Problems solved by technology
Because the existing GPS radar voice warning device broadcasts this type of information to the car driver in the form of voice, because the content of the broadcast is too many, it causes a relatively noisy voice environment in the car, which easily causes the driver's voice fatigue, thereby ignoring Important safety information on the road ahead, leading to driving safety hazards

Embodiment Construction
[0017] The invention relates to a head-up display method of GPS radar road condition data information, such as figure 1 — Figure 4 As shown, it is characterized by:
[0018] ①. The host computer collects the road safety information to be displayed by GPS and radar respectively, including receiving satellite signals by the GPS antenna and transmitting them to the PCB main board, and then the main chip MCU on the PCB main board extracts the database in the memory, and commands the driver after calculation The display screen displays road information on the glass mirrored below;
[0019] ②. The information is displayed on the glass receiving display screen, and then the information is enlarged and zoomed out accordingly;
[0020] ③. Use direct or indirect mirror projection or laser projection to mirror the glass onto the car's front windshield to present a virtual image, and guide the reconstructed information map light to the driver's field of vision through the refraction pr...

A method for horizontally displaying global positioning system (GPS) radar road condition data information comprises the following steps: (1) a host collects the road safety information respectively displayed by a GPS and a radar, a GPS antenna receives satellite signals, the satellite signals are transferred to a printed circuit board (PCB) mainboard, a main chip micro control unit (MCU) on the PCB main board is used for extracting a database in a memory, and after operation, a display screen is driven through commands so as to display and mirror the road information on glass below; (2) the glass receives the display information of the display screen, and then the information is correspondingly zoomed in and zoomed out; and (3) direct or indirect mirror projection or laser projection is used to mirror the glass to an automobile front windshield, so that a virtual image is shown, and restructured information graph lights are guided to the visual field of a driver through a refraction principle of the automobile front windshield.
Description
technical field [0001] The invention relates to a head-up display method for GPS radar road condition data information, which uses mirror projection to directly or indirectly project road condition data collected by GPS and radar onto the front windshield of an automobile, and the driver obtains the information on the windshield in the head-up view. data for the purpose of improving driving safety. Background technique [0002] The GPS radar voice warning device has been widely used to provide the driver with road safety information ahead when driving a car, such as: speed limit data of the driving road, red light photography and speed measurement photography, etc. Because the existing GPS radar voice warning device broadcasts this type of information to the car driver in the form of voice, because the content of the broadcast is too many, it causes a relatively noisy voice environment in the car, which easily causes the driver's voice fatigue, thereby ignoring Important sa...
