摘要： A leaning vehicle including an electric-motor-driven automatic-controlled transmission, which has improved followability of the driving force in response to an operation of the accelerator by the rider while the leaning vehicle decelerates or accelerates, is provided.
In a leaning vehicle (1), an upstream rotating electric machine (90) is provided upstream of an electric-motor-driven automatic-controlled transmission (50) on a power transmission path from a crankshaft (21) to a driving wheel (3). While the leaning vehicle (1) accelerates or decelerates, a controller (105) is able to perform both transmission control of changing a transmission ratio by controlling an electric motor (71) of the electric-motor-driven automatic-controlled transmission (50) and rotating electric machine control of changing a torque applied to the upstream of the electric-motor-driven automatic-controlled transmission (50) on the power transmission path by controlling the upstream rotating electric machine (90). In the rotating electric machine control while the leaning vehicle (1) accelerates, the torque in the positive rotational direction of the crankshaft (21) imparted to the upstream of the electric-motor-driven automatic-controlled transmission (50) on the power transmission path is changed by controlling the upstream rotating electric machine (90). In the rotating electric machine control when the leaning vehicle (1) decelerates, the torque in the reverse rotational direction of the crankshaft (21) imparted to the upstream of the electric-motor-driven automatic-controlled transmission (50) on the power transmission path is changed by controlling the upstream rotating electric machine (90).

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.

摘要： In a leaning vehicle 1 on which a rubber-belt-type continuously variable transmission device 30 is mounted, the degree of freedom in controlling braking force applied to a rear wheel 3 by engine braking is further improved.
The leaning vehicle 1 includes a vehicle body frame 7 leaning in the left-right direction of the vehicle, an engine 20 including a crankshaft 21, a front wheel 2, a rear wheel 3, a rubber-belt-type continuously variable transmission device 30 which transmits power from the crankshaft 21 to the rear wheel 3, and a rear wheel braking force controller 120. The rear wheel braking force controller 120 includes at least one of an electric actuator 70 which changes the winding diameter of a rubber belt 32 of the rubber-belt-type continuously variable transmission device 30, a crankshaft motor generator 90 which applies torque to the crankshaft 21, or a rear wheel motor generator 80 which applies torque to the rear wheel 3. The rubber-belt-type continuously variable transmission device 30 is arranged so that a difference between the maximum speed transmission ratio and the minimum transmission ratio is larger than a rubber belt change amount. At least after the leaning vehicle 1 reaches the maximum speed and then shifts to a deceleration state, the rear wheel braking force controller 120 controls the braking force applied to the rear wheel 3.
