DESCRIPTION OF THE PREFERRED EMBODIMENTS

A vehicle vision system and/or driver assist system and/or object detection system and/or alert system operates to capture images exterior of the vehicle and may process the captured image data to display images and to detect objects at or near the vehicle and in the predicted path of the vehicle, such as to assist a driver of the vehicle in maneuvering the vehicle in a rearward direction. The vision system includes an image processor or image processing system that is operable to receive image data from one or more cameras and provide an output to a display device for displaying images representative of the captured image data. Optionally, the vision system may provide display, such as a rearview display or a top down or bird's eye or surround view display or the like.

Referring now to the drawings and the illustrative embodiments depicted therein, a vehicle 10 includes an imaging system or vision system 12 that includes at least one exterior facing imaging sensor or camera, such as a rearward facing imaging sensor or camera 14a (and the system may optionally include multiple exterior facing imaging sensors or cameras, such as a forward facing camera 14b at the front (or at the windshield) of the vehicle, and a sideward/rearward facing camera 14c, 14d at respective sides of the vehicle), which captures images exterior of the vehicle, with the camera having a lens for focusing images at or onto an imaging array or imaging plane or imager of the camera (FIG. 1). Optionally, a forward viewing camera may be disposed at the windshield of the vehicle and view through the windshield and forward of the vehicle, such as for a machine vision system (such as for traffic sign recognition, headlamp control, pedestrian detection, collision avoidance, lane marker detection and/or the like). The vision system 12 includes a control or electronic control unit (ECU) or processor 18 that is operable to process image data captured by the camera or cameras and may detect objects or the like and/or provide displayed images at a display device 16 for viewing by the driver of the vehicle (although shown in FIG. 1 as being part of or incorporated in or at an interior rearview mirror assembly 20 of the vehicle, the control and/or the display device may be disposed elsewhere at or in the vehicle). The data transfer or signal communication from the camera to the ECU may comprise any suitable data or communication link, such as a vehicle network bus or the like of the equipped vehicle.

FIG. 2 shows a common implementation block diagram of a digital camera with Low Voltage Differential Signaling (LVDS) signal output in a vehicle. This shows a standard implementation or block diagram of Digital (LVDS) Camera in ADAS. The camera (1) creates an image of the environment, and outputs it in LVDS (2) electrical signal format. The LVDS is received by one and only receiver, such as Vehicle Head-unit (3) for display. Due to the nature of an LVDS signal, and underlying encoding schemes employed, the LVDS signal cannot be simply “Y” connected for consumption of 2 or more receivers. Thus there is a need of a device or method to “repeat” the LVDS signal for consumption of multiple receivers.

FIG. 3 shows an LVDS splitter (4) as used in an example vehicle application, such as a system with three or four receivers. The camera (1) captures image data representative of an image of the environment, and outputs it in LVDS (2) electrical signal format. The LVDS is received by an LVDS Splitter/Repeater (4). The LVDS Repeater outputs the image to three receivers in this example—a head-unit (5), a first electronic control unit or ECU1 (6) and a second electronic control unit or ECU2 (7).

As shown in FIG. 4, an embodiment or internal block diagram of the proposed LVDS Splitter (4) includes an LVDS input (34) and three LVDS outputs (45, 46, 47). The LVDS signal is received from the camera or LVDS source via connector (34), and provided to a complementary de-Serializer (35). In Automotive LVDS signals, the Source Serializer and Receiving De-Serializer should be complementary or from the same family, so the encoding, decoding and encryption protocols match. The De-Serializer transmits signals to a field-programmable gate array or FPGA (37). These signals may be in MIPI (36) format as shown in FIG. 4, or they may be Parallel, depending on type of de-Serializer used.

The FPGA (37) performs the repeating of signals function and outputs the same data to multiple MIPI (Mobile Industry Processor Interface) buses. In the example embodiment of FIG. 4, the FPGA performs a 1:3 repeat function, and outputs data to three busses: (38), (39), (40), which are then encoded into LVDS signals by Serializer1 (42), Serializer2 (43), Serialzer3 (44), respectively. The repeated LVDS data is output on 3 connectors (45), (46), (47).

