New Safer and Reliable Electronic Module Enhancing Autonomous-Vehicle-Market Demand

Posted On December 11, 2020     

Autonomous cars, also known as self-driving cars require minimum human vigilance once the destination is selected.  Many expect that they would capture the future market due to their inherent benefits. Recently, ADAC, a German Motoring Organization also predicted that by the year 2050, about 70% of all new vehicles will have the ability to self-drive while freeing drivers to do some other tasks while driving.

Self-driven cars have two power sources, mainly, a high voltage battery and a conventional 12-volt battery that supplies power to the vehicle when it is in a high–load situation. Systems critical for a driver’s safety like brakes and steering can be connected to these two powerhouses. However, when a fault occurs in a particular area in these vehicles, that area becomes isolated by means of an overload protection system.

 In order to counter this problem researchers have collaborated on the project HiBord, to develop an electronic disconnect device that will be able to isolate any faults that occur in the vehicle’s electric systems. This module was tested in a BMW i3 and the test results came out to be quite successful.

Electrical Systems that are available in the market today for automated cars have duplicate onboard electrical systems in case a shut down occurs, however, this practice increases the weight of the system as well as, it is more expensive. In the HiBord project, researchers developed a disconnect device that although shuts of components at fault still safeguards enough power supply to make safety-critical components work. This ensures safe driving without needing another onboard electrical system.

In present systems, if any car is under-voltage in the middle of driving it may trigger an uncontrollable failure of the entire onboard electronics including safety–critical ones like break and steering systems. This poses a great threat, especially to high-speed cars. Hence, the newly developed model will provide the ability to secure the passengers of a car by bringing them to an emergency lane of the freeway or a parking lot if a fault occurs in the car.

This technology is a feat in the development of the Autonomous Vehicle Market as it is designed in a manner that it can be used in any electric vehicle. It has the ability to provide a safer and more reliable way of driving and is way better than the conventional electrical systems.
