1、To avoid running out of fuel in advance, 5Litre fuel will be reversed, it means that fuel level to be calculated is 5L less than current fuel level. When DTE is less than 50km, DTE is displayed as -”.为防止燃油提前耗尽，续航里程会预留5L的燃油，即用于计算续航里程的燃油 比实际燃油小5L。当续航里程小于50时，续航里程显示“-”。策略 Strategy1) When parameter error
2、, display”-km” or “-miles” DTE cant be reset. 参数错误时，显示“-km”或-miles ”。可续航里程不可复位2) Update frequency: 10 seconds更新频率10s3) Max value: 999km最大显示：999km4) Normally, the displayed value of DTE is gradually changing, variable of this changing is between -1,20km. If variable is more than 20km, DTE shall chang
3、e to the current value directly.DTE is no more than 50km, display -km上升不超过20公里不允许上升，超过20公里，一次性增加到目标值。 DTE小于等于50km,显示-km。5) Formula:计算公式：a) AFC平均油耗b) Use latest 30 km data to calculate AFC_DTE. After re-connect battery, the defaut AFC_DTE is 8.5 Km/L(The default AFC is set by OEM)阶段性油耗：最近30公里的平均油耗。仪表
4、复位后，默认平均 油耗 8.5Km/Lc) 续航里程计算值 Calculated DTE= AFC(latest 30km fuel consumption)(Km/L)*Current Fuel Level(L)*修正值，(修正值为 1) Calculated DTE= AFC(latest 30km fuel consumption)(Km/L) *Current Fuel Level(L)*Factor, (Factor is 1)d) DTE(Max value is 999km)续航里程(最大值999km，内部计算所得 值)e) Displayed DTE续航里程显示Delta va
5、lue= Calculated DTE - Displayed DTE, Approach factor = (DTE_display -( MIN(DTE_calculated，DTE_display) - approaching Factor) / (DTE_calculated - ( MIN(DTE_calculated，DTE_display) - approaching Factor), approaching Factor=10.差值=续航里程计算值-显示续航里程。i. If Displayed DTE =50km, display “-”显示值50km, Display val
6、ue s changing will according to Delta value= Calculated DTE - Displayed DTE 显示值50km时，DTE的变化根据差值确定（差值=计算值显 示值）1. If Delta value W-1,Displayed DTE will increase to change according to Approach Factor. Display DTE decrease value =Travel distance * Approach Factor 差值 W-1 时，显示值按 照变化因子变化，加快下降速率。显示值减少量=行驶距
7、离* 变化因子2. If Delta value=0, no changes.差值=0 时，显示值不变。3. If 1W Delta value20kmDisplayed DTE will decrease to change according to Approach Factor. Display DTE decrease value = Travel distance * Approach Factor1 W差 值0车速等于0，引擎速度大于0时.1. Displayed DTE should decrease according to Fuel Consumption send by E
8、CM.显示值根据ECM发送的耗油量 计算。iv. Once re-fuel is detected, Displayed DTE will equal to Calculated DTE检测到加油时，显示值等于计算值。1. Re-fuel under Ign_On and engine is off, Displayed DTE will increase to Calculated DTE with duration.在 Ign_On 并且发 动机关闭的情况下加油，显示的续航里程会渐变到0实际的续 航里程值2. Refuel under Ign_Off, after Ign_On, Display DTE will change to Calculated DTE directly.在 Ign_Off 的情况下加油， Ign_On后显示的续航里程会直接变成实际值v. Battery re-connect, DTE will reset and re-calculated.断开 KL30 后重新连接，DTE复位并重新计算。
