The present disclosure is related to enhanced vehicle localization using speed bump detection. In some examples, a vehicle of the present disclosure can estimate its location using GNSS and/or dead reckoning techniques. However, especially in scenarios where GNSS reception is poor, the uncertainty in the vehicle's location can be too large to accurately control the vehicle in a fully- or partially-autonomous driving mode. To reduce uncertainty in the vehicle's location, the vehicle can locate one or more features included in map information received by or stored on the vehicle. In some embodiments, a speed bump is included in the map information. The speed bump can be detected by one or more sensors, such as a motion sensor or one or more suspension level sensors, of the vehicle. The vehicle can determine its location using the detected position of the speed bump and the map information.
