Problems solved by technology
[0003] Existing electric bicycles, electric motorcycles, and low-speed electric vehicles are not equipped with active braking systems during driving, resulting in traffic accidents such as rear-end collisions and collisions, and because electric bicycles, electric motorcycles, and low-speed electric vehicles are not equipped with The protective device makes electric bicycles, electric motorcycles, and low-speed electric vehicles extremely vulnerable to injuries in the event of a collision. Moreover, since there are no complete traffic regulations for electric bicycles, low-speed electric vehicles and other non-motor vehicles Violations of road traffic laws are punished. Therefore, it is not uncommon to drive electric bicycles to run red lights and go against the road, which seriously threatens the personal safety of the driver himself and others;

Embodiment
[0137] The map import unit imports the non-motor vehicle road route map of a certain area from the third-party database, and the intersection labeling unit marks each intersection in the road route map to form a intersection mark frame, and the Beidou positioning unit locates When the electric vehicle enters the mark frame of the intersection, the image acquisition unit starts to collect the traffic sign information of the intersection.
[0138]The image acquisition unit is located at the front end of the electric vehicle and collects traffic sign information towards the left front of the electric vehicle's travel direction. The included angle between the image acquisition direction of the image acquisition unit and the electric vehicle's travel direction is θ=30°, and the The angle between the image acquisition direction of the image acquisition unit and the horizontal plane is α=30°, and the acquisition angle of the image acquisition unit is constant;

The invention discloses an electric vehicle active braking system and method based on the Internet of Things, which relate to the technical field of active braking. The system comprises a route processing module for processing the driving route of the electric vehicle, a danger judgment module for judging whether dangers exist in continuous driving or not, a driving analysis module for analyzing and predicting the current driving track of the electric vehicle, a driving detection module for detecting the current driving environment of the electric vehicle in real time, a control module for intelligently controlling the electric vehicle, and an execution module for executing a control instruction issued by the control module. When the electric vehicle arrives at the intersection marking frame, the driving track of the electric vehicle can be analyzed, the following travel of the electric vehicle is predicted, and whether the electric vehicle needs to be automatically braked or not can be judged by combining the result of the traffic sign analyzed by the signal analysis unit.
Description
technical field [0001] The invention relates to the technical field of active braking, in particular to an active braking system and method based on the Internet of Things. Background technique [0002] Electric bicycles, electric motorcycles, and low-speed electric vehicles are non-motorized vehicles driven by electricity. Generally speaking, electric vehicles use batteries as energy sources, and convert electrical energy into mechanical energy through controllers, motors and other components. Vehicles whose speed is changed by controlling the magnitude of the current; [0003] Existing electric bicycles, electric motorcycles, and low-speed electric vehicles are not equipped with active braking systems during driving, resulting in traffic accidents such as rear-end collisions and collisions, and because electric bicycles, electric motorcycles, and low-speed electric vehicles are not equipped with The protective device makes electric bicycles, electric motorcycles, and low-...
