Abstract
A transmission control unit (TCU) is one of the types of automotive control unit that is ECU which is used to control the gearing system automatically. This TCU plays a vital position in today’s cutting-edge automobile for automating the manual gearing system.
In modern automatic transmission, the TCU uses sensors to fetch data from the automotive vehicle, and also from the electronic control unit (ECU), in order to calculate, how gear changing control in the vehicle to enhance the overall performance, shift quality and fuel consumption thus improving the sophistication in our daily lifestyles by upgrading to automatic gearing system from manual gearing system and improving the quality of automation. being this important, creating such a highly intelligent and also improved sophisticated control software for the TCU is also becoming challenging. Such system is mainly developed with micro controller which act as sensor, processor, and actuators. If an error or fault is occurring in microcontroller, then it will damage the performance of microcontroller, and which leads to the failure of cascade system which is in contact with the microcontroller. These types of failures can be avoided by adapting the standards created by functional safety ISO (26262). In this project, the different faults that can be occurred in general in ram memory and safety mechanism for those faults has been discussed and implemented.
modern electronic control unit consist of many components. We should ensure the safety of all these components by assigning this with automotive safety integrity level. To make sure the safety, system methodologies followed are partitioning of memory for a different ASIL and developing entire software component according to ASIL depending on applications.
The present paper gives info on configuration and reveal required hardware protection mechanism that are in built and additionally gives software program protection system for memory. For simulation work which we carried out, AURIX TC37X micro controller has been used which is from Infineon technology having 32-bit tri-core architecture.
