20090265075 | CONTROL APPARATUS AND CONTROL METHOD FOR VEHICLE - A control apparatus for a vehicle is equipped with a detection portion that detects a required output of an internal combustion engine, an acquisition portion that acquires an ignition timing of the internal combustion engine, a setting portion that sets an operation curve of the internal combustion engine such that the operation curve approaches an optimal fuel consumption operation curve as the acquired ignition timing is retarded with respect to a set ignition timing, a decision portion that decides a target power of the internal combustion engine on the basis of the detected required output and the set operation curve, and a control portion for controlling the internal combustion engine on the basis of the decided target power. | 10-22-2009 |
20100070122 | CONTROL APPARATUS AND METHOD FOR HYBRID VEHICLE - A control apparatus for a hybrid vehicle, which outputs motive power to a drive shaft from an internal combustion engine and motor generators as motive power sources, including: a recirculating gas control portion that performs valve opening control on a recirculation valve so that an amount of recirculating exhaust reaches a control target valve, and that closes the recirculation valve completely when a deceleration request by a driver is detected; a throttle control portion that performs valve closing control on a throttle valve so that the amount of air circulating through an intake pipe decreases at a predetermined speed when the deceleration request issued by the driver is detected; and a braking control portion that controls regenerative braking forces of the motor generators so that at least one of the motor generators absorbs the motive power generated by the engine while valve closing control is executed on the throttle valve. | 03-18-2010 |
20110139096 | VEHICLE CONTROL SYSTEM - A control system for a vehicle that is equipped with an internal combustion engine and a generator driven by the internal combustion engine to generate electric power and that is able to supply an external device with electric power generated by the generator during a stop of the vehicle includes: a detecting unit that detects a coolant temperature of the internal combustion engine; and an efficiency control unit that controls the internal combustion engine so that, during a stop of the vehicle, an operating state of the internal combustion engine approaches an operating state where an efficiency of the internal combustion engine becomes a predetermined efficiency as a difference between the coolant temperature and a predetermined upper limit temperature increases. | 06-16-2011 |
20130041540 | VEHICULAR CONTROL DEVICE - A control device functions as a vehicular control device to control electrically charging/discharging an electrical storage device. The control device includes a fuel calculation unit which calculates an amount of fuel consumed used to electrically charge the electrical storage device, a charge calculation unit which calculates electrical energy charged to the electrical storage device, and an evaluation unit which calculates a numerical evaluation from a result of a calculation done by the fuel calculation unit and that done by the charge calculation unit for an amount of fuel consumed corresponding to an amount of electric power charged in the electrical storage device availably. | 02-14-2013 |
20140163799 | VEHICLE DRIVE CONTROL APPARATUS - A vehicle drive control device in a vehicle has an engine and an electric motor for running, the vehicle running with at least one of the engine and the electric motor for running used as a drive power source for running, the vehicle drive control device rotating the engine remaining in a no-drive state if a vehicle speed is equal to or greater than a predetermined determination vehicle speed during vehicle running with the engine in the no-drive state, the vehicle drive control device making the determination vehicle speed higher when a gradient of a running road surface on which the vehicle is running is larger, the gradient having a positive direction corresponding to descent. | 06-12-2014 |
20140180519 | APPARATUS AND METHOD FOR CONTROLLING VEHICLE - A vehicle incorporates an engine to which an engine-related component is attached, a battery charged with electric power supplied from an external power supply, and an electric motor as a driving source to which electric power is supplied from the battery. An ECU causes at least one of the engine-related component and the battery to be heated, using the electric power supplied from outside while the electric power is being supplied from outside, in accordance with a distance over which the vehicle can run by driving the electric motor alone and a distance to a destination. | 06-26-2014 |
20150066269 | VEHICLE INCLUDING REGENERATION LEVEL SELECTOR FOR MOTOR - A distance sensor detects a distance to an object in front of a vehicle. An ECU executes pre-crash control when the detected distance becomes equal to or smaller than a prescribed value. A regeneration level selector selects a regeneration level of a motor in accordance with driver's operation. A motor makes regenerative braking force at the time of turning off an accelerator larger when the selected regeneration level is high than when the selected regeneration level is low. The ECU makes the prescribed value larger when the selected regeneration level is low than when the selected regeneration level is high. | 03-05-2015 |
