Streamlining Product Development
MAD MUTT is an Automotive Functional Development Platform dedicated to increasing the efficiency of product creation.
Some of MAD MUTT's attributes include:
○ Customizable mobile MiL/SiL/HiL product development platform;
○ Real-time remote controlled by both Virtual and Human drivers;
• E.g. IPG Carmaker SW + Xpack4 or Real driving simulation setup + PC;
○ Streamlined development of ADAS features (SW and HW);
○ 10 to 30% of the cost of a prototype vehicle;
○ Reusable on any number of vehicle programmes;
○ 48V architecture - easy to operate - safe - low maintenance;
○ Real-world testing time can be automatically accumulated without human interaction;
○ Data is automatically processed to validate correct functionality;
○ Practical assessment of new feature value add ahead of programme start;
Why MAD MUTT?
• Limited access to prototype vehicles forces single-point integration:
○ Multiple concurrent issues found - complex root causes;
○ Large time gap between development and validation - poor understanding and developmental delays;
○ Limited time available on the vehicle - hard to diagnose and fix real issues;
• Constantly varying maturity and unknown state of prototype vehicles:
○ Constant rework and maintenance time required - development delays and undiagnosed issues;
○ Poor understanding of vehicle's initial state - hard to diagnose and fix real issues;
• Varying fidelity requirements by different teams:
○ Unnecessary high complexity - time lost understanding vehicle state and fixing unrelated issues;
○ High maintenance needs - constant updates required;
○ Incompatibility across the business - one "size" does not fit all;
• Static HiL testing fails to exercise multiple physical operating points:
○ Limited by the amount and quality of the data;
○ Limited by the scope of test cases;
• Simple simulation only accounts for an array of single, linear operating conditions:
○ Component and system behavior is not fully captured - true error states are missed.
Simple Flexibility in System Development
• Assess the value add of prospective features quickly and easily:
○ Develop high-level SW and immediately verify its function on a real working vehicle;
○ Select key features by performing real-world t model in the loop testing before the start of programme;
○ Create well informed, SMART requirements that reflect the real needs of the product;
• Control Product Quality from the start:
○ Verify the function of all features in isolation as soon as the SW and/or HW become available;
○ Gradually integrate different features and interfaces without low-level coding;
○ Verify the correct functionality of all system-level interfaces early on;
○ Tune the system requirements based on learning activities;
○ Develop better simulation models at an early stage using collected data;
• Create complex and repeatable test cases:
○ Step by step system validation with the appropriate level of fidelity;
○ Test real-world nuisance scenarios between human drivers Vs. ADAS and self-driving systems without risk;
○ Use virtual drivers to ensure accurate test repeatability;
○ Calibrate remotely and in real-time;
○ Understand and tune system behavior by changing single parameters after each test case;
○ Reduce the number of prototype vehicles required;
○ Test system durability and resilience to different noise factors with minimal human interaction;
