Interior designers also may feel inspired. This becomes apparent when, for example, a digital display is printed on a natural surface such as a wood veneer without a conventional screen. In the future, it will also be possible to integrate solar panels into the car without increasing weight. The renewable energy generated by the sun can then be used to recharge the battery.
To design the new systems, a part is first implemented in a CAD system. The electronic circuit - which was previously wired in a conventional control unit using conventional methods - is then printed onto the flat surface and the components are virtually assembled before the CAD representation is returned to the 3D original. The part, including the electronics printed on the surface, is now ready for series production.
Jaguar Land Rover has tested LESA technology on a prototype overhead control panel. In addition to the weight savings mentioned above, the thickness has been reduced from 50 to just 3.5 millimetres.
Ashutosh Tomar, Electric Research Technical Manager at Jaguar Land Rover, is convinced that LESA represents the future of automotive electronics. “This will enable us to develop and manufacture innovative, flexible and customizable interiors for our customers and save weight and production costs," says the JLR visionary.
