Drive by Wire: The Coming Rise of Vehicle Control Systems
The modern automobile has come a long way from the early 1900s. Advancements in technology have vastly improved vehicle performance, safety, and driving experience. One emerging technology that is revolutionizing vehicular control systems is Drive by Wire.
What is Drive by Wire?
A Drive by Wire system replaces the traditional mechanical control linkages between the driver and vehicle components with electronic signals. In a traditional vehicle, the steering wheel, brake, and accelerator pedals are directly connected via cables or rods to mechanical systems that control vehicle motion. With Drive by Wire, these physical linkages are removed and an electronic interface controls the vehicle subsystems based on driver inputs.
The core components of a Drive by Wire system are sensors on the steering wheel, brake, and accelerator pedals that detect driver commands. These sensor signals are then transmitted electronically to computers controlling the steering, braking, and throttle. Actuators powered by electronic signals move vehicle components like steering racks, brake calipers, and throttle bodies to execute driver inputs.
