Application ID: 08278130

Base Claim:
1. A vehicle control system using an object program for a vehicle automatic transmission based on operating conditions of a vehicle, comprising: a microcomputer mounted in the vehicle; source program generating means for generating a source program, while determining parameters to be used in the source and a control algorithm through simulation on a mainframe computer; storage means, operably connected to said source program generating means, for storing the source program containing expressions employing the variable; detection means, operably connected to said storage means, for detecting expressions containing at least a quantization factor with floating-point arithmetic from among said expressions; conversion means, operably connected to said detection means, for converting the expressions detected by said detecting means into a microcode, which is loaded into the microcomputer of the vehicle, containing at least a quantization factor without floating-point arithmetic using a prescribed method of notation; arithmetic means, operably connected to said conversion means, for multiplying the variables of the microcode containing at least a quantization factor without floating-point arithmetic converted by the conversion means by prescribed values obtained from the expressions containing at least a quantization factor with floating-point arithmetic to convert into the object program including the microcode multiplied by the prescribed value; and loading means for loading the object program on the microcomputer, wherein said microcomputer determines a gear shift scheduling by using the object program in response to the operating conditions of the vehicle.
