specific Embodiment approach 1

[0016] The vehicle trajectory smoothing control method based on the Internet of Vehicles oriented to fuel saving in this embodiment, combined with figure 1 Shown flow chart, described method is realized through the following steps:

[0017] Step 1. Determine the control area division method, wherein the control area division method includes basic area division and control point optimization methods; it has a significant impact on the control effect of the vehicle trajectory control method;

[0018] Step 2. According to the rules followed by specific vehicle identification, identify specific vehicles in the control area;

[0019] Step 3: Calculating the suggested speed value, and performing vehicle trajectory control on the specific vehicle determined in Step 2 according to the suggested speed value.

specific Embodiment approach 2

[0020] The difference from the first specific embodiment is that, in the fuel-saving Internet of Vehicles-based vehicle trajectory smoothing control method of this embodiment, the basic area division process described in step 1 is as follows:

[0021] Use the DSRC communication method and GPS positioning method to determine the control range of the intersection entrance road, and divide the control area into three basic areas: buffer zone, deceleration zone and acceleration zone; figure 2 As shown in , it is a schematic diagram of the area division of the control area of ​​the intersection entrance road;

[0022] Taking a single single-lane approach road as an example, the position of the vehicle in the control area is detected through DSRC communication. in,

[0023] The function of the buffer zone is to test the communication between the vehicle and the infrastructure, and to predict the trajectory of the vehicle at the same time. The length of the buffer zone is set as L ...

specific Embodiment approach 3

[0031] The difference from the specific embodiment 1 or 2 is that, in the fuel-saving vehicular trajectory smoothing control method based on the Internet of Vehicles in this embodiment, the process of determining the control point position optimization method described in step 1 is as follows:

[0032] The control point position optimization is to determine the three basic areas of the buffer zone, deceleration area and acceleration area through step 1, optimize the control point position according to the fuel saving target, and determine the final length of the three basic areas, specifically:

[0033] Step 11. Introduce the VT-micro vehicle fuel consumption and emission model to calculate the fuel consumption of all vehicles at the intersection. The calculation formula is as follows:

[0034]

[0035] Among them, the VT-micro vehicle fuel consumption and emission model refers to the calculation of instantaneous fuel consumption based on the vehicle's instantaneous speed an...
