Abstract

The invention provides a freeway ramp speed-limiting identification method and system, and a vehicle, and relates to the technical field of the vehicle. The freeway ramp speed-limiting identificationmethod comprises the following steps: acquiring a visible speed-limiting sign of a road located by the vehicle; identifying whether the ramp speed-limiting sign is existent in the speed-limiting sign;if the ramp speed-limiting sign is existent in the speed-limiting sign, judging driving intention of a driver; and displaying the speed-limiting information on the ramp speed-limiting sign when judging that the driver has the driving intention of entering the ramp corresponding to the ramp speed-limiting sign. In the identification method and system provided by the invention, the driving intention of the driver is imported, whether the driver has the intention of entering the ramp can be determined by judging the driving intention; if the driver has the intention of entering the ramp, the ramp speed-limiting information is displayed according to the identified ramp speed-limiting sign; and the ramp speed-limited information is not displayed if the driver has no the intention, and the display accuracy rate of the speed-limiting information can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method, system and vehicle for speed limit identification of high-speed ramps. Background technique [0002] Ramp, usually refers to a section of connecting road that provides vehicles entering and exiting the main line and adjacent auxiliary roads or other main lines, such as high-speed entrance and exit ramps, elevated entrance and exit ramps. Due to the particularity of the ramp, in order to ensure driving safety, the speed limit signs of the ramp are usually arranged at the entrance and exit of the ramp and inside the ramp. [0003] In the prior art, the ramp speed limit sign recognition system mainly detects the ramp speed limit information through the navigation system. In the actual test process, after the vehicle has entered the ramp, the ramp speed limit sign recognition system does not prompt the speed limit information, or the vehicle is still Driving on the main r...
