Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).
The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...
Gyroscopes measure the angular rate of rotational movement about one or more axes. Gyroscopes can measure complex motion accurately in multiple dimensions, tracking the position and rotation of a moving object unlike accelerometers which can only detect the fact that an object has moved or is moving in a particular direction.
When the body is subjected to external surface forces or contact forces, following Euler's equations of motion, internal contact forces and moments are transmitted from point to point in the body, and from one segment to the other through the dividing surface , due to the mechanical contact of one portion of the continuum onto the other (Figure ...
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
The sensors in an ESC system have to send data at all times in order to detect a loss of traction as soon as possible. They have to be resistant to possible forms of interference, such as precipitation or potholes. The most important sensors are as follows: A steering wheel angle sensor that determines where the driver wants to steer.

There are two types of yaw-rate sensors: piezoelectric and micromechanical. In the piezoelectric type, the sensor is a tuning fork-shaped structure with four piezoelectric elements, two on top and two below. When the slip angle is zero (no slip), the upper elements produce no voltage as no Coriolis force acts on them.
