Simulating Concept Ideas

A common procedure is to evaluate concept ideas at an early stage by simulation on a PC. This requires not only function models but also suitable road models. The vehicle behavior, road and surrounding traffic can all be created with models from the dSPACE Automotive Simulation Models (ASM) tool suite. The simulation can be based on real roads. For the electronic horizon, there is the dSPACE ADAS RP Blockset (NAVTEQ Interface). MotionDesk supplements the dSPACE tool chain and visualizes the movement of mechanical objects in the 3-D world.

Function Development in the Vehicle

Simulation alone is not enough. It is also necessary to experience driver assistance functions and modify the algorithms in a real vehicle. With the flexible dSPACE prototyping systems, you can optimize the control designs for the real ECU as often as you need until they meet your requirements. Block diagram designs are automatically implemented on the system and calculated in real time. With its additional Embedded PC, MicroAutoBox II uses digital road maps to compute the electronic horizon and preprocesses video data. You can connect HMIs and implement WLAN or mobile communications applications.
Dedicated blocksets are available for linking to special tools. For example, the dSPACE ADAS RP Blockset (NAVTEQ Interface) and the ADASIS v2 HR Blockset to provide the electronic horizon, and the dSPACE ADTF Blockset to connect to the EB ADTF Assist. The Programmable Generic Interface connects sensors and actuators via serial interfaces such as SPI or I²C.

ECU Autocoding

When production code is generated with dSPACE TargetLink^®, the specified functions are transferred to production C code and then implemented on the ECU. This considerably reduces the time needed for coding and development, while also increasing the quality of the production code. Advanced driver assistance systems prevent collisions with other road users by intervening autonomously in the vehicle's longitudinal and lateral movement. They are therefore treated as safety-relevant electronic systems. German safety standards authority TÜV SÜD has confirmed that TargetLink is suitable for the development of safety-relevant systems.

HIL Testing

The complexity of today's ECU software requires thorough ECU tests. dSPACE's simulation software and hardware covers each and every conceivable test scenario, ranging from testing single ECUs to integration testing of entire networks. HIL tests require suitable road models. Here too, the dSPACE Automotive Simulation Models (ASM) tool suite contains models for the vehicle behavior, road and surrounding traffic. The HIL simulation can be based on real roads. The electronic horizon is obtained by using the dSPACE ADAS RP Blockset (NAVTEQ Interface), and the HIL simulator can be coupled with EB Assist ADTF quickly and simply via the dSPACE ADTF Blockset.
To emulate sensor data, such as data from the torque rate sensor integrated in the ECU under test, the Programmable Generic Interface is used.

Ethernet Interfaces

To develop and test driver assistance ECUs, dSPACE's real-time platforms increasingly need to be connected to third-party systems via Ethernet. There are powerful options available for this in a range of application areas (Ethernet interfaces).

GPS Interfaces

dSPACE has several different options for connecting GPS sensors. Receiving GPS Data with the MicroAutoBox provides an example implementation showing the reception of GPS data on the MicroAutoBox via the NMEA-0183 protocol. CAN-based GPS sensors can be connected in a similar way. The necessary USB devices can be connected via MicroAutoBox II with Embedded PC.
