The invention relates to the technical field of automobile control, in particular to a method and a system for correcting electric quantity displayed by an electric automobile instrument. Comprising the steps that after a vehicle is powered on, whether a current real electric quantity value needs to be corrected or not is judged based on vehicle standing time, and a real electric quantity correction value is obtained; calculating a power-on state display electric quantity correction value based on the real electric quantity correction value and the current dischargeable capacity of the battery; judging whether the power-on state display electric quantity needs to be corrected or not based on the power-on state display electric quantity correction value and the display electric quantity value, and displaying the power-on state display electric quantity correction value when correction is needed; and after the vehicle is under high voltage, calculating a high-voltage state display electric quantity correction value based on the current real electric quantity value, and updating according to the calculated high-voltage state display electric quantity correction value in real time. The method for correcting the electric quantity displayed by the electric automobile instrument is very simple, the electric quantity display precision can be greatly improved, and the driving feeling of a user is improved.

    本发明涉及汽车控制技术领域,具体地指一种电动汽车仪表显示电量修正方法及系统。包括,车辆上电后,基于车辆静置时间判断是否需要对当前真实电量值进行修正,获取真实电量修正值;基于真实电量修正值和当前电池可放电容量计算上电状态显示电量修正值;基于上电状态显示电量修正值和显示电量值判断是否需要对上电状态显示电量进行修正,并在需要修正时显示上电状态显示电量修正值;车辆上高压后,基于当前真实电量值计算高压状态显示电量修正值,并实时按照计算的高压状态显示电量修正值进行更新。本申请的电动汽车仪表显示电量修正方法非常的简单,能够大幅度提高显示电量精度,提升用户驾驶感受。
