摘要： A powertrain control method for an internal combustion engine having a throttle responsive to a throttle position command. The method comprises the steps of determining the engine speed, determining the actual throttle position, and generating a desired throttle position value. In one aspect of the invention, the desired throttle position value is generated as a function of the actual throttle position and engine speed. In particular, the throttle position divided by the engine speed can be resolved to a single constant. As such, a simplified powertrain control monitor can be obtained by comparing the throttle position divided by engine speed to a predetermined constant. If the throttle position is greater than the desired throttle position value, the commanded throttle position is limited to the desired value.

摘要： A method and system for providing vehicle control to a driver utilizes an accelerator pedal position and other various inputs. A powertrain control module uses the accelerator pedal position and the other various inputs to give the driver a combination of speed and torque control. In operating a vehicle at speeds ranging from zero to forty-five miles per hour, the powertrain controller provides the driver with torque control by mapping pedal position to electronic throttle angle according to a plurality of predetermined acceleration functions. In operating the vehicle at speeds greater than forty-five miles per hour, the powertrain controller provides the driver with speed control by mapping the electronic throttle angle according to a plurality of predetermined speed functions. Upon receiving other various inputs, the powertrain controller switches control from one form to the other.

摘要： A motor control assembly and method of controlling a motor includes a three phase variable reluctance motor. Each phase includes two separate coils driven by separate driver circuits under the control of a microcomputer. The microcomputer monitors feedback from each driver circuit to determine faults or errors in the driver circuits or respective coils. In the case of a fault detection, one of the driver circuits and coils for each phase may be disabled to allow continued operation of the motor with the remaining driver circuits and coils.

摘要： Systems which progress through a series of states or program steps, such as software controlled computers, are monitored by means of a watchdog timer which samples at least two check bits generated by a system being monitored with the check bits being generated such that only one can change its logic state between valid samples of the check bits. The monitored system is reset if a fault within the system results in an error in the normal sequence through the series of states or program steps such that more than one of the check bits changes from sample to sample. In addition, if the sequence becomes static such that no bits change within the check bits from sample to sample, a time-out will occur which also resets the monitored system. Preferably, the check bits are generated in accordance with Gray code.

摘要： A method and system are provided for positioning a gasoline engine throttle in response to an angular position input command signal. A multi-phase variable reluctance motor positions the throttle in response to motor current commands from a micro-controller. The micro-controller receives and processes the position input command and throttle position feedback signals from a multi-phase variable inductance position encoder rotatably coupled with the motor shaft. The motor current command are obtained from look-up tables that are derived from empirical data of the motor. The motor current command tables are a mapping from motor rotor position and desired motor torque to desired motor currents in the appropriate phases of the motor to hold the load.

摘要： A climate control system and method for preventing exhaust odors from entering the passenger compartment of a motor vehicle. The climate control system includes a duct network and a damper system that is moveable between a fresh air mode and a recirculation air mode. The damper system being moved based at least in part upon a vehicle acceleration condition. During operation, the system is operated in the recirculation air mode during acceleration in a situation that probably has a high concentration of the exhaust odor and gases. The system operates in the fresh air mode when the situation is one that does not have a high probability of a high concentration of exhaust odors and gases.

摘要： A method and system are provided for processing multiple sensor output signals of different ranges/sensitivities so as to provide a seamless transition when switching between the different ranges. More specifically, a determination is made as to whether a selected sensor output range is of a sensitivity higher than a predetermined sensitivity. If the sensitivity is higher, the value of a higher sensitivity sensor output is converted to a value corresponding to the predetermined sensitivity range. An error value is then determined between the converted sensor output value and a sensor output corresponding to a range having the predetermined sensitivity. The sensor output is then modified based on the error value when the control process switches from the selected sensor output to the sensor output corresponding to the predetermined sensitivity. This insures that no glitches will occur in a controller output at the time of switchover.
