Vehicle speed control method and system for ramp, vehicle and storage medium

The invention relates to the technical field of automatic driving, and discloses a vehicle speed control method and system for a ramp, a vehicle and a storage medium. According to the method, navigation map information including a ramp speed limiting road section and real-time position information is obtained, and if the current vehicle runs in the ramp speed limiting road section, the current vehicle is driven to the ramp speed limiting road section; if yes, determining a speed limit flag bit between the current vehicle and the ramp speed limit road section according to the real-time position information, then matching a target vehicle speed threshold value according to the speed limit flag bit, and controlling the real-time vehicle speed of the current vehicle within the target vehicle speed threshold value so as to limit the speed of the current vehicle. The navigation map is used as a basis to determine the position relationship between the current vehicle and the target ramp, and then the target vehicle
