    摘要: An on-vehicle DC/DC converter transforms high-voltage electric power originating from an on-vehicle high-voltage source to low-voltage electric power at a regulated voltage level. The low-voltage electric power is distributed by a low-voltage bus. A method for operating the DC/DC converter includes monitoring a state of charge and a temperature of a low-voltage battery connected to the low-voltage bus, setting a DC/DC converter command to a nominal voltage level as a function of the state of charge and temperature of the low-voltage battery, monitoring a total low-voltage electric load, and adjusting the DC/DC converter command to a minimum low-voltage reference voltage when the vehicle is operating below a predetermined speed and the total low-voltage electric load is greater than a predetermined load.

    摘要: A semi-active suspension system that employs magnetically controlled dampers. The semi-active suspension system includes a plurality of sensors that measure vehicle parameters in response to disturbances on the vehicle and provide sensor signals to a central controller. The central controller converts the sensor signals to a flux command signal that is representative of the force on the dampers at each wheel of the vehicle. The flux command signal is sent to a local controller that generates a coil voltage that is applied to a coil within the damper. A flux feedback signal generated by the coil is estimated or measured and is compared to the flux command signal in the local controller to adjust the coil voltage to minimize the difference between the flux command signal and the flux feedback signal to provide a response to the force without a flux delay.

    摘要: A method for improving a failure mode diagnostic of an electric power steering system by overcoming a motor electric lock condition due to position sensor signal corruption or other motor faults. If certain conditions are met, the method determines that the motor is in an electric lock condition, and then reduces a torque current command to the motor so that it is able to be rotated by a vehicle hand-wheel. Once the motor is able to be rotated, then the method determines whether certain conditions have been met to determine whether the position sensor is malfunctioning.
