Patent number: 6883649Abstract: A closing system for use with a magneto-rheological (MR) damper. The closing system provides lubrication for a piston rod without a need for periodic replenishment. According to an embodiment of the present invention, a lubrication chamber of the closing system utilizes a carrier fluid portion of MR fluid present in a fluid reservoir of the damper as lubricant for a piston rod guide and the piston rod. A seal retainer comprised of a porous material acts as a selective barrier to the micro-particles in the MR fluid in the fluid reservoir, allowing the MR carrier fluid portion to pass through the porous seal retainer to the lubrication chamber while restraining the micro-particles in the fluid reservoir. The seal retainer thus acts as a filter to segregate the abrasive particles of the MR fluid and allows the MR carrier fluid portion of the MR fluid to continuously replenish the lubrication chamber and lubrication passage to lubricate the piston rod guide and piston rod.Type: GrantFiled: March 21, 2003Date of Patent: April 26, 2005Assignee: Delphi Technologies, Inc.Inventor: Saiman Lun

Patent number: 6880900Abstract: A target wheel cylinder pressure for each wheel is calculated according to an amount of braking operation performed by a vehicle operator. When anti-skid control is required, the wheel cylinder pressure is controlled to be equal to the target wheel cylinder pressure for reducing the brake slip of the wheel. When one of the rear-left and the rear-right wheels is anti-skid controlled, the target wheel cylinder pressure for the other wheel for which the anti-skid control is not performed is set to the same value as the target wheel cylinder pressure for the wheel for which the anti-skid control is performed. Linear valves are controlled based on the target wheel cylinder pressure, controlling the wheel cylinder pressures for the rear-left and the rear-right wheels to have substantially the same value.Type: GrantFiled: May 16, 2002Date of Patent: April 19, 2005Assignees: Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Masahiro Hara, Toshihisa Nihei, Naruyuki Matsui, Masahiro Matsuura

Patent number: 6814414Abstract: A device for preventing a rollback of a vehicle on an incline. The vehicle is equipped with a brake system, via which at least the braking pressure in the wheel brakes of a rear wheel is influenced in order to distribute the braking action between at least one front wheel and one rear wheel by actuating actuators assigned to the rear wheels so that a differential is set between the pressure of the front wheel and the rear wheel (e.g., an EBD braking). The device has a first arrangement for determining whether vehicle standstill is occurring due to braking where a differential in the braking pressure of the front wheel and the rear wheel has been set. The device also includes a second arrangement for determining whether the vehicle is rolling back from a standstill. If the second arrangement detects a vehicle rollback, the braking pressure in at least one rear wheel is increased to inhibit rollback.Type: GrantFiled: September 30, 1999Date of Patent: November 9, 2004Assignee: Robert Bosch GmbHInventors: Johannes Schmitt, Matthäus Koch
