RapidiTTy™ Adaptive Cruise-Control Test Facility from TTE Systems
The RapidiTTy™ Adaptive Cruise-Control Test Facility incorporates 10 embedded processors (LPC2378), linked by dual CAN bus: it reproduces the system architecture involved in an adaptive-cruise control (ACC) design for a passenger car.
Using the RapidiTTy™ Adaptive Cruise-Control Test Facility, developers can investigate the impact of different design and implementation decisions on the performance of a typical embedded control system: for example, this testbed can be used to investigate the use of different processors, different network architectures and different control algorithms on vehicle performance or fuel economy.
The RapidiTTy™ Adaptive Cruise-Control Test Facility runs test scripts (without user interaction) to support long periods of system testing: during the test period, the hardware-in-the-loop (HIL) testbed allows the injection of faults (for example, reproducing the impact of electromagnetic interference on one or more processor nodes) and records the system response in detail.
Please note that:
- The LPC2378 software used in the RapidiTTy™ ACC Test Facility was created using RapidiTTy™ MCU.
- The PC software used in the RapidiTTy™ ACC Test Facility was created using RapidiTTy™ x86.

Alternative designs for the ACC system
The RapidiTTy™ Adaptive Cruise Control Test Facility is a script-based HIL system which is designed to run over long periods, without user intervention.
Different versions of this system can be produced to match customer requirements (using, for example, different processors, different numbers of processors or different control algorithms).
Please contact us to discuss your ideas. If we can meet your requirements, we will provide a detail quotation.
