Description
Technical Field
The application relates to the technical field of electronic control engines, in particular to a data writing method, a data writing device, data writing equipment and a data writing storage medium of an electronic control unit.
Background
When the electric control engine is in a test run or is off-line in a whole vehicle factory, related data needs to be written into an Electronic Control Unit (ECU) through service tool software and stored in the ECU. The data written in the ECU comprises a plurality of information such as ECU software version number, engine number, order number and the like. When data is written into the ECU, a plurality of data to be written are mainly written into a service tool software interface, a write request is initiated by one key, and the plurality of data are sequentially written into the ECU. When the service tool software writes a plurality of data into the ECU, each write data command is sequentially transmitted. After one data writing instruction is sent, another data writing instruction is sent again after waiting for fixed time until the data writing instruction is sent. When the service tool software continuously sends a data writing command to the ECU, the situation that the written data cannot be stored in the EEP is occasionally existed. The writing operation of the EEP storage area needs time, and if the interval time of two data writing instructions of the service tool software is too short, new data received in the writing operation process of the EEP storage area cannot be stored. If the interval between two times of data writing of the service tool software is long, the whole data writing process is too long, and the production beat is influenced.

s10, periodically detecting the storage area status of the EEP in the electronic control unit.
Specifically, as shown in fig. 2, step S10 includes:
and S101, periodically reading the state value of the storage area of the EEP in the electronic control unit. The reading period may be set according to actual needs, and may be set to 3s, 5s, or the like, for example.
The storage area state values include an idle state value and a write operation state value. The idle state value corresponds to the state that the storage area of the charged erasable programmable read-only memory EEP is in an idle state, and the write operation state value corresponds to the state that the storage area of the charged erasable programmable read-only memory EEP is in a write operation state. The idle state value and the write operation state value of the storage area state value may be set to 0 and 1, respectively, or the idle state value and the write operation state value of the storage area state value may be set to 1 and 0, respectively, which may be specifically selected according to actual needs. When the storage area state of the charged erasable programmable read-only memory EEP is an idle state, setting the storage area state value as an idle state value; when the storage area state of the charged erasable programmable read-only memory EEP is a write operation state, the storage area state value is set as a write operation state value.

Specifically, whether the read storage area state value of the charged erasable programmable read-only memory EEP is an idle state value or a write operation state value is identified. For example, determining whether the read storage area state value is 0 or 1 may determine whether the current storage area state is in an idle state or a write operation state.
And S20, when the storage area state of the charged erasable programmable read-only memory EEP is detected to be an idle state, sending an ECU (electronic control Unit) data writing instruction to the electronic control unit, so that the electronic control unit executes writing operation according to the ECU data writing instruction, and writing the data to be written into the storage area of the charged erasable programmable read-only memory EEP. And the ECU data writing command is used for starting data writing operation by the electronic control unit according to the ECU data writing command.

The data to be written may include at least one of ECU software version number, engine number, order number, and the like.
For example, the idle state value and the write operation state value of the storage area state value are respectively set to 0 and 1, the storage area state value of the charged erasable programmable read-only memory EEP is periodically read, whether the read storage area state value of the charged erasable programmable read-only memory EEP is 0 or 1 is identified, and if the storage area state value is 0, the current storage area state is represented as the idle state, and an ECU write data command is sent.
And if the state of the EEP storage area of the charged erasable programmable read only memory is detected to be a writing operation state, the ECU data writing instruction is not sent.
Specifically, if the storage area state value of the EEP is the write operation state value, the ECU does not send the data writing command, and continues to periodically detect the storage area state of the EEP in the ECU.
For example, the idle state value and the write operation state value of the storage area state value are set to 0 and 1, the storage area state value of the charged erasable programmable read only memory EEP is periodically read, whether the read storage area state value of the charged erasable programmable read only memory EEP is 0 or 1 is identified, and if the storage area state value is 1, the current storage area state is represented as the write operation state, and the operation of sending the ECU write data command is not executed.

As shown in fig. 5, in some embodiments, the detection module 10 includes:
a reading unit 101, configured to periodically read the state value of the storage area of the charged eeprom.
The reading period may be set according to actual needs, and may be set to 3s, 5s, or the like, for example. The storage area state values include an idle state value and a write operation state value. The idle state value corresponds to the state that the storage area of the charged erasable programmable read-only memory EEP is in an idle state, and the write operation state value corresponds to the state that the storage area of the charged erasable programmable read-only memory EEP is in a write operation state.
And the judging unit 102 is configured to judge whether the storage area state is an idle state or a write operation state according to the read storage area state value.
Specifically, whether the read storage area state value of the charged erasable programmable read-only memory EEP is an idle state value or a write operation state value is identified. For example, the idle state value and the write operation state value of the storage area state value may be preset to 0 and 1, respectively, and whether the read storage area state value is 0 or 1 may be determined, that is, whether the current storage area state is in the idle state or the write operation state may be determined.
