Method and system of modifying a mapping of throttle pedal input to torque demand, comprising the steps of identifying a pull-away, assessing the pull-away against a criterion, and when the pull-away is assessed as meeting the criterion, information related to captured throttle pedal position during the pull-away is used to modify the mapping. Modifying the mapping may include modifying one or more pedal scalars. Preferably, the criterion is wheel spin, throttle pedal position, duration of the pull-away or gradient, wherein the criterion is assessed against a threshold value. Assessment may be achieved analysing the traction control data during the pull-away. Alternatively, an anomaly detection algorithm could be utilised, wherein the algorithm uses Gaussian distributions trained on throttle pedal position data captured during prior pull-aways. Assessment could also be determining, from the throttle pedal input, whether the driver’s reaction to the pull-away was consistent with a reaction from previous pull-aways. The mapping could be for a low friction mode.
