Abstract

The invention provides a method and a system for managing data in a nonvolatile memory of an automatic transmission. The method comprises the steps as follows: presetting each statistical parameter of the automatic transmission; determining whether a control unit of the automatic transmission is powered on for the first time after the control unit of the automatic transmission is powered on: if the control unit is powered on for the first time, each statistical parameter of the automatic transmission is initialized, otherwise, a datum corresponding to each statistical parameter of the automatic transmission is read from the nonvolatile memory; updating the corresponding datum according to an updating condition of each statistical parameter of the automatic transmission till the control unit of the automatic transmission is powered down; storing the current datum of each statistical parameter of the automatic transmission in the nonvolatile memory when the control unit of the automatic transmission is powered down. With adoption of the method and the system, key data required by after-sales service, maintenance and the like can be obtained, the data support is provided for safety and risk analysis work, and the important support is supplied to improvement of product quality.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to a data management method and system in a non-volatile memory of an automatic transmission. Background technique [0002] An automatic transmission is a transmission device that can automatically shift gears according to the vehicle speed and engine speed relative to the manual transmission. [0003] Various automatic transmission failures appearing in the market make people pay more and more attention to the quality of automatic transmissions. Therefore, how to effectively improve the quality of automatic transmissions, including the research and development design stage and after-sales service stage, has become an urgent problem in this field. . [0004] In practical applications, the data of the automatic transmission can be counted to obtain the working history status of the key components of the automatic transmission, and provide effective data support for a...
