  • Method of estimating a vehicle load
    Patent number: 11485371
    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.
    Type: Grant
    Filed: July 2, 2019
    Date of Patent: November 1, 2022
    Assignee: JAGUAR LAND ROVER LIMITED
    Inventors: Thomas Owen, Roger Wardle, David Parry
  • Control of a vehicle having an automatic transmission to compensate for ambient air density
    Patent number: 11261958
    Abstract: Control of a Vehicle Having an Automatic Transmission to Compensate for Ambient Air Density A method of controlling an automatic transmission (24) of a vehicle (10), the method comprising: receiving a signal indicative of a vehicle operating mode; obtaining a base map defining gear shift points for the transmission (24) based on the indicated vehicle operating mode; obtaining a torque loss map defining gear shift points for the transmission (24) based on a predetermined minimum value of density; and controlling the transmission (24) based on the base map if the base map defines gear shift points at higher engine speeds or vehicle speeds than the corresponding gear shift points defined by the torque loss map.
