In Normal case , ABS only controls the wheel which is in Unstable state (Locking State). The control of ABS is by giving brake pressure increase and decrease depending on the Stability condition of the wheel. So, This will make the wheel velocity from dropping immediately and reducing the slip...

Thanks for answering Orodruin. I totally agree with you and i am in same impression about this. I asked this question to find if there is any specific reason other than this.

Hi all, I would like to know why the Transfre function of the system is represented in S Domain instead of doing all the math in time domain itself. I studied a course on control systems and i wonder why s- domain is taken instead of other domains like Z- domain and others. Please refer belwo...

Thanks for the reply, I would like to know in the case where vehicle is already in slip. I read some where that the friction between the tire and road vary with the variation in slip. So, I am trying to calculate the variation of Mue(Braking force coefficient) with respect to slip. Please refer...

Hi all, I need to calculate the friction coefficient between road and the tyre of the car. I came across few answers like which solves as from the following torque equation. Engine torque = braking torque + acceleration troque + Inertial torque + drag torque + rolling resistance. For...

Hi all, I want to know the why the Braking force coefficient is increasing first and then decreasing with respect to wheel slip. I attached the graph for your reference

Is it based on Flemings Left hand rule ?

The Solenoids which are used for pneumatic controller uses the solenoid as a switch to control the value opening and closing. This is done by passing current to through the coil which produces the magnetic field . But i would like to know how the generated magnetic field will move the solenoid rod?

Thanks...Your answer really convincing and clarified my doubt. :-)

Thanks for your replies. I would like to know the explanation in terms of the phases that it undergoes for 1. Increase 2. Max torque and 3. Decrease. May be the image that i attached you might have misguided you. Please explain the characterstics taking anyone curve i.e., inverted 'U' shape.

Hi all, I want to know reason behind the variation of torque with respect to the rpm of the engine. I understood that the torque would decrease as the engine rpm increases.But, When i look into the characterstics graph of speed vs torque of the crank shaft engine(Graph is attached),It...