Optionally, the Automotive LVDS bus may also have Power-Over-Coax (PoC) Capability. If such a feature is in use in the vehicle LVDS bus, the proposed repeater design can make full use of such PoC. The design is capable to use this power for the repeater itself, and the connected remote camera on connector (34). This PoC utilization is described below.

As shown in FIG. 4, the diode D1 routes PoC voltage Vpoc1 to Vpoc, thus if the receiver connected on (45) has a PoC source capable to power the repeater and camera, Vpoc1 can source the desired current. The diode D2 routes PoC voltage Vpoc2 to Vpoc, thus if the receiver connected on (46) has a PoC source capable to power the repeater and camera, Vpoc2 can source the desired current. Likewise, the diode D3 routes PoC voltage Vpoc3 to Vpoc, thus if the receiver connected on (47) has a PoC source capable to power the repeater and camera, Vpoc3 can source the desired current. Moreover, such a configuration allows for current superposition from multiple PoC sources connected to either (45), (46), (47) in any combination. This is useful if one PoC source receiver does not have sufficient current capability to drive the whole system (e.g., camera and repeater).

If No PoC source is present, or PoC Source(s) do not have enough current capability to driver the camera and repeater unit, the vehicle battery or ignition power shall supply to connector (31). The primary power supply (32) shall be set to desired PoC voltage so the camera connected to (34) can be sourced with PoC.

The Microcontroller (41) is present to initialize all the de-serializers (35) and serializers (42), (43), (44) on the board. It may be useful to bring any intelligence or control needed for the board in future. The I2C bus is also connected to microcontroller (41) and FPGA (37) for control or intelligent software behavior needed to switch ON/OFF various MIPI busses. The system may also control the devices on the I2C bus such that only one of the LVDS receivers (not illustrated here) can send I2C messages through LVDS back channel.

Optionally, and with reference to FIG. 5, another embodiment is shown using discrete off-the-shelf LVDS repeaters. However, since those off-the-shelf ICs cannot be connected to the vehicle LVDS bus on (34), (45), (46), (47), the block diagram will remain almost the same as FIG. 4, except with the FPGA (37) replaced by off-the-shelf LVDS repeater ICs (48).

The vision system and/or camera(s) may utilize aspects of the vision systems and cameras described in U.S. Publication No. US-2017-0223306, which his hereby incorporated herein by reference in its entirety.

Nos. 7,855,755; 7,720,580 and/or 7,038,577, which are hereby incorporated herein by reference in their entireties), and may analyze image data to detect vehicles and/or other objects. Responsive to such image processing, and when an object or other vehicle is detected, the system may generate an alert to the driver of the vehicle and/or may generate an overlay at the displayed image to highlight or enhance display of the detected object or vehicle, in order to enhance the driver's awareness of the detected object or vehicle or hazardous condition during a driving maneuver of the equipped vehicle.

The vehicle may include any type of sensor or sensors, such as imaging sensors or radar sensors or lidar sensors or ladar sensors or ultrasonic sensors or the like. The imaging sensor or camera may capture image data for image processing and may comprise any suitable camera or sensing device, such as, for example, a two dimensional array of a plurality of photosensor elements arranged in at least 640 columns and 480 rows (at least a 640×480 imaging array, such as a megapixel imaging array or the like), with a respective lens focusing images onto respective portions of the array. The photosensor array may comprise a plurality of photosensor elements arranged in a photosensor array having rows and columns. Preferably, the imaging array has at least 300,000 photosensor elements or pixels, more preferably at least 500,000 photosensor elements or pixels and more preferably at least 1 million photosensor elements or pixels. The imaging array may capture color image data, such as via spectral filtering at the array, such as via an RGB (red, green and blue) filter or via a red/red complement filter or such as via an RCC (red, clear, clear) filter or the like. The logic and control circuit of the imaging sensor may function in any known manner, and the image processing and algorithmic processing may comprise any suitable means for processing the images and/or image data.
