20140095045 | VEHICLE CONTROL DEVICE - An electronic control unit performs a reduction control for reducing vehicle drive force when the accelerator and the brake are operated simultaneously. The electronic control unit also varies the amount of decrease in the vehicle drive force during the reduction control and conditions under which the reduction control is implemented depending on the order of the accelerator operation and brake operation resulting in the above-noted simultaneous operation. For example, the amount of decrease in the vehicle drive force is less when the brake is operated first in comparison with when the accelerator is operated first. Thus, it is possible to operate the vehicle drive force in accordance with the intention of the driver. | 04-03-2014 |

20130317683 | TRANSMISSION CONTROL DEVICE FOR HYBRID VEHICLE - In a transmission control device for a hybrid vehicle, when an engine torque is equal to or less than a predetermined value during a constant speed traveling, a learning engine rotational speed is set to a rotational speed being higher by +α than the present engine rotational speed. Then, a learning engine torque is calculated that corresponds to the learning engine rotational speed, a learning clutch actuator operation amount is obtained that corresponds to the learning clutch torque, and a clutch actuator is operated based on the learning clutch actuator operation amount. Thereafter, when the engine rotational speed and the engine torque are in stable states, a clutch torque value corresponding to the learning clutch actuator operation amount is compensated by a stable engine torque value. | 11-28-2013 |
