Exemplary use cases for RapidPro systems

  

In this scenario, automotive sensors and actuators are adapted to a dSPACE prototyping system with the help of the RapidPro SC Unit and the RapidPro Power Unit.

Signal Conditioning and Power Stages for dSPACE Prototyping Systems

The RapidPro SC Unit and the RapidPro Power Unit (equipped with the relevant SC and PS modules) can be used as separate units in conjunction with prototyping systems (MicroAutoBox, MicroLabBox, modular hardware including DS1005, DS1006 and DS1007 plus I/O boards, single-board hardware). The RapidPro SC Unit supports your prototyping system wherever demanding signal conditioning tasks such as signal protection, amplification, attenuation, filtering, and electrical isolation have to be performed. In turn, actuators like drives, valves, injectors, lamps, and relays require high current and/or high voltage output drivers. The RapidPro Power Unit provides your prototyping system with the necessary power stages. By using dSPACE‘s ConfigurationDesk® software, you can easily configure the SC and PS modules and generate a pinout description.

In this scenario, two RapidPro units form a stack including signal conditioning and power stages, so that complex I/O signals can be acquired and generated independently of the main CPU of the prototyping system.

Intelligent I/O Subsystems for dSPACE Prototyping Systems

Applications such as engine management need to acquire complex I/O signals, for example, for crankshaft and camshaft positions, and to generate complex signals for ignition and injection independently of the RCP system’s main processor and the model’s simulation step size. Offloading specific, time-critical tasks like these to a dedicated microcontroller decisively reduces the main processor’s load. The RapidPro Control Unit variant with MPC565 is used in this scenario as a slave microcontroller to extend existing prototyping systems with additional I/O functionality. The RapidPro Control Unit variant can be used together with MicroAutoBox or a modular DS1005- or a DS1007-based system (with DS4121 ECU Interface Board) and can additionally be combined with other RapidPro units. An integrated unit connection bus (UCB) lets you internally connect several RapidPro SC or Power Units directly to the Control Unit without external wiring. Communication between the RapidPro Control Unit and the prototyping system is performed via a high-speed link. An RTI RapidPro Control Unit Blockset for Simulink is available for graphical I/O integration and configuration as known from MicroAutoBox or modular hardware. Additionally, dSPACE‘s ConfigurationDesk provides an intuitive configuration of the SC and PS modules and diagnostics handling. In this use scenario, the RapidPro hardware can be used for developing co ntrol applications in fields such as engine, transmissions, chassis, body, and drives control.
