This paper presents the hardware design and implementation of the in-vehicle system (IVS) for the European Union (EU) emergency call (eCall) system. Modules of the IVS are developed and implemented on a field programmable gate array (FPGA) device. The modules are simulated, synthesized, and optimized to be loaded on a reconfigurable device as a system-on-chip (SoC) for the IVS electronic device. Benchtop test is completed for testing and verification of the developed modules. The hardware architecture and interfaces are discussed. The IVS signal processing time is analyzed for multiple frequencies. A range of appropriate frequency and two hardware interfaces are proposed. A state-of-the-art FPGA design is employed as a first implementation approach for the IVS prototyping platform. This work can be used as an initial step to implement all the modules of the IVS on a single SoC chip.

“…As soon as the MSD is received by the PSAP, a feedback message is sent by the PSAP to acknowledge of receiving the MSD. The IVS activates the data link and voice channel between the vehicle automatically or manually through a button [6] [7].…”

“…The transmitter employs a modulator to modulate the encoded MSD in a Bipolar Pulse Position Modulation (BPPM) system [7]. The IVS transmitter needs the interface solutions to read the MSD data from the vehicle and to transmit the modulated signal via the GSM module.…”

This paper presents embedded system design of the In-Vehicle System (IVS) for the European Union (EU) emergency call (eCall) system. The IVS transmitter modules are designed, developed and implemented on a field programmable gate array (FPGA) device. The modules are simulated, synthesized, and optimized to be loaded on a reconfigurable device as a system-on-chip (SoC) for the IVS electronic device. All the modules of the transmitter are designed as a single embedded module. The bench-top test is completed for testing and verification of the developed modules. The hardware architecture and interfaces are discussed. The IVS signal processing time is analyzed for multiple frequencies. A range of appropriate frequency and two hardware interfaces are proposed. A state-of-the-art FPGA design is employed as a first implementation approach for the IVS prototyping platform. This work is used as an initial step to implement all the modules of the IVS on a single SoC chip.
