Parameterization process and system for a vehicle

A method for a vehicle, comprising:

• sending a first parameter of a plurality of parameters to a third dedicated address of a plurality of addresses in memory via instructions;
• updating a parameter flag value of a parameter flag in a first dedicated address of the plurality of addresses in memory via an electronic control unit (ECU) in the vehicle;
• updating a cyclic redundancy check (CRC) value for the first parameter in a second dedicated address of the plurality of addresses in memory via the ECU;
• writing a first parameter value for the first parameter in the third dedicated address in memory and a CRC value of the first parameter in a fourth dedicated address in memory via the ECU;
• sending remaining parameters in the plurality of parameters to dedicated addresses in memory via instructions;
• writing remaining parameter values and CRC values of the plurality of parameters to dedicated addresses in memory via the ECU;
• reading parameter values and CRC values for the plurality of parameters in dedicated addresses in memory of the ECU via instructions;
• comparing read values with expected values for the plurality of parameters and corresponding CRC values for the plurality of parameters in dedicated addresses in memory via instructions;
• evaluating the read values and the expected values for the plurality of parameters and corresponding CRC values for the plurality of parameters to detect differences between the read values and the expected values;
• and
• implementing from among a first data control scheme and a second data control scheme in response to a comparison and evaluation of the read values and the expected values for the plurality of parameters and corresponding CRC values for the plurality of parameters.

A system, comprising:

• a vehicle comprising various systems and components including an electronic control unit (ECU) communicatively coupled to one or more controllers that configure sensors and actuators;
• the ECU that comprises at least one processor and one memory of a plurality of memories with dedicated addresses of a plurality of addresses for a parameter flag, a corresponding CRC value for the parameter flag;
• parameter values for a plurality of parameters, and corresponding CRC values for the plurality of parameters, and wherein configuring the sensors and actuators incudes updating the parameter values for the plurality of parameters associated with vehicle performance to control the sensors and actuators;
• and
• a computing device that comprises a user interface and a processor operatively coupled to the user interface and executable instructions in at least one memory, that when executed, cause the processor to:
• execute a service tool comprising instructions and pre-programmed algorithms that connects to the ECU for parameterization;
• send parameters to dedicated addresses in memory that configure the various systems and components of the vehicle, including the ECU;
• read a parameter flag value of the parameter flag and the corresponding CRC value of the parameter flag in dedicated addresses in memory of the ECU;
• read parameter values of the plurality of parameters and corresponding CRC values of the plurality of parameters in dedicated addresses in memory of the ECU;
• calculate CRC values for the plurality of parameters based on parameter values of the plurality of parameters sent to the ECU;
• compare read values of parameter values for the plurality of parameters with expected values of initial parameter values sent to the ECU via instructions;
• compare corresponding CRC values for the plurality of parameters from memory of the ECU with expected values of the CRC values that are calculated via instructions based on initial parameter values for the plurality of parameters;
• and
• detect invalid values and differences between the read values and the expected values for the parameter flag value of the parameter flag, the corresponding CRC value of the parameter flag, parameter values for the plurality of parameters, and the corresponding CRC values of the plurality of parameters.
