20080249690 | Vehicle control system - A vehicle control system controls vibrations that are generated at a plurality of portions of a vehicle. An engine/drive system ECU and a brake system ECU store the same vehicle vibration model that is separated into a vehicle body vibration model, a chassis vibration model and a tire vibration model, respectively. The engine/drive system ECU controls the suppression of the vehicle body vibrations that are estimated from the vehicle vibration model and the brake system ECU controls the suppression of the chassis vibrations and the tire vibrations. Accordingly, it is easy to execute control for suppressing the respective vibrations. | 10-09-2008 |

20090071736 | Vehicle control system and method - A vehicle control system calculates driver-required wheel torque, correction wheel torque to stabilize vehicle motion, required output shaft torque, alternator base torque, target engine torque and alternator torque to realize the output shaft torque. The required output shaft torque is required to realize vehicle motion, and the alternator base torque is required to maintain amounts of electric power in batteries. In order to realize the torque including wide band frequency torque, a torque division unit divides the sum of the torque into each torque actuator response frequency torque. Therefore, the target alternator torque is calculated by the alternator base torque to maintain electric power in batteries and high frequency band torque required by vehicle motion control. | 03-19-2009 |
20090099731 | Electric power steering system - A control unit estimates reverse transfer torque transferred from tires to a steering wheel and calculates an assist gain based on the reverse transfer torque. The control unit calculates basic assist torque demand by multiplying torsion torque detected by a torque sensor by the assist gain. The control unit further calculates assist torque command by adding compensation for stabilization. Since the assist gain is determined based on the reverse transfer torque, actual assist torque is generated in accordance with the force transferred from the road surface. Thus, a driver can operate the steering wheel while feeling the force from the road surface. | 04-16-2009 |
