Senior Staff Firmware Engineer (ADAS Systems)
The ADAS Systems Group was tasked with development of the vehicle s autonomous hardware and software to meet ASIL product requirements in conformance with the ISO 26262 standard.Project: Development of the ADAS hardware and software of an electric, autonomous vehicle.Responsibilities: Primary responsibility involved developing firmware in support of an electric vehicle s ADAS module based on ISO 26262 safety design and verification requirements. Additional responsibility involved the design and development of the vehicle's ADAS health monitor to detect, report, and recover from system faults and failures. Additional responsibility included an associated project to explore the feasibility of replacing the current microcontroller with flash-based system in favor of an FPGA-based system which would provide a more flexible architecture while also offering a much lower latency fault recovery mechanism. Additional responsibility included the design and development of the vehicle's Event Data Recorder (EDR) using an adjustable data buffer to address global legal requirements. The EDR was designed to support both temporary and permanent partitions, recording both pre-crash data and unexpected operational events utilizing a back-end data storage system. Additional responsibility involved developing ADAS-related intellectual property through US and international patent applications. Eighteen patent applications have been submitted covering diverse topics including ADAS validation, adaptive safe-state management, and fault-tolerant diverse network between safety critical vehicle modules. To date, one patent has been granted (10608941). Additional responsibility included developing code in Matlab/Simulink on a dSPACE MicroAutoBox target system. Project goal was to develop the interface between a Matlab vehicle model and a Dataspeed drive-by-wire system over CAN, Ethernet, GPIO, PWM, and serial connections. Project also involved developing the UDP interface supporting the Applanix POS LV GPS & IMU positioning system. Deliverables were developed in support of the NIO EP9 project.
