  • Patent number: 11807276
    Abstract: A method includes determining a target specification map that is associated with a task and that indicates, for each respective region of a plurality of regions around a vehicle equipped with a sensor, a target value of a parameter of the sensor. The method also includes determining a capability specification map that indicates, for each respective region, an attained value of the parameter that the sensor is configured to provide. The method additionally includes comparing the capability specification map to the target specification map to determine, for each respective region, a disparity between the target value and the attained value. The method further includes, based on the comparing, identifying one or more of: a first subset of the plurality of regions where the target value exceeds the attained value or a second subset of the plurality of regions where the attained value meets or exceeds the target value.

  • Patent number: 8050857
    Abstract: A control system (18) and method for an automotive vehicle (10) includes a roll rate sensor (34) for generating a roll rate signal, a lateral acceleration sensor (32) for generating a lateral acceleration signal, a longitudinal acceleration sensor (36) for generating a longitudinal acceleration signal, and a yaw rate sensor (28) for generating a yaw rate signal. A safety device or system (44) and the sensors are coupled to a controller. The controller (26) determines an added mass and the height of the added mass on the vehicle, or a roll gradient, a roll acceleration coefficient, and/or a roll rate parameter that take into account the added mass and height from the roll rate, the lateral acceleration, the longitudinal acceleration, and the yaw rate of the vehicle, and controls the safety system in response thereto.

  • Publication number: 20110260988
    Abstract: A haptic device capable of providing a force on a finger or object in contact with a substrate surface includes a substrate having a touch surface, includes a substrate having a touch surface, at least one first actuator for subjecting the substrate to out-of-plane ultrasonic oscillations controlled to provide relatively low and high friction states of the touch surface and at least one second actuator for subjecting the substrate to lateral oscillations while the substrate is alternated between the low and high friction states in a manner to generate a force felt by a user's finger on the touch surface. A control device provides signals to the at least one first actuator to establish relatively low and high friction states of the touch surface. An electrical damping circuit between the control device and the at least one first actuator is implemented for reducing the transition time between the low and high friction states.

  • Patent number: 7729829
    Abstract: A vehicle suspension system (19) includes a suspension (47). A lateral acceleration sensor (32) generates a lateral acceleration signal. A roll rate sensor (34) generates a roll rate signal. A controller (26) detects an irregularity in the suspension in response to the lateral acceleration signal and the roll rate signal. A method of detecting suspension irregularities in a vehicle (10) includes the generating of a lateral acceleration signal and a roll rate signal. Roll angle is determined in response to the lateral acceleration signal and roll rate signal. A roll gradient, a roll acceleration coefficient, and a roll damping parameter are determined in response to at least the roll angle. The roll gradient, the roll acceleration coefficient, and the roll damping parameter are compared to associated nominal values. A suspension irregularity is indicated in response to the comparison.
