Methods and systems are provided for balancing injector fueling. In one example, a method includes learning portions of a transfer function shape by firing a plurality of injectors at PWs of a set of PWs following a reference injection.

A vehicle control device includes a memory configured to store relationship definition data that defines a relationship between a state of a vehicle and an action variable, which is a variable relating to an operation of electronic equipment in the vehicle, and a processor. The processor is configured to execute acquisition processing of acquiring a detection value of a sensor and driving preference information, operation processing of operating the electronic equipment, reward calculation processing of providing a greater reward when a characteristic of the vehicle satisfies a criterion than when the characteristic of the vehicle does not satisfy the criterion, and update processing of updating the relationship definition data. The processor is configured to, based on update mapping, output the relationship definition data updated to increase an expected return on the reward when the electronic equipment is operated in compliance with the relationship definition data.

A device for controlling driving of a vehicle includes: a detector to acquire driving information, driver information, and surrounding environment information about the vehicle, and a controller to determine whether to activate a safety driving mode based on at least one of the driving information, driver information, and surrounding environment information about the vehicle, and to determine whether to maintain the safety driving mode state based on a vehicle state after the activation of the safety driving mode. Thus, the device may support a safety driving of the vehicle by restricting a speed of the vehicle even when the driver incorrectly operates an accelerator pedal in place of a brake pedal of the vehicle.

A method of controlling an electronically controllable valve of an engine includes receiving, from one or more operation sensors, operation data including sensor data corresponding to a condition of the engine, control inputs indicative of operation of equipment that includes the engine, or a combination thereof. The method includes determining, using a trained valve control model, an operating characteristic of the valve at least partially based on the operation data, and generating a control signal to effect operation of the valve in accordance with the operating characteristic.

This disclosure relates to a method of controlling an engine and more particularly for controlling the transition between operating modes of an internal combustion engine such as between an economy mode and a performance mode. The method comprising the steps of determining a current fuel-air ratio at which the engine is operating and comparing it with a predetermined fuel-air ratio limit. The time duration for which the current fuel air-ratio is below the fuel-air ratio limit is determined and compared with a predetermined waiting time threshold value. A count is triggered, which is based on a difference between the current fuel-air ratio and the fuel-air ratio limit when the engine is operating at a current fuel-air ratio which is below the fuel-air ratio limit and this is compared with an intensity threshold value. The operating mode is shifted from the performance mode to the economy mode when both the time duration and the count exceed the waiting time threshold value and the intensity threshold value respectively. The operating mode is automatically shifted back to the performance mode when the current fuel-air ratio reaches or exceeds the fuel ratio limit. The method alternatively comprises using the air-fuel ratio, instead of the fuel-air ratio, and the switch from performance mode to economy mode only occurs when the current air-fuel is above a predetermined air-fuel limit and it remains above the predetermined air-fuel limit until two other predetermined thresholds have been reached.

Methods, systems, devices and apparatuses for a pedal gain adjustment system. The pedal gain adjustment system includes a user input device configured to receive user input data indicating a desired pedal setting of the vehicle, and an electronic control unit (ECU) coupled to the user input device. The ECU is configured to determine the vehicle is operating in a tow mode, receive the user input data via the user input device, and adjust the pedal gain based on the user input data.

A system of a vehicle includes: a torque request module configured to determine a first engine torque request based on a driver input and to set a second engine torque request to a lesser one of (a) the first engine torque request and (b) an engine torque limit; and a torque limit module configured to, when a vehicle speed is less than a predetermined speed, an accelerator pedal position is greater than a predetermined accelerator pedal position, and a brake torque request for braking of the vehicle is greater than a predetermined torque, set the engine torque limit to less than the first engine torque request.

Methods and systems are provided for controlling imbalance with an exhaust tuning valve. In one example, a method may include adjusting a first exhaust tuning valve in response to combustion torque imbalance in a first and second group of cylinders. Additionally or alternatively, the position of the second exhaust tuning valve may be adjusted in response to an imbalance generated by the same group of cylinders.

A method of controlling an electronically controllable valve of an engine includes receiving, from one or more operation sensors, operation data including sensor data corresponding to a condition of the engine, control inputs indicative of operation of equipment that includes the engine, or a combination thereof. The method includes determining, using a trained valve control model, an operating characteristic of the valve at least partially based on the operation data, and generating a control signal to effect operation of the valve in accordance with the operating characteristic.

An apparatus includes a control circuit. The control circuit is structured to interpret condition data indicative of an external operating condition of a vehicle, determine an operating parameter of the vehicle based on an actuator response of an actuator of the vehicle, compare the operating parameter to an operating parameter threshold where the operating parameter threshold is based on the external operating condition, and remap an actuator response map of the actuator based on the comparison indicating that the operating parameter does not satisfy the operating parameter threshold. The operating parameter includes at least one of a fuel economy value, an emissions value, an acceleration value, a braking value, or a wear value.
