Abstract
Abstract In an installation for the slippage limitation, respectively, prevention of driven wheels of a motor vehicle with an internal combustion engine controllable by an actuatable output adjusting member, an adjustable abutment for the output adjusting member serves for the purpose to so correct the driving torque of the internal combustion engine that the slippage is reduced to the permissive extent.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
An installation for limitation of slippage of driven wheels of a driver operated motor vehicle having an internal combustion engine controllable by a directly actuatable output-adjusting means having a gas pedal, comprising adjustble abutment means applying direct force to the output-adjusting means for transmitting via the gas pedal to the driver information concerning the status of driven wheel slippage, said adjustable abutment means being operable to reposition the gas pedal during the occurrence of abnormal slippage from a preselected gas pedal position corresponding to a first engine power output magnitude into a gas pedal position corresponding to a second power output magnitude different from said first magnitude in which the wheels possess substantially predetermined maximum permissive slippage.
Claim 2
Dependent Claim
117 words
An installation for limitation of slippage of driven wheels of a driver operated motor vehicle having an internal combustion engine controllable by a directly actuatable output-adjusting means having a gas pedal, comprising adjustble abutment means applying direct force to the output-adjusting means for transmitting via the gas pedal to the driver information concerning the status of driven wheel slippage, said adjustable abutment means being operable to reposition the gas pedal during the occurrence of abnormal slippage from a preselected gas pedal position corresponding to a first engine power output magnitude into a gas pedal position corresponding to a second power output magnitude different from said first magnitude in which the wheels possess substantially predetermined maximum permissive slippage.
Claim 3
Dependent Claim
13 words
An installation according to claim 1, wherein the abutment means is hydraulically controlled.
Claim 4
Dependent Claim
26 words
An installation according to claim 1, wherein the abutment means is operable to be overridden by means for applying an additional force to the abutment means.
Claim 5
Dependent Claim
37 words
An installation according to claim 1, wherein the abutment means is operable to adjust the output-adjusting means in a direction of an output reduction and in the direction of an output increase of the internal combustion engine.
Claim 6
Dependent Claim
13 words
An installation according to claim 4, wherein the abutment means is hydraulically controlled.
Claim 7
Dependent Claim
26 words
An installation according to claim 4, wherein the abutment means is operable to be overriden by means for applying an additional force to the abutment means.
Claim 8
Dependent Claim
13 words
An installation according to claim 6, wherein the abutment means is hydraulically controlled.
