Client was looking for design house for supporting the vehicle side diagnostics design for their end solution, as off the shelf vehicle diagnostics devices or solutions does not support majority of the client’s requirements.
Vehicle side diagnostics design includes support for vehicle diagnostics communications modules / services over various vehicle interfaces like CAN 2.0, CAN FD, CAN SWC and K / L Line etc.
In additional to core vehicle diagnostics requirements, customize requirements around device security, device FOTA, host communication interface, power management where the part of the solution to be developed.
Solution also demands customized and high-performance hardware firmware interface design for communication between Application Host and Vehicle Diagnostics part of the heterogeneous solution
Vehicle Diagnostic & real time services - 32-bit MCU running FreeRTOS
Interface & Protocol design for Application Host and Vehicle Diagnostics communication
Vehicle Ignition detection
Diagnostics Protocols: OBD II Protocol
