An apparatus and method, for estimating confidence in a vehicle reference velocity, comprises a controller having an electronic processor 21 for receiving at least one first vehicle operating parameter, such as vehicle acceleration. The electronic processor 21 is configured to access a memory device 23 and execute instructions stored therein such that it is operable to monitor the at least one first vehicle operating parameter; and to calculate a confidence value representing the confidence in the vehicle reference velocity, the confidence value being calculated in dependence on the vehicle operating parameter. The reference velocity is calculated from the wheel speed signals WS1-4, either by the processor 21 or a separate processor. A sensor 15 is provided to output a throttle pedal position signal S1. A pressure sensor 17 is provided to output a brake pressure signal S2. A steering wheel angle sensor 19 is provided to output a steering angle signal S3. |
