摘要:
A throttle control system for a vehicle includes a driver input that generates a control signal and a control module that generates a throttle control signal based on the control signal. The control module determines whether the throttle control signal is within one of a first and a second region, determines a compensation factor from a first look-up table when the throttle control signal is within the first region and determines the compensation factor from a second look-up table when the throttle control signal is within the second region. The control module calculates a compensated throttle control signal based on the compensation factor.

Methods and apparatus are provided for ensuring that a throttle increase accompanying a change in the number of active cylinders of an internal combustion engine will not occur too long with more than a selected fraction of all the cylinders activated, so as to not startle a driver. The apparatus comprises an electronic controller that generates the throttle increase if less than all the cylinders are requested to be activated. A determination is made as to whether the number of cylinders being fueled is equal to or less than the selected fraction. A timer is started if the number of cylinders being fueled is greater than the selected fraction. The throttle increase is turned off if the amount of time measured by the timer exceeds a threshold before the number of cylinders being fueled becomes either less than or equal to the selected fraction.

An exemplary transmission system includes a first sensor configured to measure a quantity and output a first signal representative of the quantity measured. A second sensor is configured to separately measure the quantity measured by the first sensor and output a second signal representative of the quantity measured. A transmission control module in communication with the first sensor and the second sensor is configured to process the first signal along a primary processing path, process the second signal along a secondary processing path, compare the processed first signal to the processed second signal to determine if the primary processing path is reliable, and compare the processed first signal to the processed second signal to determine if the first sensor is reliable.

A redundant position sensing system includes a device having a position between minimum and maximum positions. First and second sensor modules include first and second sensor resistances. A value of one of the first or second sensor resistances increases and a value of the other of the first or second resistances decreases when the device moves from the minimum position to the maximum position. A maximum value of the first sensor resistance ranges between a first maximum value and a second maximum value that is greater than the first maximum value due to a first manufacturing tolerance. A maximum value of the second sensor resistance ranges between a third maximum value and a fourth maximum value that is greater than the third maximum value due to a second manufacturing tolerance. The second maximum value is less than the third maximum value.

Receiving sensor data related to position of a gear in a transmission, the sensor data including data from a first sensor and data from a second sensor; determining a first indicated position of the gear from the data from the first sensor; determining a second indicated position of the gear from the data from the second sensor; comparing the first indicated position to the second indicated position; and determining based on the comparison a gear engagement status of the gear.
摘要:
An exemplary system includes at least one valve configured to control fluid flow in a dual-clutch transmission system. A solenoid is operably connected to the at least one valve and configured to move the valve to a plurality of positions. A primary processing unit is in communication with the solenoid and configured to determine an intended position of the valve. A controller is configured to receive the intended position of the valve from the primary processing unit and generate a primary control signal associated with the intended position of the valve. The solenoid is configured to move the valve to the intended position based on the primary control signal. A secondary processing unit is configured to receive information from the primary processing unit and prevent the primary control signal from controlling the solenoid if the primary processing unit is unable to control the solenoid.
