Abstract
Official abstract text for this publication.
In a hybrid vehicle including an engine, a motor, a generator, and a battery that is electrically connected to the motor and the generator, an ECU performs “battery-less travel control” enabling the vehicle to travel when a fault occurs in the battery by disconnecting the battery from an electrical system including the motor and the generator and driving the motor using power that is generated by the generator using the power of the engine. When the battery-less travel control is underway and a vehicle speed V exceeds a vehicle speed limit Vsh, the ECU implements a vehicle speed limitation. As a result, a control mode of the motor is less likely to shift to a rectangular control mode during the battery-less travel control.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle that is caused to travel by rotating an output shaft coupled to a drive wheel using drive power generated by at least one of an engine and a motor, comprising: a generator that generates electric power using the power of the engine; a battery configured to be connectable to the motor and the generator; and a control apparatus programmed to: control the motor and the generator, determine if a vehicle speed is lower than a threshold, i…
