Abstract:
An apparatus (100) controls a running state of a hybrid vehicle, wherein the hybrid vehicle is configured to select, as a running mode, an EV running mode and a HV running mode, the hybrid vehicle is configured further to select an intermittent operation mode for repeating acceleration running and coasting by intermittently driving the drive wheels, in the HV running mode. The apparatus switches the EV running mode to the intermittent operation mode according to a comparison result between a power storage amount of the power storing device and a convergence value of the power storage amount in a case where the intermittent operation mode is selected, if the intermittent operation mode is required during steady running by the EV running mode.

Abstract:
A mobility information processing apparatus includes: an allocator that allocates one driving mode-selected from driving modes having different drive forms to each partitioned section, in a route of a moving object; and an estimator that estimates the driving mode selected for each section located apart from a predetermined point in the route and that calculates an estimated amount of energy required for traveling in the section estimated to correspond to the one selected driving mode among the driving modes, wherein the allocator determines whether the one selected driving mode is allocated to each section up to a predetermined point in the route on the basis of an allocated energy amount obtained by subtracting the estimated energy amount calculated by the estimator from a residual energy amount of a power source used in the one selected driving mode for each section up to the predetermined point in the route.
Abstract:
In a vehicle including a plurality of devices (14,16,60,70,72,74) for operating so as to cause a yaw rate of the vehicle to approach a target yaw rate, a target control amount Δγt for the yaw rate for causing a yaw rate γ of the vehicle to approach a target yaw rate γt is calculated (S20 to S60), for each device, a ratio of a change amount of the yaw rate to an energy loss amount caused by an operation is calculated as an efficiency (S80 to S100), the target control amount is sequentially distributed to the plurality of devices (14,16,60,70,72,74) in descending order of the efficiency, to thereby calculate individual target control amounts for the plurality of devices (S110 to S160), and the operations of the respective devices are controlled based on the individual target control amounts (S170).
Abstract:
A drive system for a hybrid vehicle includes a planetary gear unit, a first rotating machine connected to a sun gear of the planetary gear unit, an engine connected to a carrier of the planetary gear unit, a second rotating machine and drive wheels connected to a ring gear of the planetary gear unit, a regulating mechanism that regulates rotation of the carrier, a first running mode in which the vehicle runs using the second rotating machine as a power source, and a second running mode in which the vehicle runs using the first rotating machine and the second rotating machine as power sources while the regulating mechanism regulates rotation of the carrier. The carrier is rotated by the first rotating machine (S40) when the vehicle shifts from the first running mode to the second running mode (S30-Y).

Abstract:
Disclosed is a control device for a vehicle drive device whereby an improvement in vehicle response to accelerator operation by the driver can be achieved, in a vehicle equipped with an internal combustion engine, a supercharger and an automatic transmission. Gear ratio selection control means (80), when the engine (12) is operating in NA condition, if the engine (12) comes to operate in a supercharged condition on change of ratio of the automatic transmission (16) to a first gear ratio (γ1at) in accordance with the gear-change map, performs gear ratio selection control so as to alter the method of selection of the gear ratio (γat) of the automatic transmission (16) in accordance with an increased rate (SPacc) of opening (Acc) of the accelerator. Specifically, in this gear ratio selection control, at the side where the increased rate (SPacc) of opening (Acc) of the accelerator is least, the automatic transmission (16) changes to a first gear ratio (γ1at), but, at the side where the increased rate (SPacc) of degree of opening (Acc) of the accelerator is greatest, the engine (12) is still maintained in the aforementioned NA condition and the automatic transmission (16) is changed to a second gear ratio (γ2at), which is larger than the first gear ratio (γ1at).
