Residual Or Remanent Magnetism Control Patents (Class 307/101)
  • Patent number: 10131346
    Abstract: A method for diagnosing demagnetization of a motor of a vehicle can accurately diagnose an irreversible demagnetization state of a permanent magnet of a traction motor or a hybrid starter-generator (HSG) without additional hardware, while minimizing influence of irreversible demagnetization of the permanent magnet of the traction motor or the HSG on vehicle performance. The method includes acquiring operating state information of the motor, determining whether a diagnosis entrance condition including a state in which the motor performs an electricity generating operation is satisfied based on the acquired operating state information of the motor, acquiring a direct current (DC) value in diagnosis, and determining whether irreversible demagnetization occurs by comparing the acquired DC value in diagnosis with a pre-stored DC current value in a normal state of the permanent magnet.

  • Patent number: 6262495
    Abstract: A two dimensional periodic pattern of capacitive and inductive elements defined in the surface of a metal sheet are provided by a plurality of conductive patches each connected to a conductive back plane sheet between which an insulating dielectric is disposed. The elements acts to suppress surface currents in the surface defined by them. In particular, the array forms a ground plane mesh for use in combination with an antenna. The performance of a ground plane mesh is characterized by a frequency band within which no substantial surface currents are able to propagate along the ground plane mesh. Use of such a ground plane in aircraft or other metallic vehicles thereby prevents radiation from the antenna from propagating along the metallic skin of the aircraft or vehicle. This eliminates surface currents between the antenna and the ground plane thereby reducing power loss and unwanted coupling between neighboring antennae.

  • Patent number: 6157881
    Abstract: An improved deployment method for a vehicular supplemental restraint system, wherein the timing of restraint deployment in response to a detected a rear impact of sufficient severity is based on the attainment of a predefined characteristic by a signal representative of the slope of a filtered acceleration signal. As a result, the deployment of the restraints is accurately timed for any given crash event, and provides consistent performance regardless of the nature of the impact. The deployment is conditioned upon (1) detection of a predefined level of severity, and (2) a subsequent reduction in the slope of a filtered acceleration signal to a predefined level. Preferably, the predefined level of severity--i.

  • Patent number: 6157294
    Abstract: A vehicle control system for detecting an obstacle present ahead on the road in the course of travel of a vehicle, comprising a first laser radar mounted on the vehicle which emits an electromagnetic beam to detect the obstacle present ahead on the road, and second and third laser radars which measures distances between the first laser radar and the road surface at different angles. The system determines whether the first laser radar is mounted on the vehicle such that the laser beam central axis is horizontal or inclines upward or downward relative to the road surface or vehicle body, based on the distances, a height of the first laser radar from the road surface, the angles at which the distances are measured and reference values. The system may correct the inclination if determined. With the arrangement, the system ensures detection of an obstacle on the road without fail and conduction of a desired obstacle avoidance control.

The primary oscillations which are produced when the vehicle is being operated are determined. Data for secondary oscillations are acquired from the primary oscillations and are converted at least in part into vibration oscillations which can be perceived through the human body. At least one of the components of the vehicle body is excited using the vibration oscillations, the vibration oscillations being placed in an interference relationship with the primary oscillations. In particular, the steering wheel is also excited so as to undergo mechanical vibration oscillations.

    Abstract: A wireless switching system includes a central transmitter unit which generates a plurality of electromagnetic frequencies. A plurality of switches within the electromagnetic field each selectively open and close a resonant circuit having a unique resonant frequency. When the user activated switch closes its associated resonant circuit, the resonant circuit consumes energy from the electromagnetic field at its resonant frequency. The central transmitter unit detects this energy consumption and the frequency at which the energy consumption occured and consequently activates a vehicle function associated with the closed user activated switch.

  • Patent number: 6148251
    Abstract: A steering wheel control system (10) that employs a method for passing push-button commands from a steering wheel to a vehicle system where the method is not dependant upon the contact resistance of a sliding contact (32) located in the steering wheel column. The control system (10) uses a steering wheel electronics assembly (20) to generate tones corresponding to the commands, a signal transmission assembly (30) to transmit the tones from the electronics assembly (20) to an electronic control box (40) located elsewhere in the vehicle, and the electronic control box (40) to decode the transmitted tone. The use of discrete frequencies avoids operational problems associated with decreases in the overall system noise margin due to large voltage drops across the sliding contact (32). Furthermore, the use of off-the-shelf tone generation and decoding components allows for an (overall reduction in system cost and increase in system reliability.
