Dynamic automatic drive lane-changing trajectory planning method based on real-time environment information

The invention discloses a dynamic automatic drive lane-changing trajectory planning method based on real-time environment information. A rollover limitation trajectory vertical coordinate, an optimal trajectory and a collision avoidance trajectory terminus security area are calculated; the relation between the rollover limitation trajectory vertical coordinate and the security area is compared, the positional relation between the optimal trajectory vertical coordinate and the security area is further compared, and then lane-changing decision-making is conducted. According to the dynamic automatic drive lane-changing trajectory planning method based on the real-time environment information, and a polynomial trajectory equation which dose not depend on time is adopted to represent a lane-changing trajectory curve, so that the problem that hypotheses of a speed and an accelerated speed are too strong is avoided; furthermore, collision avoidance algorithm and rollover prevention algorithm which are based on reaction time are introduced to guarantee security of lane-changing; then the optimal trajectory in a safe trajectory cluster is determined through real-time speed adjusting; and finally, an optimal lane-changing trajectory of real-time dynamic state is output through a trajectory generation module to guide an autonomous vehicle to complete a lane-changing behavior, and therefore a set of complete dynamic autonomous vehicle lane-changing trajectory planning module is built.

Method and device of providing parking service to vehicles without license plates

The invention discloses a method and a device of providing parking service to vehicles without license plates. The method comprises steps that information about a current vehicle driving into an entrance lane transmitted by a vehicle detection device disposed on an entrance of a parking lot is received, and therefore a license plate identification device disposed on the entrance of the parking lot is used to identify the license plate information of the current vehicle; when the identification result of the license plate identification device is that the current vehicle does not have the license plate or the license plate information cannot be identified, a provisional certificate disposed on the entrance of the parking lot is used to output a provisional certificate, which is received by the owner of the current vehicle; the provisional certificate at least comprises the entrance identification information, the entrance time information, and the parking lot information of the current vehicle; when the above mentioned owner of the current vehicle transmits the information of receiving the provisional certificate, the current vehicle is released to enter the parking lot. The effective parking service is provided to the vehicles without the license plates, and the competitiveness and the benefits of the parking lot are improved.

Intersection multiline public traffic vehicle priority request conflict coordination control method

The invention discloses an intersection multiline public traffic vehicle priority request conflict coordination control method. By aiming at an intersection with the multiline public traffic vehicle priority request conflict and comprehensively considering factors such as travel time delay of vehicles, priority strategies and the road grade, a real-time multiline priority request conflict coordination control strategy is established. Only when travel time delay of one public traffic vehicle exceeds a certain threshold value, a priority request meets the limiting condition and the benefit brought by priority is higher than delay caused by the priority, the public traffic vehicle sends a priority request signal; when a multiline priority request is generated, a priority level evaluation model is utilized to sort conflicted priority requests, and the priority of passing is given to a line with the highest priority level. On one hand, the problem of unfairness of an original multiline priority request conflict solution is solved; on the other hand, parameters which the method relates to are fewer and are very easy to obtain, a complex algorithm, an optimizing process and the like are not required, practicality is high, and operating efficiency of an urban public traffic system can be greatly improved.
