Abstract
In Continental the, Electronic Control Unit (ECU’s) software consists of 2 parts, the basic software which is the generic part and the application software which does the product specific functionality. The project specific functionality depends upon the product type, like Body domain controller, immobilizer etc. Before the ECU is going to mass production, the controller has to be validated i.e., software and hardware. The main reason is to ensure, that once the ECU is fitted to the vehicle and there is a recall for ECU, it involves additional cost to the organization. The validation of the software includes, checking of the micro controller input, outputs, peripheral drivers, the initialization of the drivers, the timing measurement of the different components. All the parameters are controlled by the generic and application specific modules, and can be configured via configuration tool, manual configuration etc. Since the SW modules are complex and huge, so its need to perform validation of the SW modules manually. This is time consuming process, as it involves checking many c file, configuration files etc. The proposal is to automate the process using Python programming, which interacts with the C code, configuration files, debugger, interacting with the ECU’s peripherals, components and validate the Software parameters before going for series production. In the proposed method the different steps can be automated for different micro-controllers i.e., Renesas RL78 and RH850 used in the ECU’s and different architecture i.e., AUTOSAR and NON-AUTOSAR will be considered and the results will be compared with the manual validation effort and accuracy.
Highlights
In Continental, there are many business units and one among them is Body and Security Business unit
Few pins are used for specific functions and the values for configuration like the type of port, initial values, directions, polarity are configured by the information provided in the Hardware Software Interface (HSI) sheets
The generated output is in the html or excel format for readability, which is being compared with the HSI sheets
Summary
In Continental, there are many business units and one among them is Body and Security Business unit. The main product lines include Gateways, Intelligent body domain controller, Tire pressure monitoring systems, RF receivers, Immobilizers, Seat controllers and Comfort systems. The product is developed for different Original Equipment. Revised Manuscript Received on June 10, 2020.
