International Classification:

G06G007/70

US Classification:

123/399000, 701/110000, 123/396000

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.

International Classification:

G06F007/00

US Classification:

701070000

Abstract:

A powertrain braking system for a vehicle includes an powerplant that can be regulated to provide a desired powerplant torque and a transmission that transfers the desired powerplant torque at one of a plurality of gear ratios to provide a desired axle torque. A control module calculates an axle torque command based on a powertrain braking request and determines a shift command based on the powertrain braking request. The control module controls the powerplant based on the axle torque command and the transmission based on the shift command to achieve a desired vehicle deceleration rate that corresponds with the powertrain braking request.

International Classification:

G06F 17/00

US Classification:

701 54

Abstract:

A method of regulating a torque output of a vehicle powertrain includes generating a plurality of torque requests and associating each of the plurality of torque requests with one of a plurality of arbitration domains to form torque request sets associated with each of the plurality of arbitration domains. A first torque request set is arbitrated within a first of the plurality of arbitration domains to provide a first torque request. The first torque request is introduced into a second torque request set associated with a second of the plurality of arbitration domains. The second torque request set is arbitrated within the second arbitration domain to provide a second torque request. A torque source is regulated based on the second torque request.

International Classification:

B60W 10/04

US Classification:

701 84

Abstract:

A method and system for regulating a drive torque provided to a driveline of a vehicle includes monitoring an accelerator pedal position and a brake pedal position. An adjusted accelerator pedal position is determined based on the accelerator pedal position and the brake pedal position and a drive torque request is determined based on the adjusted accelerator pedal position. Drive torque is generated based on the drive torque request.

International Classification:

F02D 45/00

US Classification:

701102

Abstract:

An engine control system comprises a torque request module, an immediate torque control module, an actuation module, and an expected torque control module. The torque request module generates an expected torque request and an immediate torque request. The immediate torque control module controls a spark advance of an engine based on the immediate torque request. The actuation module selectively reduces the expected torque request based on the immediate torque request and a spark capacity. The spark capacity is based on a difference between a first engine torque and a second engine torque, determined at a current airflow. The first engine torque is determined at a first spark advance and the second engine torque is determined at a second spark advance that is less than the first spark advance. The expected torque control module that controls a throttle valve area based on the expected torque request.

International Classification:

B60K 4108

US Classification:

74872

Abstract:

A throttle follower controller for establishing a release throttle position upon the release of the throttle by the vehicle operator which is maintained at a specified value for a predetermined time if the vehicle transmission is experiencing an upshift or if an upshift will occur upon the release of the throttle to provide for a smooth upshift. Upon completion of the upshift or if no upshift will occur upon release of the throttle, a controlled transition of the throttle angle to a predetermined lower coastdown value is established to prevent drive-on while preventing a sudden harsh drive line jerk upon release of the vehicle throttle.

International Classification:

B60K 3100

US Classification:

180197

Abstract:

The ratio air and fuel mixture delivered to the fueled cylinders of an engine of a vehicle is controlled while selective cylinders of the engine are unfueled to reduce engine torque output to inhibit excessive wheel spin during vehicle acceleration. The air/fuel ratio of the mixture delivered to the fueled cylinders is increased as cylinders are selectively unfueled to reduce engine torque output and power enrichment to the fueled cylinders is inhibited when any cylinders are unfueled to reduce engine torque output for traction control and for a time period after all cylinders are again fueled.

International Classification:

B60K 2816
F02D 1704

US Classification:

180197

Abstract:

In a method of traction control, fuel injectors are selectively disabled to unfuel respective cylinders of an engine to reduce engine torque output. The method provides for limiting the number of cylinders that can be disabled for acceleration spin control based on engine and vehicle operating parameters to improve traction control performance and provide protection for the vehicle catalytic converter.
