Description

TECHNICAL FIELD

[0001] The present application relates to the field of automotive electronic safety, in particular to an indirect vision system for single-ECU three-display vision processing and a vehicle. BACKGROUND

[0002] In the prior art, the ECU unit is the most common control unit, which is used to manage and control the specific functions or subsystems of the vehicle. Each system or subsystem usually has its own ECU, which is responsible for receiving sensor data, executing corresponding algorithms, and sending instructions to control the operation of the system. Generally, multiple ECUs are used to support the vision collection of electronic rearview mirrors, because in this case, the requirements for FPGA or SOC image processors are lower, and since multiple ECU units are used, each ECU corresponds to a camera. Since the running load of the ECU unit is low, it can be directly connected with the display, so as to actually reduce the probability of corresponding ECU unit downtime. Generally, the technical architecture is that the driver side Class II+IV, the co-driver side Class II+IV, and the Class V+VI systems are connected with the vehicle through independent ECUs. This solution has high cost, requires three power supplies and network connection nodes for the vehicle body, is the most difficult to implement, and has the lowest vehicle compatibility. There are fewer choices of chips that can meet the requirements of single-ECU supporting 3-way high-definition vision processing while meeting functional safety requirements, and the cost is high, and the development difficulty is great. With the iteration of technology, the existing ECU unit has gradually been able to meet the computing power required by the existing rearview mirror system. If only a single ECU unit is used for video processing, the architecture is as follows:

[0003] The driver side Class II+IV, the co-driver side Class II+IV, and the Class V+VI systems share one ECU, which is arranged in the Class II+IV monitor on the driver side. The video is pushed to the Class II+IV monitor on the co-driver side and the Class V+VI monitor on the co-driver side through two sets of chip addition and concatenation. The Class II+IV monitor on the driver side and the Class V+VI monitor on the driver side need corresponding deserializing boards to restore them into video signals for display. The cost is still relatively high. In addition, since the two monitors on the co-driver side are remote screens, the risk of functional safety failure is relatively high. Once the monitor on the co-driver side fails, the driver cannot slow down the vehicle and stop on the roadside of the co-driver side by observing the right side vision. SUMMARY

[0056] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0057] Example 1:

[0058] like Figure 1 As shown, this embodiment provides an indirect field of view system for field of view processing of a single ECU and three displays, which is deployed on a car and includes an ECU unit 1, a first display 2, a second display 3, and a third display 4;

[0059] The first display 2, the second display 3 and the third display 4 are connected to the same ECU unit 1; the ECU unit 1 outputs a field of view image signal and displays it on the first display 2 and / or the second display 3 and / or the third display 4;

[0060] The first display 2 and the third display 4 are used to display Class II and Class IV fields of view;

[0061] The second display 3 is used to display Class V and Class VI fields of view images;

[0062] The first display 2 and the second display 3 are arranged on the side of the co-pilot seat of the vehicle;

[0063] The third display 4 is arranged on the side of the driver seat of the vehicle;

[0064] The ECU unit 1 is arranged on the side of the co-pilot seat of the vehicle.

[0065] In the prior art, the ECU unit is the most common control unit for managing and controlling specific functions or subsystems of a vehicle. Each system or subsystem usually has its own ECU, which is responsible for receiving sensor data, executing corresponding algorithms, and sending instructions to control the operation of the system. Multiple ECUs are generally used to support the field of view collection of electronic rearview mirrors, because in this case, the requirements for FPGA or SOC image processors are lower, and because multiple ECU units are used, each ECU corresponds to a camera. Since the running load of the ECU unit is low, the probability of corresponding ECU unit downtime can actually be reduced. However, there are fewer choices of chips that can meet the functional safety requirements of a single ECU supporting three high-definition field of view processes, and the cost is high, and the development difficulty is great. The indirect field of view of the electronic rearview mirror is classified as: Class I: inner rear view; Class II and III: main outer rear view; Class IV: wide-angle outer view; Class V: blind-filling outer view; and Class VI: front view. In the prior art, the driver side Class II+IV, the co-pilot side Class II+IV, and the Class V+VI three systems share one ECU, which is arranged in the Class II+IV monitor on the driver side. Two sets of chip adders are used to push the video to the Class II+IV and Class V+VI monitors on the co-pilot side. The Class II+IV and Class V+VI monitors on the driver side need corresponding deserializers to restore them to video signals for display. The cost is still relatively high. In addition, since the two monitors on the co-pilot side are remote screens, the risk of functional safety failure is relatively high. Once the monitor on the co-pilot side fails, the driver cannot slow down and stop the vehicle on the roadside on the co-pilot side by observing the right side view.

