Abstract
A refuse vehicle including an electric motor powered by a battery, a hydraulic pump driven by the electric motor, a hydraulic actuator powered by the hydraulic pump, and one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to: determine a target cycle time for the hydraulic actuator, and control a speed of the electric motor to achieve the target cycle time.
Claims20
A refuse vehicle comprising:
- an electric motor powered by a battery;
- a hydraulic pump driven by the electric motor;
- a hydraulic actuator powered by the hydraulic pump;
- and
- one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
- determine a target cycle time for the hydraulic actuator;
- and
- control a speed of the electric motor to achieve the target cycle time.
A refuse vehicle comprising:
- an electric motor;
- a hydraulic pump driven by the electric motor;
- a hydraulic actuator powered by the hydraulic pump;
- and
- one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
- receive route information;
- determine a target cycle time for the hydraulic actuator based on the route information so that the hydraulic actuator is ready to be employed upon arrival at a next stop;
- and
- control a speed of the electric motor to achieve the target cycle time.
A refuse vehicle comprising:
- a first electric motor;
- a first hydraulic pump driven by the first electric motor;
- a packer actuator powered by the first hydraulic pump;
- a second electric motor;
- a second hydraulic pump driven by the second electric motor;
- a grabber assembly actuator driven by the second hydraulic pump;
- and
- one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices configured to store instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
- determine a packer target cycle time for the packer actuator;
- determine a grabber target cycle time for the grabber assembly;
- control a speed of the first electric motor to achieve the packer target cycle time;
- and
- control a speed of the second electric motor to achieve the grabber target cycle time.
