What is a Throttle-By-Wire System?
Before delving into the market developments, it’s important to understand what a Throttle-By-Wire (TBW) system is and how it functions. Traditionally, a vehicle’s throttle was controlled by a mechanical cable that connected the accelerator pedal to the engine’s throttle valve. The system used physical linkages to regulate engine speed and power output based on the driver’s pedal input.
However, with Throttle-By-Wire, the physical cable is eliminated, and instead, an electronic sensor detects the driver’s pedal input and sends that data to the vehicle’s engine control unit (ECU). The ECU then processes this input and electronically adjusts the throttle valve to regulate engine speed. This system offers several advantages, including greater precision, faster response times, and the ability to integrate with other electronic systems in the vehicle, such as cruise control and electronic stability programs.
