Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples. It is to be understood that the embodiments described are some, but not all embodiments of the invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting. All other embodiments, which can be derived from the description of the embodiments of the present invention by a person skilled in the art, are within the scope of the present invention.
In the existing vehicle, a sensor and a control chip are generally connected in a single-point mode to realize communication, control and feedback between the control chip and the sensor. That is, each sensor is connected to the control chip. Since each sensor needs to be connected with the control chip, the control chip needs to separately control each sensor. For example, the control chip is connected to 6 sensors, and needs to send control commands to the sensors to perform management control of the sensors. In addition, the single-point connection mode of the sensor and the control chip is highly dependent on the arrangement condition of the control chip. If the sensor parameters are changed, the control chip needs to be modified correspondingly, and the redesign and modification of the control chip needs to be customized and developed by a control chip supplier, so that the development cost is high and the production cycle is influenced. For example, after the model of the sensor is changed, an interface connected with the sensor on the control chip needs to be modified, so that a control chip supplier needs to perform matching customization development, on one hand, the cost of the control chip supplier for matching customization development is very high, and on the other hand, after the customization development, field debugging is needed, so that the production rhythm of a production line is influenced.
In view of the above drawbacks of the prior art, an embodiment of the present disclosure provides a vehicle control system, and fig. 1 is a schematic structural diagram of a vehicle control system provided by an embodiment of the present disclosure, and as shown in fig. 1, the vehicle control system provided by an embodiment of the present disclosure includes at least one sensor 11, a data exchange chip 12, and a control chip 13. The data exchange chips 12 are in communication connection with the sensors 11. The data exchange chip 12 is communicatively connected to the control chip 13. The data exchange chip 12 is used for receiving the data collected by the sensor 11 and sending the data to the control chip 13, and sending a control instruction of the control chip 13 to the sensor 11. It should be noted that, because the vehicle requirements are different, the embodiment of the present invention does not limit the number of the connection sensors, and in fig. 1, 6 sensors 11 are exemplarily provided.
The embodiment of the utility model provides an in 11 sensors are used for gathering the vehicle outside, in the vehicle relevant information or vehicle relevant parameter. The embodiment of the utility model provides a do not limit to the type of sensor. The data exchange chip 12 is in communication connection with each sensor 11, so that the data exchange chip 12 can receive the collected data of each sensor 11. Since the data exchange chip 12 is also connected to the control chip 13 in a communication manner, the data exchange chip 12 can transmit the data collected by each sensor 11 to the control chip 13. The control chip 13 can transmit control commands for controlling the sensors to the sensors 11 through the data exchange chip 12, thereby realizing communication, control and feedback between the control chip 13 and the sensors 11.
The data conversion chip 12 in the embodiment of the present disclosure may perform centralized platform management on the collected data of each sensor 11, and the data conversion chip 12 sends the collected data of each sensor 11 to the control chip 13 in a unified manner, and sends the control instructions sent by the control chip 13 to each sensor 11 respectively, so that the management is more efficient. Taking the vehicle control system including 6 sensors 11 as an example, in the prior art, in a manner that each sensor is connected to the control chip at a single point, the control chip 13 needs to send a control command to each of the 6 sensors 11. In the embodiment of the present disclosure, since the data conversion chip 12 is provided, centralized platformization management can be implemented, the control chip 13 can only send one control instruction for controlling the 6 sensors 11 to the data conversion chip 12, and the data conversion chip 12 controls the 6 sensors according to the instruction of the control chip 13.
Because each sensor 11 is in communication connection with the control chip 13 through the data conversion chip 12, if a sensor of a different model is replaced or a sensor parameter is changed, the communication interface of the control chip 13 does not need to be modified, and only the data conversion chip 12 needs to be modified correspondingly. Because the internal algorithm or program of the control chip is modified, the algorithm or program relates to the bottom layer algorithm of the control chip, and other components communicating with the control chip or parts inside the control chip may be affected, therefore, the sensor 11 is set in the embodiment of the present disclosure to be in direct communication connection with the control chip 13 through the data exchange chip 12, if the sensor parameters are changed, only the corresponding modification configuration needs to be performed on the data exchange chip, the design of the control chip does not need to be changed, and the degree of dependence on the control chip is reduced. The data conversion chip has the function of a communication bridge between the sensor and the control chip, so that the data conversion chip is relatively easy to modify to adapt to the change of the sensor parameters, and only basic configuration is needed.
In some embodiments, the data exchange chip and the control chip are connected based on time-sensitive network communication. Because the data exchange chip needs to send the acquired data of each sensor to the control chip, in order to ensure that the data exchange chip has a larger bandwidth, the embodiment of the disclosure sets the time-sensitive network-based communication connection between the data exchange chip and the control chip. Because a plurality of sensors share the bandwidth, when the data flow is large, data streams sent by different sensors overlap in time, and conflict occurs, so that the data transmission delay has uncertainty. In order to enable communication between each sensor and the control chip to have more stable time attribute, the data exchange chip and the control chip are connected based on time-sensitive network communication. The time sensitive network is composed of a series of protocol standards, including the standards of clock synchronization, data scheduling and network configuration, thereby ensuring the requirements of low time delay, high reliability and the like of the network.
In some embodiments, the data exchange chip and the sensor communicate based on a serial Link GMSL protocol or a flat panel display Link FPD Link protocol. GMSL (Gigabit Multimedia Serial Links) is a Serial transmission interface standard for vehicles, supports coaxial cable transmission, supports POC power supply for coaxial cables, and is applicable to transmission of video, audio, and control signals. FPD Link (Flat Panel Display Link) is a technology for high bandwidth data point-to-point transmission, which can transmit uncompressed images, and can support HDMI, MIPI DSI input, LVDS/MIPI DSI output, and the like.
