The MCU refers to a microcontroller (Microcontroller Unit) and is a single-chip microcomputer system integrated with a Central Processing Unit (CPU), a memory and various peripheral interfaces. Compared to computers, MCUs are simpler, more compact, and are commonly used in embedded systems.
The MCU generally has the following functions and roles:
(1) Control and process external devices: the MCU includes various peripheral interfaces such as a communication interface (serial port, SPI, I2C, etc.), analog input/output, timer, GPIO (general purpose input/output port), etc., and can communicate and control with external devices (e.g., sensors, actuators, displays, etc.).
(2) And (3) running a control program: the CPU built in the MCU can execute embedded software, including an operating system, application programs, drivers and the like. Various functions and algorithms can be implemented by programming and respond to the external environment.
(3) Data processing and storage: the MCU has integrated therein memories including flash memory (for storing program code), RAM (for storing data), etc. The method can process input data, store intermediate results and output result data.
(4) Real-time performance and low power consumption: MCUs are typically designed to have real-time response capability and low power consumption characteristics, and are suitable for application scenarios with high time requirements, limited resources, or long-time operation.
The above-mentioned OLED (Organic Light-Emitting Diode) is an Organic Light-Emitting Diode, and belongs to a new product on the mobile phone OLED. Unlike conventional LCD display modes, OLED display technology does not require a backlight, and uses a very thin organic material coating and a glass substrate (or flexible organic substrate), which emits light when a current is passed through them. Moreover, the OLED display screen can be made lighter and thinner, the visual angle is larger, and the power consumption can be remarkably saved.
The Deserializer (commonly known as an automotive circuit) is a digital circuit assembly for splitting an input signal line into a plurality of output signal lines. Which routes the incoming data signals to the corresponding output ports, mainly in accordance with the incoming control signals.
The deserializer typically has one input port and a plurality of output ports, where the signal on the input port is parsed into a binary coded format. By controlling the encoding of the input signal, the transmission of the data signal to a specific output port can be selected. The function of the deserializer is to de-encapsulate the input signal and direct it to the corresponding output port.
For example, a 4-1 deserializer has a 4-bit input port and 4 output ports. When the control input signal is 00, the input signal is routed onto the first output port; when the control input signal is 01, the input signal is routed onto the second output port, and so on. The switching command may be generated by manually triggering a button of the switching area, or may be automatically generated according to the driving state.
Step S200, according to the switching instruction, the MCU is utilized to acquire the current driving state and the current display mode of the assistant driving display screen;
the current driving state may include states other than driving, for example, a stationary state, a non-driving state, and the like.
Above-mentioned, the car machine central control system can obtain the current driving state that the switching instruction corresponds through MCU to and current display mode.
And step S300, switching the display mode of the assistant driving display screen according to the current driving state based on the current display mode.
When the current display modes are different and the current driving states are different, the transparent OLED screen and the electronic ink screen are overlapped in the display area of the co-driver, and the display modes in the display screen are switched according to the driving safety requirements.
According to the embodiment, the technology of superposing the transparent OLED screen on the electronic ink screen is adopted for the screen at the co-driving position, the switching instruction is automatically or actively triggered and generated under different driving states of the vehicle, and the different current display modes of the OLED display screen and the ink screen display screen are switched under the control of the MCU, so that the automatic or manual switching of the display screen by the vehicle according to different driving states is realized, the influence on eyesight caused by long-time watching of passengers of the co-driving can be avoided, the influence on the driver can be reduced, and the driving safety of the vehicle is improved.
Example 2:
referring to fig. 3, embodiment 2 of the present invention provides a vehicle-mounted secondary driving on-screen control method, based on embodiment 1 above, the step S300, based on the current display mode, of switching the display mode of the secondary driving display screen according to the current driving state, includes:
step S310, judging whether the current display mode is an ink screen mode;
step S320, if the current display mode is the ink screen mode, judging whether the current driving state is in driving;
the current display mode includes the ink screen mode and the OLED mode.
