  • Patent number: 6173882
    Abstract: A workpiece is held at a welding station by several clamps during welding. After welding, the workpiece is transferred to a checking station where a determination is made of the actual location of critical points on the workpiece. The actual critical point locations are compared with ideal critical point locations to determine if there is any error in the manner in which the workpiece was held by the clamps. If an error is determined, one or more of the clamps are adjusted to compensate for the error when holding a subsequent workpiece for welding. Apparatus is also provided for carrying out the method of this invention.

  • Patent number: 6167777
    Abstract: The tiltable component in a tilt type vehicle steering column can be locked in selected positions of adjustment by an external locking mechanism that includes an elongated rod having pivot connections with the stationary and movable components of the column. A rotatable locking sleeve encircles the rod to form a rigid connection between the rod and one of the pivot connections. Meshed teeth on the rod and sleeve prevent the rod from moving in the longitudinal direction. By rotating the sleeve on the rod it is possible to shift the teeth out of mesh, such that the rod can move longitudinally to set the movable component of the steering column in a new selected position of adjustment.

  • Patent number: 6161284
    Abstract: Coolant pump service in a crowded engine compartment is provided by forming the side wall of the pump drive pulley with a centralized and radially lobed opening which can accommodate the radial arms of the drive hub that are normally connected by screws to the pulley side wall. The drive hub is fixed to the outboard end of the coolant pump drive shaft that extends through the housing of the pump that is removably secured by screws to the block of an internal combustion engine. The pump impeller is mounted on the inboard end of the drive shaft for fluid pumping operation in a coolant-receiving cavity in the coolant circuit of the engine. In the event of interference, which prevents or hampers the removal of the pulley axially from the drive shaft, the hub screws are removed and the pulley is turned into alignment with the lobes of the opening so that the pump housing screws are accessible.

  • Patent number: 6158763
    Abstract: An automotive safety airbag installation includes a padded instrument panel having a U-shaped tearable seam in the panel skin, and a concealed airbag assembly having two hinged lids spaced from the instrument panel internal surface, such that during inflation of the airbag the lids swing outwardly to cause a flap-like section of the panel to deflect upwardly for expansion of the airbag into the passenger compartment. One of the lids closes a gap between the airbag and instrument panel to guide the airbag through the instrument panel and to protect both the airbag and the instrument panel from damage. The padded instrument panel is designed to achieve good shock absorbing action when struck by a human body, in the absence of airbag deployment.

  • Patent number: 6155365
    Abstract: A hybrid electric powertrain system is provided including a transmission for driving a pair of wheels of a vehicle and a heat engine and an electric motor/generator coupled to the transmission. A friction brake system is provided for applying a braking torque to said vehicle. A controller unit generates control signals to the electric motor/generator and the friction brake system for controllably braking the vehicle in response to a drivers brake command. The controller unit determines and amount of regenerative torque available and compares this value to a determined amount of brake torque requested for determining the control signals to the electric motor/generator and the friction brake system.

  • Patent number: 6155544
    Abstract: The coil spring of a vehicle shock absorber can be seated on an elastomeric sound isolator pad whose spring engagement surface has plural slot-like depressions evenly spaced around the pad circumference. These slot-like depressions form raised ribs that provide the contact surfaces for the lowermost convolution of the coil spring. Each rib can readily deform under the spring force. Side surfaces of the ribs can act as heat-dissipating surfaces. The slot construction allows the pad to be formed out of a reasonably high durometer and highly wear-resistant elastomer without adversely affecting the desired rib deflection.

  • Patent number: 6151537
    Abstract: A method for determining the tractive effort required at the wheels of a vehicle for a given set of operating parameters by taking into account a plurality of variables which affect vehicle performance. A total grade effort value is determined which represents the force required to move the vehicle due to the grade of the surface on which the vehicle is expected to travel. An approximate total rolling effort value is also determined which is representative of the force required to move the vehicles due to the hysteresis of the vehicle's tires. Lastly, an aerodynamic influence factor is determined which represents the total air resistance of the vehicle and any implement such as a trailer being towed by the vehicle. These factors are summed to produce a tractive effort value representative of the total tractive effort that would be required to move the vehicle at a designated speed.

  • Patent number: 6141620
    Abstract: A system for remote testing of a plurality of vehicles on a test track includes a plurality of guide wires and position transponders embedded in the track. Each vehicle to be tested includes an onboard vehicle controller (VCON) which in turn includes various servo components for operating the steering wheel, shift lever, brake and accelerator pedals of the vehicle. A base computer receives desired missions from an operating computer, and the base computer loads a respective mission into each VCON via an rf link. Then, the base computer monitors the vehicles for proper, safe operation. The VCONs execute the missions loaded by the base station and periodically report their status to the base computer.

  • Patent number: 6137992
    Abstract: A radio frequency audio distortion measurement system for a motor vehicle radio. The system includes a generator that generates test RF signals and transmits the signals to the motor vehicle radio through a wireless communication link. The system includes a controller coupled to the generator that controls the transmission of the RF signals to the radio. The system also includes a distortion analyzer coupled to the RF receiver and the controller that senses and analyzes the audio distortion caused by motor vehicle system components, such as motor vehicle electrical and electronic system components, in response to commands output from the controller. The system of the present invention thereby provides an objective way of analyzing audio distortion caused by radiated conducted and/or coupled interference from electrical and electronic systems in a controlled test environment.

  • Patent number: 6134895
    Abstract: A method of air conditioning system temperature control for a motor vehicle is disclosed. The method includes the steps of measuring an air conditioning compressor discharge pressure and determining if the discharge pressure is greater than a predetermined maximum pressure. The method also includes the step of beginning a forced recirculated air mode if the discharge pressure is greater than the predetermined maximum pressure. The method further includes the steps of determining if the air conditioning system is already in a forced recirculated air mode if the discharge pressure is less than the predetermined maximum pressure, and determining if the discharge pressure is less than a predetermined acceptable pressure if the air conditioning system is already in a forced recirculated air mode. The method still further includes the step of beginning an outside air mode if the discharge pressure is less than the predetermined acceptable pressure.
