Abstract
A device for controlling the speed of an internal combustion engine in a working tool including a device for recognizing a special operating state of the working tool. By way of example, a special operating state can be taken to mean the start-up of the internal combustion engine or a danger that can occur when the user lets go of said working tool or the tool tips over. An adjustment device adjusts the engine speed of the internal combustion engine to a safety speed that is below the operating speed of the internal combustion engine when the special operating state is recognized.
Claims8
An arrangement for controlling the speed of an internal combustion engine in an implement, comprising:
- a recognition device which is configured to recognize a special operating state of the implement brought about by an action from outside the implement;
- and
- an adjusting device which can be activated by the recognition device and which is configured to adjust the engine speed to a safety speed below an operating speed of the internal combustion engine, wherein the special operating state that is recognized is a state in which an angular setting of the implement is outside of a permissible range.
An arrangement for controlling the speed of an internal combustion engine in an implement, comprising:
- a recognition device which is configured to recognize that the engine is started;
- and
- an adjusting device which can be activated by the recognition device and which is configured to adjust the engine speed to a safety speed below an operating speed of the internal combustion engine, wherein the recognition device is configured to recognize a rise in speed of the engine from standstill.
An arrangement for controlling the speed of an internal combustion engine in an implement, comprising:
- a recognition device which is configured to recognize that the engine is started;
- and
- an adjusting device which can be activated by the recognition device and which is configured to adjust the engine speed to a safety speed below an operating speed of the engine, wherein the recognition device is configured to determine that the engine has started by recognizing that an ignition system of the engine is supplied with power, and wherein, upon recognizing that the internal combustion engine is supplied with power, the recognition device activates the adjusting device to adjust engine speed to the safety speed.
An arrangement for controlling the speed of an internal combustion engine in an implement which can be steered using a holding handle, comprising:
- a recognition device which is configured to recognize an operating state of the implement which is brought about by action from outside the implement;
- and
- an adjusting device which can be actuated by the recognition device and which is configured to adjust the engine speed to a safety speed below an operating speed of the internal combustion engine;
- the special operating state being a state in which the implement is not steered correctly;
- wherein the recognition device has a sensor arrangement on the holding handle which is configured to automatically recognize whether the implement is being steered correctly.
An arrangement for controlling the speed of an internal combustion engine in a implement which can be manually guided using a holding handle, the arrangement comprising:
- a recognition device which is configured to recognize a special operating state of the implement which is brought about by action from outside the implement, the special operating state being a state in which the soil compaction device is not guided correctly;
- and
- an adjusting device which can be actuated by the recognition device and which is configured to adjust the engine speed to a safety speed below an operating speed of the internal combustion engine;
- wherein the recognition device has a sensor arrangement on the holding handle which is configured to automatically recognize whether the implement is being guided correctly, and wherein the recognition device has a device that determines the angular position of the implement and, when a predetermined position limit is exceeded, recognizes the special operating state.
An arrangement for controlling the speed of an internal combustion engine in a implement which can be manually guided using a holding handle, the arrangement comprising:
- a recognition device which configured to recognize a special operating state of the implement which is brought about by action from outside the implement, the special operating state being a state in which the soil compaction device is not guided correctly;
- and
- an adjusting device which can be actuated by the recognition device and which is configured to adjust the engine speed to a safety speed below an operating speed of the internal combustion engine;
- wherein the recognition device has a sensor arrangement on the holding handle which is configured to automatically recognize whether the implement is being guided correctly, and
- wherein the implement is a soil compaction device comprising one of a rammer and a strike hammer.
