Description
Technical Field
The utility model belongs to the technical field of electronic rearview mirrors, and relates to a vehicle body structure capable of testing the time delay of an electronic rearview mirror picture.
Background
The delay problem of the electronic rear view mirror may cause a delay in the response time of the driver. Compared with the traditional rearview mirror, the electronic rearview mirror has a certain delay in transmitting images, which is caused by processing time among components such as an image sensor, a processor, a display and the like. When the driver observes an image in the electronic rear view mirror, the delay causes it to feel a delay from the actual situation, possibly affecting the reaction speed of the driver. Particularly in the case of a need for a quick change of view, such as overtaking, lane changing or avoidance of obstacles, the delay may lead to errors in the judgment and countermeasures of the driver, increasing the potential safety risk.
Second, the delay problem of the electronic rear view mirror may cause visual fatigue of the driver. Due to the delay, the driver needs additional attention and concentration to make adjustments and decisions while viewing the image in the electronic rear view mirror. Prolonged use may lead to eye strain and distraction, which in turn affects the driver's attention and response. Such visual fatigue may increase the misjudgment of the driver and the risk of accident.
Furthermore, the problem of delay in the electronic rear view mirror may also lead to inaccurate perception of the surrounding environment by the driver. Due to the delay, the image in the electronic rearview mirror may have a certain difference from the actual situation. This may lead to inaccurate driver understanding of the location, speed, and distance of other surrounding vehicles, pedestrians, or obstacles, thereby affecting the driver's judgment and decision making ability. Especially in complex traffic environments or high-speed driving, the delay may cause the visual perception of the driver to be inconsistent with the actual situation, and the risk of accidents is increased.
Finally, the delay problem of the electronic rearview mirror may affect the observation and recognition of the image details by the driver. Due to the time delay, the image in the electronic rearview mirror may appear blurred or jittered, so that the driver has difficulty in accurately observing and identifying details in the image. This may affect the driver's judgment and understanding of important information such as other vehicles, traffic signals, or road conditions, and thus the driving decision and driving safety. In order to improve the accuracy of the test, a further improvement of the test method is needed, so that a vehicle body structure capable of testing the time delay of the electronic rearview mirror is needed in unit of present.