In some embodiments, as shown in fig. 2, the sensor 11 is communicatively coupled to the data exchange chip 12 via the serializer 14; the data exchange chip 12 is communicatively connected to the control chip 13 via a deserializer 15. The sensor 11 is connected with the data exchange chip 12 through the serializer 14, and the data exchange chip 12 is connected with the control chip 13 through the deserializer 15 in a communication mode. The serializer 14 is configured to perform serialization processing on the acquired data of the sensor 11 to convert the data into a low-voltage serial signal, and then transmit the low-voltage serial signal to the data conversion chip 12. The data conversion chip 12 transmits the low voltage serial signal to the deserializer 15 connected to the control chip 13, and the deserializer 15 converts the low voltage serial signal into a parallel signal and transmits the parallel signal to the control chip 13.
In some embodiments, the sensor comprises at least one of a camera, a radar, a temperature sensor, a pressure sensor, a speed sensor, an angle sensor, a gas sensor. The sensors in the disclosed embodiments may be, for example, any type of sensor used in a vehicle to sense an external environment, an environment within the vehicle, a vehicle parameter. The control chip is in communication connection with each sensor through the data conversion chip, and communication, control and feedback between the control chip and each sensor are achieved.
In some embodiments, the plurality of sensors are of the same type. For example, each sensor in the vehicle control system is a camera. Taking fig. 1 as an example, 6 sensors 11 are each provided as a camera. The 6 cameras 11 are respectively connected with the data transmission chip 12, and the data transmission chip 12 is connected with the control chip 13. The video data acquired by the 6 cameras 11 can be transmitted to the control chip 13 through the data conversion chip 12, and the control chip 13 can also communicate with each camera 11 through the data conversion chip 12 to control each camera 11. Also for example, each sensor in the vehicle control system is a radar. Each sensor in the vehicle control system comprises an ultrasonic radar, a millimeter wave radar, a laser radar and the like. The ultrasonic radar may be provided at different positions of the vehicle. The types of the sensors are the same, so that a control chip for controlling the sensors can be directly adopted without newly developing and designing the control chip.
In addition, if the types of the sensors in the vehicle control system are the same, the parameters of the same type of sensor may be set to be different in some embodiments. Such as different resolutions of different cameras, different focal lengths, etc.
In some embodiments, at least some of the sensors are of different types. For example, a vehicle control system includes 6 sensors. Among 6 sensors 11, 2 sensors are cameras, 2 sensors are radars, and 2 sensors are temperature sensors. The disclosed embodiment can realize the communication between the control chip 13 and various sensors of different types through the data conversion chip 12.
In some embodiments, whether the sensors are of the same type or different types, it is also possible to arrange for each sensor to be communicatively connected to a control chip via a data exchange chip.
In some embodiments, as shown in fig. 3, the control chip may further include a plurality of sub-chips; the sensors of the same type are in communication connection with the same sub-chip through a data exchange chip; different types of sensors are in communication connection with different sub-chips through the data exchange chip. As shown in fig. 3, the exemplary setup control chip 13 includes 4 sub-chips, which are a sub-chip 131, a sub-chip 132, a sub-chip 133, and a sub-chip 134. The same type of sensor is communicatively connected to the same sub-chip via the data exchange chip 12. For example, a vehicle control system includes 7 sensors, and the 7 sensors are classified into 3 types of sensors. The sensor 111, the sensor 112, and the sensor 113 are all cameras. Both sensor 114 and sensor 115 are radar. Both sensor 116 and sensor 117 are temperature sensors. The sensor 111, the sensor 112 and the sensor 113 are all connected with the sub-chip 131 through the data exchange chip 12 in a communication mode, the sensor 114 and the sensor 115 are all connected with the sub-chip 132 through the data exchange chip 12 in a communication mode, and the sensor 116 and the sensor 117 are all connected with the sub-chip 133 through the data exchange chip 12 in a communication mode. Because the sensors of the same type can be directly provided with the corresponding chips for communication control, the control chip provided by the embodiment of the disclosure comprises a plurality of sub-chips, the sensors of the same type are in communication connection with the same sub-chip through the data exchange chip, and the sensors of different types are in communication connection with different sub-chips through the data exchange chip, so that software development on a single control chip is avoided to adapt to data transmission of different types of sensors.
In some embodiments, the sensor 11 is communicatively connected to the data exchange chip 12 via a wiring harness; the data exchange chip 12 and the control chip 13 are integrated in the same controller. The serializer 14 is connected with the data exchange chip 12 through a wire harness, and the data exchange chip 12 and the control chip 13 are integrated into the same controller. Since the vehicle needs to collect environmental parameters at different positions of the vehicle or parameters of the vehicle itself, sensors need to be installed at different positions of the vehicle. Therefore, the sensor 11 is connected with the data exchange chip 12 in a communication mode through the wire harness, so that the embodiment of the disclosure is suitable for acquiring the collected data of the sensors arranged at different positions of the vehicle. In order to avoid the direct wire harness connection between the data exchange chip 12 and the control chip 13, the data exchange chip 12 and the control chip 13 are integrated in the same controller according to the embodiment of the disclosure, and the data exchange chip 12 and the control chip 13 may be connected by PHY interface pins and integrated in the same controller, for example.
