Title: Method and system for controlling brake pressure under low mu braking surface conditions in a vehicular abs
Inventor: YOUNGBLOOD RICHARD JOSEPH
IPC: B60T8/66
Filed: 1993-04-27
Granted: 1999-04-06
Abstract: Method  and  system  for  reducing  the  brake pressure  rise rate  under  low  Mu  braking  surface conditions by utilizing a vehicle reference speed and a fixed bleed rate to determine if the wheels are being over-braked.   When over-braking occurs,  the pressure rise rate is restricted by not allowing an ABS valve (10)  to  go  into  an Apply  state  (approximately  100 psi/sec.), regardless of wheel acceleration levels.  A Ramp state is used in place of the Apply state and the pressure rise is therefore limited to approximately 30 psi/sec. to improve wheel control.  The Ramp duty cycle is also modified to provide the smallest pressure steps possible with the current valve hardware.

Abstract: An evaporator coil mounting pin which is operable to retain the evaporator coil adjacent the rear interior cabinet wall of the refrigerator cabinet to prevent the evaporator coil from accidentally slipping off the mounting pin during assembly of the refrigerator.   The mounting pin provides both vertical and horizontal support for the evaporator coil,  and includes a refrigerator cabinet engaging portion which extends into the refrigerator cabinet and positively locks the mounting pin in place.  The mounting pin further includes a stop, a disc-shaped baseplate and an upstanding shoulder, the upstanding shoulder extending between the stop and the baseplate along a portion of the length of the mounting pin.  The evaporator coil is supported by the upstanding shoulder and is positioned between the stop and the refrigerator cabinet,  and is thus prevented from being unintentionally displaced from the mounting pin.  The terminal end of the mounting pin provides a support surface with a fastener receiving aperture formed therein for mounting of the evaporator cover,  which forms the rear surface of the food storage compartment.  Self threading screws or other appropriate fasteners are used to attach the evaporator cover to the mounting pin.
