Combined Active Passive Safety Instruments (DEWE-CAPS)
Predefined Standard Models
DEWETRON CAPS series instruments are made for dynamic vehicle test where precise position information is required. All dynamic movements such as acceleration, speed, position, turning speed and angle of the vehicle are measured synchronously to analog sensors, counters, CAN bus and video data.
There are a lot of applications such as ADAS (Advanced Driver Assistance System) testing, LDW (Lane Departure Warning), functional safety testing, etc. where very accurate position information (down to 2 cm possible!) is needed.

Key Features
- Precise position, angle, distance, speed and heading information is recorded fully synchronized together with analog, counter, CAN bus and video data
- High accurate combined GPS and Gyro measurement
- INS/GPS system from GeneSys for six degree of freedom motion analysis
- High performance differential GPS position measurement
- GPS synchronized measurements from 2 vehicles with online data transfer
- Easy mounting, setup, alignment and calibration
- Comparable and reproducible tests
- Automated report generation for predefined maneuvers
- Safe investment, all systems can grow with future applications
Key Application: ACC (Adaptive Cruise Control)
One typical application is to test longitudinal control systems such as ACC (Adaptive Cruise Control). These measurements are usually performed with two or more vehicles. Each vehicle is equipped with a DEWETRON CAPS instrument and a GeneSys ADMA GPS/INS system. The communication link between each vehicle is WLAN. The DEWETRON data acquisition unit synchronously records the CAN data from the ADMA GPS/INS system and vehicles, together with data from optional digital and analog sensors and video images of the driver.
The key parameters for testing longitudinal control systems such as ACC include the relative position, the relative velocity and the relative heading between the leading car and the hunting car. (The ACC system to be analyzed is in operation in the hunting car.) There are also further parameters that are relevant, such as acceleration, velocity, 3D track data, corner radius and the precise time reference. Captured video data should simultaneously be available to check the driver status as well as the environmental conditions. Perfect synchronization of data is essential to reach the required accuracies for relative position.
