Title:
BRAKE DIAGNOSIS DEVICE FOR AN AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/1997/049591
Kind Code:
A1
Abstract:
A brake diagnosis device for an automobile for securing the safety of a brake and productivity of mining and quarrying and detecting a wide range of data including a history, the device comprising oil temperature detecting means (23) for detecting a cooling oil temperature (d) just after the brake is cooled, duration time calculating means for calculating a duration time (t) for maintaining the cooling temperature on receipt of the cooling oil temperature (d), and first adding means (31a) having in advance a first matrix (A) that is vertically and horizontally divided for not only each predetermined duration temperature area but also each predetermined duration time area for receiving a cooling oil temperature (d) from either of the oil temperature detecting means and duration time calculating means and a duration time (t) from the duration time calculating means, adding a frequency (An) to a division of the first matrix (A) including the cooling oil temperature (d) and the duration time (t), and freely outputting an added value to an external source.
