  • Patent number: 11008930
    Abstract: When an incremental amount of a steering angle exceeds a reference incremental amount, an ECU 60 executes vehicle attitude control of reducing an output torque of an engine, and, in a given operating range, drives a spark plug 16 to allow an air-fuel mixture to be self-ignited at a given timing, thereby executing SPCCI combustion. When there is a request for an additional deceleration from the vehicle attitude control (#12: YES) and the SPCCI combustion is performed (#13: YES), the ECU 60 prohibits ignition retardation and performs torque reduction for the vehicle attitude control, by fuel amount reduction control of reducing the amount of fuel to be supplied into a cylinder 2 (#14). On the other hand, when the SPCCI combustion is not performed (NO in #13), the ECU 60 performs the ignition retardation to attain the torque reduction for the vehicle attitude control (#15).

  • Patent number: 10589732
    Abstract: A device for controlling current for charging/discharging a battery with a high accuracy includes a time-point setting unit which calculates a voltage difference by subtracting a calculated open-circuit voltage from a measured closed-circuit voltage, and sets first and second time points, at which an absolute value of the voltage difference becomes equal to or less than a predetermined value and an absolute value of a difference in the open-circuit voltage becomes equal to or less than a predetermined value. The control device further includes a current correction amount calculation unit to obtain the current integral amount, calculate the current error in a detection signal and set the current error as the current correction amount on the basis of the current integral amount and the time from the first time point to the second time point. The current correction unit corrects the detection signal using the current correction amount.

  • Patent number: 10557424
    Abstract: Methods and systems are provided for controlling the operation of an air charging system of an internal combustion engine. A plurality of actuators include an electric motor of an air compressor. Output parameters of the air charging system are monitored by a plurality of sensors. An error between each one of the output parameters and a target value thereof is calculated by a processor. The calculated errors are applied to linear controllers that yield virtual inputs. Input parameters for the air charging system are calculated using the virtual inputs. The input parameters affect all of the output parameters. The input parameters are calculated with a non-linear mathematical model of the air charging system, configured such that each one of the virtual inputs is in a linear relation with only one of the output parameters. The actuators are operated using the input parameters.

  • Patent number: 10539499
    Abstract: A method for detecting a fault in a robot joint includes the steps of: performing a first torque measurement at the robot joint to thereby obtain a first set of torque values; calculating a first distribution characteristic reflecting a distribution of the first set of torque values; performing a second torque measurement at the robot joint to thereby obtain a second set of torque values; calculating a second distribution characteristic reflecting a distribution of the second set of torque values; and comparing the first and the second distribution characteristics to determine whether a fault is present or not. A difference in the distributions of torque measurements is a robust fault indicator that makes use of the repetitive behavior of the system.

The control system includes a control module that dynamically computes a first power value (PC) to be generated by a compressor based on an estimation model of the compressor. The control system further includes a power term estimator module that dynamically computes a second power value (PU) based on a measured compressor pressure ratio (?cmeas) of the compressor. The control module further computes an amount of power to be generated by an engine (Ptdes) by adding the first power value and the second power value. The control module further adjusts an actuator position to generate the amount of power to be generated.

The heating control is a control for bringing the internal combustion engine into a combustion state and heating by the heater core. The electronic control unit is configured not to execute the heating control but to execute the regeneration cut control when the heating control is requested and the regeneration cut control is requested.

  • Patent number: 10473051
    Abstract: Race car settings (e.g., Formula 1 engine mix settings) are developed for particular racing goals such as faster lap time, better acceleration, less vehicle wear, etc., using pattern templates that are derived from historical racing scenarios. The historical scenarios provide data on racing settings, racing results, and racing conditions such as squad information, equipment information, and environmental information. A cognitive (deep question answering) system can select an initial pattern template based on current racing conditions, and present suggested vehicle settings to the user (driver) using the initial pattern template. The driver can select from different candidate values for various factors, which may lead to the presentation of additional suggestions or the use of additional pattern templates. The final settings map is created based on the employed pattern templates and the driver selections.
