BBW system is activated simply by pushing the brake pedal like a standard brake system.
The pedal simulator provides a pedal feel simiilar to a traditional brake system.
Its setting (force, stroke, damping, free-play) can be adjusted according to customer specification, with no influence to the rest of the system.
The pedal sensor detects the position of the pedal and relays it to the BCU.
The BCU processes the signal received by the pedal sensor, calculates the braking torque targets to each braking corner and relays it to the actuators.
Two versions 12V-48V
The front and the rear BCUs process the signal received by the pedal and relays it to actuators and electromechanical calipers.
The electro-hydraulic actuator, controlled by the BCU, converts electrical energy from the battery to the hydraulic pressure according to the pressure target.
BLDC 12V or 48V
The electromechanical brake caliper, controlled by the BCU, converts electrical energy from the battery to clamping force according to the force target. It also provides electronic parking brake function.
BLDC 12V or 48V
Reduction of braking distance
Compared to a traditional braking system, the BBW enables a remarking reduction of braking distance thanks to faster response time, especially for assisted or automatic braking functions.
Ability to tune the braking torque
The driver can choose between different braking settings (sport, comfort,…) according to personal preferences.
Ability to tune the pedal feel that the driver experiences
The driver can choose between pedal responses (soft, hard,…) according to personal preferences.
Steady braking regardless of the vehicle’s load
The braking torque automatically adapts to vehicle load, keeping braking distance constant.
CO₂ emission reduction
The BBW systems reduces CO₂ emissions, automatically optimizing the usage of the braking system and the energy recovery and reducing the brake residual drag.
Passage from service to regenerative braking is seamless and so the driver pedal feel isn’t affected. The pedal feel is not affected even during ABS modulation.
Flexible and modular layout
The BBW system is adaptable to different vehicles, even multi-axle.
The BBW software is compliant to AUTOSAR methodology, and can be interconnected to external software thanks to its open architecture.
The flexible layout of the BBW system, with distributed components, simplifies all industrial assembly, maintenance and end-of-line processes.
Passive safety and space optimization
Thanks to a modular distributed system architecture, the system packaging can be optimized improving the vehicle passive safety design and the space optimization.
Energy consumption optimization
The integration with energy recovery systems enables the optimisation of the recharge of cells in Evs
Suitable for 12/48V electrical systems
The BBW system can be supplied by 12V or 48V electrical systems.