[0066] Therefore, in this embodiment, to improve the overall safety of the system, the driver's cab on the side of the road is used for convenience when pulling over. The ECU unit is placed in the driving position of the car, which is close to the display on this side. Since the ECU unit is close to the display on this side, a direct connection can be made using an FPC cable. Compared with using a serial transmission method that requires multiple additional devices for data type conversion, the number of modules required is greatly reduced, so the probability of failure is relatively significantly reduced. Generally speaking, even if the display in the driving position far from the road fails, the display near the road can still be used to pull over, thereby ensuring the safety of the system. At the same time, since the ECU unit is located on the driving side of the car, while the second display in the traditional architecture is located on the far driving side, the safety factor is not good. Therefore, in order to improve the overall safety of the system, the second display is also placed on the driving side of the car, next to the first display and the ECU unit.

[0067] Please also note that this application only uses one ECU unit to support field of view video services, which does not mean that the entire vehicle has only one ECU unit. If only one ECU unit is used for field of view video processing, but the entire vehicle still has multiple ECU units, it still falls within the scope of protection of this application.

[0068] Specifically, in regions where right-hand driving is legal, such as in China, ECU unit 1 is located on the right side of the cab. In regions where left-hand driving is legal, such as in Japan, ECU unit 1 is located on the left side of the cab. For example, in left-hand drive countries like China, if the electronic rearview mirror on the driver's side (away from the roadside) fails while the driver is driving normally on the road, they should immediately pull over and await assistance. However, since ECU unit 1 is located on the passenger side, it can be directly connected using an FPC cable, significantly reducing the number of modules required. Therefore, there is no need to worry about both electronic rearview mirrors failing simultaneously, allowing the driver to pull over and await assistance using the passenger side mirror.

[0069] Preferably, the ECU unit 1 is connected to the power supply of the car on the passenger side of the car; the ECU unit 1 is connected to the CAN network of the car on the passenger side of the car.

[0070] At the same time, when the ECU unit is set to the co-pilot side, the car's power supply and CAN network are also connected on the co-pilot side. In this way, the entire system can only have the ECU on the co-pilot side connected to the car body, reducing the power supply and network node requirements of the car body.

[0071] Preferably, an ECU unit start button 9 is arranged on the third display 3 for starting the ECU unit 1. More specifically, since the third display 3 is connected to the ECU unit 1 through serial-parallel conversion, the driver can quickly start the ECU unit 1 through the ECU unit start button 9 arranged directly on the third display 3 at the side of the main driver's seat.

[0072] The embodiment improves the safety of the display at the side close to the emergency lane by arranging the ECU unit and the display screens of two different types of fields at the side close to the emergency lane of the driver's cabin of the vehicle, so that when the driver needs to stop by the roadside, the probability of failure of the electronic rearview mirror at the side close to the roadside is small, thereby improving the safety factor of the whole system, and at the same time, the use of a single ECU for field processing is realized without reducing the safety factor, thereby reducing the cost of the whole vehicle.

[0073] Embodiment 2:

[0074] As shown in Figures 1-5 The embodiment provides an indirect field system for field processing of a single-ECU three-display, which is based on embodiment 1, and preferably, the first display 2 and the ECU unit 1 are connected through FPC flexible wires; the second display 3 and the ECU unit 1 are connected through FPC flexible wires. The third display 4 and the ECU unit 1 are provided with a display serial chip 6 and a display deserial chip 5; the field image signal output by the ECU unit 1 is sent to the deserial chip after serial processing by the display serial chip 6; the field image signal received by the display deserial chip 5 is transmitted to the third display 4 through FPC flexible wires after deserial processing; the display serial chip 6 and the display deserial chip 5 are connected through fakra video lines.

[0075] In the embodiment, for the convenience of description, the left-hand drive area in China is still taken as an example. Since the ECU unit 1, the first display 2 and the second display 3 are arranged at the side of the co-driver, the relative distance is short, and therefore FPC flexible wires can be directly used for connection. On the one hand, since FPC flexible wires are parallel lines, the transmission rate is relatively high, and on the other hand, since serial chips are not needed for serial conversion, the cost of serial chips and deserial chips is saved. At the same time, since the third display 4 is located at the far end of the ECU unit 1, FPC flexible wires cannot be used, and only serial lines can be used for connection. More specifically, the ECU unit 1 converts the field image signal into a serial signal through a serial chip, and transmits the serial signal to the deserial chip at the side of the main driver through a serial line. The display deserial chip 5 deserializes the field image signal, converts it into a parallel signal, and transmits the parallel signal to the third display 4 at the side of the main driver for display.

