Abstract
PURPOSE:To permit the slip of a crawler to be detected exactly even on ungrad ed ground by a method in which sensors to detect the acceleration in the back and forth directions of vehicular body and the speed of crawler are set, and an arithmetic circuit is made up to calculate vehicular speed and slip rate of crawler for slip detection. CONSTITUTION:A sensor 2 to detect the acceleration in the back and forth directions of vehicular body is set, and its signal is sent out to an arithmetic circuit 12. A sensor 8 to detect output rotation of torque converter and a sensor 9 to detect change gear steps are set, and on the basis of signal from the sensors, the speed of crawler 7 is calculated in an arithmetic circuit 11. Further more, on the basis of signals from the sensor 2 and the circuit 11, the slip rate of the crawler 7 is calculated in the circuit 12. The slip rate can thus be exactly detected without malfunction even on water surface or ungraded ground.
