US 2006/0032689 A1 · Power module driving control apparatus and hybrid vehicle

Abstract

To provide a power module driving control apparatus and a hybrid vehicle capable of obtaining sufficient accelerator response despite adoption of a speed sensing type clutch for connection and disconnection of a power drive between an engine side and a driving wheel side. When a rotational speed on an input side of a centrifugal clutch falls short of a set value, at which the clutch can be connected, and an acceleration request is made by a rider, a control unit controls a motor generator so as to bring the rotational speed on the input side of the clutch near to the set value. When the motor generator is made to function as a motor, rotation on the input side of the clutch is assisted. When the motor generator functions as a generator, an amount of electricity generated is decreased.

Dependent claims

A driving control apparatus for a power module, comprising:

an engine serving as a power drive source;
a motor generator connected to a crankshaft of the engine, for functioning as a motor and a generator;
a speed sensing type clutch, an input side of which is connected to the crankshaft and an output side of which is connected to a driving wheel side, for connecting the input side and the output side when a rotational speed on the input side becomes equal to, or more than, a set value;
and
control means for controlling the motor generator;
wherein when an acceleration request is made under a condition, in which the rotational speed on the input side of the clutch falls short of the set value, the control means controls the motor generator so as to bring the rotational speed on the input side of the clutch near to the set value.

A hybrid vehicle, comprising:

an engine serving as a first power drive source;
a motor generator connected to a crankshaft of the engine, for functioning as a motor and a generator;
a speed sensing type clutch, an input side of which is connected to the crankshaft and an output side of which is connected to a driving wheel side, for connecting the input side and the output side when a rotational speed on the input side becomes equal to, or more than, a set value;
control means for controlling the motor generator;
and
an electric motor disposed between the output side of the clutch and the driving wheel, for functioning as a second power drive source, the clutch being connected when drive by the electric motor is changed to drive by the engine;
wherein, when an acceleration request is made under a condition, in which the rotational speed on the input side of the clutch falls short of the set value, the control means controls the motor generator so as to bring the rotational speed on the input side of the clutch near to the set value.
