    摘要: An improved method of operation for a motor vehicle automatic transmission determines a vehicle speed for purposes of selecting a desired transmission gear at least in part based on the wheel speeds of the vehicle. If the vehicle is being operated in a two-wheel drive mode, the vehicle speed is determined based on an average of the speeds of the un-driven wheels; if the vehicle is being operated in a four-wheel drive mode, the vehicle speed is determined based on the lowest of the four wheel speeds. Optionally, the wheel speeds are only used to determine vehicle speed if the Reverse range of the transmission has been engaged within a specified time interval, and otherwise the vehicle speed is determined based on an output speed of the transmission.

    摘要: The present invention is directed to an apparatus for estimating the peak of a coefficient of friction in a coefficient of friction—slip rate characteristic, wherein a wheel acceleration of each wheel of a vehicle is detected, and a vehicle acceleration of the vehicle is detected. A peak estimation device is provided for estimating the peak of the coefficient of friction, and adapted to determine that the coefficient of friction is the peak when the wheel acceleration is lower than the vehicle acceleration, by more than a predetermined difference. An anti-skid control system for an automotive vehicle may be formed to include the coefficient of friction peak estimation apparatus, and a reference speed setting device for setting a reference speed for initiating a pressure decrease mode on the basis of a wheel speed and a vehicle speed detected when the peak was detected. A pressure control device is disposed between a wheel brake cylinder and a pressure generator, to be controlled in response to at least the result of comparison between the wheel speed and the reference speed.

    摘要: Vehicle motion control devices and methods systematically treat a conditions of each wheel to acquire and maintain the vehicle behavior stability together with anti wheel lock and wheel spin processing, braking forces distribution. Device for controlling a running behavior of a vehicle estimates a road reaction force on each wheel, calculates a yaw moment around a centroid of the vehicle body generated by the road reaction force on each wheel, and controls driving and braking forces on each wheel based upon the yaw moments so as to stabilize a running of the vehicle. Spin and Drift conditions are detected through presently generated yaw moments and critical yaw moments which can be generated by a road reaction force assumed to be maximized. Physical parameters of each wheels, required for detecting and controlling the behavior of the vehicle are estimated with a theoretical tire model.

    摘要: The present invention is directed to a system for detecting a difference in level on a road, wherein an acceleration sensor is provided for detecting an acceleration of a vehicle, and a wheel speed sensor is provided for detecting a wheel speed of at least one wheel of the vehicle. A wheel acceleration is calculated continuously on the basis of the wheel speed detected by the wheel speed sensor. It is determined if a variation of the signal output from the acceleration sensor is greater than a predetermined range. And, it is determined if the calculated wheel acceleration varied in the same direction as that of the variation of the signal output from the acceleration sensor, and then varied in the reverse direction to exceed a predetermined reference value. On the basis of the result of each determination, it is determined if the wheel ran over the difference in level on the road. If the affirmative result is obtained in each determination, the difference in level on the road can be detected.
