A method of estimating a load on a vehicle (), the method comprising: obtaining a first load estimate using a first load estimation technique; obtaining a second load estimate using a second load estimation technique; analysing characteristics of the first load estimate and the second load estimate; and, based on the analysis selecting either the first load estimate or the second load estimate as an output load estimate.

Method of estimating a vehicle load

A controller for a motor vehicle includes means for receiving information indicative of a current vehicle speed; means for receiving information indicative of an amount of brake force a braking system is developing or is capable of developing; means for receiving information indicative of a gradient of a driving surface on which the vehicle is driving; and torque transmission reduction means for causing a powertrain torque reduction operation to be performed in which the controller causes one or more components in a torque transmission path from a torque delivery device to driven wheels to assume a torque reduction condition in which torque transmission is reduced or substantially terminated. The controller is configured automatically to cause the torque reduction operation to be performed in dependence at least in part on the information indicative of current vehicle speed, information indicative of brake force amount and information indicative of driving surface gradient.
