VEHICLE WEIGHT DISTRIBUTION DETERMINATION
Techniques are described for determining weight distribution of a vehicle. A method of performing autonomous driving operation includes determining a vehicle weight distribution that values for each axle of the vehicle that describe weight or pressure applied on a respective axle. The values of the vehicle weight distribution are determined by removing at least one value that is outside a range of pre-determined values from a set of sensor values. The method further includes determining a driving-related operation of the vehicle weight distribution. For example, the driving-related operation may include determining a braking amount for each axle and/or determining a maximum steering angle to operate the vehicle. The method further includes controlling one or more subsystems in the vehicle via an instruction related to the driving-related operation. For example, transmitting the instruction to the one or more subsystems causes the vehicle to perform the driving-related operation.

Control system for a vehicle and method
The invention provides a system (10) for a motor vehicle (100) that receives drive demand information (161S) indicative of an amount of drive demanded of a powertrain (129) of the vehicle (100), and controls an amount of drive torque applied by the powertrain (129) to one or more road wheels (111, 112, 114, 115) in dependence on the drive demand information (116S).
