The invention discloses a retarder parameter determination method and device, equipment and a storage medium. The method comprises the steps that when a vehicle is in a running state and a retarder is in a non-working state, if the difference value between the current retarder heat dissipation power and a retarder heat dissipation power threshold value is larger than a first threshold value, and the difference value between the current retarder oil temperature and a retarder oil temperature threshold value is larger than a second threshold value, the retarder is in a working state, and the retarder is in a non-working state; the current voltage of the cooling liquid temperature sensor and the current voltage of the oil temperature sensor are obtained; querying an oil temperature sensor chart based on the current voltage of the coolant temperature sensor to obtain a target retarder oil temperature; the cooling liquid temperature sensor chart is inquired on the basis of the current voltage of the oil temperature sensor, and the target cooling liquid temperature is obtained.By means of the technical scheme, the situation that due to the fact that the sensors are reversely connected, the cooling liquid temperature received by the controller is too high, and therefore wrong overtemperature alarming is conducted, and the vehicle safety problem is further caused can be prevented.

    本发明公开了一种缓速器参数确定方法、装置、设备及存储介质。该方法包括:当车辆处于行驶状态,且缓速器处于未工作状态时,若当前缓速器散热功率和缓速器散热功率阈值的差值大于第一阈值,且当前缓速器油温与缓速器油温阈值的差值大于第二阈值,则在缓速器处于工作状态时,获取冷却液温度传感器的当前电压和油温传感器的当前电压;基于冷却液温度传感器的当前电压查询油温传感器图表,得到目标缓速器油温;基于油温传感器的当前电压查询冷却液温度传感器图表,得到目标冷却液温度,通过本发明的技术方案,能够防止出现由于传感器接反,导致控制器接收到的冷却液温度过高,从而错误的超温报警,进而引发车辆安全的问题。
