Preventing drive wheel spin in two wheel drive motor vehicle

摘要

The drive wheel spin is determined by comparing the measured mean rotation speed for the driven and non-driven wheels. These mean values are obtained by multiplying the prim. value derived from the actual measured rotation speed, with an specific coefficient pre-determined for each of the wheels, giving the percentage deviation from the mean value for the dynamic rotation circumference for all four wheels. The device for carrying out these measurements and calculations is also claimed.
