Abstract: The present disclosure is directed to driver assistance systems, such as blind sport detection systems, that integrate driver facing imaging devices. In one form, a system includes an imaging device configured to capture images of a face of a driver; at least one sensor positioned on the vehicle and configured to detect a distance from the vehicle to an object; and at least one processor configured to analyze the images and determine that the driver is in a drowsy state; determine, based on information received from the at least one sensor, that a distance between the vehicle and the object is decreasing or that the distance between the vehicle and the object is less than a threshold; and in response to the determinations, provide an alert to the driver of a potential side collision.

Abstract: A system and method system for determining when an object detected by a collision avoidance sensor on one member of an articulated vehicle comprises another member of the vehicle are provided. The system includes a collision avoidance sensor disposed on a first member of the vehicle and configured to detect an object within a field of view of the sensor on a side of the first member of the vehicle. The system further includes a controller configured to determine an articulation angle between the first member of the vehicle and a second member of the vehicle and to determine in response to the articulation angle, whether the second member of the vehicle is the object within the field of view of the collision avoidance sensor on the first member of the vehicle.

Abstract: A system and method system for determining the positions of one or more collision avoidance sensors on a vehicle is provided. The system includes one or more sensors disposed on the vehicle and configured to generate electromagnetic waves within corresponding fields of view on a side of the vehicle and to receive reflections of the waves from objects passing through the field of view of each sensor. A controller receives signals generated by the sensors responsive to the reflections and determines, responsive to the signals, relative speeds and relative directions of movement of the objects relative to the vehicle. The controller further determines the position of the sensors on the vehicle responsive to the relative speeds and relative directions of movement. In particular, the controller determines the location of sensors relative to the vehicle centerline and the relative positions and distances between sensors in the direction of vehicle travel.

Abstract: When mitigating collisions between a host vehicle and a forward vehicle, the forward vehicle is monitored and real-time data regarding distance and relative acceleration between the host and forward vehicles is used to continuously calculate a collision probability. The collision probability is used to calculate a deceleration request value sufficient to slow or stop the host vehicle within the following distance to the forward vehicle. The deceleration request value is transmitted to an antilock braking system (ABS) controller that caches the most-recently received value for execution upon receipt of an execution command. When the collision probability exceeds a first threshold, the ABS is instructed to arm the braking system. Upon detection of a brake pedal engagement, the ABS executes the brake request with the currently-cached value.

Abstract: A digital multimeter adapter for a portable electronic device includes a hardware interface connector and a computer program memory. The memory stores computer program instructions that direct the electronic device to collect data representative of a signal from an external source, analyzing the data to identify a characteristic such as voltage, current, or resistance, and displaying the data in digital format. The user may select one or more of the scales of the display. The adapter also may include a model value database, a collected value database, an application-specific database, and/or a language database.

Abstract: A signal processing apparatus for detecting and displaying the properties of diesel fuel powered compression-ignition engines senses strain pulses in the fuel injection rail structure to perform a variety of testing functions. Among other capabilities, the apparatus permits the user to establish stroboscope timing, to measure engine RPM, to view the relationship between crankshaft position and injection time, and to examine the time-dependent properties of strain pulses on individual fuel injectors in order to evaluate the condition of the diesel engine.

Abstract: A vehicle analysis system includes a system analyzer, such as an engine analyzer, having probes that gather data from vehicle parameters such as engine components. The data is converted into digital signals, which are processed into display data and stored in a computer memory. A controller converts the display data into packets that may be transmitted across a communications network to a remote computer using transmission control protocol/Internet protocol.

Abstract: An engine analyzer senses and displays secondary ignition signals from a DIS engine using a two sets of test leads. The engine analyzer receives the secondary signals from both sets of leads and produces positive and negative peak values for each set of leads during each cylinder firing. Based upon the positive and negative peak values for both sets of leads, during each of the cylinder firings, the engine analyzer selects which lead set and which polarity will be used to supply the secondary voltage signal for each cylinder to be digitized and displayed.

Abstract: A vehicle diagnostic system has a processor unit designed to be coupled to the vehicle to receive signals from the vehicle. The processing unit is connected to a long-term memory that stores instructions to be executed by the processing unit. The long-term memory also stores display values capable of being translated into a perceivable output. The instructions stored in the long-term memory include coding objects of a first type that are capable of calling other coding objects of the first type during execution. A random access memory is also coupled to the processing unit to receive a copy of some instructions stored in the long-term memory. At least one coding object of the first type copied into the random access memory includes a reference to a display value stored in long-term memory. The display value is copied into a display portion of the random access memory during execution and is retrieved by a user interface coupled to the random access memory.

Abstract: A data driven, multi-dimensional diagnostic method that combines vehicle system test data, vehicle attributes, symptoms, and extrinsic data to produce vehicle system diagnostics. Data are combined according to predetermined equations to yield intermediate diagnostic results. Intermediate diagnostic results are combined recursively according to fixed expressions to produce final diagnostic results relating to the state of the vehicle system under diagnosis. Fixed expressions may be algebraic, Boolean, fuzzy logic, statistical, or relate to an expert system.
