Abstract: A control apparatus for an electrically-operated vehicle that includes an electric motor serving as one of at least one drive power source. The control apparatus includes a vibration-suppression control portion configured to execute a vibration suppression control for causing the electric motor to output a vibration suppression torque by which vibration of the electrically-operated vehicle is to be suppressed. The vibration-suppression control portion is configured to determine whether the electrically-operated vehicle is in a towing state in which the electrically-operated vehicle runs while towing a towed vehicle, or not, and is configured to make a vibration suppression capacity of the vibration suppression control higher when determining that the electrically-operated vehicle is in the towing state, than when determining that the electrically-operated vehicle is not in the towing state.

Abstract: A control apparatus for a hybrid electric vehicle includes: an engine control portion for controlling an operation state of an engine; and a driving-mode control portion for controlling the vehicle so as to realize selected at least one of driving modes. The driving modes include a low-gear all-wheel driving mode and a high-gear all-wheel driving mode. In a case in which the low-gear all-wheel driving mode is selected in the high-gear all-wheel driving mode when the engine is in a stopped state with a vehicle power transmission apparatus being in a non-driving position that disables transmission of a drive power, the engine control portion maintains the stopped state of the engine until completion of switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode, and starts the engine after the completion of the switching from the high-gear all-wheel driving mode to the low-gear all-wheel driving mode.

Abstract: A heat management system disclosed herein is used for an electric vehicle. The heat management system may include an oil cooler, an oil pump, a converter cooler, a first heat exchanger, a second heat exchanger, a first channel, a second channel, a channel valve, a bypass channel, and a controller. The channel valve may be configured to select a first valve position and a second valve position. The bypass channel may be configured to allow the first heat medium to bypass the first heat exchanger and circulate between the oil cooler and the converter cooler when the second valve position is selected. The controller may be configured to control the channel valve such that the channel valve selects the first valve position and activate the oil pump in response to the temperature of the first heat medium in the first channel becoming higher than a predetermined upper limit temperature.

Abstract: A cooling system includes: a first coolant passage; a second coolant passage; a pump; a radiator; a third coolant passage; a connection switching mechanism that switches between a forward flow connection state and a reverse flow connection state; a fourth coolant passage; a fifth coolant passage; and a shutoff valve configured to open/shut off the fifth coolant passage. The radiator is disposed at a location at which coolant flowing from a second end of the first coolant passage into a fourth end of the second coolant passage is not cooled in the reverse flow connection state, and coolant flowing out from the second end of the first coolant passage and the fourth end of the second coolant passage is cooled in the forward flow connection state.

Abstract: An automatic transmission controller is provided, which is capable of reducing occurrence of a shift shock while improving responsiveness of a driving force. An ECU is configured to calculate a target shift time based on an input torque that is input to the automatic transmission when a gear stage is shifted from a current gear stage to a target gear stage spaced two or more stages apart from the current gear stage. The ECU is also configured to: shift the gear stage to an intermediate gear stage between the current gear stage and the target gear stage when the target shift time is not less than a predetermined value; and to shift the gear stage directly to the target gear stage when the target shift time is less than the predetermined value.

Abstract: There is provided a control system of a chemical heat accumulator which enables to facilitate small-sizing of the chemical heat accumulator by carrying out heat release and heat accumulation according to a degree of priority by appropriately selecting a location of carrying out the heat release and heat accumulation on priority basis. A chemical heat accumulator includes a valve mechanism which makes a plurality of reactors communicate separately with a reservoir, and cuts off the plurality of reactors from the reservoir. When both reactors are in a state in which an exothermic reaction between a reaction material and a reaction medium is possible, or in a state in which an endothermic reaction in which the reaction medium is desorbed is possible, a controller which controls an opening of a valve mechanism controls the opening of the valve mechanism such that a flow rate of the reaction medium circulated between the first reactor and the reservoir for which a degree of priority of heat release or heat accumulation is high becomes higher than a flow rate of the reaction medium circulated between the second reactor and the reservoir for which the degree of priority of heat release or heat accumulation is low.
