摘要： The present teaching aims to enable a vehicle including a magnet type motor to move forward with an increased responsiveness to an operation on an accelerator operator, and especially with an increased responsiveness at a time when the vehicle once decelerating switches to accelerating.
The present teaching provides a vehicle including: an engine; a magnet type motor; an electricity storage device; a driven member; an accelerator operator; and a control section that controls the magnet type motor and the engine such that, when no torque request is received while the vehicle is decelerating, the control section stops a combustion action of the engine and performs deceleration-time motoring whereby the magnet type motor causes a crankshaft to rotate with electricity in the electricity storage device in order that rotation of the crankshaft continues with deceleration, the deceleration-time motoring being performed in at least part of a period for which the vehicle is decelerating.

摘要： [PROBLEM]
To provide a straddled vehicle that is able to shorten a time period until completion of engine start after an engine start instruction.
[SOLUTION]
An engine unit includes a single-cylinder engine, a compression release mechanism, a drive wheel, a permanent magnet type motor, a battery, an inverter including a plurality of switching parts, and a control device. The control device controls the switching parts in such a manner that, upon reception of a start instruction for starting the single-cylinder engine, the permanent magnet type motor moves a piston so as to operate the compression release mechanism in a compression stroke of a first combustion cycle, and then the permanent magnet type motor applies a force to the piston via a crankshaft such that the rotation speed of the crankshaft in a second combustion cycle exceeds the pressure-reduction upper limit speed for the compression release mechanism, so that the piston is moved without operating the compression release mechanism in a compression stroke of the second combustion cycle, thus assisting compression of the mixed gas.

摘要： The present teaching aims to provide a straddled vehicle equipped with an independent throttle engine capable of achieving both a degree of design freedom for catalyst layout and an early activation of a catalyst.
The present teaching provides a straddled vehicle equipped with an independent throttle engine, the vehicle including an independent throttle engine, an exhaust passage, a silencer, a catalyst, a magnet type motor, an electricity storage device, a driven member, and a control section. The control section operates the magnet type motor and the independent throttle engine such that, at a time of a cold start, firstly, the magnet type motor uses electricity in the electricity storage device to cause forward rotation of the crankshaft with a combustion action of the independent throttle engine stopped, until a rotation speed of the crankshaft exceeds an idling rotation speed of the independent throttle engine, and then in a state where the rotation speed of the crankshaft exceeds the idling rotation speed of the independent throttle engine, the independent throttle engine supplies air through each throttle valve as well as a fuel to each cylinder and starts the combustion action.

The amount of power generated by the permanent magnet type rotary electric machine in a time period during which a highest power generation efficiency load control is applied is greater than power consumed by the power consuming apparatus. The amount of power generated by the permanent magnet type rotary electric machine in a time period during which a lowest power generation efficiency load control is applied is equal to or less than power consumed by the power consuming apparatus.

摘要： The present teaching aims to enable a vehicle including a motor generator to move forward with an increased responsiveness to a departure operation.
The present teaching provides a vehicle including: an engine; a magnet type motor generator including a rotor and a stator, the rotor including a permanent magnet and being connected to a crankshaft such that power transmission between the rotor and the crankshaft is allowed without interposition of a clutch and such that the rotor rotates with a fixed speed ratio relative to the crankshaft, the stator being arranged opposed to the rotor, the magnet type motor generator being configured to rotate the crankshaft at least when starting a combustion action of the engine and to generate electricity when being driven by the engine; an electricity storage device; an accelerator operator; a driven member configured to be driven by power outputted from the engine, to make the vehicle move forward; a power transmission device; and a control section. The power transmission device is configured to allow power transmission between the crankshaft and the driven member before a rotation speed of the crankshaft reaches 2000 rpm during an increase in the rotation speed of the crankshaft. In response to the accelerator operator being operated so as to instruct the engine to make an output in a state where the combustion action of the engine is stopped, the control section controls the magnet type motor generator such that the magnet type motor generator causes the crankshaft to rotate using electricity in the electricity storage device with the combustion action of the engine stopped, and before the rotation speed of the crankshaft reaches 2000 rpm, the control section supplies a fuel to the engine and starts the combustion action of the engine. The driven member is configured to be driven by power of the crankshaft caused by combustion of the engine before the rotation speed of the crankshaft reaches 2000 rpm during an increase in the rotation speed of the crankshaft.
