EV Vehicle Control Unit (VCU) & Software Architecture

Description

This EV Vehicle Control Unit eBook from 3D-LABS is written for engineers and students who want a clear, practical reference they can apply immediately.

EV Vehicle Control Unit (VCU) & Software Architecture is a practitioner-level engineering book covering the design of the vehicle control unit that sits at the centre of an electric powertrain — its hardware, its software architecture, and the functional-safety case behind it. It treats ASIL decomposition, AUTOSAR layering, torque-path safety monitoring and the verification evidence an OEM must produce before a VCU goes into a production vehicle.

What format does this book follow and what standards does it reference?

The book follows the V-model: requirements and hazard analysis down the left side, unit through vehicle verification up the right. Standards referenced include ISO 26262:2018 Parts 3–6 (concept, system, hardware and software development), AUTOSAR Classic Platform layered architecture, MISRA C:2012 coding rules, and ISO/SAE 21434 for cybersecurity engineering. Every work product is named with the clause that requires it.

How does the book treat hazard analysis and ASIL assignment?

HARA is worked through for a real set of EV hazards — unintended acceleration, loss of propulsion, failure to de-energise, incorrect regenerative torque — with severity, exposure and controllability argued rather than asserted. The book then shows ASIL decomposition across independent channels, the freedom-from-interference argument that makes decomposition valid, and where decomposition is commonly claimed but not actually justified.

What does the torque-path safety architecture look like?

The three-level monitoring concept is developed in full: level one computes requested torque, level two independently plausibilises it against pedal, speed and gear state, and level three verifies that level two is itself running correctly on independent hardware. The book gives the plausibility windows, the reaction times, the safe-state definitions, and the watchdog and question-answer handshake between the main core and the monitoring unit.

How is the AUTOSAR software architecture organised for an EV VCU?

Layering is covered from MCAL up through the basic software, the RTE and the application layer, with the EV-specific software components — torque coordinator, thermal manager, charge manager, HV contactor state machine — mapped onto it. The book covers runnable-to-task mapping, timing budgets, inter-ECU signalling over CAN, and the calibration and diagnostic interfaces the development team will depend on.
