Bosch works hard on new teams referring to security, as is the case with its novelty electronic cable brake system. During six days, along 3,300 kilometers and crossing different climatic zones to the Arctic Polar Circle, a driving test has been carried out to test the traffic this new Bosch cable brake system. Which distinguishes the cable brake system.
This solution completely eliminates the mechanical connection between the brake pedal and the system itself. The driver’s braking application is transmitted to the cable brake system by electrical signal through redundant signal lines. For this, Bosch uses two independent hydraulic brake actuators: a cable brake actuator and a ESP. Current brake systems, such as Bosch’s integrated servofrane, still guarantee the necessary redundancy in case of fault through a mechanical connection with the brake pedal.
However, this coupling, through an entrance bar to the brake pedal, is removed in the new Bosch electronic cable brake solution. Everything indicates that this cable brake system be officially launched next autumn. In addition to the hydraulic solution, the German brand is also developing a purely electromechanical system. The company has already received orders from several manufacturers in the automotive sector and He hopes that, from here to 2030, more than 5.5 million vehicles worldwide are equipped with cable braking.
Bosch electronic cable brake system in detail
Undoubtedly, one of the advantages of this electronic cable brake system is its facility ease. Thanks to the suppression of the mechanical connection, the system components can be installed where it is more optimal in terms of security in case of collision, noise, vibration and manufacturing. Flexibility when choosing where to install brake actuators helps avoid the need for different variants for vehicles with right -wing flying and left.
Within the automobile world, where it is initially intended, this cable brake system allows new pedal concepts with a significantly shorter brake pedal route to create space for new interior designs. Bosch’s BY-WIRE hydraulic brake solution is based on the proven brake system technology and is a combination of a By-Wire brake actuator and an ESP.
Its thin design saves installation space and reduces the weight of the brake system. Since both the By-Wire brake actuator and the ESP are assigned to different channels of the electrical system, each can independently generate the necessary braking pressure in the four wheels brakes in case of breakdown. Therefore, this Bosch solution is also suitable for highly automated vehicles, since it meets the protection of the brake system required for safety reasons.
If we focus on the world of two wheels we already saw how Bosch made us known the new ECBS braking system that mounts the new Ducati Panigale V4 2025. A technology that combines advanced electronic and braking systems and that promises to significantly improve the braking In circuit.
Returning to the new cable braking system, this is being developed at the Bosch Technology Center in Abstatt, near Heilbronn. The development team toured a long journey from southwest Germany, through Hamburg, Copenhagen and Stock North of Sweden.
Bosch specifically requested and obtained the approval for the use in the public road of the test vehicle in several countries, based on a broad concept of security. Hagen Kuckertproject director of the Bosch cable brake actuator in ABSTATT, he commented on this dynamic test:
“The whole team has worked for this event with incredible motivation and is very proud of this achievement. Our cable braking hydraulic system has worked perfectly on the trip. With our first long distance test we have shown in an impressive way that we can carry a real cable brake system from the test track to the road in a safe and successful way. ”
Concludes: “During the trip we have made thousands of braking, we have been able to obtain important information and data on the behavior of the brake system in a wide variety of traffic situations and compare them with our previous simulations. All this is incorporated into the subsequent development work to further optimize our hydraulic cable brake system. ”
Now it’s time to ask if the cable braking system will reach the two wheel world and if so, when it will.
