Today, new technologies that emphasize safety and comfort are being developed in the automotive sector. The mechanical systems used in automobiles are gradually being replaced by electronic systems. These systems are generally called x-by-wire systems. Brake-by-wire (electronic braking) is one of them. However, since these systems require more electrical power to operate, it is planned to increase the electrical power in the vehicles to 42 Volts. That is, the brake-by-wire system depends on whether the 42 Volt power supply is applicable. In short, the systems with the 12 Volt battery and the 14 Volt alternator, which have been sufficient to date, are no longer sufficient due to new electrical and electronic equipment added to the vehicle. The automotive industry is now looking for a system with an 36 Volt battery and an 42 Volt alternator to meet these demands.

It consists of an electromechanical braking system, sensors placed on the brake pedal, a control unit and electromechanical actuators on the wheels. This system provides high efficiency in braking control. There will be no need for hydraulic oils and mechanical connections found in conventional brake systems.

The biggest benefit of the brake-by-wire system is that it reduces equipment in the vehicle. Systems such as the ABS (automatic braking) system, traction control system and ESP (electronic stabilization program) will be integrated into a single electronic brake system.

In addition to the brake-by-wire system, other x-by-wire systems are being designed. For example, the steer-by-wire system. This system does not have a drive shaft between the steering wheel and the front wheels. The steering angle will be transferred to a system that controls the direction of the front wheels by cables and the system will direct the wheels. This system is a preparation for future driverless vehicles.

As can be seen in these examples, electrical and electronic systems in automobiles are undergoing major development and will need to be tested to see if these systems meet electromagnetic compatibility standards.

At least today, it is important that at least the parking sensors and parking applications, or the cruise system or the ESP electronic compensation program, operate without interfering with other systems. Today, many electromagnetic compatibility (EMC) tests are performed by the accredited test and inspection organizations for the automotive industry in accordance with the relevant regulations and standards issued by domestic and foreign organizations.
