Claim 8:
9. A data collecting method for an electric vehicle, incorporated with a data collecting system for the electric vehicle, the data collecting system comprising a component arranged in the electric vehicle, a data collector connected with the component through a bus of the electric vehicle, and a debug server connected with the data collector, and the data collecting method comprising:
a) continuously collecting, by the component, a regular data of a component data of the component and performing a regular data sending procedure to send the regular data to the bus in accordance with a regular frequency;
b) determining, by the component, whether a triggering condition is satisfied based on the component data;
c) continuously collecting, by the component, a high-speed data of the component data after the component data is determined to satisfy the triggering condition, and performing a high-speed data sending procedure to send the high-speed data to the bus in accordance with a high-speed frequency, wherein the high-speed frequency is higher than the regular frequency;
d) continuously collecting, by the component, a high-resolution data of the component data, and temporarily storing the high-resolution data to a register;
e) determining, by the component, whether an error occurs based on the component data;
f) storing, by the component, the high-resolution data temporarily stored in the register and continuously collected, to a component storage unit, when the error occurs;
g) after the step f), performing, by the component, a high-resolution data sending procedure to send the high-resolution data being stored to the component storage unit at a time point when the error occurs, being stored to the register within a first time period before the error occurs, and being stored to the component storage unit within a second time period after the error occurs, from the component storage unit to the bus, wherein the high-resolution data comprises a time information;
h) performing, by the data collector, a full sampling procedure to a bus data of the bus, wherein the full sampling procedure is performed to obtain all the bus data respectively sent from different components of the electric vehicle to the bus in accordance with different procedures, and the bus data comprises the regular data, the high-speed data, and the high-resolution data;
i) associating, by the data collector, the sampled bus data with a correct time to generate an uploading data;
j) receiving, by the debug server, the uploading data from the data collector; and
k) comparing, by the debug server, the uploading data with multiple pre-stored error patterns and displaying a comparison result immediately.
