Claim One:
1. A lane recognition system for a vehicle, comprising: a camera set picking up a road image of a road ahead of the vehicle; a memory storing parameters representative of a model lane marker of the road image; and a controller coupled to the camera set and the memory, the controller being arranged, to set a plurality of lane-marker candidate-point detecting areas on the road image so that each one of the lane-marker candidate-point detecting areas is partially overlapped with the lane-marker candidate-point detecting areas adjacent to the one of the lane-marker candidate-point detecting areas, to detect each lane marker candidate point in each lane-marker candidate-point detecting area, to calculate variations of the parameters by comparing the lane marker candidate points with corresponding points on the model lane marker derived from the parameters stored in the memory, to correct the parameters according to the variation, to output road-shape indicative information on the basis of the parameters.
