Control apparatus

1. A saddle-ride type vehicle control apparatus comprising:

an acquiring unit that acquires information indicating a posture of an occupant of a saddle-ride type vehicle;

a determining unit that determines a level of intervention in driving of the saddle-ride type vehicle based on the posture of the occupant indicated by the information acquired by the acquiring unit; and

an intervening unit that intervenes in the driving of the saddle-ride type vehicle based on a condition of the saddle-ride type vehicle and the level of intervention determined by the determining unit, wherein

the determining unit compares postures of the occupant before and after the intervening unit operates a braking device of the saddle-ride type vehicle, and

as a postural change of the occupant indicated by a result of the comparison increases, the level of intervention in the driving of the saddle-ride type vehicle determined by the determining unit lowers.

2. The control apparatus according to claim 1 , wherein the intervention includes main intervention, and preliminary intervention which is executed in advance prior to the main intervention at a lower level of intervention than the main intervention.

3. The control apparatus according to claim 1 , wherein the posture of the occupant is judged based on force applied to a seat on which the occupant is seated, or force applied to a step on which the occupant places a foot.

4. The control apparatus according to claim 3 , wherein as a difference in applied force between left and right steps increases, or a degree of non-uniformity within the seat surface of the seat of force applied to the seat surface increases, the level of intervention in the driving of the saddle-ride type vehicle determined by the determining unit lowers.

5. The control apparatus according to claim 1 , wherein

the acquiring unit further acquires information indicating a line of sight of the occupant, and

the determining unit changes the level of intervention based on the line of sight of the occupant indicated by the information acquired by the acquiring unit.

6. The control apparatus according to claim 1 , wherein

the acquiring unit further acquires information indicating a direction of a head portion of the occupant, and

the determining unit changes the level of intervention based on the direction of the head portion of the occupant indicated by the information acquired by the acquiring unit.

7. The control apparatus according to claim 1 , wherein as a permissible intervention amount for the occupant set based on the posture of the occupant decreases, the level of intervention in the driving of the saddle-ride type vehicle determined by the determining unit lowers.

8. The control apparatus according to claim 5 , wherein as a permissible intervention amount for the occupant set based on the line of sight of the occupant decreases, the level of intervention in the driving of the saddle-ride type vehicle determined by the determining unit lowers.

9. The control apparatus according to claim 6 , wherein as a permissible intervention amount for the occupant set based on the direction of the head portion of the occupant decreases, the level of intervention in the driving of the saddle-ride type vehicle determined by the determining unit lowers.

10. The control apparatus according to claim 1 , wherein the intervening unit performs emergency braking control, and operates a braking device of the saddle-ride type vehicle based on braking force set based on: a positional relationship between an object around the saddle-ride type vehicle and the saddle-ride type vehicle; and the level of intervention determined by the determining unit.

11. The control apparatus according to claim 1 , wherein the information indicating the posture of the occupant includes information indicating at least one of: knee grip force of the occupant, force applied to a grip portion of a steering handle gripped by the occupant; a lean angle of the saddle-ride type vehicle; and force applied to a front wheel and a rear wheel of the saddle-ride type vehicle.

12. The control apparatus according to claim 11 , wherein the determining unit determines the level of intervention in the driving of the saddle-ride type vehicle based on a balance of applied force between the front wheel and the rear wheel of the saddle-ride type vehicle.

13. The control apparatus according to claim 1 , wherein

the acquiring unit further acquires information indicating whether or not a passenger is present, and

the level of intervention in the driving of the saddle-ride type vehicle determined by the determining unit lowers if the information acquired by the acquiring unit indicates that a passenger is present.

14. A saddle-ride type vehicle control apparatus comprising:

an acquiring unit that acquires information indicating a posture of an occupant of a saddle-ride type vehicle;

a determining unit that determines a level of intervention in driving of the saddle-ride type vehicle based on the posture of the occupant indicated by the information acquired by the acquiring unit; and

an intervening unit that intervenes in the driving of the saddle-ride type vehicle based on a condition of the saddle-ride type vehicle and the level of intervention determined by the determining unit, wherein

the determining unit compares postures of the occupant before and after the intervening unit operates a braking device of the saddle-ride type vehicle, and

as a postural change of the occupant indicated by a result of the comparison decreases, the level of intervention in the driving of the saddle-ride type vehicle determined by the determining unit rises.
