摘要:
The present invention aims to provide a control system which is capable of building high-precision current detecting means in a single-chip LSI and can be realized at a lower cost, and a semiconductor device used in the control system. Drive circuits are provided inside the same semiconductor chip. The drive circuits are equipped with: current detecting shunt resistors each of which is provided in each of the drive circuits and detects a current flowing through a load, the current detecting shunt resistors being provided within a semiconductor chip by the same process; a dummy resistor provided within the semiconductor chip by the same process as the current detecting shunt resistors; and a calibration reference externally attached to the semiconductor chip and connected to the dummy resistor. A correcting means corrects the values of currents that flow through the current detecting shunt resistors, using the dummy resistor and the calibration reference.

An object of the present invention is to provide a mechanically and electrically integrated type electronic control apparatus which can be embedded in a compact mechanical part, and has a compact structure while having a high wiring freedom, a high heat dissipation and a high reliability. In a mechanically and electrically integrated type electronic control apparatus provided with a control signal generating part, and an angular wiring member connecting the control signal generating part and a controlled part controlled by a control signal of the control signal generating part, installed within a conductive casing, at least the wiring member has a fixed hole, a surface including the fixed hole is coated in an insulative manner, and the fixed hole is fixed to the conductive casing mechanically while keeping an insulating property.

Disclosed is a hydraulic control module that can be downsized. The hydraulic control module includes an upper control valve, a lower control valve, and a wiring plate. The upper and lower control valves each include an oil path having a groove portion. A sandwich structure is employed so that the wiring plate is sandwiched between the upper and lower control valves. The wiring plate has a groove portion or a through-hole that is in communication with the at least one of the groove portion of the upper control valve and the groove portion of the lower control valve.

Program data stored in the recording medium of a general control apparatus coupled to a network is stored in the recording medium of a control apparatus as a rewritten subject of program data in the following manner. First, program data stored in a recording medium contained within the general control apparatus is sent via the network of a vehicle to the recording medium of a second control apparatus as the rewritten subject of program data (see a path L1). In this case, the program data 21 stored in the recording medium contained in the general control apparatus for generally controlling the control apparatuses is sent to the network of the vehicle when it is determined to be optimum by the CPU 12c of the general control apparatus. The program data sent to the network of the vehicle is sent via the network of the vehicle to the second control apparatus as the rewritten subject of program data. Then, the second control apparatus as the rewritten subject of program data stores the program data sent via the network of the vehicle into the recording medium.
