Is it necessary to use turn signals for autonomous lane changes?

[Eleanor]

Autonomous lane changes require the use of turn signals. Introduction: Turn signals are important indicator lights that are activated when a motor vehicle changes direction to alert surrounding vehicles and pedestrians. The turn signal bulbs use xenon tubes, controlled by a microcontroller circuit, which flash alternately left and right without interruption. Turn signals utilize flashers to achieve the blinking effect. They can mainly be categorized into three types: resistance wire type, capacitor type, and electronic type. Structural Principle: The resistance wire type can be further divided into thermal wire type (electrothermal) and wing type (spring-loaded), while the electronic type can be subdivided into hybrid type (relay with contacts and electronic components) and fully electronic type (no relay). For example, the spring-loaded flasher operates on the principle of thermal expansion and contraction, using the heat generated by electric current to cause sudden movements in the spring strip, thereby connecting and disconnecting the contacts to achieve the blinking effect.
