  • Patent number: 11010996
    Abstract: A system includes a transmitter, a receiver and a control module. The transmitter transmits a RF signal from one of a vehicle and a portable access device to the other one of the vehicle and the portable access device. The receiver receives a response signal from one of the vehicle and the portable access device in response to the RF signal. The control module: converts the response signal to in-phase and quadrature-phase signals; based on the RF, in-phase signal and quadrature-phase signals; detects a range extension type relay attack performed by an attacking device to obtain at least one of access to or operational control of the vehicle; where the RF signal is relayed via the attacking device from the vehicle to the portable access device or the response signal is relayed via the attacking device from the portable access device to the vehicle; and performs a countermeasure.

  • Patent number: 8489354
    Abstract: A method for verifying the speed of a vehicle having at least a front axle and a rear axle, using sensors separated by a distance. The presence of the vehicle is sensed and an image of the vehicle is recorded to enable the vehicle to be identified. The sensors are triggered to emit signals which are received by the system to enable the speed of the vehicle to be determined. The signals are also used to determine a wheel base measurement for the vehicle. The determined wheel base measurement is compared to an actual wheel base measurement of the vehicle being sensed and any discrepancy between them is taken to be indicative of potential errors in the speed of the vehicle determined by the method. In one embodiment, the a database is provided, the database containing data relating to various vehicle types associated with vehicle specifications including a validated wheel base measurement for each vehicle type.

  • Publication number: 20120265366
    Abstract: A dynamic method to accurately determine the mass of a vehicle which deforms on acceleration and is subject to low frequency noise is disclosed. Only the greater than zero hertz frequencies of the signals are processed. Both signals are squelched during periods of high jerk to reduce the error between true mass and apparent mass. For a single body or combination vehicle such as a semi-rig with a propulsive body of known mass a reference for matched or Wiener filtering is constructed from the noisy signals to filter low frequency noise. A towing vehicle with a fifth wheel mounted on a dedicated load sensing apparatus can, therefore, determine the weight of any semi-trailer towed on any terrain of any inclination and any changing inclination with the greatest precision in the shortest possible time.

  • Patent number: 8195422
    Abstract: First and second devices having clocks which may have different clock rates. Obtaining a measure of the distance of propagation of a signal passing between the devices involves transmitting a first signal 12 from the first device to the second device. After a turnaround time TAT, a second signal 14 is transmitted from the second device to the first device. Any error in the clocks may lead to an error in the measurement of the turnaround time TAT. One device contains circuitry to calculate the ratio of the clock rates of the first and second devices, either by adjusting frequency divider ratios until there is LO frequency match, or by determining the offset frequency of an envelope of a mixed signal. The ratio of the clock rates is used to compensate the turnaround time TAT, to mitigate error. The accurate distance measurement can be used to determine if a relay attack has taken place in a vehicle security system.