[0076] In this embodiment, the display on the side close to the emergency lane is connected via an FPC parallel soft wire, and the display on the side away from the roadside is connected via a serial line, thereby reducing the number of required serial addition and deserialization chips and thus reducing costs.

[0077] Preferably, the first display 2, the second display 3, and the ECU unit 1 are integrated on the inner vehicle pillar on the passenger side of the vehicle; the first display and the second display share a brightness sensor. Furthermore, since the first display 2, the second display 3, and the ECU unit 1 are all located on the passenger side, they can be integrated into a single housing and hung on the inner vehicle pillar on the passenger side. Furthermore, since the two screens are located in the same location, they can share a brightness sensor to adjust their brightness, thus avoiding inconsistent brightness between the two screens due to the use of different brightness sensors, which could affect normal use in the dark.

[0078] Example 3:

[0079] like Figures 1-5 As shown, this embodiment provides an indirect field of view system for field of view processing with a single ECU and three displays. Based on Example 1, it preferably also includes: a camera module 7 for capturing field of view images; the ECU unit 1 is connected to the camera module 7 for receiving the field of view image signal output by the camera module 7 and outputting a displayable field of view image signal; the first display 2, the second display 3, and the third display 4 are used to receive and display the displayable field of view image signal. The camera module 7 specifically includes: a first camera for capturing Class II field of view images and Class IV field of view images on the co-pilot side; a second camera for capturing Class V field of view images and Class VI field of view images; and a third camera for Class II field of view images and Class IV field of view images on the driver's side.

[0080] In this embodiment, a single camera, designated Camera No. 1 (first camera), is used to capture images for both Class II and Class IV fields of view. A single camera, designated Camera No. 2 (second camera), is used to capture images for Class V and Class VI fields of view. The videos captured by these two cameras are transmitted to a single ECU unit, 1, in the video system. The ECU then pushes the captured images for Class II, Class IV, Class V, and Class VI fields of view to three displays, respectively.

[0081] Preferably, the ECU unit 1 comprises: a camera deserializing chip 8 connected with the first camera and the second camera respectively, for deserializing the field image signals output by the first camera and the second camera; an FPGA chip or an SOC chip connected with the camera deserializing chip 8, for converting the deserialized field image signals into displayable field image signals; an MCU chip connected with the FPGA chip or the SOC chip, for sending a control signal to control the opening and closing of the FPGA chip or the SOC chip.

[0082] In the embodiment, the camera deserializing chip 8 first converts the serial field image signals collected from the first camera and the second camera into parallel field image signals. Since the parallel data stream cannot be directly displayed, the deserializing chip converts the serial data stream into a parallel data stream and then adds an FPGA chip or an SOC chip to convert the serial data stream into displayable field image signals. The MCU chip controls the opening of the FPGA chip or the SOC chip, and the deserializing chip transmits the converted field image signals to the FPGA chip or the SOC chip on the PCB board which has been normally opened by the MCU chip.

[0083] The FPGA is a logic device that can be repeatedly programmed by engineers, and the body is a digital integrated circuit, which is a chip that can change the internal structure through programming. In the present application, the corresponding code for processing two-way field image signals is known to those skilled in the art, and no improvement of software program is involved.

[0084] The MCU chip refers to a microcontroller unit (MCU), also known as a single-chip microcomputer or a single-chip microprocessor. It is a chip-level computer that integrates the central processing unit's frequency and specifications, memory, counters, USB, A / D converter, UART, PLC, DMA, and even LCD driver circuit on a single chip for different application scenarios. Therefore, the MCU chip is a single-chip microcomputer chip.

[0085] Further preferably, the first camera and the second camera are connected with the camera deserializing chip 8 through fakra video lines, respectively outputting first GMSL field image signals and second GMLS field image signals;

[0086] The camera deserializing chip 8 is used for receiving the first GMSL field image signals and the second GMLS field image signals, and outputting first MIPI field image signals and second MIPI field image signals;

[0087] The FPGA chip or the SOC chip is configured to receive the first MIPI field of view image signal and the second MIPI field of view image signal, and output first LVDS field of view image signals and second LVDS field of view image signals to the display.

