Abstract

A straddle type vehicle including a vehicle control apparatus capable of controlling a brake by a brake-by-wire method, includes: a control unit configured to control the brake of the straddle type vehicle based on a signal from a brake operation unit; and a signal processing unit configured to supply power of a battery power supply of the straddle type vehicle to the control unit by a predetermined input operation in a handle locking state of the straddle type vehicle.

First claim

What is claimed is:

1. A straddle type vehicle including a vehicle control apparatus capable of controlling a brake by a brake-by-wire method, comprising:
a control unit configured to control the brake of the straddle type vehicle based on a signal from a brake operation unit; and
a signal processing unit configured to supply power of a battery power supply of the straddle type vehicle to the control unit by a predetermined input operation in a handle locking state of the straddle type vehicle.

2. The vehicle according to claim 1 , wherein the input operation includes an operation to an operation unit configured to release the handle locking state.

3. The vehicle according to claim 2 , wherein
the handle locking state is electronically controlled by the brake-by-wire method, and
based on a signal input from the operation unit by the operation,
the signal processing unit supplies the power of the battery power supply to the control unit, and the control unit activated based on the battery power supply controls the brake before release of the handle locking state.

4. The vehicle according to claim 1 , wherein
the input operation includes an operation to the brake operation unit, and
based on a signal input from the brake operation unit by the operation, the signal processing unit supplies the power of the battery power supply to the control unit, and the control unit activated based on the battery power supply controls the brake before release of the handle locking state.

5. The vehicle according to claim 1 , further comprising a detection unit configured to detect a tilt angle of the straddle type vehicle in a pitching direction,
wherein if the tilt angle is not less than a threshold based on comparison between the tilt angle and the threshold, the control unit determines that the straddle type vehicle is in a tilt state and controls the brake.

6. The vehicle according to claim 5 , wherein if the tilt angle is less than the threshold, the control unit determines that the straddle type vehicle is not in the tilt state and controls the brake at a first timing, and
if the control unit determines that the vehicle is in the tilt state, the control unit controls the brake at a second timing earlier than the first timing.

7. The vehicle according to claim 6 , wherein the control unit controls the brake at a timing earlier than the first timing as a degree of the tilt state is higher.

8. The vehicle according to claim 1 , wherein the signal processing unit supplies the power of the battery power supply to the control unit based on a signal input at the time of an operation of the brake operation unit.

9. The vehicle according to claim 1 , wherein a pressure sensitive unit configured to detect an applied pressure and outputting a signal corresponding to the detected pressure to the signal processing unit is arranged as the brake operation unit on a grip of a handle of the straddle type vehicle, and
the signal processing unit supplies the power of the battery power supply to the control unit based on the signal output from the pressure sensitive unit.

10. The vehicle according to claim 9 , wherein the pressure sensitive unit is arranged in an inner circumferential direction of the grip, and a detection range of the pressure sensitive unit is formed in a half region of a region of the grip in the inner circumferential direction on a front side of the straddle type vehicle.

11. The vehicle according to claim 10 , wherein
a convex portion is formed in part of a surface of the grip of the handle, and
the convex portion is formed within the detection range of the pressure sensitive unit.

12. The vehicle according to claim 9 , wherein
the signal processing unit comprises a coefficient setting unit configured to set a coefficient for amplifying an electrical signal output from the pressure sensitive unit,
the signal processing unit inputs, to the control unit, a signal multiplied by the coefficient set by the coefficient setting unit, and
the control unit controls the brake so that a braking force based on the signal is generated.

13. A vehicle control apparatus capable of controlling a brake of a vehicle by a brake-by-wire method, comprising:
a control unit configured to control the brake of the vehicle based on a signal from a brake operation unit; and
a signal processing unit configured to supply power of a battery power supply of the vehicle to the control unit by a predetermined input operation in a handle locking state of the vehicle.

14. A vehicle control method in a vehicle control apparatus including a control unit configured to control a brake of a vehicle based on a signal from a brake operation unit, the vehicle control apparatus being capable of controlling the brake of the vehicle by a brake-by-wire method, comprising
supplying power of a battery power supply of the vehicle to the control unit by a predetermined input operation in a handle locking state of the vehicle.

15. A non-transitory computer-readable storage medium storing a program for causing a computer to execute a vehicle control method in a vehicle control apparatus including a control unit configured to control a brake of a vehicle based on a signal from a brake operation unit, the vehicle control apparatus being capable of controlling the brake of the vehicle by a brake-by-wire method, the vehicle control method comprising
supplying power of a battery power supply of the vehicle to the control unit by a predetermined input operation in a handle locking state of the vehicle.
