Abstract
A concrete mixer vehicle includes a controller that is configured to detect that an engine is in an idle condition and selectively shutdown the engine in response to detecting that one or more override conditions are met.
Claims20
A concrete mixer vehicle comprising:
- a chassis;
- an engine coupled to the chassis;
- a front axle coupled to the chassis;
- a rear axle coupled to the chassis;
- a cab coupled to the chassis, the cab defining an interior compartment;
- a drum assembly coupled to the chassis, the drum assembly including:
- a mixing drum defining an aperture and an internal volume;
- a charge hopper positioned proximate the aperture;
- and
- a chute positioned proximate the aperture, beneath the charge hopper;
- a hopper actuator positioned to move the charge hopper between a first position and a second position, the first position facilitating loading materials into the internal volume of the mixing drum via the charge hopper through the aperture, the second position facilitating discharging the materials from the internal volume, through the aperture, and to the chute;
- and
- a controller in communication with the engine, the drum assembly, and the hopper actuator, the controller being configured to:
- detect that the engine is in an idle condition;
- and
- selectively shutdown the engine in response to determining that one or more override conditions are met.

- a drum assembly coupled to the chassis, the drum assembly including:
- a mixing drum defining an aperture and an internal volume;
- a charge hopper positioned proximate the aperture;
- and
- a chute positioned proximate the aperture, beneath the charge hopper, wherein the chute includes a main chute and an extension chute pivotably coupled to the main chute;
- a hopper actuator positioned to move the charge hopper between a first position and a second position, the first position facilitating loading materials into the internal volume of the mixing drum via the charge hopper through the aperture, the second position facilitating discharging the materials from the internal volume, through the aperture, and to the chute;
- and
- a controller in communication with the engine, the drum assembly, and the hopper actuator, the controller being configured to:
- detect that the engine is in an idle condition;
- and
- initiate an idle shutdown process where the engine is selectively shutdown in response to determining that idle shutdown conditions are met, wherein the idle shutdown conditions include (a) a slump pressure being below a slump pressure threshold, (b) a speed of the mixing drum is between a lower speed threshold and an upper speed threshold, and (c) the main chute and the extension chute are in a storage configuration.

An idle shutdown method for a concrete mixer vehicle, the idle shutdown method comprising:
- detecting that an engine is in an idle condition;
- and
- determining if idle shutdown conditions are met, wherein the idle shutdown conditions include (a) a slump pressure being below a slump pressure threshold, (b) a speed of a mixing drum is between a lower speed threshold and an upper speed threshold, and (c) a main chute and an extension chute are in a storage configuration;
- in response to determining that the idle shutdown conditions are met, shutting down the engine.
