The Device for Measuring Forces in the Toe-In Control System of a Vehicle

The article discusses issues pertaining to the measurement of lateral forces acting on the wheels of a vehicle, which is a prerequisite to enhance the efficiency of the currently used toe-in control systems of a vehicle in motion.  Passive toe-in control systems have been used for a relatively long time. Recent years have seen the appearance of production vehicles equipped with an active toe-in control system. For efficient toe-in control, it is necessary to estimate the lateral forces, which the implemented system design does not provide as it does not involve direct measurement of the lateral forces (they are estimated indirectly). The proposed device eliminates this drawback. The development of control techniques for the systems where this device could be utilized, involves the use of easy to use lateral force sensors. They can be easily installed into wheel assemblies of modern vehicles without compromising their weight characteristics, and having only an insignificant impact on the cost of the construction.
