The invention discloses an LNG vehicle endurance mileage estimation method and vehicle-mounted electronic equipment thereof. The method for estimating the endurance mileage of the LNG vehicle comprises the following steps: acquiring the residual LNG volume Vr in an LNG container of the vehicle; the density rho of LNG is determined; total mileage average gas consumption CTot, subtotal mileage average gas consumption Ctrip and near mileage average gas consumption Crec of the vehicle are determined; and estimating the endurance mileage R based on the residual LNG volume Vr, the density rho, the total mileage average gas consumption CTot, the subtotal mileage average gas consumption Ctrip and the near mileage average gas consumption Crec. According to the LNG vehicle endurance mileage estimation method and the vehicle-mounted electronic equipment thereof, the endurance mileage can be accurately estimated under the condition that the whole vehicle framework is not changed, and the user experience is improved.

    一种LNG车辆续航里程估算方法及其车载电子设备。该LNG车辆续航里程估算方法,其包括:获取车辆的LNG容器内的剩余LNG体积Vr;确定LNG的密度ρ;确定车辆的总里程平均气耗CTot、小计里程平均气耗Ctrip和临近里程平均气耗Crec;以及基于剩余LNG体积Vr、密度ρ、总里程平均气耗CTot、小计里程平均气耗Ctrip和临近里程平均气耗Crec估算续航里程R。本发明的LNG车辆续航里程估算方法及其车载电子设备,其能够在不改动整车架构的情况下,准确估算续航里程,提升了用户体验。
