本申请涉及一种续航里程估算方法、增程器控制方法和系统。所述方法应用于整车控制器,包括:获取预设的至少一个距离阈值以及当前车辆每行驶一个距离阈值所需的油耗阈值和电耗阈值;获取当前车辆每行驶一个距离阈值实际产生的当前油耗和当前电耗;根据各个当前油耗更新各个油耗阈值,根据各个当前电耗更新各个电耗阈值;根据更新后的各个油耗阈值的平均值得到目标油耗,根据更新后的各个电耗阈值的平均值得到目标电耗,根据目标油耗和目标电耗得到等效油耗;当监测到剩余燃油为零时,根据等效油耗和预设的油量阈值得到剩余续航里程。采用本方法能够对现有技术中在燃油即将燃尽时所作的措施进行完善。
The invention relates to an endurance mileage estimation method, a range extender control method and a range extender control system. The method is applied to a vehicle control unit and comprises the steps that at least one preset distance threshold value and an oil consumption threshold value and a power consumption threshold value needed when a current vehicle travels for each distance threshold value are obtained; acquiring the current oil consumption and the current power consumption actually generated when the current vehicle runs for each distance threshold value; updating each fuel consumption threshold value according to each current fuel consumption, and updating each power consumption threshold value according to each current power consumption; target fuel consumption is obtained according to the updated average value of the fuel consumption threshold values, target power consumption is obtained according to the updated average value of the power consumption threshold values, and equivalent fuel consumption is obtained according to the target fuel consumption and the target power consumption; and when it is monitored that the residual fuel oil is zero, the residual endurance mileage is obtained according to the equivalent oil consumption and a preset oil quantity threshold value. By the adoption of the method, measures taken when fuel oil is about to be burnt out in the prior art can be perfected.
