  • Publication number: 20170082053
    Abstract: A method and apparatus for identifying a faulty fuel injector is disclosed. The fuel injectors are commanded in sequence to inject a fuel quantity. A plurality of values of a crankshaft rotational speed is measured during the combustion of the injected the quantities. The measured values are processed to calculate a respective unbalancing value representative of the fuel quantity injected by the fuel injector. An average value of the calculated unbalancing values is calculated and subtracted from each of the unbalancing values to obtain a respective adjusted unbalancing value. The standard deviation of the adjusted unbalancing values is calculated and multiplied with each of the adjusted unbalancing values to obtain a respective corrected unbalancing value. The corrected unbalancing values are compared with a predetermined threshold value thereof, and a faulty fuel injector is identified if the corresponding corrected unbalancing value exceeds the predetermined threshold value.

  • Patent number: 9599706
    Abstract: A method and system are disclosed for tracking objects which are crossing behind a host vehicle. Target data from a vision system and two radar sensors are provided to an object detection fusion system. Salient points on the target object are identified and tracked using the vision system data. The salient vision points are associated with corresponding radar points, where the radar points provide Doppler radial velocity data. A fusion calculation is performed on the salient vision points and the radar points, yielding an accurate estimate of the velocity of the target object, including its lateral component which is difficult to obtain using radar points only or traditional vision system methods. The position and velocity of the target object are used to trigger warnings or automatic braking in a Rear Cross Traffic Avoidance (RCTA) system.

    Abstract: A system and method for determining when to reset a controller in response to a bus off state. The method includes determining that the controller has entered a first bus off state and immediately resetting the controller. The method further includes setting a reset timer in response to the controller being reset, determining whether the controller has entered a subsequent bus off state, and determining whether a reset time. The method immediately resets the controller in response to the subsequent bus off state if the reset time is greater than the first predetermined time interval, and resets the controller in response to the subsequent bus off state after a second predetermined time interval has elapsed if the reset time is less than the first predetermined time interval.

  • Publication number: 20170072941
    Abstract: A method of determining a regeneration schedule for a vehicle having an internal combustion engine, an electric machine, and a plurality of yaw rate actuators. The method includes determining an allowable yaw rate change based on dynamic conditions of the hybrid vehicle, a combined mitigation potential of the yaw rate actuators, and a regeneration torque command that causes an actual yaw rate change. Determining the regeneration torque command includes comparing the allowable yaw rate change to the combined mitigation potential. If the combined mitigation potential is less than the allowable yaw rate change, the regeneration torque command causes or limits the actual yaw rate change to be lower than the allowable yaw rate change. If the combined mitigation potential is greater than the allowable yaw rate change, the regeneration torque command causes or limits the actual yaw rate change to be substantially equal to the allowable yaw rate change.

    Abstract: A releasable joint configured to attach a cradle to an underbody of a vehicle subjectable to an external force includes a fastener, an attachment portion of the cradle, and a partial sleeve. The fastener attaches the cradle to the underbody. The attachment portion of the cradle encircles the fastener and includes a breakaway portion that fractures when the external force exceeds a threshold force. The partial sleeve is attached to and disposed within the attachment portion of the cradle and partially encircles the fastener so as to form an opening that provides a horizontal pathway for the fastener to move through to exit the cradle when the breakaway portion fractures. The cradle may separate from the underbody at the releasable joint with no vertical motion of the cradle relative to the underbody when the external force exceeds the threshold force.

  • Publication number: 20170072940
    Abstract: A method of controlling a vehicle includes calculating a desired deceleration limited regeneration torque request based on a requested deceleration input from a driver. If current dynamic operating conditions of the vehicle are in a performance region that permits an increase to the regeneration torque request, the desired deceleration limited regeneration torque request is increased based on a regeneration torque overhead, to define a modified axle regeneration torque request. Modified torque values are output based on the modified axle regeneration torque request. If the torque control values will cause an estimated yaw rate that is less than a target yaw rate, then the modified torque values are applied. Otherwise, the modified torque values are re-defined until the estimated yaw rate is not greater than the target yaw rate, and the re-defined values of the modified torque values are applied.

  • Publication number: 20170072780
    Abstract: A method of controlling a vehicle having a first axle driven by an internal combustion engine, and a second axle independently driven by an electric device includes determining if the accelerator pedal is disposed in a depressed position or in a non-depressed position, and determining if a brake pedal is disposed in a depressed position or in a non-depressed position. An axle control strategy for controlling energy regeneration of an energy storage device is selected based on the position of the accelerator pedal being in either the depressed position or the non-depressed position, and the position of the brake pedal being in either the depressed position or the non-depressed position. A control signal is communicated to at least one of the first axle or the second axle to implement the selected axle control strategy.
