eHorizon integrates topographical and digital map data with sensor data, namely GPS receivers, for predictive control of vehicle systems. Future events, such as the uphill incline after the next corner, are exploited at an early stage in order to optimize the vehicle's response. eHorizon interprets map and sensor data and automatically adapts the engine and transmission management.
eHorizon facilitates several other applications that make driving more efficient, safer, and more comfortable. An example of this is camera-based recognition of road signs. In this application, the eHorizon supplies information from additional signs such as weather-, vehicle-, and time-dependent speed instructions, which are not identified by the camera systems.
3% lower fuel consumption per truck, i.e. saving over 1,500 liters of fuel, or more than 2,000 euros, per year. In addition, 4.2 metric tons fewer CO2 emissions per truck per year. That is the success story so far of the predictive cruise control system "Scania Cruise Control with Active Prediction" provided by truck manufacturer Scania. At the heart of the system is the Continental eHorizon, which was made in close cooperation with "HERE," the provider of navigation maps and services.
The adaptive cruise control supplies the 3D profile of the driving route based on topographical map data, the digital map from HERE, and the GPS signal. The vehicle speed can then be automatically adjusted to the route ahead. Acceleration is applied just before an incline, optimally utilizing the available torque and requiring fewer gearshifts. Before a downhill gradient, the speed is reduced in order to utilize the vehicle's downhill acceleration as effectively as possible.
