Problems solved by technology

However, the shortcomings of this type of HUD are also particularly obvious, such as the inability to automatically sense light, obtain the degree of ambient light and darkness, the imaging film (curtain) has a strong grainy feel, and the contrast and brightness are generally low, which is more obvious under strong light.
This type of HUD cannot be turned on when the vehicle's engine is started, nor can it be turned off when the engine is turned off
When the temperature is too high, the projection imaging unit cannot be turned off; this type of HUD cannot directly reply to WeChat by voice, and cannot log in to the user’s WeChat through the QR code generated in the mobile phone
This type of HUD does not have a remote control, and all operations can only be performed through gesture recognition or voice recognition

Abstract

The invention discloses an intelligent projection head-up display HUD navigation, which includes a main control CPU, an auxiliary control CPU, a digital projection display module, and a light sensing device; the main control CPU is connected to the auxiliary control CPU and the digital projection display module respectively; the light The sensing device and the digital projection display module are respectively connected to the auxiliary control CPU; the light sensing device obtains the ambient light intensity value, converts it into a 16-bit value, and transmits it to the main control CPU through the I2C serial port. The auxiliary control CPU reads the environment through the I2C serial port. Light intensity value. The intelligent projection head-up display HUD navigation of the present invention can automatically obtain the light and dark degree of the surrounding environment, and adjust the display brightness of the HUD according to the light and dark degree of the environment; the overall design is also more reasonable than the existing technology, improving the comfort of the user experience. Spend.

Description

technical field [0001] The invention relates to the field of vehicle equipment, in particular to an intelligent projection type head-up display (HUD) navigation. Background technique [0002] HUD stands for Head Up Display, meaning head-up display, which refers to projecting the content to be displayed on the windshield to form a virtual image outside the windshield. This technology first appeared on fighter jets, and the purpose is to keep the fighter pilot's sight directly in front of the plane. Since the 1990s, HUD has been gradually transformed into civilian vehicles. Its meaning is similar to the HUD of fighter jets, that is, to keep the driver's line of sight straight ahead and avoid accidents caused by the driver looking elsewhere. [0003] In recent years, based on the optical principle of traditional pre-installation HUD, HUD based on DLP digital projection has appeared in the aftermarket. This kind of HUD has the characteristics of small size, flexibility, multipl...
