DEWE-xxx-CAPS ... to test driver assistance systems
The DEWETRON CAPS series instruments are made for any dynamic test of vehicles 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.
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.
DEWETRON CAPS instruments are a safe investment! Due to their modularity they can grow with future applications.
