WIPO Patent Application WO/2016/117433
Kind Code:
A1
Abstract:
In an automobile provided with motors for individually driving left and right driving wheels, in cases when a malfunction occurs in one motor or one inverter device, travel for withdrawing or moving to a repair point can be carried out safely, while swiftly stabilizing vehicle behaviour as much as possible. The present invention is applicable to an electric automobile provided with: motors (5) for individually driving left and right driving wheels (2); left and right inverter devices (12) provided with control units (14a) for individually controlling the respective motors (5); and an ECU (11). An inter-inverter communication means (19) for performing communication between the left and right inverter devices (12) is provided. Mutual control units (14b) are provided which, when a malfunction occurs in any one of the motors (5) for individually driving the left and right driving wheels (2), or in any one of the inverter devices (12) therefor, use the inter-inverter communication means (19) to restrict the output of the other inverter device (12) without involving the ECU (11).
