Instrument Cluster for Mainstream Vehicles​

A case study​

Client: Global Automotive Tier1

Technology

AUTOSAR Architecture, Developing software in C/C++
  • 2 MCUs System with ARM cores
  • Inter-Processor Communication (IPC)
  • 2 board (intelligent & front end) APX design
  • OSEK RTOS
  • Greenhills Integrity RTOS with support for separate VAS & Memory protection

Safety-related Functions
  • MOST (Media Oriented System Transport) connection to the infotainment system
  • High speed CAN connection & Open GLE graphics

Services

Cockpit electronic products development, including digital instrument clusters, information displays, infotainment, head-up displays, telematics, cockpit domain controllers, and the autonomous driving platform.

Challenges

  • 2 Instrument Cluster projects for two of the biggest car manufacturers globally
  • 1600 defects to solve
  • 28+ features to implement
  • 100% distributed environment where communication and constant synchronizing with other teams were the key elements for success
  • NO clarity concerning the specifications and the technologies used – at kick off.

Solution

Our team together with our client’s mirror team has taken the responsibility of delivering the next generations of Instrument clusters for one of the largest global brands in Automotive. We managed to do so by focusing on good quality development and integration.

The client acquired more business on which he could not focus without the help of RINF TECH. RINF TECH’s team worked on the following:

  • Software Development – Embedded programming – C language
  • AUTOSAR modules integrations
  • Hardware bring-up for new Hardware Instrument Clusters
  • Vector tools for AUTOSAR

Tasks for:

  • Illumination – controls the PWM for led
  • Pointers – controls the pointers (speed, RPM)
  • Button – handles the input from Board Computer button
  • Check Controls – controls the fault indicators
  • Dimming – controls the intensity of the PWM
  • Odometer – counts the trip and the total kilometers traveled
  • TMM – time
  • Board computer – consumption, trip info, range
  • LDM – adaptive cruise control, dynamic cruise control Tasks for Drivers Team
  • Complex device drivers (MCU, Head-up Display, Real Time Clock, Sound, InputOutput Controller)
  • SAFETY Controller
  • CAN Wrapper
  • Diagnostics
  • Power Management
  • Inter-processor Proxies (between Control and Graphics Processors)
  • AUTOSAR Core Components integration and configuration
  • Hardware Bring-up
  • CAAM crypto driver for iMX6
  • AVB stack
  • RDA encryption
  • MOST communication
  • IPSEC certificates
  • SOMEIP components
  • NAND/NOR/Filesystem code
  • Integrity OS
  • DLT
  • IPC encryption
  • HUD
  • HMI
  • VideoDecoder/Renderer updates
  • CoreDump implementation
  • CarModel code
  • Bootloader code
  • Complex device drivers (MCU, Head-up Display, Real Time Clock, Sound, InputOutput Controller)
  • SAFETY Controller
  • CAN Wrapper
  • Diagnostics
  • Power Management
  • Inter-processor Proxies (between Control and Graphics Processors)
  • AUTOSAR Core Components integration and configuration
  • Hardware Bring-up

Methodology

In order to give the best support to our client, we engaged engineers on different specialties which work together to obtain the best end results in an Agile methodology, using Cycle-V process and following ASPICE policies.

Results

  • Over 1600 tickets
  • Over 38 new developed features
  • 50% faster deployment due to proficiency with ramp-up and prioritize knowledge transfer.
  • 100% compliance with our client’s tools, standards, process and methodologies.
  • Taking over in record time the ownership on two major projects for our partner/client which allowed the client to focus on more pressing deliverables.
  • Zero delay due to facilitating a seamless transition process. In record time, we took the ownership on two major projects, allowing our client to focus on more pressing deliverables. At the same time, through our work we secured the projects’ stability & scalability.
