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;

How does MAD MUTT work?

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.

What it offers

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;
