Systems and methods for reducing inertial forces of a reciprocating piston internal combustion engine are described. The systems and methods may provide for counterweights in a form of pistons in cylinders that are moved via electromagnets. The counterweights may be moved at a frequency that corresponds to engine speed via an alternating current.

A vehicle control apparatus is applied to a vehicle including an engine as traveling drive source and a clutch device in a power transmission path connected to an output shaft of the engine. The vehicle control apparatus causes the vehicle to be in a coasting state by reducing power transmitted in the path by clutch device operation upon satisfaction of a predetermined implementation condition, and cancels coasting state by clutch device operation upon satisfaction of a predetermined coasting cancellation condition including at least an accelerator condition during coasting. The vehicle control apparatus includes a travel determination section determining coasting state of the vehicle, and a clutch control section performing half-clutch control during coasting at least at one of at the beginning of coasting and immediately before coasting is cancelled, the half-clutch control setting a degree of clutch device engagement to an intermediate degree.

The power train of an electric vehicle includes an electric motor and a gearbox coupling the electric motor to a drive wheel. A controller may be configured to initiate a gear shift in the gearbox, and activate one or both of (a) a torque jog in electric motor, or (b) a burst of a pressurized fluid in an actuator to assist with the gear shift.

An electrically driven vehicle includes an electric motor, a power storage device, an air conditioner, a heat exchanger of a refrigerating cycle, a heater and a controller, the air conditioner includes an internal air suction port and the foot blowout port installed at a position close to the internal air suction port, and, when a remaining capacity of the power storage device exceeds a predetermined value, the controller operates the refrigerating cycle and the heater, and further, is switched to an internal air circulation in which conditioning air blown out of the foot blowout port is suctioned from the internal air suction port.

The invention is a system for automatically adjusting drive modes based on weight. The system includes a weight determination system, a data input device configured to receive input data, and a processing device. The processing devices includes a processor and non-volatile memory. The processor is configured to receive weight data from the weight determination system, receive the input data from the data input device, and receive a user input. The processor is also configured to determine at least one drive mode setting based on the weight data, the input data and the user input, send the drive mode setting data to a vehicle control system, and communicate the drive mode setting to a user.

An apparatus for controlling energy regeneration variably capable of performing a variable control based on a deceleration event discrimination using a map information input as well as a driver's operation may include a controller configured to change a preset energy regeneration stage variably to a corresponding regenerative braking control by sensing an event for an energy regeneration stage and perform the corresponding regenerative braking control, and a generator configured to generate power according to the regenerative braking control.

A computer, including a processor and a memory, the memory including instructions to be executed by the processor to generate a first color image of a road environment, determine one or more value decompositions of one or more of the red, green, and blue channels of the first color image, obtain one or more modified singular value decompositions by modifying respective ones of the singular value decompositions by a non-linear equation and reconstruct a second color image based on the modified one or more singular value decompositions. The instructions can include further instructions to train a deep neural network based on the second color image and operate a vehicle based on the deep neural network.

A system for dynamically maintaining a vehicle speed during a change in road grade comprises a first sensor configured to detect a depression amount of an accelerator pedal and a second sensor configured to monitor the vehicle speed. The system further comprises a vehicle speed control module configured to: receive an indication that the accelerator pedal is depressed; receive an indication of the vehicle speed; determine that the pedal has been depressed within a threshold amount for a threshold time period; determine that the vehicle speed has been maintained within a threshold for the threshold time period; determine whether the change in the road grade is less than a threshold grade; and, based on a determination that the change in the road grade is less than the threshold, automatically adjust a load on a power source of the vehicle to maintain the vehicle speed during the change in road grade.

A multi-layer control mechanism for optimizing performance metrics of a hybrid electric vehicle (e.g., fuel efficiency, drivability, NVH). A first layer generates a policy that defines target engine & motor operating settings for each of a plurality of possible driver demand inputs based on a predicted driver demand profile for a long-horizon period of time. A second layer determines a predicted short-horizon driver demandbased, for example, on historical driver data and one or more environmental sensor inputsand applies a corrective pre-adjustment to the operating settings of the vehicle in response to determining that a pre-adjustment is required in order to apply the target operating settings for the predicted driver demand. A third layer determines constraints to the operating settings required to comply with the additional performance parameters and limits the operating settings applied to the engine and motor(s) to feasible operating settings defined by the constraints.

A vehicle control device has a processor configured to estimate whether or not a driver is attempting to begin vehicle travel after a vehicle has been activated, based on a photographed image of an area near a driving seat, and to control an electrical oil pump to supply a second hydraulic pressure that is lower than a first hydraulic pressure which allows operation of a transmission having a frictional engagement element that can be engaged and disengaged by hydraulic pressure, when it has been estimated that the driver is not attempting to begin vehicle travel, or to control the electrical oil pump to supply the first hydraulic pressure to the transmission, when it has been estimated that the driver is attempting to begin vehicle travel.
