Abstract: Embodiments of the invention relate to a method of implementing role-driven notification. The method includes storing, by a cloud infrastructure system including computing devices, notification templates. Each of the notification templates are associated with a role. The method further includes determining that a user is associated with a first role and a second role, determining that the first role is associated with a first notification template and the second role is associated with a second notification template. Further, the method includes combining the first template and the second template to generate a third template, based on the third template, generating a notification. The method then, sends the notification to the user.

Abstract: A method for controlling an engine of a vehicle in response to an operator input, comprising, during a first non-cruise control condition and at first distance to a forward vehicle, adjusting engine output in response to said operator input with a first relationship; and during a second non-cruise control condition and at a second, greater, distance to a forward vehicle, adjusting engine output in response to said operator input with a second relationship different from said first.

Abstract: A vehicle control method for transitioning through transmission lash regions is described using a variety of information, such as, for example, gear ratio, clutch slippage, etc. Further, different adjustment of spark and throttle angle is used to provide a rapid torque response while still reducing effects of the lash. Finally, transitions taking into account both slipping and non-slipping transmissions are described.

Abstract: In one example, a system for an engine having an intake system and an exhaust system is described. The system comprises: an airflow sensor coupled to the intake system; an air pump having at least an inlet side and an outlet side, said inlet side having a first coupling to the intake system downstream of said airflow sensor, said outlet side having a second coupling to the exhaust system; and a controller coupled to the engine, said controller, during operation, identifying whether degradation has occurred to at least one of said first and second couplings, and providing an indication of said identified degradation. Various other examples are also disclosed.

Abstract: A method of controlling fuel injection in an engine of a vehicle having an all wheel drive or 4×4 system comprises restricting deactivation of the fuel injection during some deceleration conditions when the vehicle is in an all wheel drive, or 4×4, low gear. According to another aspect, a method comprises restricting deactivation of fuel injection during deceleration operations under all wheel drive, or 4×4 low gear operation; and disabling the fuel injection during at least some deceleration operation under other conditions. Disabling deactivation in an all wheel drive or 4×4 low gear allows a more controlled drivability at a time when any torque disturbance may be magnified and more easily felt by the vehicle driver.

Abstract: A method of controlling fuel injection in an engine of a vehicle having an anti-lock braking system comprises under conditions of degraded operation of an anti-lock braking system, restricting deactivation of the fuel injection during deceleration vehicle operating conditions. According to another aspect, the method comprises under conditions where the anti-lock braking system is functioning, disabling fuel injection during at least some deceleration operations; and under conditions of degraded operation of the anti-lock braking system, restricting deactivation of the fuel injection during deceleration vehicle operating conditions. By considering the functioning of an ABS, it is possible to deactivate fuel injection during some deceleration operations during one condition to realize fuel economy gains and disable the deactivation of fuel injection at another condition to reduce engine stalls. Thus, the deceleration fuel shut off strategy may be used aggressively for improved fuel economy.

Abstract: A method for controlling an engine of a vehicle operated by a driver may comprise detecting actuation of a braking device of the vehicle by the driver; calculating a parameter indicative of an actual amount of braking effort by said driver based on vehicle conditions; and adjusting an engine operating parameter based on said parameter. The method can adjust a number of cylinders carrying out combustion, fuel cut operation, a level of powertrain output torque (positive, and/or negative), and/or other engine parameters.
