Vehicle traveling control device

A vehicle traveling control device in a vehicle including freely rotative wheels;

• front axles and a rear axle for supporting said wheels;
• suspensions for supporting and absorbing shock exerted on said front axles and said rear axle;
• a frame which is supported by said front axles, said rear axle, and said suspensions;
• and a vessel which is mounted on a top portion of said frame;
• said vehicle traveling control device comprising:
• pressure sensors for detecting pressures exerted on respective ones of said suspensions at predetermined cycle times;
• a vehicle speed detector for detecting vehicle speed;
• a controller for determining a stress exerted on at least one of the following:
• said frame, said vessel, said front axles, and said rear axle, based on pressure detection values from respective ones of said pressure sensors at each of said predetermined cycle times, for determining which stress range out of predetermined stress ranges the thus determined stress falls in, for renewing a frequency value corresponding to the thus determined stress range, for obtaining for each stress range a product of a central stress value in a respective one of said stress ranges and a frequency value at the respective central stress value, for calculating a total amount of the thus obtained products in all of the stress ranges as a damage quantity, and for outputting a deceleration instruction when a load multiplying factor, which is calculated based on said damage quantity, is greater than a predetermined allowable value;
• and
• a speed control means for inputting said deceleration instruction, and for controlling at least one of the following:
• engine fuel injection quantity, a transmission, and a braking device, so that a detection value from said vehicle speed detector equals an instructed speed in said deceleration instruction.

• said vehicle traveling control device comprising:
• pressure sensors for detecting pressures exerted on respective ones of said suspensions at predetermined cycle times;
• a loading completion informing means for informing a loader side that loadage weight reaches an allowable loadage weight value when a loading completion signal is inputted;
• and
• a controller for determining a stress exerted on at least one of the following:
• said frame, said vessel, said front axles, and said rear axle, based on pressure detection values from respective ones of said pressure sensors at each of said predetermined cycle times, for determining which stress range out of predetermined stress ranges the thus determined stress falls in, for renewing a frequency value corresponding to the thus determined stress range, for obtaining for each stress range a product of a central stress value in a respective one of said stress ranges and a frequency value at the respective central stress value, for calculating a total amount of the thus obtained products in all of the stress ranges as a damage quantity, for decreasing said allowable loadage weight value when a load multiplying factor, which is calculated based on said damage quantity, is greater than a predetermined allowable value, and for outputting the loading completion signal to said loading completion informing means when a loadage weight, which is obtained based on pressure detection values of said pressure sensors, reaches said decreased allowable loadage weight value at a next loading time.