Step S330, if the current driving state is in driving, stopping the switching process and generating prompt information for prohibiting switching;
and step 340, if the current driving state is not in driving, judging that the current vehicle is in a non-driving state, and switching the display mode of the secondary driving display screen through the MCU.
In the display mode of the ink screen mode, different control logic is provided for switching the display mode of the screen according to different driving states.
The electronic ink screen should be used for display while the vehicle is running, and the OLED screen is set to be transparent for display, which solves the problem that the screen may interfere with the driver's vision when the driver views the right side rearview mirror. On the basis of the display of the ink screen, if a switching instruction is received when the driving state is in driving, the switching process should be stopped, switching is forbidden, and a prompt message is generated to prompt that switching is forbidden.
On the basis of the display of the ink screen, when the driver is driving, the switching process is stopped, and the interference of the light rays of the OLED display screen on the sight of the driver is avoided.
If the driving state is a stationary state of the vehicle, or a flameout, non-start, non-running state, a switch from the ink screen mode to the OLED mode may be made.
Further, referring to fig. 4, in step S340, the switching of the display mode of the secondary driving display screen through the MCU includes:
step S341, the MCU generates a switching signal and sends the switching signal to the secondary driving display screen through a vehicle central control system;
in step S342, after receiving the response information corresponding to the switching signal, the MCU controls the display mode of the secondary driving display screen to switch to the OLED mode through a switch, and outputs a color picture signal to the secondary driving display screen through the vehicle central control system.
When the display mode is switched, firstly, the MCU generates a switching signal, and the switching signal is sent to the secondary driving display screen through the vehicle central control system, so that the display mode is adjusted, and a black display signal is output; after the vehicle central control system transmits the black display signal, the MCU controls the signal change-over switch to output the output signal to the OLED display screen, and the vehicle central control system displays the signal of the color picture to the transparent OLED display screen to finish the change-over.
Further, step S310 further includes, after determining whether the current display mode is the ink screen mode:
step S350, if the current display mode is not the ink screen mode, determining that the current driving state is in driving when the current display mode is the OLED mode.
Step S360, if the current driving state is not in driving, judging that the current vehicle is in a non-driving state;
step S370, switching display modes of the auxiliary driving display screen through the MCU;
and step S380, if the current driving state is in driving, generating prompt information allowing switching, and executing the step S370 to switch the display mode of the auxiliary driving display screen through the MCU.
If the current display mode is not the ink screen mode, the current display mode is the OLED mode, that is, the OLED screen displays the output signal. At this time, the OLED display screen is set to display color signals.
However, if the current driving state is driving, the aforementioned "the problem that the screen would interfere with the driver's vision when the driver views the right side rearview mirror" does not occur. Therefore, switching is allowed under control of switching of the display mode.
In this embodiment, step S370 may be performed according to a switching instruction, that is, a step of switching the display mode of the secondary driving display screen through the MCU, regardless of the driving state during driving or non-driving.
Further, referring to fig. 5, in step S370, the switching of the display mode of the secondary driving display screen through the MCU includes:
step S371, the MCU generates a transparent display signal and sends the transparent display signal to the secondary driving display screen through a vehicle central control system;
step S372, after receiving the response information corresponding to the transparent display signal, the MCU controls the display mode of the secondary driving display screen to switch to the ink screen mode through a switch, and outputs a black-and-white picture signal to the secondary driving display screen through the vehicle central control system.
In the process of switching from the OLED mode to the ink screen mode, the MCU sends a transparent display signal to the vehicle central control system, then the vehicle central control system outputs the signal to the secondary driving display screen, the MCU controls the video signal change-over switch to output the signal to the secondary driving display screen, the MCU informs the vehicle central control system of the completion of the switching, and the vehicle central control system displays a black-and-white picture signal to the electronic ink screen of the secondary driving display screen.
Example 3:
referring to fig. 6, embodiment 3 of the present invention provides a vehicle-mounted secondary driving on-screen control method, based on embodiment 1 above, the vehicle-mounted secondary driving on-screen control method further includes:
step S400, the MCU acquires a brightness enhancement instruction;
step S500, the MCU acquires a current display mode and a current driving state;
