The invention discloses a vehicle instrument configuration parameter calibration method. The method comprises the following steps that 1, calibration equipment sends a request for entering a vehicle instrument reply to enter an extension mode to a vehicle instrument; 2, the calibration equipment sends a seed request to the vehicle instrument, and the vehicle instrument replies corresponding seed information to the calibration equipment according to the seed request; 3, the calibration equipment assembles the seed information into a plaintext, performs encryption calculation to form a ciphertext, and replies the ciphertext to the vehicle instrument; 4, the vehicle instrument decrypts the ciphertext into the plaintext, and compares and verifies the plaintext with the seed information; 5, ifverification succeeds, the calibration equipment writes calibration parameters into the vehicle instrument; 6, the calibration equipment reads the calibration parameters from the vehicle instrument; 7, the vehicle instrument replies the calibration parameters to the calibration equipment; 8, the calibration equipment compares the calibration parameters; and 9, if comparison is successful, the calibration equipment continues to write the next calibration parameter into the vehicle instrument. In the invention, instruments required by various instantiated vehicle types can be formed.
本发明公开了一种车用仪表配置参数标定方法,如下步骤:1:标定设备向车用仪表发送进入车用仪表回复进入扩展模式的请求;2:标定设备向车用仪表发送种子请求,车用仪表根据种子请求向标定设备回复对应的种子信息;3:标定设备将种子信息组装成明文并进行加密计算形成密文,回复给车用仪表;4:车用仪表将密文解密成明文,并将明文与种子信息进行对比校验;5:若校验成功,则标定设备给车用仪表写入标定参数;6:标定设备向车用仪表读取标定参数;7:车用仪表向标定设备回复标定参数;8:标定设备对标定参数进行比较;9:若比较成功,则标定设备继续向车用仪表写入下一个标定参数。本发明能形成各种实例化车型所需的仪表。
