Vehicle calibration system and vehicular development and debugging system

A vehicular development and debugging system, comprising:

• a computer device and a bus adapter, wherein
• the computer device comprises a processor, a readable storage medium, a communication bus, and a communication interface;
• wherein
• the readable storage medium is configured to store programs of performing an automatic reading and writing method of a calibration signal, and the processor is configured to execute the programs of performing the automatic reading and writing method of the calibration signal;
• the processor, the readable storage medium, and the communication interface communicate with the bus adapter via the communication bus;
• the bus adapter is configured to read the calibration signal from an ECU, and further to distribute to the ECU a write value generated after the processor performs the automatic reading and writing method of the calibration signal;
• and
• the automatic reading and writing method of the calibration signal comprises:
• creating corresponding mapping system variables respectively for calibration signals in a calibration module;
• assigning an initial value to the mapping system variables;
• for a calibration signal defined as a calibration variable, associating an assignment function to an asynchronous function, wherein the assignment function is a mapping system variable write function of a to-be-written target value;
• when the calibration variable is written, distributing, by the asynchronous function, a write command and a read command to the calibration module, and then returning immediately, wherein a call of the asynchronous function is completed;
• and/or
• for a calibration signal defined as a writable observation variable, associating the assignment function to the asynchronous function, wherein the assignment function is the mapping system variable write function of the to-be-written target value;
• when the writable observation variable is written, distributing, by the asynchronous function, the write command and the read command to the calibration module, and then returning immediately, wherein the call of the asynchronous function is completed, wherein the processor is further configured to automatically associate an assignment function of a mapping system variable to an asynchronous function, such that writing to the mapping system variable triggers the asynchronous function to perform a write and read operation for the corresponding calibration signal with the ECU.
