摘要： When the steered wheels are driven, there is a problem of the torque steering that the steering is disturbed by the difference in the driving forces between a pair of left and right steered wheels. Before such a problem, there is a problem that, since the vehicle is apt to run straight ahead more strongly as the driving force increases even when a uniform driving torque is given to a pair of steered wheels, a larger force is required to steer the vehicle leftward or rightward by overcoming such a tendency of running straight ahead. In view of the above, the steering assist force is increased according to an increase of the driving torque of the steered wheels in a manner of harmonizing the steering assist force to the magnitude of the steering resistance due to the driving torque of the steered wheels, so as to improve the steering feeling.
摘要翻译：当转向轮被驱动时，存在扭矩转向的问题，转向被一对左右转向轮之间的驱动力的差异所扰乱。在这样的问题之前，存在这样的问题：由于即使在对一对转向轮施加均匀的驱动转矩时，由于驱动力增大，车辆也容易向前挺直，所以需要较大的力来转向车辆向左或向右通过克服这种向前跑的倾向。鉴于上述，根据转向轮的驱动转矩的增加，转向辅助力以与转向轮的驱动转矩相应的转向辅助力与转向阻力的大小相协调的方式增加，以提高转向感。

摘要： A vehicular brake control apparatus performs braking force limiting control for limiting, if the vehicle is in a predetermined driving state, braking forces applied to rear wheels of the vehicle in comparison with the braking forces applied to the front wheels. If it is judged during the braking force limiting control that the amount of braking operation by the driver has increased, the apparatus increases the braking forces applied to the rear wheels.

摘要： The present invention is directed to an apparatus for determining a state of braking operation of a vehicle. Wheel speed sensors are provided for detecting wheel speeds of a front wheel and a rear wheel. A wheel speed difference is calculated between the wheel speed of the front wheel and the wheel speed of the rear wheel detected by the wheel speed sensors. A braking operation detection device is provided for detecting an operation of a brake pedal. Based upon the calculated wheel speed difference and the operation of the brake pedal detected by the braking operation detection device, it is determined whether the brake pedal was rapidly depressed. In accordance with this result, and in response to the wheel speeds detected by the wheel speed sensors, the braking force applied to the front wheel can be adjusted in a predetermined relationship with the braking force applied to the rear wheel.

摘要： A new and novel device for controlling a steering characteristic of a vehicle such as automobile so as to enhance an effect of suppressing a change in a behavior of the vehicle body due to a difference between driving and braking forces on the left and right wheels is characterized in that the device makes an amount of controlling the steering characteristic smaller as an index indicating an amount of a shift of vertical loads between the left and right wheels is increased. The steering characteristic is modified through controlling steering assist torque or a steering angle of the steered wheels. The steering assist by the steering control device is fully effective when the vehicle is running on a straight road having surfaces of different frictional coefficients while less effective on a curved road having a uniform frictional surface, preventing undesirable and unexpected modification of the steering characteristic during turning of the vehicle.

摘要： A novel control device for a vehicle power steering apparatus or system is improved for providing preferable steering convergnecy even under the execution of VSC, while ensuring the steering smoothness under normal running conditions. In the control device, the target value of total modification torque to be added to steering torque through an power steering apparatus, is calculated based upon steering assist torque, calculated based upon at least steering torque; steering converging torque, based upon a steering velocity; and behavioral deterioration-suppressing torque for suppressing unwanted steering motions which would cause further deterioration of a vehicle behavior under oversteered or understeered conditions. In this calculation, when a predetermined condition is satisfied, the degree of contribution of the target value of the behavioral deterioration-suppressing torque to the target value of the total modification torque is rendered higher than the degree of contribution of the target value of the steering converging torque to the target value of the total modification torque.
