1 17. Operation of Takao can be found in the flow diagrams on
2 Takao, pages 35-37.
3 18. Hunter is directed to an anti-skid control system for the
4 braking of vehicles. (Hunter, col. 1l. 12-13).
5 19. The apparatus of Hunter maintains wheel slip of the vehicle
6 in a region of values associated with a maximum coefficient
7 of road friction. (Hunter, col. 2, ll. 17-20).
8 20. The sense of slope versus slip curve is determined, and in a
9 braking application, a positive slope measurement causes
10 increased brake pressure and a negative or zero slope
11 measurement results in a reduction of brake pressure.
12 (Hunter, col. 2, ll. 28-33).
13 21. An object of the invention is to provide an improved anti-
14 skid control system employing only wheel acceleration input
15 data. (Hunter, col. 2, ll. 39-41).
16 22. It is also an object of the invention to provide an anti-skid
17 control system useful in preventing vehicle skidding under
18 high performance acceleration conditions as well as under
19 vehicle braking conditions. (Hunter, col. 2, ll, 42-46).
20 23. Lateral stability is inherently related to the stopping
21 problem. The best that can be done to preserve lateral
22 stability is to "keep the wheels rolling" (i.e., avoid lock-up).
23 It is appreciated that if the system can seek and hold the
24 peak of the μ-slip curve, the wheels will continue to rotate.
25 Note that loss of lateral stability is not to be confused with
26 pulling the vehicle in transverse direction as a result of
27 unbalanced road-tire forces. However, steerability, similarly
