Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
61 words
Set-point adjuster for the production of an electrical control variable, especially for a brake pedal in a motor vehicle for controlling an electrical brake system, characterised by a parallel connection and subsequent evaluation of at least two sensors (1, 2) which operate according to different principles, each of which produces an electrical signal and one of which is a force sensor.
Claim 2
Dependent Claim
61 words
Set-point adjuster for the production of an electrical control variable, especially for a brake pedal in a motor vehicle for controlling an electrical brake system, characterised by a parallel connection and subsequent evaluation of at least two sensors (1, 2) which operate according to different principles, each of which produces an electrical signal and one of which is a force sensor.
Claim 3
Dependent Claim
21 words
Set-point adjuster according to claim 1, characterised by the parallel connection of a displacement sensor (1) and a force sensor (2).
Claim 4
Dependent Claim
33 words
Set-point adjuster according to claim 2, characterised in that the output signals of the displacement sensor (1) and the force sensor (2) are filtered and/or digitised in separate electronic input circuits (3, 4).
Claim 5
Dependent Claim
44 words
Set-point adjuster according to claims 1 to 3, characterised in that there are arranged downstream of the input circuits (3, 4) main electronic circuits (5, 6) which exchange information on the input signals via lines (7, 8) and check the sensor signals for plausibility.
Claim 6
Dependent Claim
32 words
Set-point adjuster according to claims 1 to 4, characterised in that the input circuits (3, 4) and the main circuits (5, 6) are supplied from separate voltage sources (Ui, U ll ).
Claim 7
Dependent Claim
35 words
Set-point adjuster according to claims 1 to 5, characterised in that, in the normal fault-free state, the signal of only one sensor, namely the force sensor (2), is applied to a common output line (9).
Claim 8
Dependent Claim
41 words
Set-point adjuster according to claims 1 to 6, characterised in that the main circuits (5, 6) contain devices for checking the rate of change in the input signals, which devices check the input signals for too rapid a rise or fall.
Claim 9
Dependent Claim
30 words
Set-point adjuster according to claims 1 to 7, characterised in that the main circuits (5, 6) contain devices for checking the level of the input signals in the unbraked state.
Claim 10
Dependent Claim
30 words
Set-point adjuster according to claims 1 to 8, characterised in that the main circuits (5, 6) contain devices for checking the constancy of the input signals in the braked state.
Claim 11
Dependent Claim
30 words
Set-point adjuster according to claim 9, characterised in that the main circuits (5, 6) contain a device for briefly reducing the braking force in order to test the driver's reaction.
Claim 12
Dependent Claim
36 words
Set-point adjuster according to claims 1 to 10, characterised in that the main circuits (5, 6) contain devices for checking the relationship of the two input signals with one another over the range of brake values.
