Vehicle localization becomes challenging in GNSS-denied environments due to the accumulation of dead-reckoning errors. A learning-based yaw-error compensation method using only vehicle speed and yaw-rate signals is presented. Temporal features are extracted by a CNN-LSTM, and multiple experts generate candidate yaw-error estimates. These estimates are combined through deterministic interpolation in the speed and yaw-rate state space to reflect state-dependent error characteristics. The predicted yaw error is used to correct the dead-reckoning heading and reconstruct the vehicle trajectory during GNSS outages. Experiments on low-speed driving data confirm that the proposed method reduces accumulated localization error and improves trajectory estimation performance.
