The system is characterized in that a high-speed transceiver is connected with the high-speed CAN bus, a low-speed transceiver is connected with the low-speed CAN bus, the high-speed transceiver and the low-speed transceiver are connected with an information collecting module through wires, the information collecting module is connected with a controller through a wire, a vehicle-mounted radar information output end is connected with the controller through a wire, and the output end of the controller is connected with a speech module and a liquid crystal displayer through wires. The vehicle-mounted head-up display system solves the problems that display information of an existing vehicle-mounted head-up display system is single, display content is distributed on a whole display area and is not displayed in a classified mode and in different areas according to importance and features of the information, drivers need to distinguish the information needing to be watched, visions of the drivers are influenced, and visual fatigue of the drivers is easy to cause.
Description
Technical field
The invention belongs to on-vehicle information technology, relate in particular to a kind of vehicle-mounted head-up-display system and display method thereof.
Background technology
At present, auto meter has developed into electronic instrument from mechanical type instrument, but checking in meter information process, chaufeur still needs to bow and eye focus is adjusted on gauge panel from afar, after finishing watching meter information, come back again and eye focus is adjusted in road ahead from gauge panel, thereby produce the eliminating driving blind area time, the attention of this section of blind area time chaufeur forwardly on road, is not easy to cause traffic accident.Head-up-display system can be by some important information Projection Display of automobile to front windshield, realization is the information such as display automobile speed in Driver Vision zone of reasonableness, reduce pilot's line of vision and remove the time of driving direction, chaufeur does not need to bow and checks instrument, thereby shortens the blind area time of chaufeur to forward visibility.Therefore HUD system checks because bowing that to reducing gauge panel increases caused road traffic accident of vision dead zone time and has important contribution.Had at present part vehicle to be equipped with head-up-display system, but general head-up-display system mainly be take the real-time running informations such as the demonstration speed of a motor vehicle, engine speed as main, Presentation Function is comparatively single.On the other hand, the displaying contents of existing head-up-display system is covered with whole viewing area, according to the importance of information and feature, classify and show and subregion demonstration, need chaufeur oneself to go to differentiate the required information of seeing, so not only affect pilot's line of vision, also easily cause Driver Vision tired.Along with the raising of people to traveling comfort and safety, the information that head-up-display system will show can be more, if do not classified, subregion shows, not only can not improve the recognizing property of knowledge of driving information, can affect on the contrary chaufeur and drive.
Summary of the invention
The technical problem to be solved in the present invention: a kind of vehicle-mounted head-up-display system and display method thereof are provided, to solve existing vehicle-mounted head-up-display system, show that information is single, displaying contents is covered with whole viewing area, according to the importance of information and feature, classify and show and subregion demonstration, need chaufeur oneself to go to differentiate the required information of seeing, affect pilot's line of vision, easily cause the problems such as Driver Vision fatigue.
Technical solution of the present invention:
A kind of vehicle-mounted head-up-display system, it comprises automobile CAN-bus, automobile CAN-bus comprises high-speed CAN bus and low speed CAN bus, high-speed transceiver is connected with high-speed CAN bus, low speed transceiver is connected with low speed CAN bus, and high-speed transceiver is connected with information acquisition module wire respectively with low speed transceiver, and information acquisition module is connected with controller wire, trailer-mounted radar information output is connected with controller wire, and controller output end is connected with Liquid Crystal Display wire with voice module.
High-speed transceiver is MC33989 module, and low speed transceiver is MC33388 module.
Controller is MC9S12XS128 module.
Photosensor is installed in car, and the signal output part of photosensor is connected with controller wire.
Windshield left hand display area is used for show navigator information, reverse image and driving information and failure message, and this region is positioned at the dead ahead of pilot's line of vision.
Windshield right hand display area shows the speed of a motor vehicle, real-time fuel consumption, cooling-liquid temperature and engine speed.
Beneficial effect of the present invention:
The present invention is by the real time data information in integrated high low speed transceiver Real-time Collection automobile high-speed CAN bus and low speed CAN bus, by data acquisition module, deliver to controller, by controller, driving Liquid Crystal Display to show is projected on shield glass for chaufeur real time inspection, the shown information exchange of the present invention is crossed subregion and is shown, be divided into left and right sides viewing area, by gathering the information in CAN bus, make information A wide selection of colours and designs, solved the information Single-issue of existing vehicle-mounted head-up-display system, by being classified, dissimilar information shows or prompting, and the method that adopts subregion to show, this device is put in to the position that chaufeur dead ahead takes over, in the process of moving, the displaying contents of right side area is located substantially in the right-hand lane of traveling lane, interference to dead ahead, track, chaufeur place traffic information is very little, thereby can improve knowledge the recognizing property of chaufeur to information, improve driving safety, the invention solves existing vehicle-mounted head-up-display system and show that information is single, displaying contents is covered with whole viewing area, according to the importance of information and feature, classify and show and subregion demonstration, need chaufeur oneself to go to differentiate the required information of seeing, affect pilot's line of vision, easily cause the problems such as Driver Vision fatigue.
