Abstract

The invention provides a data detection method and device. The method comprises the following steps: reading data corresponding to a target address in a storage area, and obtaining the verification value of the data by adopting a preset verification method; according to the verification value of all the data in the storage area, and a standard verification value pre-stored in a preset address in the storage area, determining whether the data stored in the storage area has a fault or not. The data detection method and device realize the safety detection of the data in the memory in an automobile electronic control unit, and the failure of the data in the memory can be found in time.

Description

technical field [0001] The present application relates to the technical field of data detection, in particular to a data detection method and device. Background technique [0002] The automotive electronic control unit is a control device composed of integrated circuits used to implement a series of functions such as data analysis, processing and sending. Usually, the automotive electronic control unit adopts a design structure of one or more central processing units (Central Processing Unit, CPU) combined with peripheral chips, such as figure 1 shown. [0003] The memory is an important part of the CPU, which is mainly used to store the running program, related data, parameters, etc. of the controller. If the data in the memory fails and is not discovered in time, it will cause abnormal function of the electronic control unit of the car, and even cause the failure of the entire controller function, resulting in serious accidents. [0004] Therefore, how to realize the sa...
