Abstract
Abstract The invention relates to a method for defining the initiation sensitivity of an automatic braking procedure, in which method the threshold value for the initiation of an automatic braking procedure is reduced as a function of the pedal distance which has been traversed. The object of the invention is to ensure that in the event of actuation of the brake shortly after the automatic braking procedure has terminated, the automatic braking procedure is again initiated rapidly and easily. For this purpose, the initiation threshold value for the automatic braking procedure is reduced within a time period after the satisfaction of the interruption criterion.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
128 words
Method for controlling the initiation sensitivity of a vehicle automatic braking process of the type wherein, when a first initiation threshold value for the actuation speed of a vehicle brake pedal is exceeded, a brake pressure higher than that which corresponds to a position of the brake pedal is generated during the automatic braking procedure, and wherein automatic braking is terminated when an interruption criterion is satisfied, said method comprising: detecting a termination of an automatic braking procedure; measuring a predetermined time interval commencing upon termination of said automatic braking procedure; after said termination of said automatic braking procedure, providing a second initiation threshold value for initiation of automatic braking during said predetermined time interval, said second initiation threshold value being smaller than said first initiation threshold value.
Claim 2
Dependent Claim
128 words
Method for controlling the initiation sensitivity of a vehicle automatic braking process of the type wherein, when a first initiation threshold value for the actuation speed of a vehicle brake pedal is exceeded, a brake pressure higher than that which corresponds to a position of the brake pedal is generated during the automatic braking procedure, and wherein automatic braking is terminated when an interruption criterion is satisfied, said method comprising: detecting a termination of an automatic braking procedure; measuring a predetermined time interval commencing upon termination of said automatic braking procedure; after said termination of said automatic braking procedure, providing a second initiation threshold value for initiation of automatic braking during said predetermined time interval, said second initiation threshold value being smaller than said first initiation threshold value.
Claim 3
Dependent Claim
31 words
Method according to claim 1 wherein said second initiation threshold value is provided only if the interruption criterion is satisfied within a first time interval after satisfaction of the initiation criterion.
Claim 4
Dependent Claim
51 words
Method according to claim 2 wherein the second initiation threshold value is provided only if the predetermined time interval has not yet elapsed since the satisfaction of the interruption criterion, at a point in time when the first time interval has not yet elapsed since the satisfaction of the initiation criterion.
Claim 5
Dependent Claim
23 words
Method according to claim 2 wherein the second initiation threshold value is reduced by a factor relative to said first initiation threshold value.
Claim 6
Dependent Claim
15 words
Method according to claim 4 herein the factor has a value between 0.4 and 0.8.
Claim 7
Dependent Claim
13 words
Method according to claim 4 wherein the factor has the value of 0.5.
Claim 8
Dependent Claim
29 words
Method according to claim 4 wherein the factor is a function of the time elapsed since one of: satisfaction of the interruption criterion, and satisfaction of the initiation criterion.
Claim 9
Dependent Claim
16 words
Method according to claim 2 wherein the first time interval is between 0 and 5 seconds.
Claim 10
Dependent Claim
28 words
Method according to claim 8 wherein said length of the first time interval is a function of one of vehicle speed and vehicle deceleration during the braking procedure.
Claim 11
Dependent Claim
19 words
Method according to claim 1 wherein the length of the predetermined time interval is between 0 and 5 seconds.
Claim 12
Dependent Claim
28 words
Method according to claim 10 wherein the length of the predetermined time interval is a function of one of vehicle speed and vehicle deceleration during the braking procedure.
Claim 13
Dependent Claim
26 words
Method according to claim 1 wherein a withdrawal of the brake pedal in the direction of its unactuated rest position is employed as the interruption criterion.
Claim 14
Dependent Claim
23 words
Method according to claim 1 wherein the attainment of the unactuated rest position by the brake pedal is employed as the interruption criterion.