[0088] The camera deserializing chip 8 is configured to receive the first GMSL field of view image signal and the second GMSL field of view image signal, and output first MIPI field of view image signals and second MIPI field of view image signals.

[0089] The FPGA chip or the SOC chip is configured to receive the first MIPI field of view image signal and the second MIPI field of view image signal, and output first LVDS field of view image signals and second LVDS field of view image signals to the display.

[0090] LVDS (Low-Voltage Differential Signaling) is a signal transmission mode level standard proposed by National Semiconductor (NS, now TI) in 1994, which uses very low voltage swing high-speed differential transmission data, can realize point-to-point or one-to-many connection, has the advantages of low power consumption, low error rate, low crosstalk and low radiation, and has been widely used in serial high-speed data communication occasions, such as high-speed backplane, cable and board-to-board data transmission and clock distribution, and communication link within a single PCB.

[0091] Further preferably, the first display 2 and / or the third display 4 are connected with the FPGA chip or the SOC chip, and are configured to receive the first LVDS field of view image signal to display the type II field of view and the type IV field of view.

[0092] The second display 3 is connected with the FPGA chip or the SOC chip, and is configured to receive the second LVDS field of view image signal to display the type V field of view and the type VI field of view.

[0093] The above content can be converted into the following steps:

[0094] Step 1: The type II and type IV fields of view need to share one camera to obtain images, which is marked as camera No. 1.

[0095] Step 2: The camera No. 2 is needed to acquire images for the Class V and VI fields of view.

[0096] Step 3: The two images captured by the camera No. 1 and the camera No. 2 are needed to be transmitted to the deserializing chip on the PCB board in the form of GMLS signals through the fakra video line.

[0097] Step 4: The deserializing chip converts the GMLS signals into MIPI signals and transmits them to the FPGA chip or the SOC chip on the PCB board which has been normally started by the MCU.

[0098] Step 5: The FPGA chip or the SOC chip divides the two MIPI signals into two paths after processing. The first path of the Class II and Class IV images is connected to the Class II and Class IV display panels in the form of LVDS signals through the FPC flexible flat cable to display the Class II and Class IV fields of view; the second path of the Class V and Class VI images is also connected to the Class V and Class VI display panels in the form of LVDS signals through the FPC flexible flat cable to display the Class V and Class VI fields of view.

[0099] The embodiment combines the hardware of multiple ECU units into one ECU unit, processes the images acquired by the two cameras simultaneously, and then outputs them to the Class II and Class IV display panels and the Class V and Class VI display panels respectively, so as to achieve the effect of simultaneously displaying the Class II, Class IV, Class V and Class VI fields of view, reduce the number of hardware and the product cost.

[0100] Embodiment 4

[0101] As shown in Figures 1-5 , the embodiment provides an automobile which is provided with the single-ECU three-display field-of-view processing indirect field-of-view system according to any one of embodiments 1-3. The automobile is generally a large or medium-sized transport truck.

[0102] The embodiment achieves the following effects through the above-mentioned embodiments:

[0103] (1) The embodiment improves the safety of the display on the side close to the emergency lane by arranging the ECU unit and the display screens of two different types of fields of view on the side of the cab close to the emergency lane, so that when the driver needs to park by the roadside, the probability of failure of the electronic rearview mirror on the side close to the road is smaller, thereby improving the safety factor of the whole system, and at the same time, the use of a single ECU for field-of-view processing is realized without reducing the safety factor, thereby reducing the cost of the whole vehicle.

[0104] (2) by FPC parallel soft line connection through the display near the emergency lane on one side, away from the roadside on the side of the display through the serial line connection, reduces the number of required add and subtract serial chip, thereby reducing the cost, at the same time, because the power supply and CAN network of the car are also connected on the side of the co-driver, so the whole system can only have the ECU on the side of the co-driver connected with the vehicle body, reducing the requirements of the power supply and network node of the vehicle body;

[0105] (3) by merging multiple ECU unit hardware into one ECU unit, then processing the images obtained by the two cameras at the same time, and outputting them to the type II, type IV display and type V, type VI display respectively, achieving the effect of simultaneous display of type II, type IV, type V and type VI view, reducing the number of hardware and product cost.

[0106] Although the preferred embodiments of the present application have been described, those skilled in the art, once they know the basic creative concept, can make additional changes and modifications to these embodiments.
