The present invention discloses a method and device for detecting vehicle deviation from a lane. The method comprises the steps of generating a first image signal through a linear array image sensor installed on a vehicle according to lane line situations and lane situations in front of the vehicle and generating a second image signal according to the lane line situations and the lane situations in front of the vehicle a preset time after the first image signal is generated; generating an absolute value of a lane line slope according to the first image signal and the second image signal, judging that the vehicle deviates from a lane when the absolute value of the lane line slope is larger than a preset threshold value, and generating vehicle lane-deviation information; and outputting the vehicle lane-deviation information. According to the method and the device, the image signals are generated by the linear array image sensor, the data size is small, the processing speed is high, an image output frame rate is high, the extendibility is good, the cost is low, the detection is simple and easy to realize, and alarms can be timely and accurately given.
