Detailed ways

In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are some of the embodiments of the present invention, but not all of them. The specific embodiments described here are only used to explain the utility model, but not to limit the utility model. All other embodiments obtained by persons of ordinary skill in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.

Sensors and control chips in existing vehicles are generally connected in a single-point form to realize communication, control, and feedback between the control chip and sensors. That is, each sensor is connected to the control chip respectively. Since each sensor needs to be connected with the control chip, the control chip needs to control each sensor separately. For example, if the control chip is connected to 6 sensors, it needs to send control commands to each sensor for management and control of the sensors. In addition, the single-point connection method between the sensor and the control chip is highly dependent on the configuration of the control chip. If the sensor parameters are changed, the control chip needs to be modified accordingly, and the redesign and modification of the control chip requires custom development by the control chip supplier, which has high development costs and affects the production cycle. For example, after changing the sensor model, the interface connected to the sensor on the control chip needs to be modified, so the control chip supplier needs to cooperate with customized development. On the one hand, the control chip supplier cooperates with the customized development. , On-site debugging is also required, which affects the production line production rate.

In view of the shortcomings of the prior art described above, an embodiment of the present disclosure provides a vehicle control system. FIG. 1 is a schematic structural diagram of a vehicle control system provided by an embodiment of the present disclosure. As shown in FIG. 1 , the embodiment of the present disclosure provides The vehicle control system includes at least one sensor 11 , a data exchange chip 12 and a control chip 13 . Wherein, the data exchange chip 12 is respectively connected to the sensors 11 in communication. The data exchange chip 12 is communicatively connected with the control chip 13 . The data exchange chip 12 is used to receive the collected data of the sensor 11 and send it to the control chip 13 , and send the control command of the control chip 13 to the sensor 11 . It should be noted that, due to different requirements of vehicles, the embodiment of the present utility model does not limit the number of connected sensors. In FIG. 1 , six sensors 11 are set as an example.

In the embodiment of the utility model, the sensor 11 is used to collect relevant information outside the vehicle, inside the vehicle or related parameters of the vehicle. The embodiment of the utility model does not limit the type of the sensor. Since the data exchange chip 12 is respectively communicatively connected with each sensor 11 , the data exchange chip 12 can receive the data collected by each sensor 11 . Since the data exchange chip 12 is also communicatively connected with the control chip 13 , the data exchange chip 12 can transmit the data collected by each sensor 11 to the control chip 13 . The control chip 13 can send control instructions for controlling each sensor to each sensor 11 through the data exchange chip 12 , so as to realize communication, control, and feedback between the control chip 13 and each sensor 11 .

The data conversion chip 12 in the embodiment of the present disclosure can 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 the control chip 13 sends the control Commands are sent to each sensor 11 individually, so management is more efficient. Taking the vehicle control system including six sensors 11 as an example, in the prior art, the single-point connection between each sensor and the control chip requires the control chip 13 to send control commands to the six sensors 11 respectively. In the embodiment of the present disclosure, since the data conversion chip 12 is provided, centralized platform management can be realized. The control chip 13 can only send a control instruction to control the six sensors 11 to the data conversion chip 12, and the data conversion chip 12 can control the six sensors 11 according to the data conversion chip 13. The instructions to control the 6 sensors.

Since each sensor 11 is communicatively connected to the control chip 13 through the data conversion chip 12, if a different type of sensor is replaced or the sensor parameters are changed, it is not necessary to modify the communication interface of the control chip 13, only the data conversion chip 12 needs to be modified accordingly That's it. Since the modification of the internal algorithm or program of the control chip involves the underlying algorithm of the control chip, it may affect other components that communicate with the control chip or the components inside the control chip. The direct communication connection between 13, if the sensor parameters are changed, only the configuration of the data exchange chip needs to be modified accordingly, and the design of the control chip does not need to be changed, which reduces the dependence on the control chip. The function of the data conversion chip is a communication bridge between the sensor and the control chip, so it is relatively easy to modify the data conversion chip to adapt to the change of sensor parameters, and only need to do basic configuration.

In some embodiments, the communication connection between the data exchange chip and the control chip is based on a time-sensitive network. Since the data exchange chip needs to send the collected data of each sensor to the control chip, in order to ensure a relatively large bandwidth, the embodiment of the present disclosure sets a communication connection based on a time-sensitive network between the data exchange chip and the control chip. Since multiple sensors share the bandwidth, when the data traffic is large, the data streams sent by different sensors will overlap in time and conflicts will occur, making the data transmission delay uncertain. In order to make the communication between each sensor and the control chip have a more stable time attribute, the embodiment of the present disclosure sets a communication connection based on a time-sensitive network between the data exchange chip and the control chip. The time-sensitive network consists of a series of protocol standards, including clock synchronization, data scheduling and network configuration standards, so as to ensure the low latency and high reliability of the network.

