摘要:
A request heat calculation unit calculates a request heat power requested to heat sources to supply. A heat cost calculation unit calculates a relationship between a heat power supplied from each of the heat sources and a heat cost, which is a fuel quantity consumed to supply a unit heat power. An abnormal source detection unit detects an abnormal heat source, which cannot normally supply a heat power, from the heat sources. An abnormal heat calculation unit calculates an abnormal heat power supplied from the abnormal heat source. A determination unit determines distribution of heat power supplied from the heat sources based on both the relationship and the abnormal heat power, such that a sum of the heat power supplied from the heat sources coincides with the request heat power, and the heat cost of all the heat sources is minimized.

Tire-uniformity components may generate a rotating force on the vehicle, when the vehicle is in a turning movement. The rotating force may spoil or deteriorate a turning performance of the vehicle. The controller controls a motor of an electric power steering system to modulate an assist torque acting on steerable wheels in accordance with the tire-uniformity components. The assist torque is modulated in the same direction as the rotating force. As a result, it is possible to suppress a deterioration of the turning performance of the vehicle.

A vehicle integration control system includes a manager controller and a driving system controller. The manager controller sets a target generation driving force guide value for a driving force outputted from a driving system of a vehicle. The driving system controller controls the driving force on the basis of the target generation driving force guide value. The manager controller includes a driver request value setter and a driving force corrector. The driver request value setter sets a driver request generation driving force value corresponding to the driving force outputted from the driving system on the basis of a driver's input. The driving force corrector corrects the driver request generation driving force value on the basis of a predetermined program to restrain vibration generated in the vehicle when the driving force outputted from the driving system.

In a driving condition control system, a sensing unit is configured to sense a first physical quantity indicative of a rotation of the first rotatable axle assembly and a second physical quantity indicative of a rotation of the second rotatable axle assembly. A correcting unit is configured to correct the torque according to the sensed first and second physical quantities of the rotations of the first and second rotational axle assemblies. This allows the torque to be precisely obtained.

In a power steering apparatus employing an EPS (electrical power steering) motor coupled to a steering mechanism, when vibration of the steering mechanism is produced by twisting of tire rubber due to changes in steering angle, resultant pulsation of the drive current of the EPS motor are suppressed by adding to the drive current a current that is of equal frequency and opposite phase to the pulsation. Vibration of the EPS motor shaft, and resultant vibration of the steering wheel and vehicle body, are thereby effectively suppressed.

An integrated vehicle control system includes various functionalized networks, such as power train group, vehicle motion group, and power source group, each including a plurality of ECUs connected via an individual communication line. A managing ECU in each network determines operation directives to be supplied to individual ECUs belonging to its own network based on information obtained from these individual ECUs as well as information obtained from other ECUs of different networks via a host communication line L4. The determined operation directives are transmitted to corresponding ECUs to cause respective individual ECUs to operate subordinately according to the given operation directives, thereby realizing a collective control of specific functions. The managing ECU also executes abnormality detection processing for detecting abnormality occurring in the integrated vehicle control system.

The SOI substrate 1 has a supporting substrate 10, an insulating layer 20 formed on the supporting substrate 10 and a silicon layer 30 formed on the insulating layer 20. A through electrode 40 is provided in a device formation region A1 of the SOI substrate 1. The through electrode 40 reaches the insulating layer 20 from the silicon layer 30. Specifically, the through electrode 40 extends to an inner part of the insulating layer 20 originating from a surface of the silicon layer 30 while penetrating the silicon layer 30. Here, an end face 40a of the through electrode 40 at the insulating layer 20 side stops inside the insulating layer 20.
