Abstract: An electronic control unit for adaptive cruise control of a vehicle, comprises an interface operable to receive data from a plurality of sensors and a training module operable to analyze the data and determine a first set of parameters for a first performance mode of the adaptive cruise control system. The first set of parameters is learned based upon the received data. A reading module is operable to read a recorded second set of parameters for a second performance mode, wherein the second set of parameters are read from the received data. A comparison module is operable to select one of the first performance mode and the second performance mode and a controller is operable to receive the set of parameters associated with the selected performance mode, wherein the controller determines desired vehicle actions based on the received set of parameters and send instructions to implement the desired vehicle actions.

Abstract: A method of estimating values beyond sensor limits accurately and simply includes the initial step of determining an actual slope utilizing measured data. An estimated slope is then determined as a percentage of the actual slope to provide an estimation of data values outside of the sensor limits until measured values return to within sensor limits. The estimation method according to this invention increases sensor range without sacrificing resolution with a desired accuracy.

Abstract: A strategy for determining the type of impact condition experienced by a vehicle (24) and for deciding whether to deploy a supplemental restraint device such as an airbag (22) includes using a difference between a front sensor (32) velocity and a tunnel sensor (34) velocity. Determining whether the difference between the front sensor velocity and the tunnel sensor velocity exceeds a difference threshold provides information regarding an impact condition that allows a controller to operate at a lower bandwidth and in a more reliable fashion. By combining the determination whether the difference threshold has been exceeded with at least one other parameter, at least three discreet types of impact conditions can be discriminated and a decision can be made whether to deploy a supplemental restraint device.

Abstract: The method of controlling fuel supply comprises the steps of detecting a value related to velocity of a vehicle along a first path and detecting a value related to velocity along a second path transverse to the first path. The detected values are then combined and compared to a threshold. The fuel supply is then controlled based on the comparison of the combined values with the threshold. Using this method, a fuel safety system comprises a fuel system of a vehicle, a fuel cutoff switch controlling the transmission of fuel through the fuel system, a sensor detecting a value related to velocity of the vehicle along the first path, and a sensor detecting a value related to velocity of the vehicle along a second path transverse to the first path. A control unit combines the detected values and activates the fuel cutoff switch based on the comparison.
