Appl. No.:

12/497201

Inventors:

Rogelio Rodriguez - Plainfield IL, US
Ly V. Tran - Carol Stream IL, US

Assignee:

International Engine Intellectual Property Company, LLC - Lisle IL

International Classification:

G06F 19/00

US Classification:

701 29, 30312203, 30312204, 30312205, 701 36, 701 70, 701 291, 701 297, 701 304, 701 309, 701 311, 701 318

Abstract:

A motor vehicle has wheels on which it travels, a powertrain delivering propulsion torque to at least some of the wheels propel the vehicle, and a service brake system having service brakes. When the service brakes are applied by a service brake actuator, braking torque is applied to at least some wheels. A first device provides data representing a velocity that correlates with velocity of the vehicle, and a second device associated with the actuator provides data that distinguishes between application and non-application of the service brakes by the actuator. A processor monitors data from the first and second devices and processes the monitored data to provide a data output when the first device has disclosed velocity change indicative of the service brakes having been applied without the second device having disclosed that the service brakes have been applied.

Assignee:

International Engine Intellectual Property Company, LLC - Warrenville IL

International Classification:

F02G 5/00
G06F 19/00

US Classification:

123549, 123556, 701113

Abstract:

A motor vehicle has an engine compartment () and a compression ignition engine () disposed within engine compartment (). Engine () has an air intake () through which combustion air enters the engine. A heater () heats combustion air passing through air intake (). A sensor () indicates temperature in air intake (). When temperature indicated by sensor () is greater than a reference temperature that demarcates a warm engine from a cold engine, a control () enables heater () to heat combustion air passing through air intake () upon engine starting and during a subsequent period of initial engine running whose duration is a function of temperature indicated by sensor () at engine starting.

Abstract:

According to at least one aspect of the present technology, a method is provided for compensating the output of a mass air flow sensor in response to humidity level. The method includes determining an actual mass air flow value (MAF_ACT) using the mass air flow sensor. The method also includes determining an actual humidity value (HUM_ACT) of the air flow that is measured by the mass air flow sensor. The method further includes determining if the actual humidity value (HUM_ACT) is outside of a preselected operating range. If the actual humidity value (HUM_ACT) is outside of the preselected operating range, the method determines a humidity-compensated mass air flow value (MAF_HUM) as a function of the actual mass air flow value (MAF_ACT) and the actual humidity value (HUM_ACT).
