The control unit accesses the CAN data bus of the drive train of the carrier vehicle to deliver the current speed, the current gear selected and the position of the brake pedal, which represent important input variables for the simulation. | 2010-05-27 |

The meter comprises: two sensor inputs, to receive a digital signal related to the speed of a said rotating element; an external input, to accept a command or value; an output, to display or transmit a measurement or calculation result; and a controller, to calculate the relative speed of the two rotating elements, compare the relative speed to a set-point, and output a result indicative of belt slip. | 2010-05-27 |
20100131233 | METHOD AND APPARATUS FOR DRIVER HANDS OFF DETECTION FOR VEHICLES WITH ACTIVE FRONT STEERING SYSTEM - A system and method for detecting the absence of contact between the hands of a driver of a vehicle and a steering wheel of the vehicle that have particular application in ensuring the proper functioning of various components of the driver assist steering systems and maintaining driver attentiveness. The method for detecting a no-contact condition between the hands of the driver of the vehicle and the steering wheel includes generating a model of the no-contact condition using a second-order transfer function. The method further includes obtaining a set of model-generated steering dynamics by estimating a plurality of parameters of the second-order transfer function and a set of measured steering dynamics using a plurality of sensors. The set of model-generated steering dynamics and the set of measured steering dynamics are then compared and the no-contact condition is detected based on this comparison. | 2010-05-27 |
20100131234 | SYSTEM AND METHOD FOR MEASURING AND MAPPING A SURFACE RELATIVE TO A REFERENCE - A system and method for measuring the displacement of a surface relative to a base reference, as well as for mapping the displacement of the surface relative to the base reference. A laser scanner generates point cloud data in respect of a measure of the spatial orientation of a distal surface relative to a reference point to define a three-dimensional image of the surface. Reference data is stored in respect of the spatial orientation of a base reference relative to the surface. processing means to process said point cloud data and said base reference data to determine the relative displacement of said surface with respect to said base reference. A system comprising: data processing means to obtain point cloud data defining a surface in a co-ordinate system coinciding with a base reference and to generate displacement data in respect of the displacement between each point of said point cloud and a related point of said base reference; comparison means to compare the displacement data against a prescribed threshold; and display means to graphically display the result of the comparison. | 2010-05-27 |
