    摘要: A method and system for detecting intrusion on a CAN bus or vehicle network and neutralizing unauthorized intrusions. The system monitors the bit timing characteristics of CAN bus messages, message establishes trusted bit timing characteristics, and identifies unauthorized CAN bus messages. The device neutralizes unauthorized messages on the CAN bus by injecting data on the CAN bus at the appropriate time, preventing the unauthorized messages from being received, and presents alerts upon detection of the one or more of intrusions. It can be used as a standalone or hard-wired system, and may be accessible to the ODB-II port, relay or fuse port on a vehicle and may put other electronic control units on the vehicle into a safe operating mode upon receipt of the intrusion, neutralize all CAN message identifiers or set the intrusion detection flag to TRUE for all CAN message identifiers, sent by the same electronic control unit node.

    摘要: A vehicle authorization system with a transmitter/receiver capable of activating vehicle functions operably connected to the vehicle, a wireless transmitter/receiver for an authorized vehicle operator that receives communications from the vehicle transmitter/receiver, a sensor in the vehicle security transmitter/receiver that detects at least one vehicle access parameter via an electronic signal, wherein the vehicle transmitter/receiver communicates with the wireless transmitter/receiver responsive to the sensor detecting a second signal associated with the access parameter to affirm a verification signal from the wireless transmitter/receiver that upon verification permits vehicle access by the operator or upon improper or no response activates a vehicle function to prevent access or vehicle operation. The invention consists of a vehicle security device that can both monitor and control vehicle systems, and a user's smart device. The invention is combined with the existing vehicle keys and fobs to provide a two-step authentication.

    摘要: A replacement smart relay having a relay, controlled by a microcontroller operably connected through a power line communication line that receives instructions from a relay controller, the relay has a simulated resistor representative of a reference resistance, the instructions pass through commands that are sent to the relay control terminals to the relay switched terminals to allow the relay to function the same as the relay it is replacing in the existing application, the instructions from the relay controller are capable of opening or closing the relay switched terminals to override a command on the relay control terminals from the existing application based on a set of vehicle conditions communicated to the relay controller, and instructions from the relay controller allow the smart relay to act deterministically when the smart relay is not actively communicating with the relay controller. A feedback circuit may be used to enhance functionality.

    摘要: This invention provides a computer implemented method which allows the driver to request engine shut down and engine and restarts the engine of a motor vehicle by changing driver brake pedal force, that is, the force which the driver applies to the brake pedal, after the vehicle has stopped. After the vehicle has stopped, changes in the driver brake pedal force are compared to threshold values to determine if the driver is requesting an engine stop or an engine start.
