Abstract

A control apparatus of a hybrid leaning vehicle includes: a travel mode request section that requests one travel mode selected from a plurality of travel modes including a first travel mode in which an engine is operated with a clutch disengaged and a second travel mode in which the engine is operated with the clutch engaged; and a travel mode setting section. When the travel mode request section requests the second travel mode during travel in the first travel mode, the travel mode setting section, upon determining that a shock accepting condition is satisfied, sets the second travel mode as the travel mode to be executed and, upon determining that the shock accepting condition is not satisfied, prohibits the second travel mode from being set as the travel mode to be executed.

First claim

What is claimed is:

1. A control apparatus of a hybrid leaning vehicle including an engine serving as a drive source for travel of the hybrid leaning vehicle, an electric motor serving as a drive source for travel of the hybrid leaning vehicle, and a clutch provided in a power transmission route between the engine and a drive wheel, the control apparatus comprising:
a travel mode request section that requests one travel mode selected from a plurality of travel modes including a first travel mode in which the engine is operated with the clutch disengaged and a second travel mode in which the engine is operated with the clutch engaged; and
a travel mode setting section that determines whether a predetermined shock accepting condition is satisfied and that, depending on a result of the determination, sets the travel mode requested by the travel mode request section as a travel mode to be executed, wherein
when the travel mode request section requests the second travel mode during travel in the first travel mode, the travel mode setting section, upon determining that the shock accepting condition is satisfied, sets the second travel mode as the travel mode to be executed, and
when the travel mode request section requests the second travel mode during travel in the first travel mode, the travel mode setting section, upon determining that the shock accepting condition is not satisfied, prohibits the second travel mode from being set as the travel mode to be executed.

2. The control apparatus according to claim 1 , wherein the shock accepting condition includes a condition that a rotation angle of a vehicle body of the hybrid leaning vehicle about a front-rear axis of the vehicle body has an absolute value less than a predetermined threshold, the rotation angle being an angle of rotation from an upright position of the vehicle body.

3. The control apparatus according to claim 1 , wherein the shock accepting condition includes a condition that an angular velocity of a vehicle body of the hybrid leaning vehicle about a front-rear axis of the vehicle body has an absolute value less than a predetermined threshold.

4. The control apparatus according to claim 1 , wherein the shock accepting condition includes at least one condition selected from: a condition that a rotation angle of a vehicle body of the hybrid leaning vehicle about a left-right axis of the vehicle body has an absolute value less than a predetermined threshold, the rotation angle being an angle of rotation form an upright position of the vehicle; and a condition that an angular velocity of the vehicle body about the left-right axis has an absolute value less than a predetermined threshold.

5. The control apparatus according to claim 4 , wherein the shock accepting condition includes a condition that the rotation angle about the left-right axis is less than a predetermined threshold in a rearward inclination direction and that a torque transmitted to the drive wheel is a positive value.

6. The control apparatus according to claim 4 , wherein the shock accepting condition includes a condition that the rotation angle about the left-right axis is less than a predetermined threshold in a forward inclination direction and that a torque transmitted to the drive wheel is a negative value.

7. The control apparatus according to claim 1 , wherein the shock accepting condition includes a condition that a vehicle speed of the leaning vehicle is equal to or higher than a predetermined threshold.

8. The control apparatus according to claim 1 , wherein the shock accepting condition includes a condition that a slip ratio of the leaning vehicle is less than a predetermined threshold.

9. The control apparatus according to claim 1 , wherein the shock accepting condition includes a condition that a rotational speed of the engine is equal to or higher than a predetermined threshold.

10. The control apparatus according to claim 1 , wherein the shock accepting condition includes a condition that at least a predetermined time has elapsed from start-up of the engine and a rotational speed of the electric motor is less than a predetermined threshold.

11. The control apparatus according to claim 1 , wherein
the plurality of travel modes further includes a third travel mode in which the engine is stopped and the electric motor is operated,
the travel mode setting section determines whether a steady turning condition is satisfied, the steady turning condition including a first condition that the leaning vehicle is determined to be in a predetermined steady turning state or a second condition that the leaning vehicle is predicted to remain in the steady turning state for at least a predetermined time,
when the travel mode request section requests the first travel mode during travel in the third travel mode, the travel mode setting section, upon determining that the steady turning condition is satisfied, sets the first travel mode as the travel mode to be executed, and
when the travel mode request section requests the first travel mode during travel in the third travel mode, the travel mode setting section, upon determining that the steady turning condition is not satisfied, prohibits the first travel mode from being set as the travel mode to be executed.
