehicle body to output a warning signal after receiving the neighboring vehicle lane departure message.
2. The neighboring vehicle lane departure warning method as claimed in claim 1 , wherein the warning signal is displayed on a front windshield of the vehicle body.
3. The neighboring vehicle lane departure warning method as claimed in claim 1 , wherein the lane departure detection device generates the neighboring vehicle lane departure message when a neighboring vehicle in front of the vehicle body moves out of the lane; the lane departure detection device generates the neighboring vehicle lane departure message when a neighboring vehicle on the left, right, front left, rear left, front right or rear right of the vehicle body moves out of its lane next to the lane.
4. The neighboring vehicle lane departure warning method as claimed in claim 1 , wherein the processor receives the neighboring vehicle lane departure message and uploads it to a cloud server, and the cloud server outputs a reminder signal to a car within a specific distance of the neighboring vehicle after receiving the neighboring vehicle lane departure message.
5. A car for performing the neighboring vehicle lane departure warning method as claimed in claim 1 , comprising:
a vehicle body;
at least one lane departure detection device, disposed on the vehicle body, the lane departure detection device having a detection range behind the vehicle body, wherein when a neighboring vehicle on a lane on which the vehicle body is traveling moves out of the lane, the lane departure detection device detects a lane departure state of the neighboring vehicle and generates a neighboring vehicle lane departure message;
a processor, electrically connected to the lane departure detection device and configured to receive the neighboring vehicle lane departure message;
a warning unit, disposed on the vehicle body and electrically connected to the processor, the processor controlling the warning unit to output a warning signal after receiving the neighboring vehicle lane departure message.
6. The car as claimed in claim 5 , wherein the warning unit is a head-up display for displaying the warning signal on a front windshield of the vehicle body.
7. The car as claimed in claim 5 , wherein the lane departure detection device is disposed around a periphery of the vehicle body, the lane departure detection device generates the neighboring vehicle lane departure message when a neighboring vehicle in front of the vehicle body moves out of the lane or when a neighboring vehicle on the left, right, front left, rear left, front right or rear right of the vehicle body moves out of its lane next to the lane.
8. A neighboring vehicle lane departure warning system, comprising:
a cloud server;
a plurality of cars connected to the cloud server;
each car including a vehicle body and a neighboring vehicle lane departure warning apparatus disposed on the vehicle body, the neighboring vehicle lane departure warning apparatus including:
a lane departure detection device, having a detection range around the vehicle body, wherein when a neighboring vehicle on a lane on which the vehicle body is traveling or on an adjacent lane moves out of its lane, the lane departure detection device detects a lane departure state of the neighboring vehicle and generates a neighboring vehicle lane departure message;
a processor, electrically connected to the lane departure detection device, the processor being configured to receive the neighboring vehicle lane departure message and upload the neighboring vehicle lane departure message to the cloud server;
a warning unit, disposed on the vehicle body and electrically connected to the processor, the processor controlling the warning unit to output a warning signal after receiving the neighboring vehicle lane departure message;
the cloud server outputting a reminder signal to the cars within a specific distance of the neighboring vehicle after receiving the neighboring vehicle lane departure message.
9. The neighboring vehicle lane departure warning system as claimed in claim 8 , wherein the warning signal is displayed on a front windshield of the vehicle body.
10. The neighboring vehicle lane departure warning system as claimed in claim 8 , wherein the specific distance is 1 kilometer.
