    摘要： A vehicle control system that selectively provides rear-wheel steering to prevent a vehicle-trailer from jackknifing during a back-up maneuver. The system senses a steering angle of the vehicle, a speed of the vehicle and a hitch angle between the vehicle and the trailer. The system calculates an equilibrium hitch angle that is a steady-state hitch angle position based on the steering angle and the vehicle speed, and a pseudo-equilibrium hitch angle that is a steady-state hitch angle at a maximum rear-wheel steering input based on the steering angle and the vehicle speed. The system then determines whether the rear-wheel steering should be provided based on a predetermined relationship between the sensed hitch angle, the equilibrium hitch angle and the pseudo-equilibrium hitch angle.

It harnesses the power of material capable of transporting specimen by capillary action, sandwich complex technique with a mobile anti-hCG antibody conjugated with a specific marker, hCG or derivative, and an immobile anti-hCG antibody, and a highly sensitive detection system for the marker or change of conditions of the marker. It may only comprise sandwich complex technique and detection system. It may simply comprise immobile anti-hCG antibody and detection system. It also can comprise immobile anti-hCG antibody and mobile standard hCG or derivative conjugated with a specific marker, and the latter competes against counterpart from specimen for a limited amount of anti-hCG antibody.

    摘要： A method is provided for determining an adhesive condition of a surface of a vehicle road using a statistical pattern recognition technique. A plurality of probability distribution functions is provided representing respective adhesive effects between the vehicle tire of a driven vehicle and the vehicle road. An index is calculated which represents a vehicle understeer characteristic. Probability analysis is applied for each of the road surface adhesive conditions as a function of the index. Each probability analysis is recursively updated. A likelihood factor is determined for each road surface adhesive condition as a function of each respective recursively updated probability analysis. Each respective road surface adhesive condition has a respective likelihood factor that identifies the likelihood of the road surface having the respective adhesive condition as a function of the index. The identified adhesive condition of the road surface is input into a vehicle control process.

    摘要： A method for controlling an assisted steering maneuver in an electric power steering (EPS) system includes modeling steering dynamics during a torque overlay operation to generate a dynamic steering model (DSM), measuring vehicle operating values, and detecting a driver intervention in the torque overlay operation based on the DSM and the vehicle operating values. The torque overlay operation is overridden when driver intervention is detected, allowing the driver to regain control of the steering maneuver. A vehicle includes a steering wheel, a steering assist mechanism, and an EPS system having an electronic control unit (ECU) adapted to determine a present intent of a driver of the vehicle to interrupt application of the TOC based on a vehicle operating value transmitted by the driver to the steering wheel. The ECU is operable for interrupting the torque overlay operation when the present intent of the driver is determined.

    摘要： A method is provided for determining a state of a road condition using a linear model-based estimation technique. Two vehicle reference models are defined to represent vehicles operating under non-slippery and slippery road surfaces respectively. An index that reflects the vehicle understeer characteristics is also defined. Indices are determined from the reference models under the non-slippery road surface, the slippery road surface, and from vehicle sensor measurement, respectively. A first root mean square deviation is calculated between the index of reference model under non-slippery road surface and the index calculated based on sensor measurement. A second root mean square deviation is calculated between the index of reference model under slippery road surface and the index calculated based on sensor measurement. A probability analysis is applied as a function of probability density functions for identifying the condition of the road surface between a non-slippery road surface and a slippery road surface.

    摘要： A vehicle curve speed control system (10) adapted for use with a vehicle (12) having an operator (14), includes a map database (16) representing a current vehicle path, and a locator device (20) communicatively coupled to the database (16) and configured to determine the location of the vehicle (12) on the path. The system (10) further includes a controller (36) configured to identify approaching curve points of a curve (18a) in terms of curvature or radius, and determine a desired speed profile based on operator preference and/or vehicle characteristic input. An acceleration profile is determined, based on the current vehicle speed, and desired speed profile. An acceleration/deceleration command at the present control loop is modified towards achieving an optimal curve speed, and is delivered to either a brake or acceleration module (40,42) to automatically accelerate or decelerate the vehicle (12) accordingly.
