Brake-By-Wire, an electromechanical brake technology, will increase vehicle economy, while helping electric cars maintain its competitive edge in automotive design. Lighter weight of vehicle contributes to less energy consumption and minimizes tire wear.
Environmental benefits: eco brake system saves energy and eliminates dust pollution.
Average automotive braking system weight is about 176 lbs / 80 kg (discs, calipers, brake pads, power booster, hydraulic master cylinder, ABS control unit and tubes).
Proposed Brake-By-Wire system total weight is 66 lbs - 30 kg. The 110 lbs - 50 kg less than the average hydraulic brakes system,
reducing an automobile’s weight by 110 lbs - 50 kg increases vehicle economy by up to 3%. Those 3% represents a significant reduction of energy consumption.
The electrorheological fluid brake system has high-speed of response, reducing braking distance that is extremely important in emergency situations.
There are an estimated 260 million registered passenger vehicles in the United States and over 33 million in Canada.
Brake-By-Wire pros and cons, versus hydraulic brakes:
• Compact design
• Better controllability of brake torque
• Light weight
• Less energy usage
• Constant Anti-Skid monitoring
• High-speed of response, reduced braking distance
• Long lifespan, no friction linings and no parts replacement
• Hydraulic system is not required
• Low or no maintenance
• No harmful dust pollution
• Require of an alternating electric current to generate braking torque
• Temperature dependency, when temperature increased viscosity decreased
• Lifespan of electrorheological fluid is unknown
• Current suspension design require modification
