A car equipped with brake by wire technology has a small electric motor near the wheels that generate the braking pressure. They are governed by electronic control units connected to the brake pedal that receive input from the driverís actions and interpret that information into a series of electronic instructions. These instructions are then communicated through a miniature, real time network connecting the entire braking system.
The system also has a series of sensors that monitor both the vehicleís operations and the driverís actions and automatically adapt the braking performance to maintain safety. When the driver applies pressure to the brake pedal, information is electronically passed through the system, the external situation is evaluated, and the brake motors apply the correct amount of pressure to the wheels. All of this happens in a split second and without requiring action from any mechanical parts.
