Continental of Hanover is turning commercial vehicles into data carriers on wheels: In modern trucks (and buses), around 170 sensors record data, more than 90 electronic control units process the data, and roughly 150 actuators convert the data into mechanical movement. Thanks to the Internet, the data can be shared easily and external information can be added to them. Increased connectivity paves the way for new applications and services for handling performance, vehicle management, logistics and automated driving. The dynamic eHorizon, a sensor system that supplies vehicles with real-time information, is designed to create more savings and provide additional safety.
The sensor system in eHorizon uses topographical route data and a GPS signal to provide the control units in the vehicle with information about the route ahead. These then adapt the driving style and speed automatically. Continental is continuously developing this series product. The final stage of expansion, eHorizon, is designed to be a highly accurate information carrier that is always up to date. Thanks to real-time information, it even takes into account dynamic events such as weather, accidents or traffic jams.
If the data sources report a traffic jam, for example, the dynamic eHorizon forwards this information to the control units. These then prompt the vehicle to coast or shift down a gear. By providing this information in good time, the system not only saves fuel, but can prevent serious accidents by warning drivers of dangers they cannot yet see, such as the tail of a traffic jam around a bend.
Monitor Tire Pressure, Too
Low tire pressure often results in high operating costs for trucks. The day-to-day stress experienced by drivers often distracts them from keeping a constant eye on tire pressure. The ContiPressureCheck system can help. It uses sensors inside the tires to monitor the pressure and temperature of all tires on the vehicle continuously, during travel and in real time. The data are recorded constantly and shown to the driver on a display. If the tire pressure deviates from the nominal value, the system issues a warning immediately. This enables the driver to take instant measures to eliminate the problem and restore the tire pressure to the normal value.
The system therefore helps to reduce fuel consumption and tire wear while at the same time increasing the service life. With increased efficiency and a longer tire service life, the operating costs of the fleet are reduced. Thanks to a reduction in CO2 emissions, ContiPressureCheck also makes a positive contribution to sustainability. The continuous measurement of tire pressure also increases the safety of the vehicles, as it reduces the risk of a flat tire.
ContiPressureCheck is quick and easy to install and can also be retrofitted at a later point when the tires are changed. It is compatible with various telematics systems. It is integrated in the VDO TIS-Web fleet management software from Continental—a result of the successful collaboration between the Commercial Vehicles and Aftermarket divisions, responsible for commercial vehicle and trade activities at Continental, and Continental Commercial Vehicle Tires, the tire division for commercial vehicles. Fleet managers can see the tire pressure and temperature data directly on their screens. They can use this information to react proactively to tire pressure that is too low and consequently maintain the value of the carcass for the entire service life of the tire.
