GPS-based intelligent pre-warning system for hybrid power automobile

Abstract

The invention relates to a GPS-based intelligent pre-warning system for a hybrid power automobile. The functions of safety distance measurement, signal identification and warning in the running process of the automobile are achieved. The system structurally comprises a millimeter wave range radar, a GPS processor, a voice prompt system, an LCD, a temperature sensor, a humidity sensor, a radio receiving module and a storage module, wherein the millimeter wave radar is installed at the front end of the automobile, the GPS processor is responsible for calculating and comparing safety distance and controlling the millimeter wave radar, a voice warning device and the LCD to work by sending a signal, after the voice warning device receives the signal, a voice prompt is given to a driver, the current automobile speed and the distance between two automobiles are displayed by the LCD, input of the temperature sensor and input of the humidity sensor are used for correcting theoretical safety distance, parameters needed for calculation of the safety distance are stored in the storage module and can be called out by the processor, and the radio receiving module receives satellite signals for navigation.

Description

technical field [0001] The invention relates to a GPS-based intelligent early warning system for a hybrid electric vehicle, which realizes the functions of safe distance measurement, signal identification and alarm during the driving process of the vehicle. Background technique [0002] As one of the main means of transportation in new energy vehicles, hybrid electric vehicle has become the focus of people's more and more attention at the same time. When a hybrid vehicle is driving on the highway, because the distance between the two vehicles is too close, even if the correct braking method is adopted in an accidental situation, it is still impossible to avoid the collision of the two vehicles; in the case of heavy fog or dust, the visibility is relatively low In the bad weather, the driver cannot accurately estimate the safe distance between the two vehicles, which leads to the occurrence of traffic accidents. [0003] At present, research on collision avoidance systems at...
