Description

Vehicle stop warning system, method and computer-readable medium

The present invention relates to a vehicle stop warning technology, and in particular, to a vehicle stop warning system, method and computer-readable medium.

Before a vehicle (such as a bus or other commercial vehicle) is ready to pull into a stop for passengers to get on or off, the vehicle will usually slow down and move to the lane on which the vehicle is currently traveling (such as the inner lane/middle lane). Changing to the lane (such as the outermost lane) or road shoulder at the stop will cause the vehicle to occupy the lane or shoulder at the stop of the road when it stops. It will also affect the traffic flow along the road where the vehicle is traveling. It is easy to cause traffic accidents in which transportation vehicles and surrounding vehicles (such as cars/motorcycles/bicycles, etc.) collide with each other.

In an existing technology, a method and system for smart bus driving management are provided. A client program is installed in the user device of the client, and the client sends reservation information through the client program to reserve the bus before taking the bus. The traffic control unit transmits the bus schedule and stop that the user wants to board to the bus's on-board device, thereby reminding the bus driver of the number of reserved passengers at the next stop, thereby avoiding the problem of non-stop passing at stops.

However, this prior art focuses on the fact that the driver of the bus can directly check the number of reserved passengers at the next stop on the on-board device, and reminds the driver to stop at the stop to wait for passengers to take the bus, but it cannot be carried by the on-board device on the bus. The equipment links the vehicle side display and rear display to send warning messages to vehicles surrounding the bus in advance. It also cannot integrate components such as the driving recording device, driving assistance module and vehicle-mounted equipment's GPS (Global Positioning System) positioning module on the bus. It is also unable to provide data such as the bus's driving time, driving distance, vehicle speed, rotation speed, number of lane deviations, number of turn signal activations, and real-time location. It is also impossible to instantly correct the bus based on the historical data of the bus's driving time and driving distance. The stopping time and stopping distance.

Therefore, how to provide an innovative stop warning technology for transportation vehicles (such as buses or other business vehicles) to solve any of the above problems or provide related functions/services has become a major research topic for those skilled in the art.

Level or warning attention level. For example, the safety level means that transportation vehicle A stops at a safe or risk-free stop, etc., and the warning attention level means that transportation vehicle A stops at a stop that is unsafe, risky, requires attention, or should warn vehicle B (driver), etc.

When the message warning module 34 of the vehicle-mounted device 30 determines that the risk index level of the vehicle A has reached the warning attention level before it is ready to dock, the message warning module 34 can link the vehicle side display 41 of the early warning display device 40 (such as a vehicle Side LED display) and vehicle rear display 42 (such as vehicle rear LED display), so that the message warning module 34 displays at least one warning message M in advance through the vehicle side display 41 and the vehicle rear display 42 to alert the vehicle B surrounding the transportation vehicle A.

The data computing module 33 calculates the progress estimate of the stopping time and the progress estimate of the stopping distance of the transportation vehicle A.

Secondly, the vehicle-mounted device 30 can integrate the driving assistance device 20 to count the number of lane switches of the vehicle A (such as the number of lane switches), and match or combine it with the environmental characteristic coefficient of the road on which the vehicle A travels (such as the road is an urban road). Or different roads such as highways have different environmental characteristic coefficients), the data calculation module 33 of the vehicle-mounted device 30 calculates the risk index level of the vehicle A before it is ready to stop, and then the message warning module of the vehicle-mounted device 30 34 It is determined that the risk index level of transport vehicle A before it is ready to dock is at the safety level or warning level.

When the message warning module 34 of the vehicle-mounted device 30 determines that the risk index level of the vehicle A has reached the warning attention level before it is ready to dock, the message warning module 34 can link the vehicle side display 41 of the early warning display device 40 (such as a vehicle side LED display) and vehicle rear display 42 (such as vehicle rear LED display), so that the message warning module 34 can proactively alert vehicles B around transportation vehicle A through the vehicle side display 41 and vehicle rear display 42 of the early warning display device 40 (The driver) issues (such as a prompt/display) an early warning message M that includes at least one of the stopping time (such as the expected stopping time) and the stopping distance (such as the expected stopping distance) of the transport vehicle A. In another embodiment, the message alert module Group 34 can also transmit the early warning message M to vehicle B around transport vehicle A through wireless communication technology (such as 4G, 5G, etc.), so that vehicle B can react in advance.

