  • Publication number: 20200198416
    Abstract: A wireless tire pressure monitor system configured for transmitting tire pressure information of a tire of a vehicle is described. The wireless tire pressure monitor system comprises a vehicle-based receiver, at least one tire pressure sensor configured to be mounted inside the tire and configured to measure the air pressure within the tire, and a transmitter electronically connected to the tire pressure sensor and configured to transmit a signal comprising the tire pressure information to the vehicle-based receiver. The wireless tire pressure monitor system is configured to transmit the signal in a first transmission mode from the transmitter to the vehicle-based receiver when the tire is rotating, and transmit the signal in a second transmission mode from the transmitter to the vehicle-based receiver when the tire is stationary. Moreover a method of transmitting tire pressure information employing a wireless tire pressure monitor system is described.

  • Publication number: 20200180587
    Abstract: A brake pad wear measuring system for measuring brake pad wear for a vehicle disc brake system includes a first coil having a first coil face and is excitable to create a first magnetic field. A first target is spaced a fixed distance from the first coil face. The first coil and the first target are configured for movement relative to each other in response to application of the disc brake system so that the first target covers a portion of the first coil that varies with the amount of brake pad wear and varies the inductance of the first coil. The inductance of the first coil is indicative of the amount of brake pad wear. The brake pad wear measuring system also includes a second coil having a second coil face and is excitable to create a second magnetic field.

  • Patent number: 10604114
    Abstract: A method for controlling access to a vehicle includes storing at a vehicle-based system a GPS location of the vehicle associated with the location at which the vehicle is parked. The vehicle-based system communicates with a mobile device to obtain a GPS location of the mobile device. The vehicle-based system blocks entry to the vehicle if the GPS location of the mobile device is outside a predetermined distance from the stored GPS location of the vehicle.

  • Patent number: 10543808
    Abstract: Method for preventing security breaches via the two-thief method of attack of passive remote keyless entry systems for vehicles. The method involves the transmission of a signal between a fob and the vehicle, where the level of the signal changes in a particular pattern. At the receiving side, anomalies in the pattern of the received signal (e.g., levels, timing) are detected and used to detect attempts to mimic the signal.

  • Patent number: 10486648
    Abstract: A passive keyless entry system for an electronic lock, comprises a lock installation including a lock controller, and an RF transmitter and receiver, and a fob with a controller, and an RF transmitter and receiver. The fob generates messages to unlock the lock in an unlock event. The controllers share a secret specifying parameters for a sequence of messages to be exchanged bidirectionally between the installation and the fob, the parameters changing between each unlock event and an immediately subsequent unlock event. For each unlock event one of the controllers generates and sends a first message of the message sequence, in accordance with the specified parameters. The other controller causes transmission of a second message of the sequence in accordance with the specified parameters, in response to receiving the first message. At least one message of the sequence comprises a plurality of frames, each frame including a particular sequence of bits, adjacent frames being separated by an inter-frame interval.

  • Publication number: 20190264764
    Abstract: A brake pad wear measuring system for measuring brake pad wear for a vehicle disc brake system includes an inductive sensor operable to create a magnetic field and a target. At least one of the sensor and the target are mounted for movement along a braking axis with a component of the disc brake system. The positions of the sensor and target relative to each other changes in response to application of the disc brake system. The distance that the sensor and target move relative to each other in response to application of the disc brake system increases an amount that is equal to the total wear of the inner and outer brake pads. The sensor is responsive to the change in inductance caused by movement of the target in the magnetic field to provide a signal indicative of brake pad wear.

  • Publication number: 20190242450
    Abstract: A brake pad wear sensing system for measuring brake pad wear for a vehicle disc brake system includes a brake pad wear sensor including a near field communication (“NFC”) circuit for transmitting an NFC signal and a tank circuit including a resonating component and a charge storage component. The tank circuit powers the brake pad wear sensor including the NFC circuit. The tank circuit is configured to be inductively charged in response to interrogation by a NFC device positioned within a predetermined proximity of the brake pad wear sensor. The NFC circuit is configured to respond to the interrogation by the NFC device to transmit the NFC signal. The resonating component or the charge storage component has a physical condition or effective component value that is configured to be degraded in response to brake pad wear. The degradation of the resonating component or the charge storage component reducing the signal strength with which the NFC signal is transmitted.

  • Patent number: 10363902
    Abstract: A method for defeating a two-thief attack on a passive RKE system by using frequency hopping. Radio frequency signals are transmitted between a fob and a vehicle. The transmitted signals hop between at least two radio frequency transmitting channels in a particular pseudo-random pattern known to the vehicle. At the vehicle, the transmitted signals are received in a process that is sequentially adjusted to take account of the known characteristics of each portion of the known pattern. Anomalies in the pattern of the received signals are detected and, if the anomalies exceed permissible limits, access to said vehicle is blocked.

  • Publication number: 20190226542
    Abstract: A brake pad wear measuring system for measuring brake pad wear for a vehicle disc brake system includes a first and second coil excitable to create a first and second magnetic field and first and second targets associated with the first and second coils. The coils and targets are configured for movement relative to each other along an axis in response to application of the disc brake system. The relative movement along the axis causes the targets to move within the magnetic fields and affect the inductance of the coils. The first coil and the first target are configured so that the inductance of the first coil is indicative of the amount of brake pad wear. The inductance of the second coil is indicative of component shifting transverse to the axis.
