摘要:
A torque sensor (26) for a human-powered object includes a spindle (50) connecting crank arms (16) of the object. In one embodiment, the object can be a bicycle. The torque sensor (26) further includes at least one strain gauge (52, 54) mounted to the spindle (50) in a shear patterns to measure strain perpendicular to a radius of the spindle (50) and electrically connected in a Wheatstone Bridge arrangement to measure shear strain from torsional forces whilst negating shear strain from bending forces.

An electric self-balancing vehicle (100) including a top cover (1), a bottom cover (3), an inner cover (2), a rotating mechanism (60), two wheels (50), two hub motors (4), a plurality of sensors (80), a power supply (81), and a controller (82) is described herein. The top cover (1) includes a first top cover (11) and a second top cover (12) disposed symmetrically and rotatable relative to each other. The bottom cover (3) is fixed to the top cover (1) and includes a first bottom cover (31) and a second bottom cover (32) disposed symmetrically and rotatable relative to each other. The inner cover is (2) fixed between the top cover (1) and the bottom cover (3) and includes a first inner cover (21) and a second inner cover (22) disposed symmetrically and rotatable relative to each other. The rotating mechanism (60) is fixed between the first inner cover (21) and the second inner cover (22). The two wheels (50) are rotatably fixed at two sides of the inner cover (2), respectively. The two hub motors (4) are fixed in the two wheels (50), respectively. The plurality of sensors (80) is disposed between the bottom cover (3) and the inner cover (2), respectively. The power supply (81) is fixed between the first bottom cover (31) and the first inner cover (21). The controller (82) is fixed between the second bottom cover (32) and the second inner cover (22), the controller (82) is electrically connected with the plurality of sensors (80), the power supply (81), and the hub motors (4), and the controller (82) controls the hub motors (4) to drive the corresponding wheels (50) to rotate according to sensing signals transmitted by the sensors (80).

An angle sensor (14) includes an operating body (14c) and a sensor main body (14d). The operating body (14c) includes integrally a circular disc portion (14e), a rotational center shaft (14f) which is inserted rotationally into a hollow portion of a pivot (12), a connecting arm (14a) which is locked on a connecting arm mounting portion (5e), and a rotational shaft (14b) which is inserted into the sensor main body (14d). The sensor main body (14d) includes a housing and a rotation detection device (14i).
摘要:
Object To suppress an unintended disturbance of the attitude of a driver at a time of automatic brake control in an automatic brake device for a saddle riding type vehicle. Solving Means A brake modulator 10 that controls actuation of front and rear brakes 2 and 3 includes a collision possibility determining unit 19, an automatic brake control unit 21, and a brake operation determining unit 20. When the collision possibility determining unit 19 determines that there is a possibility of collision, and the brake operation determining unit 20 determines that brake operation by a driver is absent, the automatic brake control unit 21 first actuates only the rear brake 3 to generate a rear wheel braking force, and then also actuates the front brake 2 to generate a front wheel braking force.
