Is the drive by wire throttle an issue?

Maybe they think that the speed of operation of drive by wire throttle is very limited and this is going to result in a doughy, spongy performance. There’s obviously the issues of safety. The response rate is definitely something that we notice as an issue in selected OE factory cars running drive by wire throttle.

What are the advantages of wire throttle control?

One of the biggest advantages is, with complete control over the actual opening of the throttle body at the engine this gives the manufacturers a lot of control over the torque delivery of the engine. So no longer are we running a fixed relationship between the driver’s foot pedal position and the accelerator position at the engine.

How does the throttle work on a car?

Specifically when it comes to the safety element which we’ll be focusing on shortly. So the throttle body is fitted with a DC Servo Motor which physically drives the throttle, opening and closing it, based on whatever the driver’s requesting with the accelerator pedal.

How does the throttle respond to the foot pedal?

We did find there were several models of car where the throttle response, or the speed that the throttle responds to the driver’s foot pedal, tended to be dulled down a little bit and gave a sort of a doughy response to the way the car drove.

What causes a throttle by wire problem in a car?

Most of the faults that occur in TBW systems relate to pedal or throttle position sensors that may wear out, skip or emit erratic signals. Throttle body motor failures and electrical problems, such as loose or corroded, wiring connectors are also common.

Is the gas pedal connected to the throttle?

A mechanically linked throttle has existed since the very first “motor carriages” were built. Whether the gas pedal connected to the engine with a cable or rods, the link between the driver and the command for power were always a physical one. Now, sophisticated electronic control modules, sensors and actuators have replaced almost all.

Is there such a thing as drive by wire?

This system is called Throttle-By-Wire (TBW) or Drive-by-Wire, and it has plenty of advantages, but diagnosing trouble takes a bit more sleuthing than in the old days.

How does an electric throttle actuator control work?

An electric throttle actuator control (TAC) is made of a throttle control motor and two throttle position sensors. When the throttle valve moves, the two throttle position sensors respond with a signal to verify position. These sensors act as potentiometers to convert the throttle valve position into a voltage signal that is sent to the ECM.
