The invention discloses a vehicle urea consumption monitoring method and system, and relates to the technical field of vehicles. The method comprises the steps: carrying out rigidity detection on a urea pump when surrounding environment information of a vehicle meets a preset environment condition, so as to obtain a rigidity coefficient of the urea pump; determining a dimensionless urea consumption deviation value according to the rigidity coefficient; and when the dimensionless urea consumption deviation value is not within a dimensionless urea consumption standard value range, performing vehicle early-warning prompt according to the dimensionless urea consumption deviation value. Compared with the prior art, the vehicle urea consumption monitoring method needs to monitor a urea liquid level variation value in a urea box in real time, and repeatedly calculate the urea consumption deviation value, so that the urea consumption deviation value is inaccurate; however, the vehicle urea consumption monitoring method carries out rigidity detection on the urea pump of the vehicle to obtain the rigidity coefficient, and then the dimensionless urea consumption deviation value of the vehicleis determined according to the rigidity coefficient, so that the urea consumption of the vehicle can be monitored in real time while the dimensionless urea consumption deviation value of the vehicleis accurately obtained.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and system for monitoring urea consumption of vehicles. Background technique [0002] In the process of vehicle urea system design, the temperature and stability of the liquid level signal are required to accurately calculate the deviation value of urea consumption. The liquid level signal is used to calculate the drop value of the urea liquid level, and then the urea consumption is repeatedly calculated according to the drop value of the liquid level, and finally the difference between the urea consumption and the preset theoretical value of the urea consumption is calculated, and the obtained difference is used as the urea consumption The deviation value of urea consumption greatly increases the complexity of calculating the deviation value of urea consumption, and also leads to inaccurate obtained deviation value of urea consumption. [0003] The above content is on...
