Embodiment Construction

[0014] The GPS-based intelligent early warning device for electric vehicles is an extension of the existing GPS functions. Use GPS's existing vehicle speed measurement function, and integrate the program that calculates the vehicle speed into a theoretical safe distance, a distance display system between two vehicles, a program that compares the theoretical safe distance and the actual distance between two vehicles, and a voice prompt system.

[0015] The present invention will be described in detail below with reference to the accompanying drawings. As attached figure 1 As shown, the structure of the present invention includes: 1. Sensing part; 2. Signal processing part; 3. Temperature sensor; 4. Humidity sensor; 5. Radio receiving module; 6. GPS processor; 7. Storage unit; 8. Voice prompt system; 9. LCD display. The working principle of the system is attached figure 2 Shown: When the car is running, the driver presses the start button to initialize the system; the radio rece...

Abstract

The invention provides a GPS-based electric automobile safety distance intelligent warning device comprising a millimeter wave ranging radar, a GPS processor, a voice prompt system, an LCD, a temperature sensor, a humidity sensor, a radio receiving module, and a storage module. The millimeter wave radar is installed at the front end of an 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 receiving the signal, the voice warning device can prompt a driver with voice. The LCD displays the current automobile speed and distance between two automobiles. Input of the temperature sensor and input of the humidity sensor are used for correcting the theoretical safety distance. Parameters needed for calculation of the safety distance are stored in the storage module and can be called by the processor. The radio receiving module receives satellite signals and carries out navigation. By adopting the existing speed measuring function of the GPS, the structure is simplified, and the accuracy of measurement is improved.

Description

[0001] technical field [0002] The invention relates to a GPS-based intelligent early warning device for safe distance of an electric vehicle, which realizes the functions of measuring, judging and alarming the safe distance during driving of the vehicle. Background technique [0003] As the main means of transportation in new energy vehicles, electric vehicles have become the focus of more and more attention to their safety performance. When an electric car is driving on the highway, because the distance between the two cars 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 cars; In the weather, the driver cannot accurately estimate the safe distance between the two vehicles, which leads to the occurrence of traffic accidents. [0004] At present, research on collision avoidance systems at home and abroad is mainly divided into two categories: one is the safety distance measurem...
