Problems solved by technology

Such an operation method is not only time-consuming and laborious, but also extremely inconvenient for engineers to operate.
Especially in complex road surfaces and harsh environments such as plateau, high cold, high temperature, etc., conventional laptops cannot operate normally when the test vehicle is driving
In the late stage of vehicle development, in the verification test and durability test stage of small batches of vehicles, the cost of existing data collection methods is too high, and

Description

technical field [0001] The invention belongs to the operation monitoring technology of electronically controlled vehicles, in particular to a device and method for performing wireless remote monitoring calibration and fault diagnosis on electronically controlled vehicles. Background technique [0002] For vehicles with electronic control or integrated electronic control devices, such as electronically controlled gasoline locomotives, electronically controlled diesel locomotives, electronically injected motorcycles, and other electronically controlled engines and powertrain vehicles, the development process of the control unit includes bench tests and road tests. Experiment in two parts. After the basic parameters and algorithms of the control unit are determined through the bench test of the electronically controlled engine, a large number of road tests are carried out on the electronically controlled vehicle to optimize the control unit to achieve the expected goal. At pre...
