How Protean Achieves MISRA Compliance for In-Wheel Motors Using Helix QAC

Protean Electric is an award-winning technology company that has developed an in-wheel electric drive system for hybrid, plug-in hybrid, and battery electric light-duty vehicles. Protean is headquartered in Detroit (Troy), with engineering and manufacturing operations in UK and China.

Protean Drive™ is a fully-integrated, direct-drive solution that combines in-wheel motors with an integrated inverter, control electronics, and software. Each motor fits into the unused space behind a conventional 18- to 24-inch wheel. And it can use the original equipment wheel bearing. The direct-drive configuration reduces part count, complexity, and cost.

Protean needs to comply with ISO 26262 and a coding standard. And they comply by using Helix QAC for C and C++.

How Helix QAC Helps Protean...


Comply With ISO 26262

Control MISRA Rule Deviations

Avoid False Negatives

Helix QAC finds issues other tools miss.

"We're impressed by the performance of Helix QAC. It is very accurate. It finds issues that other tools have missed."

The Need For ISO 26262 Compliance

Protean Electric needs to comply with ISO 26262. A key part of ISO 26262 is managing hazards and risk through ASIL. And ISO 26262 requires a coding standard, such as MISRA.

To achieve compliance, Protean needs a tool that:

  • Provides flexibility (and control) over MISRA deviations.
  • Delivers accurate static analysis (without false negatives). 
  • Is pre-certified for ISO 26262.

Protean found it with Helix QAC

Helix QAC Ensures Compliance for In-Wheel Motors

Protean has experience with a number of static analyzers and MISRA checkers. And not all tools are the same.

They selected Helix QAC with the MISRA C:2012 compliance module for:

  • Control over rule deviations.
  • Accurate static analysis (without false negatives).
  • Pre-certification as an ISO 26262 development tool.

“We are impressed by the performance of QAC. It is very accurate and it finds issues that other tools have missed. We are particularly conscious of the dangers of false negatives and the false sense of confidence that can be created when tools fail to detect genuine issues."

— Huw Jones, Senior Software Test Engineer at Protean
