Cloud-based network optimizer for connected vehicles
摘要
說明書
A BSM is broadcasted over the 5.9 GHz DSRC band. DSRC range may be substantially 1,000 meters. In some embodiments, DSRC range may include a range of substantially 100 meters to substantially 1,000 meters. DSRC range is generally 300 to 500 meters depending on variables such as topography and occlusions between DSRC-equipped endpoints. In some embodiments, one or more of the vehicles 123, 124 depicted in
Referring now to
A BSM may include two parts. These two parts may include different BSM data 197 as shown in
Part 1 of the BSM data 197 may describe one or more of the following: the GPS data 192 of the vehicle; vehicle heading; vehicle speed; vehicle acceleration; vehicle steering wheel angle; and vehicle size.
Part 2 of the BSM data 197 may include a variable set of data elements drawn from a list of optional elements. Some of the BSM data 197 included in Part 2 of the BSM are selected based on event triggers, e.g., anti-locking brake system (“ABS”) being activated may trigger BSM data 197 relevant to the ABS system of the vehicle.
In some embodiments, some of the elements of Part 2 are transmitted less frequently in order to conserve bandwidth.
In some embodiments, the BSM data 197 included in a BSM includes current snapshots of a vehicle.
