Assignee:

General Motors Corporation - Detroit MI

International Classification:

F02D 902

US Classification:

123396, 123399

Abstract:

A method of controlling a motor vehicle engine having an electronic throttle including positioning the electronic throttle in response to a requested throttle area, determining a fault in the vehicle engine, limiting the throttle area after a fault has been determined to control vehicle speed, limiting acceleration of the vehicle after the fault has been determined, and determining if the engine may be operated at full throttle after the fault has been determined to allow the vehicle to operate in a high power demand application.

International Classification:

F02D 100

US Classification:

123399, 701110, 123396

Abstract:

Methods and apparatus are provided for adjusting a throttle of a vehicle engine. The apparatus comprises an input sensor configured to provide an input signal having a value that approximately corresponds to an operating level of the vehicle engine requested by an operator and a memory configured to store a maximum input value for the input sensor. The maximum input value provides the value of the input signal that approximately corresponds to a maximum operating level of the vehicle engine. The apparatus is further configured to receive the input signal and access the memory to retrieve the maximum input value and further configured to update the maximum input value with the value of the input signal if the value of the input signal is greater than the maximum input value.

US Classification:

701 54, 701 29, 701 36

Abstract:

An engine management system for a vehicle includes engine and transmission control modules that are connected to a serial vehicle data bus. A dedicated serial data bus is connected to the transmission control module and the engine control module. The engine and the transmission control modules perform processor validity and integrity checks over the dedicated data bus. In an alternate powertrain management system, engine and transmission control modules are connected to a serial vehicle data bus.
