Abstract
A hand-propelled machine includes a frame, a traveling assembly, an operating assembly, and a controller. The controller is configured to control the rotational speed of a first electric motor and the rotational speed of a second electric motor based on the state of a first operating member and the state of a second operating member. The controller is further configured to, when the first operating member is operated to a preset position and the second operating member is not operated, control the first electric motor to reverse at a preset rotational speed.
Claims20
A hand-propelled machine, comprising:
- a frame;
- a traveling assembly connected to the frame and used for supporting the hand-propelled machine to move on the ground, wherein the traveling assembly comprises a first traveling wheel, a first electric motor for driving the first traveling wheel, a second traveling wheel, and a second electric motor for driving the second traveling wheel;
- an operating assembly comprising a first operating member and a second operating member for an operator to operate, wherein the first operating member is used for adjusting a rotational speed of the first electric motor, and the second operating member is used for adjusting a rotational speed of the second electric motor;
- and
- a controller configured to control the rotational speed of the first electric motor and the rotational speed of the second electric motor based on a state of the first operating member and a state of the second operating member;
- wherein the controller is further configured to, when the first operating member is operated to a preset position and the second operating member is not operated, control the first electric motor to reverse at a preset rotational speed.
A control method for a hand-propelled machine comprised of a frame, an operating assembly comprising a first operating member and a second operating member for an operator to operate, and a traveling assembly, connected to the frame, comprising a first traveling wheel, a first electric motor for driving the first traveling wheel, a second traveling wheel, and a second electric motor for driving the second traveling wheel where the first operating member is used for adjusting a rotational speed of the first electric motor and the second operating member is used for adjusting a rotational speed of the second electric motor, the control method comprising:
- when the hand-propelled machine moves and when it is detected that the first operating member is operated, detecting a position to which the first operating member is operated in real time, and
- when it is detected that the position to which the first operating member is operated reaches the preset position, controlling the first electric motor to decelerate to zero and then reversely accelerate to the preset rotational speed.
A hand-propelled machine, comprising:
- a frame;
- a traveling assembly connected to the frame and used for supporting the hand-propelled machine to move on the ground, wherein the traveling assembly comprises a first traveling wheel, a first electric motor for driving the first traveling wheel, a second traveling wheel, and a second electric motor for driving the second traveling wheel;
- an operating assembly mounted on the frame and operated by an operator, wherein the operating assembly comprises a first operating member for adjusting a rotational speed of the first electric motor and a second operating member for adjusting a rotational speed of the second electric motor;
- and
- a controller configured to control the rotational speed of the first electric motor and the rotational speed of the second electric motor based on a state of the first operating member and a state of the second operating member;
- wherein the controller is further configured to, when both the first operating member and the second operating member are operated, control both the first electric motor and the second electric motor to decelerate, wherein a respective one of the first electric motor and the second electric motor corresponding to one of the first operating member and the second operating member that has a larger operating amplitude decelerates more.
