LIN is used to control the ECU, a simple driving device for automobiles such as sensors and actuators on the network, and has the advantage of configuring the network with low development cost. The LIN protocol is generally used with CAN communication and has a limited range of use compared to CAN communication. The LIN protocol enables low-cost communication systems for branched systems in the car, and can reduce costs by using a single line. LIN communication enables signal-based application interactions and can consist of a network containing multiple slaves to a single master.

Thus, communication bus physical connection 110 may include a comparison circuit or A / D converter for converting physical signals into digital signals.

Meanwhile, the protocol processor 120 generates a power driving signal according to the digitally converted signal of the automotive communication protocol signal received from the communication bus physical connection unit 110, and outputs the power driving signal to the power driving driver 130.

The protocol processor 120 may obtain address information, protocol information, and related data information stored in the data storage 140 using the data storage 140. The protocol processor 120 may generate a power driving signal based on the obtained address information and protocol information and a signal received from the communication bus physical connection unit 110.

The protocol processor 120 may perform hardware signal processing to interpret a communication protocol signal for an automobile and output a power driving signal. The protocol processor 120 may be manufactured through a hardware design using a switching device and various circuit devices. Accordingly, the protocol processor 120 may perform protocol processing without undergoing software signal processing using a conventional MCU or microprocessor.

3 is a block diagram illustrating a driving device for a vehicle according to an exemplary embodiment of the present disclosure.

Referring to FIG. 3, an automobile driving apparatus 300 according to an embodiment of the present invention is connected to a CAN physical connection unit 310 and a CAN physical connection unit 310 connected to a CAN communication bus to perform CAN communication with the outside. The hardware CAN communicator 320, the power driver 330 for transferring power to the driver 350 under the control of the CAN communicator 320, a data storage unit 340, and a driver 350 are included.

The vehicle driving apparatus 300 according to an exemplary embodiment of the present invention illustrated in FIG. 3 applies the configuration of the communication module 100 of FIG. 2 to be driven in a CAN communication protocol. Therefore, similar descriptions for components similar to those of FIG. 2 will be omitted.

The CAN physical connection 310 directly connects with the CAN communication bus to convert and output a CAN communication signal into a digital signal. The CAN physical connection unit 310 may receive two wire inputs (differential signals, CAN High and CAN Low) through two input terminals. In addition, the CAN physical connection 310 may distinguish between the recessive bit and the dominant bit according to a signal transmitted through two lines. For example, if the differential voltage between CANH and CANL is greater than the minimum threshold, the dominant bit, (logical 0), and the state less than the minimum threshold are recessive bits (logical 1). More specifically, when both CAN H and CAN L are 2.5V, recessive and CANH may be determined as dominant bit when 3.5V and CANL is 1.5V. The dominant bit and the recessive bit may have an arbitration relationship. For example, the CAN physical connection unit 310 may output the dominant bit first. Accordingly, the CAN physical connection unit 310 generates a digital signal through voltage comparison and outputs the digital signal to the hardware CAN communication unit 320.

The hardware CAN communication unit 320 interprets the digitally converted CAN communication signal (data stream) by using a hardware designed circuit and outputs a driving command. CAN communication unit 320 may be designed in hardware to be suitable for the interpretation of the CAN communication protocol. Thus, it can replace expensive CAN embedded MCU. In addition, a ROM type data storage unit 340 may be used for protocol analysis of the hardware CAN communication unit 320.

The CAN protocol communication signal is an asynchronous method in which there is no separate clock signal. The CAN protocol communication signal includes a start bit indicating the start of one message, an end bit indicating the end of the message, and an identification field uniquely indicating the message, and a data field having a maximum of 8 bytes in the transmitted message frame. It may include. The hardware CAN communication unit 320 may include a hardware processing circuit that compares the CAN protocol communication signal with address information and protocol information stored in the data storage unit 340. In addition, the hardware CAN communication unit 320 may quickly generate a driving command according to a message identification field and a data field according to a result of a simple comparison operation rather than the existing software process.

The power driving driver 330 generates power according to a driving command output from the hardware CAN communication unit 320 and transmits the power to the driving unit 350.

The driver 350 performs an operation according to the power received from the power driving driver 330. As described above, the driving unit 350 may be any one of an automobile driving apparatus, and may include a motor or the like to receive and operate power from the power driving driver 330.

4 is a block diagram illustrating a driving device for a vehicle according to another exemplary embodiment of the present disclosure.

The vehicle driving apparatus 400 according to an exemplary embodiment of the present invention illustrated in FIG. 4 applies the configuration of the communication module 100 of FIG. 2 so as to be appropriately driven by the LIN communication protocol. Therefore, similar descriptions for components similar to those of FIG. 2 will be omitted.

The LIN physical connection and communication unit 410 directly connects to the LIN communication bus, converts the LIN communication signal into a digital signal, and outputs the power driving signal to the power driving driver 420 based on this.

As described above, the LIN protocol is a serial communication protocol for efficiently controlling a driver or sensor, which can be referred to as a mechatronic node, on a distributed network, and is mainly used in an electric device of an automobile. Unlike CAN, LIN networks do not use bus arbitration and can consist of one master and multiple slaves. In addition, the LIN protocol signal for LIN network communication may be transmitted in the form of serial data through the LIN communication bus.

Accordingly, the LIN physical connection and communication unit 410 receives the LIN protocol signal through the physical connection, converts the LIN protocol signal into a digital signal, and drives the hardware circuit based on the power drive signal for driving the driving unit 440. The output may be output to the power driving driver 420.

The LIN physical connection and communication unit 410 may be designed in hardware to be suitable for the interpretation of the LIN communication protocol. Therefore, it can replace expensive LIN embedded MCU. In addition, a ROM type data storage unit 430 may be used for the LIN physical connection and protocol analysis of the communication unit 410.

The LIN data frame may be composed of a sync break field, a sync field, an identifier field, a data field, and a checksum field, and may be divided into a header and a response part. The LIN physical connection and communication unit 410 may include a hardware processing circuit that compares the LIN protocol communication signal with address information and protocol information stored in the data storage unit 430. The LIN physical connection and communication unit 410 may quickly generate a power driving signal according to a result of a simple comparison operation by hardware rather than the existing software process.

The power driving driver 420 generates power and transmits the power to the driving unit 440 according to the driving command output from the LIN physical connection and communication unit 410.

The driver 440 performs an operation according to the power received from the power driving driver 420. As described above, the driving unit 440 may be any one of driving devices for automobiles, and may include a motor or the like to receive and operate power from the power driving driver 440.
