specific Embodiment

[0029] The reversing light circuit and the right turn signal circuit are selected to complete the circuit function design by using the flexible configuration method. Assuming that the reversing light switch is a high effective input switch value, the reversing light output needs to be driven by a low-side power output, and the output drive mode is normal high; the right steering switch is a low effective input switch value, and the right steering output needs a high-side power output drive , the output drive mode is blinking. Select terminal No. 2 on port B and terminal No. 4 on port C of the switch input module 4 as the input ports of the two switch signals, define their port numbers as 0x02 and 0x04 respectively, and select the high-side power output port Terminals 8 and 9 on A are driven as high-side outputs. Select terminals 11 and 13 on the low-side power output port F as low-side output drivers, and define their port numbers as 0x08, 0x09, 0x11, and 0x13, respectively. ...

Abstract

The invention relates to a heavy-duty car CAN control system flexibility configuration method based on a bussing technique. Step 1, an upper machine flexibility configuration module 1 produces configure relation of a car body system; step 2, the upper machine flexibility configure module 1 transmits the configure relation to a central controller module 2 for storage; step 3, the central controller module 2 detects the input port state, and the meaning of the input port is obtained by the configure relation stored in a non-volatile storage; step 4, level signals are applied to a power supply control module 3 which is pulled on switching value input detection to point to high valid input and low valid input, and the current state of the input switching value is detected; step 5, an output port controlled by the input port and the output mode of the output port are detected; and step 6, a power output module finishes power output. The input and output functions of a hardware port are changed by the method by changing the car body configure information, the function of the system flexibility configure is completed, and the configure method is applied to heavy trucks of various car models below the same hardware platform.

Description

technical field [0001] The invention belongs to the field of automotive electronics, and in particular relates to a method for flexible configuration of a heavy-duty vehicle CAN control system based on bus technology. Background technique [0002] With the continuous development of automobile technology, the average number of independent electronic devices and systems in each automobile has exceeded 80. The electronic system will inevitably have more and more input and output channels in the electronic control unit (ECU) of the car to collect the signal and control the power output. Produce different models. When purchasing heavy-duty trucks, users also purposely choose the electrical configuration on the body, so the parameters such as input and output channel ports and port types required by each model are inconsistent. When designing an automotive electronic control unit (ECU) on hardware, many kinds of hardware circuits may be required in order to take care of differen...