In some embodiments, the data exchange chip communicates with the sensor based on serial link GMSL protocol or flat panel display link FPD Link protocol. GMSL (Gigabit Multimedia Serial Links, serial link) is a serial transmission interface standard for vehicles, supports coaxial cable transmission, supports coaxial cable POC power supply, and is suitable for the transmission of video, audio and control signals. FPD Link (Flat Panel Display Link, Flat Panel Display Link) is a technology for point-to-point transmission of high-bandwidth data, which can transmit uncompressed images, and can support HDMI, MIPI DSI input, LVDS/MIPI DSI output, etc.

In some embodiments, as shown in FIG. 2 , the sensor 11 is in communication connection with the data exchange chip 12 through the serializer 14 ; the data exchange chip 12 is in communication connection with the control chip 13 through the deserializer 15 . Wherein, the sensor 11 is connected to the data exchange chip 12 through the serializer 14 , and the data exchange chip 12 is communicatively connected to the control chip 13 through the deserializer 15 . The serializer 14 is used to perform serialization processing on the collected data of the sensor 11 and convert it into a low-voltage serial signal, and then transmit it 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 sends it to the control chip 13 .

In some embodiments, the sensor includes at least one of a camera, a radar, a temperature sensor, a pressure sensor, a speed sensor, an angle sensor, and a gas sensor. The sensor in the embodiments of the present disclosure may be, for example, any type of sensor used in the vehicle to sense the external environment, the environment inside the vehicle, and vehicle parameters. The control chip communicates with each sensor through the data conversion chip to realize communication, control and feedback between the control chip and each sensor.

In some embodiments, the multiple sensors are of the same type. For example, each sensor in a vehicle control system is a camera. Taking FIG. 1 as an example, the six sensors 11 are all configured as cameras. The six cameras 11 are connected to the data transmission chip 12 respectively, and the data transmission chip 12 is connected to the control chip 13 . The video data acquired by the six 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. The sensors in the vehicle control system include ultrasonic radar, millimeter wave radar, laser radar, etc. Ultrasonic radars can also be arranged at different positions of the vehicle. If multiple sensors are of the same type, then the control chip for controlling this type of sensor can be directly used without re-development and design of the control chip.

In addition, if the types of the sensors in the vehicle control system are the same, in some embodiments, the parameters of the sensors of the same type can also be set to be different. For example, different cameras have different resolutions and focal lengths.

In some embodiments, at least some of the sensors are of different types. For example, a vehicle control system includes 6 sensors. Among the six sensors 11, two sensors are cameras, two sensors are radars, and two sensors are temperature sensors. The embodiment of the present disclosure can realize the communication between the control chip 13 and various types of sensors through the data conversion chip 12 .

In some embodiments, regardless of whether the types of the sensors are the same or different, it can also be set that each sensor is communicatively connected to a control chip through a data exchange chip.

In some embodiments, as shown in Figure 3, the control chip can also include a plurality of sub-chips; the same type of sensors communicate with the same sub-chip through the data exchange chip; different types of sensors communicate with different sub-chips through the data exchange chip . As shown in FIG. 3 , the exemplary configuration control chip 13 includes four sub-chips, namely a sub-chip 131 , a sub-chip 132 , a sub-chip 133 and a sub-chip 134 . Sensors of the same type are communicatively connected to the same sub-chip through the data exchange chip 12 . For example, the vehicle control system includes 7 sensors, which are divided 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 radars. Both sensor 116 and sensor 117 are temperature sensors. The sensor 111, the sensor 112 and the sensor 113 are all communicatively connected with the sub-chip 131 through the data exchange chip 12, the sensor 114 and the sensor 115 are all communicatively connected with the sub-chip 132 through the data exchange chip 12, and the sensor 116 and the sensor 117 are all connected through the data exchange chip 12 Communicatively connected with the chiplet 133 . Usually, sensors of the same type can be directly provided with corresponding chips for communication control, so the embodiment of the present disclosure sets the control chip to include multiple sub-chips, and the same type of sensors communicate with the same sub-chip through a data exchange chip. The data exchange chip communicates with different sub-chips to avoid software development for a single control chip to adapt to the data transmission of different types of sensors.

In some embodiments, the sensor 11 is communicatively connected with the data exchange chip 12 through a wire harness; the data exchange chip 12 and the control chip 13 are integrated in the same controller. The serializer 14 is connected to 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 locations of the vehicle or parameters of the vehicle itself, it is necessary to install sensors at different locations of the vehicle. Therefore, in the embodiment of the present disclosure, the sensor 11 is communicatively connected with the data exchange chip 12 through a wiring harness, so as to adapt to acquiring data collected by sensors installed at different positions of the vehicle. In order to avoid the data exchange chip 12 and the control chip 13 being directly connected by a wire harness, the embodiment of the present disclosure sets the data exchange chip 12 and the control chip 13 to be integrated in the same controller, and the data exchange chip 12 and the control chip 13 can be connected through the PHY interface pin Connected and integrated in the same controller.
