Considering the potential risks due to failure of electronic system of the dual-motor hybrid electric powertrain, this paper proposed a functional safety concept following the ISO 26262 standard. Firstly, the configuration and operation mode of the dual-motor hybrid powertrain was introduced. Next, based on the functional safety standard, potential hazards were analyzed and risks integrity level was assessed, then a functional safety concept has been designed taking account of the current developing capability of domestic powertrain suppliers, and finally functional safety requirements of vehicle controller unit which mainly responsible for the whole vehicle safety were developed.
