DARC (Data Radio Channel):A digital data transmission method using FM radio that is compatible with RDS andoffers a higher bit rate (10 kbits/s)DATEX (Data Exchange Network):Agreement between European traffic centres to exchange traffic and travel informationDead reckoning:A technique that calculates the current location of a vehicle by measuring the distanceand direction that the vehicle has travelled since leaving a known starting pointDG eCall:Driving Group on eCall under the eSafety ForumDGPS:Differential global positioning systems, a means of improving GPS auccuracy by using asignal from a fixed reference location.Digital Tachograph:An electronic system fitted to commercial vehicles to record driver information anddetails about driving time and distanceDriver monitoring:Observation of the driver’s condition and way of controlling the vehicle and theevaluation of possible deviation from the driver’s normal behaviourDSRC (Dedicated Short Range Communication):Standard enabling data transmission at a frequency of 5.8 GHzDVSMS (Dynamic Vehicle Safety Management System):By helping drivers avoid accidents, these systems help reduce fatigue and stress, allowingthe driver to feel more confident and in control. So, by integrating or enhancing existingactive steering, braking and suspension systems, DVSMS performs at a higher level thantoday’s brake-based stability systems. The future vision of DVSMS includes vehicledynamics sensor integration with active chassis controls. When coupled with our DriverStatePage 478 of 490
