HOW BRAKE-BY-WIRE WORKS
When the driver steps on the brake pedal, he is sending an electronic message to the brakes electronic module, the electronic module reads the information and responds by applying electric field on the electrorheological fluid brake units connected to the wheels.When an electric field is applied across the electrorheological fluid, the fluid viscosity changes and braking torque is generated, forcing the vehicle to slow down or stop.
New Brake-By-Wire system consists of a rotating grooved disk immersed in an electrorheological fluid.
In principle, the brake torque can be controlled by changing the electric current applied on the electrorheological fluid, a compound containing fine particles in suspension stiffens in the presence of an electrical current. When an electric field is applied across the gap between the disk and the housing filled with an electrorheological fluid, the fluid viscosity change and braking torque is generated, forcing the vehicle to slow down or stop.The resistance to the motion of an Electrorheological fluid is controlled by adjusting the applied electric field.
Electrorheological a smart fluid is a fluid whose properties "viscosity" can be changed by applying an electric field.
Summary
New Brake-By-Wire smart fluid brake system can control considerably more mechanical power than the electrical power used to control the effect, it acts as a power amplifier. The electrorheological fluid which can be transformed from the fluid state into the solid state in milliseconds, by applying an electric field to generate braking torque causing the vehicle to slow down or stop.
