摘要： A control system for an automotive vehicle having a vehicle body includes a sensor cluster having a housing oriented within the vehicle body. A roll rate sensor is positioned within the housing and generates a roll rate sensor signal corresponding to a roll angular motion of the sensor housing. A controller receives the roll rate sensor signal and generates a reference roll angle. The controller also compares the reference roll angle to the roll rate sensor signal and generates a roll rate sensor fault signal in response a fault determined in said roll rate sensor.

摘要： A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated friction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided.

摘要： A method and apparatus for determining lateral velocity of a vehicle (10) uses a controller (16) having a lateral velocity estimator (18) therein. A vehicle speed determination circuit (20) is used to determine the vehicle speed which is coupled to the controller (16). A yaw rate sensor (26) is used to generate a yaw rate signal, a lateral acceleration signal (28) is used to generate a lateral acceleration signal, and a roll angle sensor (30) is used to generate a roll angle signal that are each coupled to controller (16). The controller (16) measures an unbiased lateral velocity derivative and determines a fictitious lateral velocity estimation using the unbiased lateral velocity derivative. Using the fictitious error to drive a model based adaptive observer, an accurate lateral velocity determination may he made in spite of model uncertainties and measurement noise.

摘要： An apparatus and method for measuring dynamic movement of a vehicle (10) by employing multiple GPS satellites and determining velocity based change in the carrier frequency of multiple satellite signals. The apparatus includes at least two GPS receiving antennas (12a and 12b) installed on a vehicle (10) at known locations and a controller (20) for processing received GPS signals (16a-16c) and monitoring a carrier frequency associated with the GPS signals. The controller (20) determines a change in the carrier frequency of the GPS signals due to Doppler effect. The controller (20) further determines a first inertial velocity vector of each of the receiving antennas (12a and 12b) based on the change in carrier frequency, and determines angular rate of the vehicle based on the inertial velocity vectors. The controller (20) further determines vehicle longitudinal and lateral velocity and acceleration as a function of the inertial velocity vectors.
