Abstract
An electric power equipment includes a drive source, a clutch provided in a power transmission path between the drive source and the travel unit and a controller for controlling an operation of the drive source. Wherein the controller is configured that in a process of increasing a speed in accordance with a rotational speed command value, when a rotational speed of the drive source reaches the clutch connection rotational speed, the increasing of the speed in accordance with the rotational speed command value is interrupted, and when the rotational speed of the drive source reaches a predetermined rotational speed, the increasing of the speed in accordance with the rotational speed command value is performed.
Claims5
An electric power equipment, comprising:
- a work unit for performing a prescribed work;
- a travel unit for enabling the electric power equipment to travel on a ground surface;
- a drive source for driving the travel unit;
- a clutch provided in a power transmission path between the drive source and the travel unit for switching between a transmission and a discontinuation of a power transmission from the drive source to the travel unit, wherein the clutch is configured that the clutch is turned on when a rotational speed of the power transmission path between the drive source and the travel unit reaches a clutch connection rotational speed of the clutch;
- and
- a controller for controlling an operation of the drive source;
- wherein the controller is configured such that in a process of increasing a speed in accordance with a rotational speed command value,
- when a rotational speed of the drive source reaches the clutch connection rotational speed, the increasing of the speed in accordance with the rotational speed command value is interrupted, wherein the rotational speed command value is held substantially constant, and
- when the rotational speed of the drive source reaches a predetermined rotational speed, the increasing of the speed in accordance with the rotational speed command value is performed,
- wherein the controller is configured such that in the process of increasing the speed in accordance with the rotational speed command value, the predetermined rotational speed is an arbitrary minimum rotational speed equal to or less than the clutch connection rotational speed, and
- when the rotational speed of the drive source reaches the arbitrary minimum rotational speed, the speed in accordance with the rotational speed command value is increased from the arbitrary minimum rotational speed according to a predetermined acceleration curve.
An electric power equipment, comprising:
- a work unit for performing a prescribed work;
- a travel unit for enabling the electric power equipment to travel on a ground surface;
- a drive source for driving the travel unit;
- a clutch provided in a power transmission path between the drive source and the travel unit for switching between a transmission and a discontinuation of a power transmission from the drive source to the travel unit, wherein the clutch is configured such that the clutch is turned on when a rotational speed of the power transmission path between the drive source and the travel unit reaches a clutch connection rotational speed of the clutch;
- and
- a controller for controlling an operation of the drive source;
- wherein the controller is configured such that in a process of increasing a speed in accordance with a rotational speed command value,
- when a rotational speed of the drive source reaches the clutch connection rotational speed, the increasing of the speed in accordance with the rotational speed command value is interrupted, wherein the rotational speed command value is held substantially constant, and
- when the rotational speed of the drive source reaches a predetermined rotational speed, the increasing of the speed in accordance with the rotational speed command value is performed,
- wherein the electric power equipment further comprises:
- a load detector for detecting a load of the drive source, wherein the controller is configured such that after the increasing of the speed in accordance with the rotational speed command value is interrupted and when the load is equal to or larger than a predetermined load value, the speed in accordance with the rotational speed command value is increased.
