20130060444 | VEHICLE CONTROL DEVICE AND VEHICLE CONTROL SYSTEM - A vehicle control system and a vehicle control device can switch control of a supporting device for support a drive of a vehicle between an ordinary travel in which the vehicle travels in a state that a power source for causing the vehicle to travel is operated and an inertia travel in which the vehicle travels in a state that an operation of the power source is stopped. Accordingly, since the vehicle control system and the vehicle control device switch the control of the supporting device between the ordinary travel and the inertia travel, the vehicle control system and the vehicle control device achieve an effect that the vehicle can be caused to appropriately travel by inertia. | 03-07-2013 |
20130237372 | VEHICLE DRIVE SYSTEM - A vehicle drive system is provided with an engine, a manual transmission capable of changing a gear position, a clutch arranged between the engine and the transmission, and a control device that performs drive control of the engine. During an inertia running in which torque transmission between the engine and an axle is blocked, when the clutch is opened and the gear position of the transmission is changed to a forward position, if the gear position after the change is lower than an optimal gear position corresponding to a vehicle speed, the control device executes fuel cutoff for the engine. | 09-12-2013 |
20130304358 | VEHICULAR CONTROL APPARATUS - A vehicular control apparatus performs control of enabling idle operation of an internal combustion engine that generates a motive power applied to a driving wheel of a vehicle if a vehicle speed of the vehicle is lower than a predetermined vehicle speed that is set in advance, and disabling idle operation of the internal combustion engine if the vehicle speed of the vehicle is equal to or higher than the predetermined vehicle speed, when the vehicle is in a state other than an acceleration running state. Accordingly, the vehicular control apparatus achieves an effect of making it possible to suppress the consumption of fuel. | 11-14-2013 |
