Bosch at IAA 2025: Driving the future with Software-Defined Vehicles and Electromobility Solutions
bosch is showcasing a range of software and hardware innovations at IAA 2025, focused on accelerating the development of advanced driver-assistance systems, streamlining vehicle architecture, and advancing electromobility. the company is emphasizing a shift towards centralized computing and “act-by-wire” technology, alongside continued investment in both combustion engine and electric powertrain solutions.
bosch’s advancements in AI end-to-end architecture are designed to speed up development and enhance the precision of driver and parking assistance systems, currently reaching up to SAE Level 2 automation. This architecture has already seen adoption by several vehicle manufacturers, particularly in the Chinese market, in both Range and Premium versions.
Supporting these systems, Bosch is introducing a new generation of sensors. these include low-cost multifunction cameras,SX600 radar sensors,and SX601 radar sensors boasting a 30% increase in range compared to previous models. New MEMS sensors are also being unveiled, capable of concurrently providing data to multiple vehicle systems. Further sensor innovation comes in the form of the TB293 and TB193 ultrasound chips, designed to set new standards for data transmission speed.
Beyond sensors, Bosch is presenting the SMP290 pressure sensor with integrated Bluetooth technology, aiming to simplify vehicle architecture and enable new features, including a minor damage detection system. This system can record impacts and micro-collisions and receive remote updates.
A key focus for Bosch is the move towards centralized vehicle architectures. The company is developing scalable infrastructures based on a few high-performance computers, intended to replace dozens of traditional control units, reducing complexity and wiring. These systems will be supported by 48V networks for stable power supply and over-the-air software updates.
Bosch is also heavily invested in act-by-wire technology,eliminating mechanical connections between driver commands and vehicle actuators. The brake-by-wire solution is already slated for series production and represents a significant step towards customizable driving dynamics. Bosch software manages a thorough suite of actuators under the umbrella of Vehicle Motion Management,synchronizing brakes,steering,chassis,and propulsion. This allows for dynamic vehicle character adjustments, transforming a car into an agile city vehicle, a high-performance sports car, or a luxury sedan, and includes features like “comfort stop” which aims to reduce car sickness by up to 90%.
In the realm of powertrains, Bosch is maintaining a technologically neutral approach, offering solutions for both internal combustion engines and electric vehicles. Significant attention is being given to silicon carbide (SiC) semiconductors, crucial for the efficiency of electric mobility, available in versions up to 1200 volts.
The e-axle 3-in-1, oil-cooled, integrates the motor, power electronics, and transmission into a single, compact unit. New generations of bidirectional inverters and converters are also being introduced, enabling electric vehicles to function as mobile energy storage units.Software solutions like eAxle Heating are designed to optimize battery temperature and reduce charging times, while advanced thermal management systems utilize refrigerants like propane R290 to maximize efficiency.
