Description

technical field

[0001] The invention relates to the technical field of automobile testing, in particular to a vehicle speed control method and device used in automobile testing. Background technique

[0002] According to the national standard "GBT 19753-2013 Test Method for Energy Consumption of Light-duty Hybrid Electric Vehicles", when plug-in hybrid electric vehicles are tested for fuel consumption according to the test method, multiple discharges are required at a speed of 50km / h±2km / h To complete the test; at present, some plug-in hybrid models need to perform 3-4h constant-rate discharge treatment at a speed of 50km / h±2km / h to complete the test. Models using the constant speed cruise function are currently tested by manual driving to keep the car at a constant speed of 50km / h±2km / h. Manual driving control has a certain speed fluctuation deviation, which is prone to power consumption errors, resulting in power consumption and Inaccurate calculation of fuel consumption ...
