MOWER
Document Type and Number:
WIPO Patent Application WO/2022/102615
Kind Code:
A1
Abstract:
Provided is a mower in which the battery consumption speed, the remaining amount change, the workable time from the full battery state, and the battery replacement time can be predicted. A mower 10 equipped with a mowing motor 70 and traveling drive motors 20A, 20B receives the set input of a target rotation speed and power consumption of the mowing motor 70, obtains an actual power consumption value that varies depending on the load fluctuation of the mowing motor 70 due to an increase or decrease in the amount of grass, by using the battery current measured by the current sensor 132, while maintaining the set target rotation speed of the mowing motor 70, and obtains a new target rotation speed of the traveling drive motors 20A, 20B from the difference between the obtained actual power consumption value and the power consumption set value to control the traveling speed such that the actual power consumption value is within the range of the power consumption set value.
