A method of controlling an actuator includes developing a sequence of actuation commands S(t)=C(t, t), C(t, t), . . . , C(t, t) obtained from data sensed before time tfor controlling the actuator at different time intervals (t, t), (t, t), . . . , (t, t). The sequence of actuation commands is transmitted to and stored in memory of an actuation ECU, which then applies the actuation command for time interval (t, t). If a fault affects a sensor, a control ECU or data communication therebetween, the actuation ECU will not receive an updated sequence of actuation commands S(t) at time t. If the updated actuation command sequence, the actuation ECU applies the actuation command for the time intervals (t, t), . . . , (t, t) from the sequence of actuation commands S(t) that is stored in the memory of the actuation ECU.

Method and system for limited time fault tolerant control of actuators based on pre-computed values

A method of dynamically reconfiguring a distributed computing architecture having a plurality of processing nodes, where each processing node hosts a respective plurality of virtual machines, includes detecting a fault condition on a first processing node, assessing the criticality of a software function performed by each of the respective virtual machines on the first processing node, and reassigning at least one of the plurality of virtual machines on the first processing node to a second processing node if the at least one virtual machine is deemed critical.

Distributed computing architecture with dynamically reconfigurable hypervisor nodes

A control system for selectively lighting and/or highlighting a control interface for a specific individual function generally includes at least one sensor for detecting at least one condition; a controller in operative communication with the at least one sensor and the control interface; wherein the controller sends an output signal to the control interface in response to detecting the at least one condition, wherein the output signal is effective to light and/or highlight the control interface for the specific individual function. Methods for operating the control system are also discussed.

Sensor based anticipatory lighting of controls

A system for controlling fluid flow about a vehicle. The system comprises a fluid flow control device, an obstacle sensor for detecting obstacles, and a controller. The fluid flow control device has a body with at least one surface and an actuation means in operative communication with the surface. The actuation means is operative to alter at least one attribute of the fluid flow control device in response to a control signal. The controller has control logic for generating the control signal in response to the obstacle sensor.

Control logic for fluid flow control devices

An extendible bumper system for a vehicle includes a controller system configured to: determine a distance of travel of a first end of a bumper structure using a signal from a position sensor in a first motor, determine a distance of travel of a second end of the bumper structure using a signal from a position sensor in a second motor, and independently adjust at least one of rotational speed and torque output of rotors in the first and second motors in response to the distances of travel. The rotational speed or torque output of the first and second rotors may be independently adjusted in response to a difference in the distances of travel of the first and second ends of the bumper structure, and the rotational speed or torque output of the first and second rotors may be accelerated or decelerated during predetermined distances of travel. A bumper energy absorber for supporting the bumper structure relative to a vehicle includes an inner tube, outer tube, lead screw, nut and motor. Rotation of the lead screw by the rotor causes translation of the nut along the lead screw for driving at least a portion of the bumper structure between extended and retracted positions.
