    • PROBLEM TO BE SOLVED: To provide a method for regulating the sliding speed of a vehicle when a slip occurs on an ascent slope. SOLUTION: The method for regulating the vehicle includes a step of setting a brake torque Tb * so that the slip down speed of the vehicle becomes a predetermined vehicle speed by multiplying a torque insufficient, in a limited time motor torque Tm * to a balanced torque Tgrad corresponding to a road surface gradient guided from the relationship between an acceleration of the vehicle, and a torque output to the drive shaft by a ratio (reflecting ratio β) responding to a vehicle speed V of a reverse direction (S118) when a slip occurs due to idling of the drive wheels on the ascent slope for limiting the motor torque Tm * required for the drive shaft connected to the drive wheel; and a step of operating the brake torque Tb * by a hydraulic brake mounted on a non-drive wheel different from the drive wheel (S130). As a result, the speed of the vehicle slipping down on a gradient by the limit of the motor torque Tm * can be regulated. COPYRIGHT: (C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a travel support apparatus that can control a vehicle travel more exquisitely even if the distance of an obstacle and the vehicle becomes a close distance at reverse of the vehicle.SOLUTION: A travel support apparatus 10 has a sonar 12 that detects an obstacle Oa behind the vehicle 11, and includes a PCS ECU 20 that controls travel of the vehicle 11 to prevent contact with the obstacle Oa when reversing. The PCS ECU 20, when the obstacle Oa approaching an undetectable range by the sonar 12, controls travel of the vehicle 11 based on the distance to the obstacle Oa estimated based on the traveling distance of the vehicle 11 from a position which has been detectable of the obstacle Oa by the sonar 12. The distance with the obstacle Oa is presumed even in a situation that the obstacle Oa approaches too much and enters in a range undetectable by the sonar 12 and the obstacle Oa has been lost, the contact with the obstacle Oa can be prevented based on the presumed distance.
    • 要解决的问题:为了提供一种行驶辅助装置,即使在障碍物和车辆的距离在车辆的相反方向处于接近距离的情况下,也能够更精确地控制车辆行驶。 行驶支持装置10具有检测车辆11后方的障碍物Oa的声纳12,并且包括控制车辆11的行驶以防止与倒车时的障碍物Oa接触的PCS ECU 20。 当通过声纳12接近不可检测范围的障碍物Oa时,PCS ECU 20基于与基于车辆11的行驶距离从已经检测到的车辆11的行驶距离估计出的距离到障碍物Oa来控制车辆11的行驶 障碍物Oa的距离即使在障碍物Oa接近太多并且进入不能被声纳12检测到的范围内并且障碍物Oa已经丢失,与障碍物接触的情况下也被推定。 可以根据推定的距离来防止Oa。 版权所有(C)2012,JPO&INPIT
