Future of Brake-by-Wire in Autonomous Vehicles

The future of automotive braking includes Brake by Wire, transitioning to pure electrical lines for cost-saving and advancing technology.

### The Future of Automotive Brakes: Brake-by-Wire Systems
Brake-by-wire is a new technology that uses an electric signal to apply the brakes, removing the mechanical connection. This system is set to be used in autonomous vehicles and differs from traditional braking systems used in most cars. Audi and other German and European car manufacturers have also started to adopt the brake-by-wire system, similar to the one mentioned for Tesla and autonomous cars.

### The Function of Brake-By-Wire Systems in Cars
Brake-by-wire systems are now included in American, Japanese, and Hyundai cars, allowing the driver to generate pressure, while a simulator creates the sensation of a connection and provides push feedback. The system uses a pedal simulator to measure the pressure and movement of the brake, sending this information to the computer brake control unit for regenerative braking, which is essential for autonomous driving and is relevant to Tesla's technology.

### The Ultimate Brake-by-Wire System and Its Additional Hydraulic Component
Audi introduced the brake-by-wire system, now also adopted by Hyundai, Mercedes-Benz, and BMW, using motors for regenerative braking and a separate pump for hydraulic pressure. The system aims to provide additional gripping force when regenerative braking is not sufficient, but the need for the hydraulic component raises questions about its effectiveness and cost efficiency. The inclusion of the hydraulic pump has been criticized as unnecessary and wasteful, sparking debate in the car industry.

### Transitioning to Brake by Wire: The Cost-Saving and Safety Benefits
The transition to brake by wire eliminates the need for engine and brake oil, reducing maintenance costs. This shift aims to save money, advance technology, and improve safety through the use of simulators for a more natural pedal feel and to ensure the car can still stop in various scenarios. The ultimate goal is cost reduction, despite initial concerns about increased expenses.

### The Transition from Gasoline to Electric Cars: Understanding the Complex Brake System
The transition from traditional gasoline cars to electric cars involves a complex hybrid system, including Ionic brakes, which can lead to potential errors and malfunctions. Despite the disadvantages, the system has the advantage of creating a direct circuit for emergency braking, providing a route to stop the car. The future plan is to eliminate the mechanical backup, but the current hybrid system still allows for stopping the vehicle, despite its complexity.

### The Reality of Brake-By-Wire Systems in Vehicles
Brake-by-wire systems, claimed by some companies, are not actually in use yet, including in the Audi Tron. The operation of airplane brakes is primarily hydraulic, despite some electrical signals, and they have ABS brakes to manage wheel friction. The current difference between future brake systems and the existing brake-by-wire technology needs further examination for a clear understanding.
