[0036] The application provides a method for adaptive adjustment of HUD based on driving information. The HUD is a head-up display system which can project important driving information such as speed and navigation onto the windshield in front of the driver, so that the driver can see the important driving information such as speed and navigation without looking down or turning his head. The HUD device has a PGU module for generating images. The application adds an NPU module to the HUD device, which can be in communication connection with the PGU module.

[0037] Please refer to Figure 1 which is a flowchart of the method for adaptive adjustment of HUD based on driving information provided by the first embodiment of the application. The method for adaptive adjustment of HUD based on driving information comprises steps S101-S106.

[0038] In step S101, the NPU receives driving information in the driving process collected by the information collection device.

[0039] As Figure 2 shown, the information collection device 1 comprises an in-and-out camera 2, a geographic position data system 3 and a radar 4. The in-and-out camera 2 is used to shoot face data to obtain driver identity information and record the driving process. The geographic position data system is used to obtain the geographic position of the vehicle. The radar 4 is used to obtain information in front of the road. The NPU module comprises a collection unit for receiving driving information in the driving process collected by the information collection device.

[0040] For example, a vehicle is driving on a road section with many low-lying parts. The driver identity information and the fact that the driver is in long-distance driving and the driver is making a phone call are obtained by obtaining the driving process video data in the in-and-out camera 2. The vehicle is in Guangdong Province, Shenzhen City, Baoan District, Qianjin Road II, which is obtained by obtaining the vehicle geographic position data in the geographic position data system 3. The road in front of the vehicle has a construction section, which is obtained by obtaining the data in the radar 4.

[0041] In step S102, the NPU determines whether a warning situation occurs according to the driving information. The warning situation includes: when the vehicle is on a highway or in long-distance driving, the road or the driving behavior of the driver is abnormal; when the vehicle is not on a highway and is not in long-distance driving, the road and the driving behavior of the driver are abnormal. The road abnormality includes: road congestion, road construction, intersection in front of the road, road in front of the road can change lanes, traffic accident on the road. The abnormal driving behavior of the driver includes: the driver in the vehicle is smoking, drinking water, or driving for too long to cause driving fatigue.

[0042] For example, by obtaining the position data of the vehicle in the geographic position data system 3, it is determined that the vehicle is at 90 degrees latitude 40 degrees, and if a highway is built at this location, it can be determined that the current vehicle is on the highway; by obtaining the front road data in the radar 4, it is determined that the front road has obstacles, and by obtaining the video taken by the camera of the vehicle being driven, it is determined that the current driver has been driving for 8 hours and is in a long-distance driving state. It can be determined that a warning situation has occurred.

[0043] Step S103, when a warning situation occurs, the NPU generates a warning information and sends it to the PGU. The warning information is a signal generated by the NPU that can be received by the PGU, and the signal loads instruction information. When a warning signal occurs, the instruction information is to adjust the display brightness of the PGU to a certain brightness value. The brightness value is pre-set, and each driver has a corresponding high brightness value. The instruction information also includes displaying pre-set icons or text according to the abnormal behavior information of the driver by the PGU.

[0044] For example, there are obstacles in front of the driving section, and the radar obtains data information that there are obstacles in front. The NPU determines that a warning situation has occurred, and sends a warning information to the PGU, which has a high brightness value corresponding to the driver. In another example, by analyzing the data obtained from the camera, it is determined that the driver is answering the phone, and the NPU determines that a warning situation has occurred, and sends a warning information to the PGU, which displays a pre-set icon or "no call" text to warn the driver that the above driving behavior is dangerous.

[0045] Step S104, when a warning situation does not occur, the NPU sends the normal driving information to the PGU. The non-warning situation is that neither the road nor the driver's behavior is abnormal. The normal driving information is a signal generated by the NPU that can be received by the PGU, and the signal loads instruction information. When a warning situation does not occur, the vehicle is on a highway or in a long-distance driving process, the instruction information is to adjust the display brightness of the PGU to a pre-set brightness value; when a warning situation does not occur but the vehicle is not on a highway and is not in a long-distance driving process, the instruction information is to control the display brightness of the PGU to the default normal display brightness, which is pre-set and different for different drivers.

[0046] For example, Mr. Wang drives a vehicle on a highway, the road is flat and there are no obstacles, and Mr. Wang's driving behavior is not abnormal. The NPU determines that a warning situation has not occurred, and sends normal driving information to the PGU, which has a pre-set low brightness display value corresponding to Mr. Wang.

[0047] For example, Mr. Li drives a vehicle on the street, the street is flat, the flow is sparse and orderly, and Mr. Li's driving behavior is normal. The NPU determines that no early warning situation occurs, and sends normal driving information to the PGU, wherein the normal driving information has a pre-set default normal display brightness value corresponding to Mr. Li.

[0048] Step S105, when the PGU receives the early warning information, the PGU controls the display brightness to be high brightness. The early warning information has a value for increasing the brightness, and the PGU increases the display brightness to the value.

[0049] Step S106, when the PGU receives the normal driving information, the PGU controls the display brightness to be non-high brightness, including low brightness and default normal brightness. When the vehicle drives on a highway or is in long-distance driving, the normal driving information has a value for decreasing the brightness, and the PGU decreases the display brightness to the value, thereby reducing the influence of the additional picture on the driver, and also saving power consumption; when the vehicle drives on the street, the normal driving information has a value for the default normal display brightness, and the PGU adjusts the display brightness to the value of the default normal brightness.

[0050] Please refer to Figure 3 , Figure 3 A first sub-flow chart of a method for adaptively adjusting a HUD based on driving information is provided for the embodiments of the present application. Step S105 specifically includes steps S1051-S1055.

[0051] Step S1051, the NPU detects the identity information of the driver through an in-vehicle camera. The identity information of a plurality of drivers is pre-stored in the HUD device.

[0052] Step S1052, when the identity information has a matched default normal brightness, the NPU controls the PGU to display the low brightness, and the default normal brightness is pre-set by the user. The HUD device stores a default normal brightness value corresponding to each driver, and the PGU displays the brightness according to the value, for example, the brightness value range is 40 to 80, and the normal brightness value range is 55 to 65.

[0053] Step S1053, when the identity information does not have a matched default normal brightness, the NPU sends a default normal brightness setting instruction to the PGU.

[0054] For example, when the vehicle changes the driver, there is no corresponding default normal brightness, and the corresponding default brightness needs to be set.

[0055] Step S1054, the PGU prompts the driver to set the default normal brightness through the display interface. The display screen of the PGU displays the prompt information "please set the default brightness value".

[0056] Step S1055, the PGU controls the display brightness to be the default normal brightness.

[0057] The above embodiment provides a method for adaptively adjusting the HUD based on driving information, which comprises the following steps: Figure 4 As shown, first, driving information is acquired. Then, it is determined whether the current driving vehicle is on a highway section or for long-distance driving according to the driving information. If yes, the HUD is adjusted to a preset low brightness display. Then, it is determined whether the current road condition is abnormal or the driving behavior is abnormal. If yes, the HUD is adjusted to a high brightness display. If no, the low brightness display is continued. If the current driving vehicle is not on a highway section or for long-distance driving, the normal brightness is displayed. Then, it is determined whether the current road section is dangerous. If yes, the HUD is adjusted to a high brightness display. If no, the normal brightness is continued. The brightness of the HUD is automatically adjusted according to the acquired driving information, the display brightness is increased when dangerous road sections and abnormal driving behaviors are encountered, the driver is reminded to pay attention, and the driver is supervised to end the abnormal driving behavior, so that the driving process is safer.
