Claims

[Scope of utility model registration request]

In a vehicle equipped with a continuously variable transmission mechanism in the power transmission system from the engine to the wheels, there is a rotating field pole fixed to the engine output shaft, a field coil for exciting this rotating field pole, and the above in the non-energized state. A power generation/electricity means having a stator coil that generates an induced electromotive force by rotating field poles and drives the rotating field poles when energized;
A vehicle control device comprising: engine brake request detection means for detecting a request for engine brake operation; and control means for controlling the power generation/electricity means to perform a power generation operation when the detection means detects an engine brake request. .
