Abstract: A technique for acoustically communicating through existing air brake lines between a tractor and a trailer. The diagnostic status of the trailer antilock system is communicated via acoustic signals from the trailer antilock system through the air brake lines of the trailer and into the tractor air brake line. A piezo crystal located in the tractor air brake line converts the acoustic signal into an electrical signal which may be used to illuminate a lamp providing a display on the tractor dashboard.

Abstract: A displacement sensor utilizes a Hall effect sensor and a magnet, but has an extended range compared to conventional Hall effect displacement sensors. Relative movement between the sensor and the magnet is defined such that the path of movement is not parallel to an axis between the north and south poles of the magnet. Thus, the total path of movement is greater than in the prior art. One particularly preferred application for this sensor is in a disc brake, and as part of an adjustment mechanism for adjusting the position of the disc brake pistons. The displacement sensor is relatively small, and thus can be accommodated in the crowded environment of the disc brake adjustment mechanism. On the other hand, with the inventive large range displacement sensor, the simple and compact sensor can provide adequate measurement of the displacement of the piston.

Abstract translation: 位移传感器利用霍尔效应传感器和磁体，但与常规霍尔效应位移传感器相比具有扩展的范围。 传感器和磁体之间的相对移动被定义为使得运动路径不平行于磁体的北极和南极之间的轴线。 因此，总的运动路径比现有技术中的大。 该传感器的一个特别优选的应用是盘式制动器，并且作为用于调节盘式制动器活塞的位置的调节机构的一部分。 位移传感器相对较小，因此可以容纳在盘式制动器调节机构的拥挤环境中。 另一方面，利用本发明的大范围位移传感器，简单紧凑的传感器可以提供活塞位移的适当测量。

Abstract: A drive train assembly including an electric motor mounted to the frame of the motor vehicle and a trailing arm. The trailing arm is attached to the frame of a motor vehicle such that a pivot point is common to an axis of rotation of a shaft of the electric motor. The electric motor drives a drive mechanism supported by the trailing arm to drive a wheel suspended at a distal end of the trailing arm. The trailing arm pivots about the axis of rotation of the motor shaft thereby reducing the suspended mass of the vehicle and improving ride and handling characteristics.

Abstract: A system for controlling multiple vehicle includes a twelve volt (12V)/forty-two volt (42V) battery power distribution system that provides direct current. The system converts single phase alternating current to multiple phase alternating current to simultaneously power multiple vehicle systems. A single pulse width modulation generator converts the direct current from the 12V/42V battery power distribution system to alternating current. This provides one power supply path of alternating current, which has a first phase. A splitter device splits the one power supply path of alternating current into three power paths. A lead/lag circuit is used to shift the alternating current of the second path to a second phase different than the first phase of the first power supply path. A second lead/lag circuit for shifts the alternating current of the third path to a third phase different than the first phase or the second phase. This creates a three-phase alternating current power from a single direct current source. The three-phase alternating current is used to power a plurality of induction motors that operate multiple vehicle systems.

Abstract: A pair of tension cables are positioned around cams attached to the lower control arms of a vehicle suspension. Each tension cable includes a tension damper responsive to tension in the tension cables. Each tension damper includes a cylinder containing a fluid and a piston including at least one orifice attached to a rod. The piston divides the cylinder into a first and second compartment. The rod in connected to the tension cable. When the tension cable pulls on one end of the rod, the piston is pulled towards the tension cable. The fluid creates resistance in the tension damper as the fluid moves through the orifice from one compartment to the other compartment, damping vehicle roll. Control of the tension dampers can be passive, semi-active, or active.

Abstract: A vehicle brake assembly includes a sensor that detects the amount of movement of certain components within the brake assembly. In the preferred embodiment, a rotary sensor is coupled directly with the generally S-shaped cam member and provides signals that indicate the total amount of rotary movement of the cam member during braking applications. These signals provide information indicative of the amount of slack or stroke during braking applications and provide indications of the conditions of brake linings associated with the brake shoes within the brake assembly. The sensor information preferably is communicated to a vehicle operator in a manner that indicates whether an inspection or maintenance of the braking system is advisable

Abstract: A vehicle data storage system is provided which includes a plurality of sensors for sensing vehicle operating conditions, such as engine temperature. A control module receives the vehicle operating conditions and translates the vehicle operating conditions into vehicle information. A portable hand held computing device, such as a Handspring® or Palmpilot®, has a data storage device or memory that receives the vehicle information. The data storage device is limited by a particular memory capacity. A secondary storage device receives the vehicle information from the data storage device from the portable hand held computing device when the memory capacity reaches a desired memory capacity level, such as when there is only 10% of the memory left in the data storage device. Additionally, one of the vehicle operating conditions in one of the subsystem control modules may comprise a triggering event. The triggering event may be detecting a high engine temperature in an engine temperature sensor. The subsystem control module then produces a request signal for event data in response to the triggering event. A memory buffer stores the vehicle information from all of the subsystem control modules. The event data is defined by a first predetermined time before the triggering event to a second predetermined time after the triggering event so that the data surrounding the triggering event resides in the memory buffer. The data in the memory buffer is written over by new data unless a request signal is received. A secondary storage device receives the event data in response to the request signal.

Abstract: A brake shoe assembly includes a backing plate and a brake lining. The brake lining has an interface surface abutting the backing plate and a frictionally engaging surface that frictionally contacts a vehicle. The brake lining is provided with a temperature measuring system embedded therein which may measure the temperature directly on the frictionally engaging surface of the brake lining material by way of a heat pipe. The temperature measuring device communicates with a control that activates a signal when a predetermined abnormal degree of heat is generated on the frictionally engaging surface of the brake lining. Thus, a fault in the braking mechanism is indicated.
