  • Patent number: 11529936
    Abstract: A method for checking the plausibility of a lateral acceleration and further input variables of a transmission shifting program includes measuring, over a defined route section, a lateral acceleration signal, calculating a mean value of the measured lateral acceleration signal, and calculating, based on the further input variables, a plurality of n?2 different lateral acceleration sensor reference variables. The different lateral acceleration sensor reference variables are calculated by a lateral acceleration reference model for the defined route section. The method further includes determining, for each respective lateral acceleration sensor reference variable, a respective mean value of a calculated lateral acceleration, determining deviations of the mean value of the measured lateral acceleration and the mean values of the calculated lateral accelerations, and evaluating, based on a magnitude of the deviations, whether or not the measured lateral acceleration and the further input variables are plausible.

  • Patent number: 11447142
    Abstract: Aspects of the disclosure provide for controlling an autonomous vehicle. For instance, a first probability distribution may be generated for the vehicle at a first future point in time using a generative model for predicting expected behaviors of objects and a set of characteristics for the vehicle at an initial time expected to be perceived by an observer. Planning system software of the vehicle may be used to generate a trajectory for the vehicle to follow. A second probability distribution may be generated for a second future point in time using the generative model based on the trajectory and a set of characteristics for the vehicle at the first future point expected to be perceived by the observer. A surprise assessment may be generated by comparing the first probability distribution to the second probability distribution. The vehicle may be controlled based on the surprise assessment.

  • Patent number: 11371219
    Abstract: A system may determine that an upcoming pass is a final pass associated with loading a machine. The system may compute, based on determining that the upcoming pass is the final pass, a trigger time associated with causing a trigger signal to be transmitted. The trigger time may be computed based on a final pass completion time that identifies a time at which the final pass is expected to be completed. The trigger time may be prior to the final pass completion time. The system may cause the trigger signal to be transmitted at the trigger time. The system may cause, based on a receipt of the trigger signal, a transition of the machine from an idle state to a ready state to be initiated. The transition from the idle state to the ready state may be caused to be initiated prior to a time at which the final pass, associated with loading the machine, is completed.

  • Patent number: 11332118
    Abstract: Provided is an electric motor vehicle including a secondary battery, an electric motor, and a control device that controls an input to and an output from the secondary battery. Using an SOC of the secondary battery, the control device calculates a first OCV that is an OCV based on an assumption of absence of a change in voltage due to polarization. Using a voltage and a current of the secondary battery, the control device calculates a second OCV that is an OCV including a change in voltage due to polarization. When a voltage difference between the first OCV and the second OCV resulting from discharging of the secondary battery is large, the control device augments a limit value of electricity input into the secondary battery to be higher than a limit value when the voltage difference is small.
