求助大神看看我的程序的錯(cuò)誤或給一份發(fā)動(dòng)機(jī)檔位加減檔算法設(shè)計(jì)及仿真圖及程序
主要程序代碼如下：
//預(yù)處理數(shù)據(jù)
#define CAR_MAX 130
#define TORQUE_MAX 1.25
#define ROTATE_MAX 2550
#define Economy_rpm_MIN 1000
#define Economy_rpm_MAX 1300
struct InputData Preproccess(struct InputData sinputData)//將接收的數(shù)據(jù)限制在一定范圍內(nèi)
{
sinputData.car_speed = (CAR_MAX < sinputData.scar_speed) ? CAR_MAX : sinputData.car_speed;
sinputData.rotate_speed = (ROTATE_MAX < sinputData.rotate_speed) ? ROTATE_MAX : sinputData.rotate_speed;
sinputData.torquePercent = (TORQUE_MAX < sinputData.torquePercent) ? TORQUE_MAX : sinputData.torquePercent;
return sinputData;
}
//計(jì)算當(dāng)前檔位
int ShiftNow(float scar_speed, float srotate_speed, unsigned int Key)//計(jì)算當(dāng)前檔位,從6檔以上考慮
{
//15.53 12.08 9.39 7.33 5.73 4.46 3.48 2.71 2.1 1.64 1.28 1
gearRadio = 480.255 * srotate_speed / Key / car_speed;//計(jì)算齒輪比
int shift_now = 0;
if ((gearRadio>4.31) && (gearRadio<4.61))
{
shift_now = 6;
}
else if ((gearRadio > 3.33) && (gearRadio < 3.63))
{
shift_now = 7;
}
else if ((gearRadio>2.56) && (gearRadio < 2.86))
{
shift_now = 8;
}
else if ((gearRadio>1.95) && (gearRadio < 2.25))
{
shift_now = 9;
}
else if ((gearRadio>1.49) && (gearRadio < 1.79))
{
shift_now = 10;
}
else if ((gearRadio>1.13) && (gearRadio < 1.43))
{
shift_now = 11;
}
else if ((gearRadio>0.85) && (gearRadio < 1.15))
{
shift_now = 12;
}
else
shift_now = 0;//當(dāng)前檔位值初始化為0，將丟棄該點(diǎn)的所有值
return shift_now;
}
//計(jì)算換擋狀態(tài)值，3表示不換擋，4表示升檔，5表示降檔
int ComputeShiftState(float srotate_speed)//計(jì)算換擋狀態(tài)
{
if((srotate_speed>=Economy_rpm_MIN)&&(srotate_speed<= Economy_rpm_MAX))
{
shiftState =3;//不換檔
}
else if (srotate_speed > Economy_rpm_MAX)
{
shiftState = 4;//升檔
}
else if (srotate_speed < Economy_rpm_MIN)
{
shiftState = 5;//降檔
}
else
{
shiftState = 3;
}
return shiftState ;
}
