If Battery Voltages is Less than the Threshold Values then Circuit should stop

Yes I calculated the Voltage Hysteresis which is 0.22 when the motor is running at full speed and 0.11 when the motors running at low speed

Now I want to include hysteresis in this code of Battery voltage

/BATTERY READINGS VARIABLES
const int Battery = A0;
float Voltage = 0.0; //input battery voltage
float Voltage1 = 0.0; //output voltage for analog pin A0
float R1 = 1590; // R1 =1.590
float R2 = 1000; // R2 =1000
int readValue = 0;
long previousMillis_battery = 0;
byte Bat_start_timer = 0;
int battery_wait;
unsigned long currentMillis = 0;


//BATTERY FUNCTION
void battery(long * previousMillis_battery)
{
 readValue = analogRead(Battery);
Voltage1 = (readValue * 5.0) / 1023;
Voltage = Voltage1 / (R2/(R1+R2));
if(Bat_start_timer == 0) battery_wait = 1000;
  if(currentMillis - *previousMillis_battery > battery_wait) {
     Serial.println(Voltage); Serial.print(",V,");  Serial.print(",Volts,");
  *previousMillis_battery = currentMillis;
    battery_wait = 1000; Bat_start_timer = 1; }
} // battery FUNCTION END

void setup()
{
  Serial.begin(9600);
  pinMode(Battery, INPUT);
  }

void loop()
{
     currentMillis = millis();
    battery(&previousMillis_battery);
}

Can anyone help me to add hysteresis which is 0.22 in this code and define voltages greater than 11. 6 volts and less than 11.6 volts ?
