AI Technical Summary
Technical Problem
In vehicles equipped with mild hybrid systems, if the motor generator fails during auxiliary battery charging, the battery cannot be recharged, leading to a situation known as 'battery raising' or engesturation.
Method used
A vehicle control device that includes an engine, a motor generator, an auxiliary battery, and a control unit. When the motor generator is inoperable, the control unit restarts if there is no restart history and no failure detection, allowing the motor generator to generate electricity again.
Benefits of technology
Enables early electricity generation from the motor generator when it is inoperable, preventing battery depletion and engesturation in vehicles.

Abstract
To be ready for early generation in a case where a motor-generator being required to generate becomes inoperable.SOLUTION: A control apparatus is for use in a vehicle 1 that includes: an engine 2; a motor-generator 5 for use in starting the engine 2 and assisting power of the engine 2; an auxiliary-machine battery 8 for storing power generated by the motor-generator 5; and a control part for controlling the motor-generator 5. In a case where the motor-generator 5 being required to generate becomes inoperable, the control part is restarted if there is no history of restarting the control part, with no detection of information indicating that the motor-generator 5 is failed.SELECTED DRAWING: Figure 1
