A control system, for a vehicle, is configured to receive a sensor signal 42 output by a sensor, e.g. camera, lidar, ultrasonic, radar etc., of the vehicle and receive or generate a sensor degradation signal 44 indicative of a degradation in sensing performance of the sensor. The control system also receives or determines a degradation time 46 at which the sensing performance of the sensor degraded and generates an estimated sensor output 48 in dependence on the sensor signal at or before the degradation time. The control system generates a confidence score 50 associated with the estimated sensor output. Sensing performance may be degraded by, for example, a second vehicle causing a splash in front of the vehicle so that a camera outputs a degraded signal. In addition fog or smoke may degrade the signal. Reference is also made to a method, a vehicle and a non-transitory computer readable medium.
