摘要： An engine overrun preventing system for a vehicle, in which the overrun of an engine is prevented when the overrun of the engine is detected, by (i) switching a lock-up system provided in a torque convertor OFF to cause a slip, if it is detected that the lock-up system is in its ON state; (ii) shifting a transmission into a speed range which is one grade lower than a presently selected speed range and reducing vehicle speed by engine brake, if it is detected that the lock-up system is in its OFF state and that the transmission is placed in another speed range than a first speed; and (iii) actuating a brake to reduce vehicle speed, if it is detected that the lock-up system is in its OFF state and that the transmission is placed in the first speed and if a detected vehicle speed is equal to a predetermined vehicle speed or more.

摘要： A straight-ahead traveling control system for a bulldozer comprising: (a) a driving mode setting device which can set an automatic blade control mode for dozing operation; (b) a yaw angle detector for detecting the yaw angle of a vehicle body in relation to a target traveling direction for the vehicle body; (c) a blade tilt angle detector for detecting the tilt angle of the blade tilting laterally in relation to the ground; and (d) a blade controller for controlling tilting of the blade based on a first blade tilting amount used for driving the vehicle body straight ahead and a second blade tilting amount used for forming a laterally horizontal earth surface after digging by the blade, the first blade tilting amount being obtained from the yaw angle of the vehicle body detected by the yaw angle detector and the second blade tilting amount being obtained from the tilt angle of the blade detected by the blade tilt angle detector, when the driving mode setting device has set the automatic blade control mode.
