Description

Technical Field

[0001] This utility model relates to the field of automotive controller technology, and in particular to an automotive controller power supply and communication system. Background Technology

[0002] A car controller generally refers to an electronic control unit used to control the vehicle's electrical systems. It is an important component of a car. Car controllers typically use separate power supply and communication systems for power supply and information transmission. Current technologies generally improve the power supply or communication separately for controllers. This results in the need to integrate a large number of electronic components into the circuit to achieve the functions of power supply and communication. This not only increases the number of electronic components used, but also makes it difficult to maintain the stability of the circuit due to its complex structure. Furthermore, the large number of electronic components increases the load on the vehicle body, and the repair and maintenance process is also very complicated, causing trouble for car manufacturing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a power supply and communication system for an automotive controller, which solves the technical problems of the large number of electronic components and complex structure of automotive controllers, making them difficult to repair and maintain. It simplifies the number of electronic components for power supply and communication, making repair and maintenance much more convenient.

[0005] Furthermore, the telecommunications module includes current-limiting resistors R12, R13, R15, and R16 connected to the TXDCAN0, RXDCAN0, TXDCAN0, and RXDCAN0 ports on the control chip. The communication signals sent by the microprocessor module are transmitted to the control chip through the current-limiting resistors R12, R13, R15, and R16, and the filtered signals are received by the CANH0, CANL0, CANH1, and CANL1 ports of the control chip.

[0006] Furthermore, the first signal module consists of a common-mode inductor L4, shunt resistors R17 and R18, and the CANH0 and CANL0 interfaces of the control chip transmit communication signals to the outside through the common-mode inductor L4.

[0007] Furthermore, the power module consists of a 5V power supply and a power supply chip. The 5V power supply is connected to the IN interface of the power supply chip, and the OUT interface of the power supply chip outputs 3.3V power to the telecommunications module.

[0008] Furthermore, the power supply and communication system also includes a second signal module, which has the same circuit structure as the first signal module.

[0009] Furthermore, the microprocessor module uses a microprocessor chip of model E3640.

[0010] Furthermore, the control chip is model TLE9278.

[0011] By employing the above technical solution, this utility model provides a power supply and communication system for an automotive controller, which has at least the following beneficial effects:

[0012] 1. This utility model, through the synergistic effect of a microprocessor module, a telecommunications module, and a power supply module, can not only transmit vehicle information through the microprocessor module and the telecommunications module, but also provide stable power to the electronic components of the vehicle body through the telecommunications module and the power supply module.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Due to the large number of electronic components and complex structure of existing automotive controllers, which makes them difficult to repair and maintain, please refer to [the relevant documentation / reference]. Figure 1 - Figure 6 This embodiment proposes a power supply and communication system for an automotive controller, which simplifies the number of electronic components for power supply and communication, making maintenance and repair very convenient. The system includes a microprocessor module 1, and further includes an electrical module 2, a first signal module 3, and a power supply module 5 for communication and power supply with the automotive controller. The electrical module 2 includes current-limiting resistors R12, R13, R15, and R16 connected to the TXDCAN0, RXDCAN0, TXDCAN0, and RXDCAN0 ports on the control chip. Communication signals from the microprocessor module 1 are transmitted to the control chip through the current-limiting resistors R12, R13, R15, and R16, and are controlled by the CANH0 pin of the control chip. The CANL0, CANH1, and CANL1 ports receive filtered signals. The first signal module 3 consists of a common-mode inductor L4 and shunt resistors R17 and R18. The CANH0 and CANL0 interfaces of the control chip transmit communication signals to the outside through the common-mode inductor L4. The power supply module 5 consists of a 5V power supply and a power supply chip. The 5V power supply is connected to the IN interface of the power supply chip, and the OUT interface of the power supply chip outputs 3.3V power to the telecommunications module 2. The power supply and communication system also includes a second signal module 4, which has the same circuit structure as the first signal module 3. The microprocessor module 1 uses an E3640 microprocessor chip, and the control chip is a TLE9278.

[0024] After the vehicle control chip is powered normally, the microprocessor module 1 can communicate with the control chip via SPI to program and configure its internal registers, realizing functions such as power supply voltage selection, CAN specific frame wake-up, fault feedback, and watchdog timer. After configuring the control chip functions, as long as a wake-up source signal is received, the control chip of the telecommunications module 2 can power the entire vehicle system. After the system is powered normally, it can receive CAN or CAN-FD frame signals from the bus. The CAN or CAN-FD signals on the bus enter the control chip of the telecommunications module 2 through a filtering circuit. The control chip of the telecommunications module 2 parses them and transmits information to the microprocessor module 1 according to the communication protocol, thus completing the signal receiving function. Similarly, the microprocessor module 1 can also send signals to the control chip of the telecommunications module 2 in the same way. The control chip of the telecommunications module 2 then converts them into CAN or CAN-FD signals that conform to the communication protocol and transmits them to the main control chip. Online, the power module enables signal transmission. It provides rectified current to the telecommunications module 2, but this current needs to be regulated and converted by the telecommunications module 2 before being supplied to the electronic system of the entire vehicle. This ensures the safe and stable operation of the circuit system. Through the synergistic effect of the microprocessor module, telecommunications module, and power supply module, vehicle information can be transmitted between the microprocessor module and the telecommunications module. It can also provide stable power to the electronic components of the vehicle through the telecommunications module and the power supply module, enabling efficient communication and power supply between vehicle components. The structure is very simple, reducing maintenance difficulty and significantly improving the work efficiency of staff. Through the collaborative work of the first signal module, the second signal module, and the telecommunications module, information from multiple sources can be processed simultaneously. Multiple vehicle information can be efficiently sent to the microprocessor module through the telecommunications module, which not only improves the efficiency of information processing but also increases the types of information processed, greatly enhancing the information processing capability.

[0025] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
