Abstract: A process allocation control method is provided that controls, in a system including an in-vehicle computer mounted in the vehicle and an external computer provided external to the vehicle as nodes communicable with each other, allocation of a process related to driving assistance of the vehicle to the nodes. The process allocation control method includes: estimating an allocation risk of the process being interrupted in cases of allocating the process to either of the nodes, based on at least one of a remaining battery charge of the vehicle or a communication status between the nodes; and determining the node to which the process should be allocated, based on the allocation risk.

Abstract: A method for controlling a hybrid vehicle executes control in which a state of charge of the battery at a time point at which the hybrid vehicle reaches a destination is lower than an upper limit state of charge by executing an EV mode until the hybrid vehicle reaches the destination. During execution of the control, if an estimated value of a lowest temperature of an engine coolant until the hybrid vehicle reaches the destination is equal to or higher than a first threshold value, the EV mode is started when the EV mode is continuable to the destination, and if the estimated value of the lowest temperature is lower than the first threshold value, a section for executing the EV mode is shortened compared to when the estimated value of the lowest temperature is equal to or higher than the first threshold value.

Abstract: An electric-axle device for a commercial vehicle that can minimize the frequency of using a main brake when braking, may include a first clutch device disposed between a motor and a differential casing to transmit or block power, a second clutch device disposed between the differential casing and a disc, an electromagnetic brake applying a braking force to the disc, and that can increase a coasting distance and improve energy efficiency and durability of the motor by disengaging the first clutch device and the second clutch device such that kinetic energy, which is transmitted to the motor from an axle shaft, is blocked as if a neutral gear of a transmission is engaged, when the vehicle coasts.

Abstract: A system and method for actuating a vehicle operation power mode that include receiving sensor data from at least one sensor of a vehicle. The system and method also include determining if at least one vehicle operation requirement is met based on analysis of the sensor data and actuating an electric powered operation mode of the vehicle based on determining that the at least one operation requirement is met. The system and method further include modifying an operation of an electric battery of the vehicle to power the vehicle through the electric battery from being charged by a fuel powered engine of the vehicle based on the actuation of the electric powered operation mode.

Abstract: Vehicle designers are largely walking away from internal-combustion engines to battery and electric motors. Until infrastructure is developed to support total electrification, hybrid-electric vehicles (HEVs) which include both an internal combustion engine and an electric machine are a step toward electrification and higher system fuel efficiency while retaining the expected vehicle range. To obtain even higher system fuel efficiency combustion modes that provide higher efficiency than spark-ignition (SI) operation can be used in HEVs. A problem with such combustion modes is that they cannot be used over as wide an operating range as SI operation and transitions among modes is slow and cumbersome. By having the ICE installed into a HEV be a multi-combustion mode engine and having the EM to coordinate mode switches to be smooth, the high fuel-efficiency of alternative combustion modes can be exploited while providing smooth operation expected by vehicle users.

Abstract: A hybrid vehicle control method for a hybrid vehicle having a drive motor, a battery supplying electric power to the drive motor, and an engine for power generation configured to supply electric power to the battery and the drive motor includes operating the engine at a higher engine rotation speed in an operating state in which a fuel consumption device that contributes to improved fuel consumption performance does not operate than in an operating state in which the fuel consumption device operates.

Abstract: A hybrid vehicle includes a controller. First control is control of an engine and a motor such that the hybrid vehicle travels by switching between a charge depleting mode and a charge sustaining mode. Second control is control of the engine and the motor such that the hybrid vehicle travels in accordance with a travel plan in which the charge depleting mode or the charge sustaining mode is assigned to each travel section of a travel plan route to a destination. The controller controls the engine and the motor such that a state of charge of an electric power storage device becomes higher in the charge sustaining mode in the second control than in the charge sustaining mode in the first control.

Abstract: A system includes a power source and a memory to store an event that is predicted to occur, an action to be performed by the power source to increase efficiency of the power source during the stored event, and a mis-prediction counter indicating a count of mis-predictions. The system further includes an ECU designed to predict that the stored event will occur and to control the power source to take the action when the stored event is predicted to occur. The ECU is further designed to update the mis-prediction counter and to adjust at least one of the stored event that is predicted to occur, the stored action to be performed by the power source, or a prediction horizon of the prediction when the mis-prediction counter reaches or exceeds a threshold quantity of mis-predictions to increase efficiency of the power source during a subsequent prediction of the stored event.

Abstract: Methods and systems are provided for controlling an engine idle-stop based on upcoming traffic and road conditions. In one example, a method may include receiving data including traffic information and road characteristics immediately ahead of a vehicle from one or more remote sources, and adjusting one or more vehicle thresholds based on the received data. A duration of a prospective engine idle-stop may be estimated based on the received data and an engine idle-stop may be initiated based on the duration of the prospective engine idle-stop and the adjusted one or more vehicle threshold.