For example, before transport vehicle A is ready to stop, it will slow down and switch from the center line of the road to a stop on the sideline or shoulder (such as a stop), thus affecting the traffic flow along the road where transport vehicle A is traveling. The vehicle side display 41 and the vehicle rear display 42 of the early warning display device 40 can actively remind the vehicle B (driver) around the vehicle A (such as the right and rear) before the vehicle A stops, so that the vehicle B (driver) It can change lanes or brake in advance to help reduce the risk or even traffic accidents caused by changes in traffic flow, and vehicle B (driver) around vehicle A (such as on the left) can also use vehicle A to move out of the way as soon as possible. lanes, thereby reducing lane congestion.

The data collection module 32 of the vehicle-mounted device 30 continuously accumulates the historical data of the average travel time and the average travel distance of the vehicle A between the two stations, so that the data calculation module 33 of the vehicle-mounted device 30 calculates the historical data of the vehicle A based on the average travel time between the two stations. The historical data of the average travel time and the average travel distance between the two stations are corrected in real time to the stop time and stop distance of the transportation vehicle A, and then matched or combined with the information of the transportation vehicle A provided or obtained by the driving recording device 10 Data such as driving time, driving distance, vehicle speed (such as driving speed), and the number of lane deviations of transportation vehicle A provided or obtained by the driving assistance device 20 can be further estimated or calculated by the data computing module 33 of the vehicle-mounted device 30 The risk index level of transport vehicle A before it is ready to dock.

For example, the stop warning system 1 of a transportation vehicle is used to warn the surrounding vehicle B (driver) to respond in advance before the transportation vehicle A stops. The present invention can integrate the driving recording device 10 and the driving auxiliary device 20 connected to the vehicle A with the GPS (global positioning system) positioning module 31 of the vehicle-mounted equipment 30, and calculate the transportation data through the data calculation module 33 of the vehicle-mounted equipment 30. Tool A is at the risk index level before it is ready to stop. Risks when transport vehicle A is preparing to dock When the index level has reached the warning attention level, the message warning module 34 of the vehicle-mounted equipment 30 can actively use the vehicle side display 41 (such as the vehicle side LED display) and the vehicle rear display 42 (such as the vehicle rear LED display) of the early warning display device 40. The vehicle B (driver) around the transport vehicle A shall be notified in advance (such as a prompt/display) including at least one of the stop time (such as the expected stop time) and the stop distance (such as the expected stop distance) of the transport vehicle A. The early warning message M is provided to facilitate vehicle B (driver) driving around transport vehicle A to respond in advance to change lanes or brake.

The historical data of the travel distance and the average travel distance of Transport A between the two stops are used to calculate the progress estimate of the stop-to-stop distance of Transport A.

In step P3, the number of lane switching times of transportation vehicle A is counted. That is, the driving assistance device 20 obtains the number of lane deviations and the number of turn signal activations of the vehicle A, and the data calculation module 33 of the vehicle-mounted device 30 matches the number of lane deviations and the number of turn signal activations of the vehicle A or Combined with the environmental characteristic coefficient of the road on which transport vehicle A travels, the number of lane switching times of transport vehicle A can be calculated.

In step P4, the risk index level of transport vehicle A before it is ready to dock is calculated. That is, the data computing module 33 of the vehicle-mounted device 30 uses the driving time, driving distance and number of lane changes of the vehicle A, and matches or combines it with the average driving time of the vehicle A stored in the database 36 of the vehicle-mounted device 30. The historical data and the historical data of the average driving distance are used to instantly correct the stop time and stop distance of transport vehicle A to further calculate the risk index level of transport vehicle A before it is ready to stop, and then the message warning module 34 determines The risk index level of transport vehicle A before it is ready to dock is safety level or warning level.
