Moreover, the unit activates, as a second state, the motors in a power running state, thereby generating motor driving torques, and causes the mechanisms to generate friction braking forces.

20150032333 | VEHICLE BEHAVIOR CONTROL APPARATUS - In order to control a behavior generated on a body as a result of a travel of a vehicle, an electronic control unit controls rotation of each of in-wheel motors, thereby generating a predetermined braking force or driving force approximately the same in magnitude on each wheel. Meanwhile, the electronic control unit uses respective pipelines and a direction control circuit depending on the behavior generated on the body to connect fluid pressure cylinders on a fluid pressure supplying side and fluid pressure cylinders on a fluid pressure supplied side to each other for communication. As a result, the fluid pressure cylinders convert vertical forces of the body acting as component forces of a predetermined braking/driving force into hydraulic pressures and supply the fluid pressure cylinders with the hydraulic pressures, and the fluid pressure cylinders convert the supplied hydraulic pressures into vertical forces, thereby exerting the vertical forces on the body. | 01-29-2015 |
20150105978 | VEHICLE BRAKING/DRIVING FORCE CONTROL APPARATUS - When an ECU carries out vehicle yaw motion control on such a vehicle that a conversion rate of converting the braking/driving force into a vertical force is larger on rear wheels than on front wheels, a driver-requested braking/driving force is distributed to the four wheels so that a distribution ratio is larger for the rear wheels than for the front wheels. Thus, when roll control necessary as a result of the vehicle yaw motion control is carried out, a target braking/driving force of a turning outer wheel for which the largest control driving force is required becomes hard to reach a driving limit. From the foregoing, when vehicle motion control is carried out with use of a braking/driving force of each wheel, each wheel is prevented from reaching a driving force limit as much as possible. | 04-16-2015 |
20150158493 | VEHICLE BRAKING/DRIVING FORCE CONTROL APPARATUS - When a braking/driving force on each wheel is used for vehicle motion control, in order to reduce a noise generated by a zero cross of a motor torque, provided is a distribution setting part, which is to be applied to a vehicle configured so that a conversion rate of converting a braking/driving force on the wheel into a force in a vertical direction of a body by a suspension is different between a front wheel side and a rear wheel side. The distribution setting part sets distributions of a driver-requested driving force to front/rear wheels so as to be larger to the wheels coupled to the suspensions smaller in conversion rate than to the wheels coupled to the suspensions larger in conversion rate. As a result, a zero cross of a motor torque is restrained, resulting in a reduction in generation of a noise caused by a backlash of speed reduction gears. | 06-11-2015 |
