Idle/slide controller for vehicle

Abstract

Abstract PURPOSE:To improve the detecting accuracy of idle and slide of a vehicle by removing and correcting a deviation component of a speed signal proportional to the rotating speed of wheels and producing only the idle or slide component. CONSTITUTION:When driving wheels happen to idle, the induced terminal voltages of main motors connected directly to shafts rise, and a voltage difference E is generated between main motors 2A and 2B. This is detected by a DC voltage detector 4, and input to an arithmetic processor 7. The processor 7 judges whether the differential value of an input signal e1 falls within a set range or not, sets a differentiated value output =0 when it falls within the range, and sets a differential value output when it is out of the range. Then, it judges whether an integration signal obtained by integrating the differential value output falls in a set range near '0' or not, processes to converge the integration signal to '0' when it falls within the range, and slightly increases or decreases the integration signal together with a time or vehicle speed when it is out of the range to obtain a signal e4, and applies it to an idle/slide controller 8.
