Vehicle Drive Control Selective Operation After Electrical Leak

The patent segments the drive device into multiple rotating electrical machines (first rotating electrical machine coupled to crankshaft, second rotating electrical machine coupled to wheel). When an anomaly is detected in one machine, the system selectively inhibits only the affected machine while allowing other machines to operate, thereby maintaining partial vehicle functionality and improving user convenience without compromising safety.

The patent applies local quality by differentiating the operational status of each rotating electrical machine based on its specific anomaly status. The control device determines the anomaly location and applies different control strategies to different machines: the machine with anomaly is inhibited, while machines without anomaly continue to operate. This localized approach resolves the contradiction by maintaining safety at the affected location while preserving convenience through continued operation of unaffected components.

The patent divides the drive system into independent controllable units (multiple rotating electrical machines). When an anomaly is detected in one unit, the control device selectively inhibits only that specific unit while allowing other units to continue operation. This segmentation prevents anomaly propagation to the entire system while maintaining partial productivity through continued operation of unaffected machines.

The patent applies partial action by inhibiting only the specific rotating electrical machine with the anomaly rather than completely shutting down the entire vehicle system. This partial inhibition strategy prevents the harmful effects of the anomaly from affecting the whole system while maintaining sufficient vehicle productivity through the operation of remaining healthy machines, thereby resolving the contradiction between safety and productivity.
