摘要： A motor vehicle is equipped with an occupant seat belt system including a belt retractor having associated control mechanism such as a reel locking mechanism, a tension relieving mechanism, and/or a belt tensioning mechanism. The onset of a incipient wheel lock up condition sensed by the antilock brake system triggers the retractor associated mechanism so that restraint of the occupant is initiated in response to wheel condition independent of actuation by a sensed condition of vehicle deceleration.

摘要： A vehicle acceleration wheel slip control system monitors wheel slip and when a wheel slip condition becomes excessive as wheel slip increases during vehicle acceleration, engine torque output is initially reduced in accord with the rate of change in wheel slip. This derivative adjustment produces a significant correction to the engine torque output before the slip condition becomes very large. Thereafter, when the slip condition represents recovery from the excessive slip condition, the engine torque output is controlled in accord with the error in wheel slip from a desired value. This proportional adjustment maintains a desired slip value while maintaining stable acceleration slip control.
摘要翻译：车辆加速车轮滑移控制系统监测车轮滑移，并且当车辆加速期间车轮滑移增加时车轮滑动状况变得过大时，发动机扭矩输出最初根据车轮滑移的变化率而减小。在滑移条件变得非常大之前，该微分调整对发动机转矩输出产生显着的校正。此后，当滑动状态表示从过度滑动状态恢复时，根据期望值来控制发动机转矩输出与车轮滑移中的误差一致。该比例调整在保持稳定的加速滑移控制的同时保持期望的滑移值。

摘要： A system and method for determining the root cause of a fault in a vehicle system, sub-system or component using models and observations. In one embodiment, a hierarchical tree is employed to combine trouble or diagnostic codes from multiple sub-systems and components to get a confidence estimate of whether a certain diagnostic code is accurately giving an indication of problem with a particular sub-system or component. In another embodiment, a hierarchical diagnosis network is employed that relies on the theory of hierarchical information whereby at any level of the network only the required abstracted information is being used for decision making. In another embodiment, a graph-based diagnosis and prognosis system is employed that includes a plurality of nodes interconnected by information pathways. The nodes are fault diagnosis and fault prognosis nodes for components or sub-systems, and contain fault and state-of-health diagnosis and reasoning modules.

摘要： A method to assist steering of a vehicle equipped with an active steering system when operating in a reverse direction is provided. The method comprises monitoring vehicle operating characteristics and an operator steering input. Boundaries of a target region and a reference point are determined. A target steering angle range is calculated based upon the reference point and the target location. A controlled steering angle of the active steering system is corrected when the operator steering input is outside the target steering angle range. An aspect of the invention included determining the reference point comprising a point of intersection of a first vector and a second vector, the first vector parallel to and passing through a centerline of a rear axle of the vehicle and the second vector perpendicular to and passing through a centerline of an inside front steerable wheel of the vehicle.

摘要： A real-time vehicle dynamics estimation system that employs a vehicle parameter estimator, a vehicle condition detector and a rich steering input detector for estimating vehicle understeer coefficient and front and rear cornering compliances in real time. The vehicle parameter estimator receives a front wheel steering angle signal, a rear wheel steering angle signal, a vehicle lateral acceleration signal, a vehicle yaw rate signal and a vehicle speed signal, and employs a linear parameter estimation algorithm for estimating the understeer coefficient, and the front and rear corning compliance. The vehicle condition detector receives the front wheel steering angle signal, the rear wheel steering angle signal, the vehicle yaw rate signal and the vehicle speed signal, and disables the vehicle parameter estimator if the vehicle is not operating in a linear region. The rich steering input detector receives the front wheel angle signal, the rear wheel angle signal and the vehicle speed signal, and provides an output signal indicating whether the estimated vehicle parameters are reliable and are ready to be used.

摘要： A vehicle-trailer back-up control system that employs an active front steer sub-system. The system includes a smart hitch controller that receives a vehicle speed signal and a hand-wheel angle signal, and calculates a hitch angle command signal. The system further includes a hitch angle sensor that measures the hitch angle between the vehicle and the trailer that is compared to the hitch angle command signal to generate a hitch angle error signal. A PID control unit receives the hitch angle error signal, and generates a corrected road wheel angle signal based on proportional and derivative gains. The corrected road wheel angle signal is used to generate a motor angle signal that is applied to a steering actuator to be combined with the steering angle signal to generate the front wheel steering signal during a back-up maneuver.
