摘要:
A method is provided for controlling a powertrain of a vehicle comprising wheels, and an accelerator pedal actuated by a driver. The method comprises controlling wheel slip to a first amount during a first road condition, the first amount independent of a driver requested output; and controlling the wheel slip to a second amount during a second road condition, the second amount based on the driver requested output, the second road condition having higher friction than the first road condition.

A method for controlling a powertrain of a vehicle is provided for traction control. The method comprises controlling wheel slip to a first amount, the first amount independent of a driver requested output; and controlling the wheel slip to a second amount when a vehicle speed is less than a threshold for a first duration, the second amount based on the driver requested output.
摘要:
A method for controlling a powertrain of a vehicle with wheels during a traction control event is provided. The method comprises adjusting wheel torque in response to an amplitude of a band-pass filtered driven wheel speed and a direction of acceleration of driven wheels.

The method comprises controlling wheel slip to a first amount, the first amount independent of a driver requested output; and controlling the wheel slip to a second amount when a vehicle speed is less than a threshold for a first duration, the second amount based on the driver requested output. In this way, the driver is allowed to modify the wheel slip in a controlled way during specific traction control conditions.

A method for operating an engine having a variable cam timing control system, for controlling a camshaft angle in such engine. The method includes deactivating the variable cam timing system and setting the camshaft angle to a predetermined angle for a predetermined duration after failure in a sensor used to control the variable cam timing system and then reactivating the variable cam timing system after such predetermined time. The deactivating continues during the predetermined duration in the presence of a subsequent failure of the sensor during the predetermined duration. The reactivating comprises driving the cam angle to a camshaft angle established by the variable cam timing system in a predetermined manner. The reactivating occurs over a predetermined reactivation time.
摘要:
A method for adaptively learning is described that effectively and efficiently uses large amounts of data. Specifically, in one example, a scheme is described for determining whether to use data to adaptively learn parameters, or whether to discard the data. In this way, convergent data learning is possible.
