Disclosed are systems and methods for updating of a machine learning model on a vehicle. A data processing system having at least one processor coupled with memory can predict a first value for a characteristic of the vehicle based at least on a model and measure a second value for the characteristic of the vehicle based at least on a sensor of the vehicle. The data processing system can determine a difference between the first value predicted based at least on the model and the second value measured is greater than a tolerance. The data processing system can identify a state of the vehicle associated with the difference between the first value and the second value and provide, in response to the difference determined greater than the tolerance, the state of the vehicle to a server remote from the vehicle to update the model.

An electronic control unit is configured to execute control for executing the external power supply by selecting one of a first power supply mode in which the engine and the generator are actuated to execute the external power supply and a second power supply mode in which the engine and the generator are stopped and the external power supply is executed by using the electric power stored in the power storage device, acquire a current location of the hybrid vehicle, acquire first information indicative of an area where an idle operation of the engine during parking is prohibited, and select the second power supply mode when the current location is in the area indicated by the first information at the time of executing the external power supply.

A method for controlling a mild hybrid vehicle includes: controlling, by a controller, the mild hybrid vehicle to enter into an idle stop and go state in which fuel supply to an engine of the mild hybrid vehicle is interrupted and the engine is stopped when the mild hybrid vehicle is stopped, based on an idle stop and go entry condition; determining, by the controller, whether a road on which the mild hybrid vehicle travels is in a dangerous area based on a distance between the mild hybrid vehicle and a front vehicle that is in front of the mild hybrid vehicle; and releasing, by the controller, the idle stop and go state of the mild hybrid vehicle when it is determined that the road on which the mild hybrid vehicle travels is in the dangerous area.

A computer-implemented method of brake management in an electric or hybrid electric heavy-duty vehicle that has batteries which are configured to absorb energy from regenerative braking is provided. Topographic data containing information about an upcoming downhill slope is obtained. A state of charge target (SOC target) below 100% for said batteries is determined. Based on the obtained topographic data, a total brake power required for maintaining the speed of the heavy-duty vehicle at or below a selected speed limit of the heavy-duty vehicle throughout the travel in the downhill slope is determined. The determined total brake power is in the form of at least one of regenerative braking, auxiliary braking and service braking of the heavy-duty vehicle. The speed of the heavy-duty vehicle when travelling in said downhill slope is controlled by applying said determined total brake power such that the state of charge of the batteries remains below or equal to said SOC target throughout the travel in the downhill slope.

Methods and systems for activating electric vehicles are provided. One method includes, in response to a first command to activate the vehicle, transitioning the vehicle from an inactive state to a wake state where a controller of the vehicle is activated and the vehicle is prevented from being propelled by an electric motor of the vehicle. The method also includes, in response to receiving a second command to activate the vehicle after receiving the first command, transitioning the vehicle from the wake state to a ready state where the vehicle is permitted to be propelled by the electric motor.

Systems and methods for implementing an eco-mode in an electric utility vehicle. One example system includes an electric utility vehicle comprising an electrically driven component. a user actuable input device, and an electronic processor. The electronic processor is configured to receive an input from the user actuable input device. The electronic processor is configured to determine, based on the input. an operational mode for the electric utility vehicle. The electronic processor is configured to operate the electrically driven component based on the operational mode to limit an amount of electrical power consumed by the electrically driven component.

A method and a device for vehicle control are disclosed. The method includes: in response to a driving mode switching instruction, detecting whether an electric quantity of a low-voltage battery of the vehicle is higher than a preset threshold value, the preset threshold value being determined according to an electric quantity value required for the vehicle to park; and when the electric quantity of the low-voltage battery is higher than the preset threshold value, controlling the vehicle to enter a target driving mode corresponding to the driving mode switching instruction.
