Control apparatus for automobile
First Claim
1. A control apparatus for an automobile, comprising:
- a control unit which controls an electrical operation of a controlled electronic device in the automobile, wherein the control unit includes;
a plurality of terminal pins used, either as input for obtaining exterior control information or as output for sending a control signal to the controlled electronic device;
a ROM provided as a fixed storage section configured to store control software having a terminal pin variable, the control software performing signal input/output control in each of the terminal pins;
a RAM provided as an execution area of the control software;
a rearrangement table storage section configured to store a rearrangement table on a computer readable medium, the rearrangement table showing allocation information for each of the terminal pins; and
a CPU configured to read out the allocation information for each of the terminal pins from the rearrangement table storage section and to substitute the allocation information for each of the terminal pins into the terminal pin variable of the control software at the RAM.

Abstract
In a control apparatus for an automobile with a microcomputer, the control software stores the type of the terminal pin allocated to each control function in the fixed storage section, in a non-fixed state by using a terminal pin variable, in order to alter an allocation arrangement of the terminal pin to the control function. A rearrangement table showing the allocation arrangement of the terminal pin to the control function is stored in a rearrangement table storage section. An allocation content of the terminal pin to each control function is read out from the rearrangement table memory section and specific information of a corresponding terminal pin is substituted into the terminal pin variable corresponding to the each control function included in the control software, based upon the allocation content.

12. A controller for controlling power window units of an automobile, the controller comprising:
-
a CPU; a plurality of terminal pins, a first terminal pin being associated with a first power window unit on the right-side of the automobile, and a second terminal pin being associated with a second power window unit on the left-side of the automobile regardless of a position of a driver'"'"'s seat; a memory configured to store applications on a computer readable medium, a first of the applications establishing a first terminal pin variable and being associated with raising or lowering a window on a driver'"'"'s side of the automobile and a second of the applications establishing a second terminal pin variable and being associated with raising or lowering a window on a passenger'"'"'s side of the automobile; and a rearrangement table configured to store, on another computer readable medium, data for a changeable allocation arrangement of the first and second terminal pins with respect to the first and second applications, the allocation arrangement depending on whether the automobile has a right-hand steering wheel or a left-hand steering wheel; wherein the CPU is configured to read out data for an allocation arrangement from the rearrangement table to define values of the terminal pin variables so that the first terminal pin becomes associated with the first application and the second terminal pin becomes associated with the second application when the automobile has a right-hand steering wheel, and is configured to read out data for another, different, allocation arrangement so that the first terminal pin becomes associated with the second application and the second terminal pin becomes associated with the first application when the automobile has a left-hand steering wheel; and wherein a change in the allocation arrangement of the first and second terminal pins with respect to the first and second applications requires a change to the data stored in the rearrangement table but no change to the first or second application. - View Dependent Claims (15)
