Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
Drive slip control in a motor vehicle having switching means for detecting the speeds of rotation of driven and of non-driven wheels and having an actuator (29) for affecting the engine torque, the arithmetic mean value of the speeds of rotation of the driven wheels (HL, HR) being formed (amplifier 22), being compared in a comparator (19) to the speed of rotation of a non-driven wheel (V L , V R ) and in the event of a first differential threshold value (threshold value stage 24) being exceeded the actuator (29) for affecting the engine torque being actuated, characterized in that, furthermore, the speed of rotation of the non-driven wheels (V L , V R ) is compared to the arithmetic mean value of the driven wheels (comparators 44, 46) and in the event of a second differential threshold value (threshold value stages 45, 47) being exceeded the momentary value, present at the input of the comparator (19), of the speed of rotation of the non-driven wheel is retained until the differential threshold value is undershot again (sample-and-hold stage 54).
Claim 2
Dependent Claim
180 words
Drive slip control in a motor vehicle having switching means for detecting the speeds of rotation of driven and of non-driven wheels and having an actuator (29) for affecting the engine torque, the arithmetic mean value of the speeds of rotation of the driven wheels (HL, HR) being formed (amplifier 22), being compared in a comparator (19) to the speed of rotation of a non-driven wheel (V L , V R ) and in the event of a first differential threshold value (threshold value stage 24) being exceeded the actuator (29) for affecting the engine torque being actuated, characterized in that, furthermore, the speed of rotation of the non-driven wheels (V L , V R ) is compared to the arithmetic mean value of the driven wheels (comparators 44, 46) and in the event of a second differential threshold value (threshold value stages 45, 47) being exceeded the momentary value, present at the input of the comparator (19), of the speed of rotation of the non-driven wheel is retained until the differential threshold value is undershot again (sample-and-hold stage 54).
Claim 3
Dependent Claim
38 words
Drive slip control according to claim 1, characterized in that the momentary value is only retained if in addition the deceleration (differentiators 40, 42) of the non-driven wheel exceeds a predetermined threshold value (threshold value stages 41, 43).
Claim 4
Dependent Claim
41 words
Drive slip control according to claim 1 or 2, characterized in that the speed of rotation of the non-driven wheel (VL, VR) in each case rotating more slowly is fed to the input of the comparator (19) (minimum value stage 18).
Claim 5
Dependent Claim
40 words
Drive slip control according to one of claims 1 to 3, characterized in that the arithmetic mean value of the speeds of rotation of the non-driven wheels is evaluated as the speed of rotation of a non-driven wheel (VL, VR).
Claim 6
Dependent Claim
47 words
Drive slip control according to one of claims 1 to 3, characterized in that the actuator (29) for affecting the engine torque is only actuated if the engine speed (n M ) is above a predetermined speed of rotation (threshold value stage 27), preferably the idling speed.
