US Patent:

8366209, Feb 5, 2013

Filed:

Feb 8, 2010

Appl. No.:

12/658410

Inventors:

Dirk Wohltmann - Birmingham MI, US
Thomas Wolf - Barsinghausen, DE
Thomas Lenz - Lehrte, DE

Assignee:

WABCO GmbH - Hannover

International Classification:

B60T 13/68

US Classification:

303124

Abstract:

An improved braking system and brake control method for a vehicle, in particular a truck, utilizes at least one pressure line for carrying a medium from at least one pressurized medium source to a brake device, and a brake pedal for receiving brake commands from a vehicle driver and for operating a brake line, which can be connected to the brake device. A pilot control valve with accompanying measuring capability quantitatively determines the brake pressure demanded by the vehicle driver.

US Patent:

Filed:

Nov 10, 2005

Appl. No.:

11/272547

Inventors:

Ralph Kelly - Union KY, US
Dirk Wohltmann - Birmingham MI, US

International Classification:

B60T 13/74

US Classification:

303003000

Abstract:

A trailer brake system includes a full power hydraulic brake system that is electrically controlled by a system control unit. The trailer brake system includes a power unit that maintains a pressurized supply of hydraulic fluid and a brake control unit that is fluidly connected between the power unit and trailer wheel brake components. The power unit includes an electric motor driven pump and accumulator that is in fluid communication with a trailer supply reservoir. The brake control unit includes an inlet valve that is fluidly connected to the accumulator and an outlet valve that is fluidly connected to the trailer supply reservoir. The system control unit generates control signals to the power unit and brake control unit to respectively maintain a desired pressure level in the accumulator, and to apply the trailer wheel brake components through the brake control unit.

Filed:

Aug 25, 2008

Appl. No.:

12/229702

Inventors:

Dirk Wohltmann - Birmingham MI, US
Thomas Wolf - Bloomfield Hills MI, US

International Classification:

G06F 7/00

US Classification:

701 46, 701 45

Abstract:

A vehicle safety system comprising a vehicle stability-regulating system, one or more secondary safety components and an electronic interface. The electronic interface communicates with both the vehicle stability-regulating system and the secondary safety components. The electronic interface receives data from the vehicle stability-regulating system and controls the operating condition of the secondary safety components based thereon.

International Classification:

H01R 27/02
H01R 13/447
H01R 13/52
B60D 1/64

Abstract:

An electrical connector for transferring electrical signals between a tractor vehicle and a trailer vehicle is provided, the electrical connector including a connector plug and a connector socket in compliance with an industry standard. The connector socket includes a plurality of male contact terminals, and the connector plug includes a corresponding plurality of female contact terminals. The connector plug and the connector socket include a secondary electrical connection to support bidirectional data communication between a tractor vehicle and a trailer vehicle with greater bandwidth. The secondary electrical connection can include an additional electrical contact within a male part for engaging an additional electrical pin within a female part, wherein the male part and the female part are joined to, but laterally offset from, the connector plug and the connector socket. Alternatively, or in addition, the secondary electrical connection can include a conductive strip on an exterior annular surface of the connector plug and a corresponding electrical contact on an interior annular surface of the socket opening.
