New Bosch Electronic Braking System Reduces Weight and Space, Increasing Efficiency and Range of Electric Cars.
Bosch has completed public road testing of a technology that can transform sustainable mobility. It is the brake-by-wire system, which eliminates the mechanical connection between the pedal and the braking system. This reduces weight and installation space, factors that can increase the range of electric vehicles.
The tests took place in different climatic zones, totaling 3,300 kilometers traveled. In just six days, the Bosch team reached the Arctic Circle driving a Nissan Ariya, validating the efficiency and robustness of the system. This technology promises to be a game changer in the automotive market.
Innovative Functioning of the Electronic Brake
Bosch’s brake-by-wire system replaces the traditional hydraulic and mechanical link with electrical signals. When pressing the brake pedal, the driver sends an electrical command to a remote actuator (a device that converts a control signal into linear or rotary mechanical movement to perform a specific action).

This actuator then moves the brake pads against the disc, promoting braking. The absence of components like hoses and fluid reservoirs brings direct benefits.
Besides simplifying the system, this electronic approach significantly reduces the vehicle’s weight. This aspect is vital for electric vehicles, where every kilogram less can mean a greater range on a single charge.
Bosch estimates that by 2030, over 5.5 million vehicles worldwide will be equipped with this technology.
Advantages of This Brake for Electric Vehicles
The main advantage of brake-by-wire is the reduction in energy consumption. Electric cars, which rely solely on batteries, benefit from every element that increases energy efficiency. With a lighter braking system, vehicles can cover greater distances without recharging.
Additionally, the space freed up by the absence of hydraulic components allows for more compact and aerodynamic designs. This paves the way for innovations in automotive design, improving ergonomics and interior comfort.
Guaranteed Safety and Reliability
Bosch’s braking system was developed with a focus on safety. It features two independent hydraulic actuators: one by-wire and the other integrated with the electronic stability program (ESP).
In case of a failure, both actuators can independently increase the braking pressure. This electronic redundancy eliminates risks associated with common mechanical failures in conventional systems.
This robust configuration is essential, especially for highly automated vehicles. By ensuring that braking can be controlled in any situation, the system positions itself as a reliable solution for the future of mobility.
Flexible Design and Optimized Space
Another important differentiator of brake-by-wire is the flexibility in vehicle design. As the actuators do not need to be positioned on the fire wall, manufacturers have the freedom to place them strategically. This can reduce noise and vibrations, as well as improve safety.
The system also frees up space in the cabin. Bosch is working on new pedal designs, such as a braking control pad.
In this model, the driver presses a platform instead of a traditional pedal. Integrated sensors transmit the electrical signal to the system, optimizing response and reducing the effort required to brake.
This flexibility also facilitates the production of vehicles with right-hand and left-hand steering, simplifying manufacturing processes for different markets.
Impact on Sustainability and Future Applications
The brake-by-wire technology is not limited to passenger cars. It can also bring benefits to public transport, cargo trucks, and industrial fleets. Weight reduction and simplified maintenance increase energy efficiency and contribute to sustainability.
However, despite the potential, the application of the system in motorcycles remains uncertain. Experts question its reliability in extreme conditions. Motorcycles face intense vibrations and adverse conditions, which may require additional backup systems to ensure safety.
Launch and Prospects
Bosch’s brake-by-wire system represents a milestone for the automotive industry. Its innovative design enhances energy efficiency, reduces weight, and optimizes internal space.
With a launch scheduled for the last quarter of the year, the technology promises to accelerate the adoption of electric and autonomous vehicles.
Its benefits in safety, design flexibility, and positive impact on sustainability position the system as an essential solution for the future of mobility.
With millions of vehicles expected to adopt this technology by 2030, Bosch may have taken a definitive step toward a more eco-friendly and efficient transport system.
