Abstract
A non-volatile memory device 80 or 800 is provided, wherein intrinsic information indicating variances of characteristics of individual units is stored in advance in the inexpensive memory device 80 or 800 through a simple processing procedure with a view to adjusting a control quantity with high accuracy upon ordinary control by executing software with a microcomputer 55A or 300A. Thus, a control system for a motor vehicle exhibiting excellent performances can be implemented at low costs, which allows accurate and precise adjustment to be realized through a simplified adjusting step while reducing an extraneous space for adjustment of variance without need for use of any specific part of high precision.
Claims17
A control system for a motor vehicle comprising a control unit, said control unit comprising:
- a non-volatile memory device, control means for arithmetically determining a desired control quantity for the motor vehicle by using information stored in said memory device, and
- an input control unit and an output control unit provided in association with said control means, wherein intrinsic information corresponding to characteristics of said control unit which is measured during adjustment of the control unit is stored in said memory device, and said control means corrects said desired control quantity on the basis of said intrinsic information.
A control system for a motor vehicle comprising:
- a control unit including a non-volatile memory device, control means for arithmetically determining a desired control quantity for the motor vehicle by using information stored in said memory device, and an input control unit and an output control unit provided in association with said control means,
- an input unit connected to said control means by way of said input control unit, and
- an output unit connected to said control means by way of said output control unit, wherein
- intrinsic information corresponding to characteristics of at least one of said control means, said input control unit, said output control unit, said input unit and said output unit is stored in said memory device, and
- said control means includes correcting means for correcting said desired control quantity on the basis of said intrinsic information.
