- Step 303 Control the vehicle to maintain or exit the automatic driving mode according to the first turn signal and the holding information.
- the moment targeted by the holding information should be close to the moment when the first turn signal is generated.
- the time difference between the moment targeted by the holding information and the moment when the first turn signal is generated should be less than the preset time threshold.
- the moment targeted by the holding information can be understood as follows: if the holding information indicates that the steering wheel is held at the first moment, the first moment is the moment targeted by the steering wheel; if the holding information indicates that the steering wheel is held at the second moment, the second moment is the moment targeted by the steering wheel. Since the time for the first turn signal to be transmitted between the steering sensor and the automatic driving controller is very short and can be ignored, the automatic driving controller can use the moment when the first turn signal is received as the moment when the first turn signal is generated.
- the automatic driving controller when receiving the first turn signal, can determine whether the steering wheel is held according to the holding information. If the holding information indicates that the steering wheel of the vehicle is held, the vehicle is controlled to exit the automatic driving mode. After exiting the automatic driving mode, the driving of the vehicle is taken over by the driver.
