Abstract
The utility model discloses an automobile instrument display device which comprises a control system and a synthetic display panel connected with the control system, the control system comprises a power module and a central processing unit (CPU) controller, and the CPU controller is connected with a controller area network (CAN) controller, a synchronous dynamic random access memory (SDRAM) and a flash. The CAN controller is connected with a CAN transceiver, and the CAN transceiver is connected with a CAN bus. The synthetic display panel is composed of a liquid crystal display (LCD) display area and a light-emitting diode (LED) area, and an LED comprises a left side LED display area and a right side LED display area. According to the automobile instrument display device, stability of instructions of an automobile instrument is guaranteed, timeliness of response of the instrument is guaranteed when a state of an automobile changes, the middle portion utilizes the LED to display an speed and rotating speed area needing fast refresh, and the periphery utilizes the LED to reduce cost of an instrument panel.
Description
Technical field
The utility model relates to the auto meter field.
Background technology
Progress along with science and technology, the performance of automobile is greatly improved, although traditional mechanical automobile instrument has cheap, the advantage of dependable performance, but require for auto meter precision and speed of response at high-end automobile more and more higher, instrument pattern individual demand more and more stronger today, orthodox car instrument response speed is slow, pointing accuracy is poor, and the shortcoming of poor stability is more and more obvious, can't catch up with gradually the development need of vehicle electronics.Improving precision and speed of response and the stability of auto meter, is the problem of the nowadays required solution of auto meter.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provide a kind of LCD of utilization and LED refresh rate fast, the advantage that stability is high, in real time the picture of LCD is refreshed by background program, and utilize LED to show driving states, and it is slow to solve orthodox car instrument response speed, and pointing accuracy is poor, poor stability, the shortcoming of lacking individuality.
The utility model is achieved through the following technical solutions:
A kind of vehicle instrument display device, comprise control system and the summary display panel that is connected with control system, described control system comprises power module and cpu controller, described cpu controller is connected with CAN controller, SDRAM, flash respectively, described CAN controller is connected with the CAN transceiver, and the CAN transceiver is connected with the CAN bus; Described summary display panel is made of LCD display space and LED display space, and described LED comprises LED display space, left side and LED display space, right side.
Described cpu controller is connected with serial ports.
Described cpu controller is connected with ethernet controller.
Described cpu controller is connected with other expansion mouth.
The utility model has the advantages that: the stability that 1, guarantees the auto meter indication; The real-time of instrument response when 2, guaranteeing the vehicle condition variation; 3, centre portion utilizes speed and the rotary speed area that LCD shows needs fast refresh, utilizes LED to reduce the cost of gauge panel all around.
Description of drawings
Fig. 1 is constructional drawing of the present utility model;
Fig. 2 is control principle block diagram of the present utility model.
The specific embodiment
Embodiment: vehicle instrument display device as shown in the figure, comprise control system and the summary display panel 2 that is connected with control system, described control system comprises power module and cpu controller, described cpu controller is connected with CAN controller, SDRAM, flash respectively, described CAN controller is connected with the CAN transceiver, and the CAN transceiver is connected with the CAN bus; Described summary display panel 2 is made of LCD display space 3 and LED display space, and described LED comprises LED display space 1, left side and LED display space, right side 4.Described cpu controller is connected with serial ports.Described cpu controller is connected with ethernet controller.Described cpu controller is connected with other expansion mouth.
Above-mentioned summary display panel is divided into LCD display space 3 and LED display space 1,4.LCD display space 3 is mainly used in the speed per hour that shows that speed of response is had relatively high expectations, and rotating speed and other require the content of Indivitual display, such as demonstration of the signals such as voltage, electric current, electric weight, simulation speed per hour etc.Lamp in the LED display space 1,4 is mainly used in indicating some car body running state or warning messages.This implementation method not only is conducive to reduce design cost, has also made things convenient for debugging.
Middle LCD display space 3 can be shown by following content:
Liquid crystal display shows electric weight, speed meter, rotating speed amount from left to right successively when driving.
Electric weight, rotating speed amount are by the expression that combines with real time data of column figure.Utilize color to simulate current value, give the car owner with visual impression; Above the column figure, demonstrate real time data, make things convenient for the car owner to grasp more accurately data.
Speed meter is made the form of traditional indicator, also is to offer car owner's visual impression and data accurately from indicator in conjunction with real time data two aspects.
The about square region in speed meter bottom shows the information that the car owner is concerned about as the car running computer display space in the situation that the car owner needs.
Lamp district in the LED display space 1,4 can be following setting:
The symmetrical two parts in status lamp zone form;
9 positions have been reserved in left zone, can satisfy the car owner to the demonstration demand of travel condition of vehicle and vehicle trouble caution;
5 positions are reserved in right zone, can replenish the car owner to the demonstration demand of vehicle-state and vehicle trouble caution.
About the zone when the indicator lamp not enabled, the dark-coloured decorative pattern on the display panel.After indicator lamp was enabled, because the contrast effect of light and environment, dark-coloured decorative pattern was also not obvious, can not upset car owner's sight line.
