The invention discloses a method for setting automobile instrument configuration parameters, which comprises the following steps of: starting and electrifying an automobile, and entering an automobile instrument board extension program; the setter sends a random number request to the motormeter, and the motormeter replies corresponding random number information to the setter according to the random number request; the setter assembles the random number information into a plaintext, carries out encryption calculation to form a ciphertext, and replies the ciphertext to the automobile instrument; the motormeter decrypts the ciphertext into a plaintext, and compares and verifies the plaintext with the random number information; if verification succeeds, the setter writes setting parameters into the automobile instrument; the setter reads set parameters from the automobile instrument; the automobile instrument replies setting parameters to the setter; the setter compares the setting parameters; and if the comparison is successful, the setter continues to write the next setting parameter into the automobile instrument. According to the invention, instruments required by various instantiated vehicle types can be formed.

    本发明公开了一种汽车仪表配置参数设置的方法,如下步骤:汽车启动上电,进入汽车仪表板扩展程序;设置器向汽车仪表发送随机数请求,汽车仪表根据随机数请求向设置器回复对应的随机数信息;设置器将随机数信息组装成明文并进行加密计算形成密文,回复给汽车仪表;汽车仪表将密文解密成明文,并将明文与随机数信息进行对比校验;若校验成功,则设置器给汽车仪表写入设置参数;设置器向汽车仪表读取设置参数;汽车仪表向设置器回复设置参数;设置器对设置参数进行比较;若比较成功,则设置器继续向汽车仪表写入下一个设置参数。本发明能形成各种实例化车型所需的仪表。
