Abstract
A method of estimating a load on a vehicle (10), 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.
Claims19
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;
- analyzing characteristics of the first load estimate and the second load estimate;
- based on the analysis selecting either the first load estimate or the second load estimate as an output load estimate;
- outputting the output load estimate;
- and
- receiving at least one signal indicative of vehicle operating parameters and inhibiting the first load estimation technique and/or the second load estimation technique in dependence on the at least one signal indicative of the vehicle operating parameters.
A controller configured to control a vehicle automatic transmission, the controller comprising a processor configured to:
- obtain a first load estimate using a first load estimation technique;
- obtain a second load estimate using a second load estimation technique;
- analyze characteristics of the first load estimate and the second load estimate;
- based on the analyzed characteristics, select either the first load estimate or the second load estimate as an output load estimate;
- and
- output the output load estimate,
- wherein the processor is further configured to receive at least one signal indicative of vehicle operating parameters and inhibit the first load estimation technique and/or the second estimation technique in dependence on the at least one signal.
