Title: Radio packet communication equipment
Inventor: IIZUKA MASATAKA
IPC: H04W56/00
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To improve the transmission efficiency of a broadcast packet by re-transmitting the broadcast packet by orthogonal frequency division multiplex at a predetermined transmission timing based on the destination information of a received packet by a relay radio station. SOLUTION: When an OFDM reception processing part 51 receives the broadcast packet transmitted by the orthogonal frequency division multiplex(OFDM), a packet-to-present-station judgement part 52 judges that it is the packet to the other station and transfers it to a relay packet processing part 54. The relay packet processing part 54 generates the broadcast packet for relay and sends it to an OFDM transmission processing part 55. At the time of receiving reception completion informing signals S1, a transmission timing control part 53 counts the transmission timing and sends transmission start informing signals S2 to the OFDM transmission processing part 55. The transmission timing is set to a minimum time interval required for a processing from the reception of a radio LAN standard to the start of transmission.

Abstract: PURPOSE:To provide a vehicle slip controller which can enhance the turning performance of a vehicle on low mu roads without deteriorating acceleration of the vehicle when the vehicle runs on middle and high mu roads and when the vehicle goes straight on low mu roads. CONSTITUTION:A vehicle is recognized as making a turn on a low mu road and speed change is stopped if the following conditions are satisfied: vehicle body velocity VF is above a predetermined value V1 at which the problem of driving wheels slipping arises (step S1); the steering angle theta is above a predetermined value thetaH1 (step S2); traction control is being performed (step S3); and vehicle body acceleration AF is below a predetermined value A1 (step S4). Thereby lowering of cornering forces due to slipping of the driving wheels caused by careless speed changes can be prevented, and in other running conditions regulation of speed changes is not performed so that acceleration can be maintained.
