[0019] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.
[0020] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied to power-assisted bicycles.
[0021] According to research, most of the existing power-assisted bicycle HUD systems rely on installing an independent HUD projection optical module on the windshield, and realize information display through the synergy with laminated glass. Although this design ensures the forward-looking and readability of information display to a certain extent, the viewing angles vary significantly due to the diversity of the body shape, height and riding posture of the power-assisted bicycle drivers. This inconsistency in viewing angles makes it difficult for the HUD system to ensure clear and unobstructed display of information in different body positions. Especially during riding, with the fine-tuning of body posture or bumpy road conditions, the rider may encounter blocked vision or information display deviation, making it difficult to continuously and accurately obtain vehicle status information and key data of the surrounding environment. In addition, the limitations of display content and the differences in viewing angles jointly restrict the rider's ability to fully control driving safety. In a complex and changing traffic environment, the immediate and accurate acquisition of information is the key to ensuring riding safety. However, these limitations of the current power-assisted bicycle HUD technology may cause riders to miss important information at critical moments, such as emergency road condition prompts, potential obstacle warnings, etc., thereby increasing driving risks.
[0022] Based on this, an embodiment of the present application provides an auxiliary driving device and method for a power-assisted bicycle, aiming to overcome at least one of the above-mentioned defects.

[0033] The ambient light sensor is arranged at the edge area of the transparent glass and is used to connect with the vehicle-mounted domain controller to send the detected ambient light intensity signal to the vehicle-mounted domain controller so that the vehicle-mounted domain controller controls the brightness of the projection of the projection module 102 according to the ambient light intensity signal.
