Automotive manufacturers are increasingly asking tier-one suppliers to deliver components developed in compliance with ISO 26262, the international functional safety standard for road vehicles. This standard covers functional safety aspects of the complete development process, including design, implementation, and verification. Many manufacturers also want their suppliers to comply with AUTOSAR standards for ECU software architectures.
LG Electronics develops ISO 26262– and AUTOSAR-compliant software for the inverter systems used to drive electric and hybrid vehicle motors using Model-Based Design with MATLAB® and Simulink®.
“Our initial objective in adopting Model-Based Design was to meet ISO 26262 recommendations,” says Jeongwon Sohn, principal research engineer at LG Electronics. “We soon discovered additional benefits to using MATLAB and Simulink, including improved communication of technical design details between engineers in disparate fields, which has led to a reduction in software defects.”
