  • Patent number: 9660299
    Abstract: A method and system for strain-based estimation of the state of health of a battery, from an initial state to an aged state, is provided. A strain gauge is applied to the battery. A first strain measurement is performed on the battery, using the strain gauge, at a selected charge capacity of the battery and at the initial state of the battery. A second strain measurement is performed on the battery, using the strain gauge, at the selected charge capacity of the battery and at the aged state of the battery. The capacity degradation of the battery is estimated as the difference between the first and second strain measurements divided by the first strain measurement.

  • Patent number: 9429628
    Abstract: A method and system for application independent map-based cycle life testing of battery cells is provided. A target depth of discharge (DOD) and a charge/discharge current level is selected for the battery test. The battery is discharged to the target DOD. The battery is cycled within the DOD range one or more times, wherein the cycling comprises a charge pulse and a discharge pulse at the selected current levels. A reference performance test (RPT) is performed on the battery, wherein the RPT comprises a static capacity test and a dynamic power test. The cycling and RPT testing are repeated until an end of test condition is detected.

  • Patent number: 8301374
    Abstract: A landmark-based method of estimating the position of an AGV (autonomous ground vehicle) or conventional vehicle, which has an onboard database of landmarks and their locations coordinates. During travel, the AGV looks for and identifies landmarks. It navigates according to position estimations that are based on measured yaw rate and speed. When a landmark s encountered and recognized, its true location coordinates are looked up from the database. These true coordinates are then used to enhance position estimation accuracy between landmarks.

  • Patent number: 8180513
    Abstract: The present disclosure relates to a reference yaw rate generator for an autonomous ground vehicle control system. The reference yaw rate generator is configured to generate a reference yaw rate (rr) based on an actual latitudinal position (Y), a desired latitudinal position (Yd), an actual longitudinal position (X), a desired longitudinal position (Xd) and an actual heading (?) of the autonomous ground vehicle.

  • Patent number: 6754603
    Abstract: The virtual vehicle transmission test cell includes an electric motor which simulates a fuel driven engine, an output motor which simulates the load a transmission experiences in a vehicle, and an environmental element which controls the ambient environment of the transmission and the temperature of the transmission oil within the transmission. The virtual vehicle transmission test cell reduces in-vehicle testing, reduces testing with fuel-driven test cells, and enables development of a transmission design before a corresponding engine is completed and built for testing.
