Abstract: A vehicle network security arrangement for a vehicle, having a network vulnerable to attacks from at least one threat. One or more external devices, being a source of at least one threat, are connectable and communicate with a vehicle network. A cyber security device is connected to the network and receives data being sent to and data transmitted from the network. The cyber security device includes a memory and an anomaly detection system (ADS) that detects the at least one threat in the data being begin sent to the network and the data being sent from the network. A memory of the cyber security device keeps a data log that contains information concerning the at least one threat, which is accessible by a user accessing the memory of the cyber security device.

Abstract: An Intrusion Defense System for protecting the computer systems of a vehicle includes a vehicle having a computer with a direct wired or Radio frequency or other contact-less remote connection diagnosis connection port interface. A hardware device for protecting the computer from hazardous software code intrusions into the computer system. is used to protect the computer from unwanted hacks or intrusions into the system. The hardware device includes at least one or more of: a Diagnostic Port Gateway; a CAN Conditioner; and a CAN Data Security Diode and combinations of these.

Abstract: An improved method of controlling an electro-hydraulic control system by developing a motor control command in relation to the desired force to be exerted by an electric motor on a mechanical element whose displacement determines the hydraulic pressure. The control command is comprised of two magnitude signals. The first magnitude signal must be sufficient to exert enough force to overcome a static friction characteristic of the mechanical element, and the second magnitude signal is selected to achieve a desired average current or voltage over that control period. The time constant for the control command is less than the mechanical time constant of the system, but greater than the the electrical time constant of the system. The control command may be implemented by using either current or voltage control.

Abstract: In a vehicle anti-lock brake controller, a differential slip between the wheels on each side of an axle is sensed to detect a yaw condition and the wheel with the lower slip value is identified as the high coefficient wheel. In response to a detected yaw condition, the monitored value of slip of the high coefficient wheel is controlled about a target slip value that has an initial value less than the critical slip value at the beginning of antilock controlled braking to minimize longitudinal force imbalance and which is thereafter ramped to the critical slip value to maximize longitudinal braking forces.
