Brembo (Nanjing) Automobile Components Co., Ltd.

Product: SENSIFY 

Description

Unveiled in October 2021, SENSIFY is a new pioneering intelligent braking system and crystallizes Brembo’s cutting-edge research results in intelligent braking systems which it has been working on for more than 10 years. SENSIFY comes from the merge of two words: SENSE that is a faculty by which a human perceives an external signal and stimulus; and SIMPLIFY which means simplicity in installing at best the product in harmony with the vehicle. SENSIFY has evolved naturally from Brembo’s heritage and know-how. It combines the design of the best braking components with the integration of a digital brain and sensors, and is an electronic braking system with independent and wheel-distributed braking actuation. SENSIFY integrates the most advanced software based on artificial intelligence with Brembo’s world-renowned brake components. It combines the current Brembo product portfolio of calipers, discs and friction materials with digital technology and artificial intelligence to create a flexible and revolutionary platform that includes software, predictive algorithms and data management to control the brake system digitally, to customize brake response to drivers’ driving style, and to improve their experience on the road. SENSIFY constantly delivers driving pleasure and total safety. It is intuitive, responsive and smooth; it delivers the driver the expected performance when needed, combined with exceptional control. SENSIFY meets the market needs for more digital, electric and intelligent passenger cars, responds to government policies for energy saving, emission reduction and environment protection in the automotive industry, and is an innovative intelligent braking system with epoch-making significance.

Unique advantages

Compared to a traditional braking system, SENSIFY is an electronic braking system with independent and wheel-distributed braking actuation which, besides the smart management of NVH calibration, controls the braking force of each wheel independently according to the driver’s needs, vehicle dynamics and traffic conditions. SENSIFY strives to deliver brand-new driver experience and enables drivers to leverage their sensitivity. With SENSIFY the braking system is no longer simply a sum of its parts but an ecosystem, where artificial intelligence and software play an active role. Data collection is leveraged to improve the driver experience and allow the system to be constantly updated, with a view to creating value added for end users. SENSIFY is also a more sustainable braking solution. Thanks to the optimized braking action on each wheel combined with the absence of drag between pads and discs, dust emissions are minimized, range is increased, and battery size is reduced. Reducing drag torque will be one of the biggest contributors to reduce CO2. Lower brake temperature due to managing 4 independent corners will lower brake dust and wear. SENSIFY is eco-friendly due to the absence of brake fluid and fewer components and parts, and avoids the complications of bleeding the system, as well as storage. By braking, you regenerate energy into the battery. With SENSIFY, the regenerative braking is always at the top level under all driving conditions. SENSIFY offers great flexibility for OEMs’ chassis design. With fewer components and no brake fluid and brake lines, this solution is cost-effective and gives more space for chassis design. It features shorter development time and easier software integration with electric vehicles and fuel vehicles, thus covering all market segments including supercars, city cars and new commercial vehicles. Besides service braking functions, SENSIFY integrates advanced vehicle control functionalities related to the braking (e.g. EBD, ABS, ESC). Two ECUs read the driver’s brake request via sensors on the brake pedal. The front ECU controls two electro-hydraulic actuators, meanwhile the rear ECU controls two electro-mechanical calipers, integrating also the electric parking brake function.

Application

SENSIFY improves the performance of vehicles of all types. This distributed system has many benefits and applies to diverse vehicles and structures. It offers possibilities for vehicle design and great flexibility for carmakers. It realizes easier integration with electric and fuel vehicle platforms, covering all market segments including supercars, city cars and even new commercial vehicles.

Prospect

SENSIFY meets the market needs for more digital, electric and intelligent passenger cars, responds to government policies for energy saving, emission reduction and environment protection in the automotive industry, and is an innovative intelligent braking system with epoch-making significance. Once applied, SENSIFY will have profound implications for: 

1) The driver: • Adjusting brake response according to his/her driving style preferences since the traditional brake pedal feeling is guaranteed by a brake pedal simulator. • Greater safety and system stability, more controllable brake and vehicle posture in cornering. • Regenerative braking and energy recovery for an increased range. 

2) The carmaker: • Modular configuration, shorter development time and easier software integration for vehicle platforms. • Independent control of each wheel’s braking force and smart management of NVH calibration. • No brake fluid and brake lines, more flexible chassis design, and less vehicle manufacturing costs • Integrating advanced vehicle control functionalities related to the braking (e.g. EBD, ABS, ESC), and less braking components • Prospective technologies applicable to automatic drive 

3) The environment • Less drag torque, brake dust and CO2 emissions, increased life yet smaller size of battery. • No brake fluid and less environmental impact.
