AUMOVIO unveils its new braking system and receives first series order

Technology company AUMOVIO is unveiling the distributed brake system, the latest generation of its electrohydraulic brakes, delivering greater performance in a compact design. The first order from a major Chinese vehicle manufacturer has already been received, with production scheduled to start at the end of 2027.

The distributed brake combines an advanced one box brake with an Electronic Stability Control (ESC) system. It operates fully electronically from the brake pedal through to the fallback level and makes use of modern electrical/electronic (E/E) architectures. This allows the actuators to be designed smaller and lighter. The system frees up valuable installation space – for example, for a larger high-voltage battery – and enables more flexible actuator placement in the vehicle. At the same time, the distributed brake delivers greater performance than previous one box systems, making it particularly suitable for demanding applications such as highly automated driving.

“The mobility of the future is automated, electric, and increasingly based on new vehicle architectures. This transformation will not happen overnight, but step by step. With our solutions ranging from electrohydraulic to fully dry braking systems, our customers can draw on a very broad product portfolio. The new distributed brake system expands this portfolio even further. It gives our customers even greater flexibility, efficiency, and powerful performance. With its first series order, our new system is taking an important step toward high-volume production.” – Boris Mergell, Head of the Safety and Motion business area at AUMOVIO

For the distributed brake system, AUMOVIO leverages the E/E architecture of modern vehicles. It includes multiple power supply points and redundant electrical networks. Such architecture meets the requirements for braking systems without a hydraulic fallback, which must be equipped with a redundant system including its own electrical circuit. Since the driver’s braking commands are transmitted electrically and no hydraulic fallback with a mechanical connection to the driver is required, almost all braking system components – except for the electronic brake pedal – can be positioned freely in the front section of the vehicle. This flexibility supports new vehicle concepts and enables optimized use of installation space, for example using larger batteries that extend vehicle range. The distributed brake system is suitable for many different vehicle types, as not only fully electric and hybrid vehicles but also many new combustion-engine vehicles are equipped with such redundant E/E architectures.

The absence of a mechanical-hydraulic connection between the brake pedal and braking system provides further benefits for the distributed brake system. For example, the air gap between the brake disc and brake caliper can be increased because brake pressure in the fallback level is built up electronically with greater precision and speed than before. This reduces unwanted friction between the brake disc and brake caliper.

At the same time, a single e-pedal braking system can be used for a wide range of vehicle architectures. Instead of slightly different variants, for example for left- or right-hand drive, combustion-engine or electric vehicles, all vehicles can be equipped with the same e-pedal braking solution. This significantly reduces the number of variants and helps lower development, manufacturing, and logistics costs for both suppliers and car manufacturers.
