A method of controlling a vehicle drivetrain by an electric motor, in order to synchronize the speed of an internal combustion engine and the speed of gears in the drivetrain, wherein if a speed synchronization error e.sub.sync(t) is controlled to remain within a prespecified region for a specific period of time, the synchronization is finished, and a gear may be engaged.

A method for turning off an internal combustion engine (ICE) where a clutch arrangement has first and second clutches that respectively couple the ICE to first and second input shafts of a transmission. The input shafts are drivingly connected to first and second sets of gears, respectively. The sets of gears are connected to an output shaft of the transmission. The method includes: controlling the ICE in an idling state when the vehicle is in standstill, wherein the clutches are in open positions; engaging the first input shaft with a first pre-selected gear, and engaging the second input shaft with a second pre-selected gear; initiating an engine turning off command; stopping the ICE by at least partly closing the clutches for simultaneously introducing torque transfer to the clutches into a transmission tie-up state for a controlled engine stop, wherein engine inertia of the ICE is captured in the clutches.

A method may include obtaining sensor data that include a plurality of sensor returns from an environment of an autonomous vehicle. A first set of features may be extracted from the sensor data. The first set of features may be processed with a machine learning model to generate, for at least a subset of the plurality of sensor returns, a first output that classifies a respective sensor return as corresponding to an object or non-object and a second output that indicates a property of the object. The sensor returns classified as corresponding to objects may be compared to a plurality of pre-classified objects to generate one or more generic object classifications. The autonomous vehicle may be controlled based at least in part on the one or more generic object classifications.

A display device for displaying at least one of outputs related to traveling of a hybrid vehicle includes a first area that indicates a first output in a first mode and indicates a second output in a second mode, a second area provided side by side with the first area and that indicates a third output in the second mode, and a third area provided in a position adjacent to the second area, and that indicates a range of the first output where a possibility that the internal combustion engine starts is high. The first area has a first display portion that changes according to the first output in the first mode and the second output in the second mode. The second area has a second display portion that changes according to the third output in the second mode.

A vehicle includes a controller configured to switch between a constant speed traveling mode in which a vehicle speed is held constant and an inertial traveling mode in which a prime mover is stopped or in an idling state, and a clutch apparatus configured to connect and disconnect power transmission between the prime mover and an output target, and the controller controls the clutch apparatus and decreases a clutch capacity so as to transit to the inertial traveling mode when detected that the vehicle is traveling on a downhill road during the constant speed traveling mode, and the controller controls the clutch apparatus and increases the clutch capacity so as to transit to the constant speed traveling mode when detected that the vehicle traveling on the downhill road has terminated.

A system to mitigate side-to-side movement of a vehicle induced by passing traffic includes a controller configured to receive vehicle speed information, a traffic sensing system in communication with the controller, a damping system in communication with the controller, and at least one controllable damper in communication with the damping system. The controller determines if the vehicle speed is less than a predetermined minimum vehicle speed threshold, determines if the vehicle is in the proximity of nearby traffic, determines if the nearby traffic is traveling at a speed above a predetermined traffic speed threshold, and commands increased damping at the at least one controllable damper.

A method for controlling wheel slip of a vehicle includes: observing and estimating equivalent inertia information of a driving system in real time based on operation information of the driving system by receiving the operation information of the driving system for driving the vehicle; calculating the compensated amount for compensating a torque command of a driving device from the equivalent inertia information of the driving system observed and estimated by a controller; compensating the torque command of the driving device by using the calculated compensated amount; and performing a control of a torque applied to a driving wheel according to the compensated torque command.

Spark ignition engine operation at higher RPM so as to reduce alcohol requirements in high efficiency alcohol enhanced gasoline engines is disclosed. Control of engine upspeeding (use of a higher ratio of engine RPM to wheel RPM) so as to achieve an alcohol reduction objective while limiting any decrease in efficiency is described. High RPM alcohol enhanced gasoline engine operation in plug-in series hybrid powertrains for heavy duty trucks and other vehicles is also described.

A vehicle learning system includes a first execution device mounted on a vehicle, a second execution device outside the vehicle, and a storage device. The storage device stores mapping data including data, which is learned by machine learning and defines mapping that receives input data based on a detection value of an in-vehicle sensor and outputs an output value. The first execution device and the second execution device execute, in cooperation with each other, an acquisition process of acquiring input data, a calculation process of calculating an output value with the input data as an input of the mapping, and a relationship evaluation process of evaluating a relationship between a predetermined variable different from a variable corresponding to the output value and accuracy of the output value. The first execution device executes at least the acquisition process, and the second execution device executes at least the relationship evaluation process.

A vehicle running mode control method may include detecting, by a mode controller, a mode switching from an electric vehicle mode (EV mode) to a hybrid electric vehicle mode (HEV mode) while a vehicle runs; and performing a continuously variable transmission (CVT) cooperative mode switching control in which a drive motor is connected to an engine by engaging a clutch by operating the CVT.
