    摘要： A data multiplexer for multiplexing at least digital moving picture data and pattern data (character data) comprises a packetizing means for forming the digital moving picture data and the pattern data into PES packets of a predetermined format based on the MPEG-2 standard, each packet consisting of a header and an actual data region; an adding means for adding, to the header of each packet, a flag to identify the moving picture data and the pattern data; and a means for multiplexing the packets. An ID flag recorded in the header of each PES packet serves to identify a video packet, an audio packet or a pattern data packet. Each packet of the pattern data and the digital moving picture data includes a time stamp indicative of decode or display timing. In this data multiplexer, the pattern data (character data) on any horizontal scanning line can be multiplexed and recorded with the digital moving picture data.

    摘要： A traction control device operates to determine the speed of each of the left and right drive wheels of a vehicle, determine the speed of each of the left and right passive wheels of the vehicle, calculate the actual slip rate of the drive wheels of the vehicle directly based on the measurements of the speeds for the drive and passive wheels, establish a target slip rate and control the driving condition of the vehicle by making the actual slip rate equal the target slip rate. The actual slip rate is matched to the target slip rate by controlling engine output and braking power. The step of controlling the driving condition of the vehicle by controlling the engine output and the braking power is carried out according to the time differential of the difference between the actual slip rate and the target slip rate at least until the actual slip rate matches the target slip rate for the first time. After the actual slip rate has matched the target slip rate at least once, the step of controlling is carried out according to the proportion of the difference between the actual and the target slip rates.

    摘要： A traction control system for a motor vehicle having driving wheels and driven wheels includes a device for detecting the speed of each of the driving wheels of the vehicle, a device for detecting the speed of each of the driven wheels of the vehicle, a device for calculating a slip value of the driving wheels based on the detected speeds of the driving and driven wheels, a traction control device for controlling the driving wheel so that the slip value of each driving wheel is equal to a predetermined desired slip value when the slip value of each driving wheel is greater than the predetermined desired slip value, and a device for estimating a friction coefficient of a road surface which is employed when the predetermined desired slip value is determined. The estimating device updates the friction coefficient of the road surface previously estimated with the friction coefficient of the road surface newly estimated when the slip value of the driving wheel is located in a predetermined region.
