A method of generating vehicle control data includes: storing, with a storage device, relationship prescription data; operating, with an execution device, an operable portion of an internal combustion engine; acquiring, with the execution device, a detection value from a sensor that detects the state of the vehicle; calculating, with the execution device, a reward; and updating, with the execution device, the relationship prescription data using update mapping determined in advance, the update mapping using the state of the vehicle based on the detection value, an operation amount used to operate the operable portion, and the reward corresponding to the operation as arguments, and returning the relationship prescription data which have been updated such that an expected profit for the reward calculated when the operable portion is operated in accordance with the relationship prescription data increases.

An apparatus and a method for controlling a hybrid vehicle are provided. The apparatus includes an engine that generates power by combusting fuel and a drive motor that supplements the power from the engine and operates selectively as an electric generator to produce electrical energy. A clutch is disposed between the engine and the drive motor and a battery supplies electrical energy to the drive motor and is charged with the electrical energy produced by the drive motor. Multiple electric superchargers are installed in multiple intake lines through which outside air to be supplied into a combustion chamber of the engine flows. A controller determines an operation mode of the multiple electric superchargers based on required power of a driver and a state of charge (SOC) of the battery and adjusts the power output from the engine and the power output from the drive motor.

A control unit of a vehicle, which is configure to travel in a first traveling mode in which power outputted from an electric motor according to electric power supplied from a generator and an electric storage device is used and in a second traveling mode in which power outputted from an internal combustion engine and the electric motor according to the electric power supplied from the electric storage device is used, includes: a vehicle speed acquisition unit; a driving force acquisition unit configured to acquire a driving force in the first traveling mode according to a vehicle speed and a driving force in the second traveling mode according to the vehicle speed; and a traveling mode control unit configured to drive the vehicle in the traveling mode capable of obtaining a large driving force at the vehicle speed based on a comparison result of the driving forces.

A vehicle control system configured to limit damage to an electric storage device even if a speed of a motor is changed abruptly. The control system is applied to a vehicle comprises: a differential mechanism connected to an engine, the motor, and drive wheels; and a clutch. A controller is configured to: calculate an upper limit power possible to be applied or discharged to/from the electric storage device when a condition to engage the clutch is satisfied; and restrict the electric power to be applied or discharged to/from the electric storage device equal to or less than a maximum allowable power that is less than the upper limit power before the clutch is engaged.

A hybrid vehicle includes an electric generator, a drive motor, a power storage device, a power consuming device, and a controller. The controller is configured to control driving of the power consuming device. The controller is configured to execute power consumption increasing control when a vehicle power balance value is larger than a first threshold while the drive motor operates in a braking-period power generation mode.

A work machine comprises a work unit that performs work on a travel path, an internal combustion engine configured to generate power for driving the work unit, a traveling unit including a front wheel and a rear wheel, an electric motor configured to generate power for driving a first wheel of the front wheel and the rear wheel, and a first clutch for switching between transmission and discontinuation of the power from the internal combustion engine to a second wheel of the front wheel and the rear wheel.

An engine includes an EGR device and a water-cooled heat exchanger. The water-cooled heat exchanger is provided on a downstream side of an EGR gas-introduction portion of an intake passage into which EGR gas is to be introduced and exchanges heat with gas flowing in the intake passage. A control device is programmed to execute condensed water-suppression control that supplies coolant having a temperature higher than the temperature of the gas heat-exchanged in the water-cooled heat exchanger to the water-cooled heat exchanger while a hybrid vehicle is traveling in a state in which the engine is stopped.

Systems and methods for operating a hybrid powertrain or driveline that includes an engine and an integrated starter/generator are described. In one example, engine power is adjusted based on a time averaged transmission input shaft power so that the engine may operate in a power region where its performance is enhanced to support operation in an off-road environment.

A method for detecting combustion irregularities in a combustion engine coupled to an electric engine of a hybrid vehicle having a management unit for determining the respective powers to be supplied by these engines, and for delivering setpoint data dependent on these power distributions, including determining a threshold value corresponding to a percentage of the power supplied by the electric engine, such that values of this percentage less than or equal to the threshold value correspond to operation of the electric engine that is not liable to falsify the results of the combustion irregularity detection diagnostics, and, for the purpose of launching a diagnostic procedure, when the percentage of the power supplied by the electric engine is greater than the threshold value, delivering setpoint data suitable for fixing the value of the power percentage at a setpoint value less than the threshold.
