| 20120247424 | INTERNAL COMBUSTION ENGINE CONTROLLER FOR SETTING IDLE SPEED AND VEHICLE MOUNTING THE SAME - An ECU for controlling an engine counts an unused time TIM of engine in a low-temperature environment. If the unused time TIM is shorter than a predetermined reference value, the ECU sets idle speed immediately after start of operation of the engine to a first idle speed, and if the unused time TIM is longer than the reference value, sets the idle speed to a second idle speed higher than the first idle speed. If duration of the second idle speed exceeds a reference period determined by state of driving of the vehicle, the ECU sets the idle speed to be lower than the second idle speed. In this manner, increased vibration in idling operation in a low-temperature environment can be prevented. | 10-04-2012 |
| 20120310441 | VEHICLE OPERATING STATE DISPLAY DEVICE - An operating state display device for a vehicle includes a display portion that displays an energy transmission state of the vehicle. A display similar to what is shown when no energy is being transmitted to the axle is shown, regardless of the energy transmission state, when two conditions that the vehicle is stopped and that a brake operation is being performed are satisfied. | 12-06-2012 |
| 20120323422 | CONTROL APPARATUS FOR HYBRID VEHICLE - A control apparatus for a hybrid vehicle that includes a battery includes a controller that controls a charge amount of the battery. The controller limits the charge amount of the battery at a time of low vehicle speed even when a state of charge of the battery has fallen. The controller relaxes a limitation on the charge amount when a power driving mode, in which higher priority is given to responsiveness of a driving force than at a time of a normal driving mode, is selected as a driving mode of the hybrid vehicle. | 12-20-2012 |
| 20130060440 | VEHICLE BRAKING SYSTEM - A vehicle braking system includes (a) a rotary machine that functions at least as an electricity generator and that is capable of generating braking torque based on regenerative torque, (b) a first braking control apparatus that electrically controls the braking torque of a mechanical brake that is provided for a wheel, and (c) a second braking control apparatus that replaces one of the braking torque provided by the rotary machine and the braking torque provided by the mechanical brake with another one of the braking torque provided by the rotary machine and the braking torque provided by the mechanical brake while maintaining a target braking torque, the second braking control apparatus correcting the braking torque provided by the rotary machine so that the deviation lessens, if the braking torque of a vehicle has deviation from the target braking torque at time of replacement transition. | 03-07-2013 |
| 20130090798 | CONTROL DEVICE OF HYBRID VEHICLE - Provided is a control device of a hybrid vehicle having an engine and a motor as driving force sources for running and configured to inform a driver that the vehicle is in motor running where the vehicle runs using only the motor as the driving force source for running, by turning on an indicator lamp, from the start of an engine rotation stop process preceding the motor running, wherein in a predetermined low vehicle speed range previously defined as a vehicle speed range where the driver is sensitive to a vehicle vibration due to passage of an engine speed through an engine resonance band, turning on of the indicator lamp is delayed from the start of the engine rotation stop process. | 04-11-2013 |
| 20140014065 | CONTROL DEVICE FOR INTERNAL COMBUSTION ENIGNE AND VEHICLE INCORPORATING CONTROL DEVICE - An ECU for controlling an engine counts the continued period of stopping the engine in a low-temperature environment. The ECU sets the idle rotational speed at a first idle rotational speed when the stopped period is below a predetermined threshold value, and at a second idle rotational speed higher than the first idle rotational speed when the stopped period exceeds the reference value. Accordingly, resonance at the driving force transmission system during idle operation can be prevented even in the case where a mount employed for attaching the engine to the vehicle is hardened as a result of undergoing a low-temperature environment for a long period of time, and the resonant rotational speed of the driving force transmission system including the engine varies. | 01-16-2014 |
| 20140129068 | CONTROL DEVICE FOR VEHICLE - A hybrid vehicle outputs creep torque by output torque of a second MG. A creep control unit controls creep torque when an accelerator pedal is not operated. The creep control unit controls a creep cut amount defined by a decrement of creep torque when the brake pedal is operated relative to creep torque when the brake pedal is not operated such that the creep cut amount when reverse running is selected is smaller than the creep cut amount when forward running is selected. | 05-08-2014 |
| 20140141934 | CONTROL APPARATUS AND CONTROL METHOD FOR VEHICLE - An ECU selects, in accordance with operation by a driver, either one of a manual shift mode in which a shift range can be manually changed through the operation by the driver and an engine rotation speed is controlled in accordance with a selected shift range and an automatic shift mode in which the engine rotation speed is controlled so as to reduce an amount of fuel consumption as compared with that in the manual shift mode. The driver is recommended to make a change from the manual shift mode to the automatic shift mode when the manual shift mode is selected. | 05-22-2014 |
| 20140236441 | GEAR SHIFT INDICATION DEVICE - In a hybrid vehicle provided with a continuously variable electric transmission mechanism capable of sequential shift mode, a minimum engine rotational speed is specified for each gear specified in the sequential shift mode so that the lower the gear, the greater the minimum engine rotational speed. When the engine rotational speed has decreased to the minimum rotational speed while driving in the sequential shift mode, an upshift lamp of a gear shift indication device is turned on to prompt the driver to manually shift to a higher gear. As the driver shifts to a higher gear in response to the prompt, the minimum engine rotational speed is specified to a lower value. That allows for further decrease of the engine rotational speed and improves fuel consumption rate. | 08-21-2014 |
| 20140257653 | GEAR-SHIFT INSTRUCTION DEVICE FOR HYBRID VEHICLE - In a gear-shift instruction device for the hybrid vehicle that includes an engine that can output power for running, an electric motor (such as a motor-generator and a motor) that can output power for running, a power transmission system that transmits power to a drive wheel and can manually select a gear shift position, and a gear-shift instruction unit that prompts a change of the gear shift position to a driver, modes of the guide for gear shift are different between during electric motor running (EV running) and during hybrid running (HV running) for a same accelerator depression amount and vehicle speed in a state that allows manual gear shift operation (manual gear shift mode). This ensures the compatibility between: improvement in energy efficiency and fuel consumption by the gear shift instruction; and reduction in burden of the driver due to gear shifting based on the gear shift instruction. | 09-11-2014 |
