求助大神看看我的程序的錯誤或給一份發動機檔位加減檔算法設計及仿真圖及程序
主要程序代碼如下：
//預處理數據
#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)//將接收的數據限制在一定范圍內
{
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;
}
//計算當前檔位
int ShiftNow(float scar_speed, float srotate_speed, unsigned int Key)//計算當前檔位,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;//當前檔位值初始化為0，將丟棄該點的所有值
return shift_now;
}
//計算換擋狀態值，3表示不換擋，4表示升檔，5表示降檔
int ComputeShiftState(float srotate_speed)//計算換擋狀態
{
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 ;
}
