The invention is suitable for the technical field of automobiles, and provides a power determination method and device, a vehicle-mounted terminal and a vehicle. The method comprises the steps that the first torque of a motor of the vehicle and the second torque of a hydraulic braking system of the vehicle are obtained; based on the first torque and the second torque, the working state of the vehicle is determined; determining a calculation strategy of the actual power proportion of the vehicle based on the working state; calculating to obtain an actual power proportion based on the calculation strategy; an actual power is determined based on the actual power ratio. Compared with the prior art that the actual power of the vehicle is calculated simply according to the actual torque of the motor of the vehicle, due to the fact that the vehicle has hydraulic braking force in actual application, the method combines the actual torque (namely the first torque) of the motor of the vehicle with the actual torque (namely the second torque) of the hydraulic braking system, and the actual power of the vehicle is calculated. The actual power of the vehicle can be accurately calculated, so that the calculation accuracy of the actual power is improved.
本申请适用于汽车技术领域,提供了一种功率确定方法、装置、车载终端及车辆,所述方法包括:获取车辆的电机的第一扭矩和车辆的液压制动系统的第二扭矩;基于第一扭矩和第二扭矩,确定车辆的工作状态;基于工作状态,确定车辆的实际功率比例的计算策略;基于计算策略,计算得到实际功率比例;基于实际功率比例确定实际功率。与现有技术只是简单地根据车辆的电机的实际扭矩来计算车辆的实际功率相比,由于在实际应用中,车辆存在液压制动力,因此,本方法结合车辆的电机的实际扭矩(即第一扭矩)和液压制动系统的实际扭矩(即第二扭矩),可以准确计算得到车辆的实际功率,从而提高了对实际功率的计算准确率。
