Energy is neither created nor destroyed, only transformed, enunciated the French chemist Antoine Lavoisier. With this premise Volvo wondered how to harness the kinetic energy released when braking the vehicle and becomes heat Is it possible to convert it into another type of energy?
Apparently yes, through the new system I-See. I-See harnesses the kinetic energy of the truck itself to "push" the vehicle when climbing slopes. Declines in the same energy is used to accelerate.
With the kinetic energy can save fuel 5%
The I-See system is linked to the tilt sensor gearbox and digitally obtained information about the topography. The fact that the system does not depend on the maps makes it more reliable, because you always get the latest information. The I-See system can record in a pending 4.000 5.000 kilometers distance.
"I-See is an autopilot that is linked to the cruise control the truck, takes over the gearshift, throttle and braking on slopes, to ensure that everything works the way that contributes to low consumption. I-See active neutral as possible, so that in certain stretches of road no fuel is not used at all, "says Hayder Wokil, product manager at Volvo Trucks.
"This way you can reduce fuel consumption by up to 5%. This figure is based on the results of simulations and tests on public roads. I-See requires the use of cruise control, and we know that the average driver This programmer uses about half the time. truck For normal operation, you scroll 140.000 kilometers a year, the savings will be 1.000 liters of fuel per year. This is a big difference to the profitability of transport companies " Wokil Hayder says.
The maximum effect on small slopes
I-See holding six different operations to get the maximum kinetic energy. For example, I-See accelerates increases, maintains a high gear and put everything in neutral declines to take the weight of the truck and drive motor.
"I-See works best in undulating terrain. In moderately long and steep slopes, I-See ensures that you can go long distances in neutral without using the engine, "explains Anders Eriksson, who was responsible for the development of I-See.
"His ability to go into neutral is what makes the system so special," he adds. When the truck runs in neutral, virtually no fuel used. But a lot of data to move in neutral, are needed. "It requires incredible precision. For example, it is necessary to know if the speed is reduced or increased by the following road section. A slope with a low gradient may be the deciding factor," says Anders Eriksson.
Other factors that make a difference are the aerodynamic drag and the weight of the truck. All told, the system has to follow and process a lot of information.
"I-See imitates the driving style of good drivers. Using the vehicle's kinetic energy, accelerate at the right time and avoid unnecessary shifting up, "says Hayder Wokil, who continues," but unlike a driver, I-See never gets tired, it's like an autopilot " .
This allows the driver to focus more on the surrounding traffic and other aspects of the trip. Even more, follow the road is more relaxed.
