Abstract: A control system to generate a yaw torque of an all-wheel drive vehicle comprises a brake control module 18. The brake control module 18 determines the desired powertrain torque 44 for the vehicle 10 based upon a plurality of factors including available torque from the powertrain. The brake control module 18 determines a first torque 44 and a second torque 26, wherein the first torque 44 and the second torque 26 are combined to provide the total desired yaw torque 49 of the vehicle 10. The first torque 44 is generated between wheels of the vehicle 10 by applying torque 44 from the powertrain 14 to different wheels 21 of the vehicle 10 and the second torque 26 is generated by applying different braking torque from a braking system 16 of the vehicle 10.

Abstract: A method of providing parked vehicle protection comprises determining if a vehicle ignition is in an off position and monitoring an exterior area proximate to a vehicle with a plurality of sensors when the vehicle ignition is off to detect an object proximate to the vehicle. The ECU determines whether the object is within a first object range and provides a first external warning when the object is within the first object range and determines whether the object is within a second object range and provides a second external warning when the object is within the second object range.

Abstract: A vehicle stability control system operates by detecting a wheel speed potentially indicative of the presence of a mini-spare wheel at a wheel location of a vehicle with a wheel speed sensor and determines that a mini-spare tire is present responsive to the wheel speed remaining within a predefined band for predefined time. A threshold value that triggers action by a vehicle stability control system is adjusted to provide the mini-spare wheel with a value different than a wheel speed threshold value indicative of wheel slipping for a standard wheel.

Abstract: A receiver in an audio coding system receives a signal conveying frequency subband signals representing an audio signal. The subband signals are examined to assess one or more characteristics of the audio signal including temporal shape. Spectral components are synthesized having the one or more assessed characteristics, integrated with the subband signals and passed through a synthesis filterbank to generate an output signal.

Abstract: In an optimized hydraulic brake system, a pedal travel sensor is used to improve pedal feel. In order to improve pedal feel, a low pressure is detected in the brake booster and the brake hydraulic system is used to increase wheel pressure. This prevents the operator from having to exert an increasing large force on the brake pedal during a deceleration situation.

Abstract: Blocks of audio information are arranged in groups that share encoding control parameters to reduce the amount of side information needed to convey the control parameters in an encoded signal. The configuration of groups that reduces the distortion of the encoded audio information may be determined by any of several techniques that search for an optimal or near optimal solution. The techniques include an exhaustive search, a fast optimal search and a greed merge, which allow the search technique to tradeoff the reduction in distortion against the bit rate of the encoded signal and/or the computational complexity of the search technique.

Abstract: Audio coding processes like quantization can cause spectral components of an encoded audio signal to be set to zero, creating spectral holes in the signal. These spectral holes can degrade the perceived quality of audio signals that are reproduced by audio coding systems. An improved decoder avoids or reduces the degradation by filling the spectral holes with synthesized spectral components. An improved encoder may also be used to realize further improvements in the decoder.

Abstract: An audio crosstalk-cancelling network that may be implemented in software, such that when run in real time on a personal computer, the canceller has very low mips requirements and uses a small fraction of available CPU cycles. The network is particularly useful for rendering surround sound images outside the space between left and right computer multimedia loudspeakers when the audio from such sources is reproduced. The network includes two signal feedback paths, each feedback path having a time delay and frequency dependent characteristic. The frequency dependent characteristic represents the smoothed difference in the attenuation in the acoustic path between a transducer and the listener's ear farthest from said transducer and the attenuation in the acoustic path between the same transducer and the listener's ear closest to said same transducer. The smoothed difference in the attenuation is implemented by one or more simple digital filters requiring low processing power.

Abstract: A split-band coding system combines multiple channels of input signals into various forms of composite signals and generates spatial-characteristic signals representing soundfield spatial characteristics in a plurality of frequency subbands. The spatial-characteristics signals may be generated in either or both of two forms. In a first form, the signal represents measures of signal levels for subband signals from the input channels. In a second form, the signal represents one or more apparent directions for the soundfield. The type of the spatial-characteristics signal may be adapted dynamically in response to a variety of criteria including input signal characteristics. Temporal smoothing and spectral smoothing of the spatial-characteristics signals may be applied in an encoder. Temporal smoothing and spectral smoothing may be applied to gain factors derived from the spatial-characteristics signals in a decoder.
