Abstract
A work machine system includes: a machine main body to which a work implement is attached; a travel unit that causes the machine main body to travel; an inclination sensor that senses a degree of inclination of the machine main body; an operator presence sensor that senses presence of an operator; a parking brake that brakes the travel unit; an operation device that receives an operation of activating the parking brake; and a controller that performs, when the operation device does not receive the operation, control to prevent the parking brake from being forgotten to be applied, on conditions that the presence of the operator is not sensed and the machine main body is inclined.

A work machine system comprising:
- a machine main body to which a work implement is attached;
- a travel unit that causes the machine main body to travel;
- an inclination sensor that senses a degree of inclination of the machine main body;
- an operator presence sensor that senses presence of an operator;
- a parking brake that brakes the travel unit;
- an operation device that receives a first operation of activating the parking brake;
- and
- a controller that performs, when the operation device does not receive the first operation, control to prevent the parking brake from being forgotten to be applied, on conditions that the presence of the operator is not sensed and the machine main body is inclined.
A method for controlling a work machine, the method comprising:
- sensing, by a first sensor, whether or not an operator of a work machine is present;
- sensing, by a second sensor, a degree of inclination of a machine main body of the work machine;
- and
- when a parking brake that brakes a travel unit of the machine main body is not activated, performing, by a controller, control to prevent the parking brake from being forgotten to be applied, on conditions that presence of the operator is not sensed and the machine main body is inclined.
