Embodiment
[0046] In this embodiment, the technical problem to be solved by the present invention is that the current technology can only calibrate the angle sensor to obtain accurate angle signals so as to ensure performance, but this method can only ensure the stability of the new car going straight. For vehicles after time, the mechanical parts of the steering system are worn out and cannot be compensated, and then active deviation occurs. A method and device for correcting the steering wheel angle are provided. The method for correcting the steering wheel angle includes:
[0047] In the initial state of the vehicle, perform zero calibration;
[0048] When the vehicle starts to start, collect the first angle signal;
[0049] storing the first angle signal;
[0050] During the driving process of the vehicle, collect the working condition of the vehicle;
[0051] Judging whether the vehicle is running straight according to the vehicle working condition, if the vehicle is running strai...
