Description
Technical Field
The invention relates to a split type vehicle-mounted head-up display with GNSS and OBD-II.
Background
The existing vehicle head-up display (HUD) mainly has two modes for acquiring driving data.
The first method adopts a GNSS chip, obtains positioning data through navigation satellites such as a GPS and a Beidou, and indirectly obtains and calculates navigation information such as vehicle speed, altitude, time and the like. The advantages are that: the method is independent of the communication protocol of the automobile, and can be applied to any automobile. The disadvantages are that: 1. various data are indirectly calculated through positioning data, so that the acquired data have certain delay, the positioning data often have a drift phenomenon, the indirectly calculated data also have errors, and the precision is reduced; 2. the data can be acquired and displayed only at the position with the GNSS signal, and the speed of the automobile cannot be displayed at the positions of a tunnel, an underground parking lot and the like because the GNSS signal is very weak; recently, GNSS chips with inertial navigation function can solve some of the above problems, but the cost is very high, and once the GNSS chips are used, the cost of the product is greatly increased.
The second type utilizes the automobile OBD-II diagnosis interface, and the HUD is communicated with the automobile ECU through the interface to acquire and display automobile diagnosis data in real time. The advantages are that: 1. because the vehicle-mounted data acquisition system is in direct communication with the vehicle, the acquired data are the original vehicle data, and the real-time performance can be ensured; 2. the driving data can be acquired at any position as long as the driving data can be communicated with the automobile ECU without depending on other signals. The disadvantages are that: 1. because the protocols based on the OBD-II interface are various at present, and different automobile manufacturers can customize the protocols, although the standard protocols exist internationally, all automobiles are not compatible. The OBD-II interface is used for acquiring automobile data, analysis needs to be carried out according to protocols used by different automobiles, and various problems of the automobiles can be caused by the fact that the protocols which are not adapted are used for communicating with an automobile ECU. 2. The power supply of the OBD-II interface of the automobile is normal power, and the OBD-II interface cannot be powered on or powered off along with the start and stop of the automobile, so that the device for acquiring the automobile data by using the OBD-II interface needs to determine the power off or power on of the device after judging the start and stop of the automobile, the device keeps the power on state all the time, the power loss of an automobile storage battery in the parking state can be caused, and the automobile cannot be started next time.
