摘要： An estimated gradient value of a road is calculated based on a vehicle acceleration “A” and a time varying portion “A′” of a wheel speed. In a case that an acceleration corresponding value “Ggrad0” for the estimated gradient value is not regarded as indicating an exact figure, due to influences of disturbances, the acceleration corresponding value “Ggrad0” is corrected by a limiting value for rate-of-change with regard to the road gradient depending on respective vehicle speed, and by a limiting value for the road gradient. As a result, the acceleration corresponding value “Ggrad” for the estimated gradient value can be more exactly obtained.

摘要： In a cruise control system for a vehicle, a cruise ECU calculates a cornering resistance applied to the vehicle based upon a steering angle, when a vehicle turns. The cruise ECU calculates a speed reduction amount as a correction vehicle speed based upon the cornering resistance. The cruise ECU subtracts the correction vehicle speed from a set vehicle speed to set a target vehicle speed so that the vehicle speed becomes lower as the cornering resistance is larger. The cruise ECU controls the vehicle speed to be within a permissible speed range of the target vehicle speed.

摘要： When a vehicle is started on an uphill road, slip may easily occur between vehicle wheels and a sloping road surface. When vehicle condition is changed from its stopping condition to its traveling condition on the uphill road, vehicle acceleration is controlled in a feed-back operation in such a manner that a target acceleration is made smaller as road gradient becomes larger or coefficient of friction becomes smaller.

摘要： It is an object of the present invention to provide a vehicle automatic operation control device that can perform automatic operation of a vehicle while the actual acceleration favorably tracks the target acceleration. The device comprises a target required torque calculating part (31) which determines the target required torque from the respective calculated values of a feed-forward calculated value and a feedback calculated value, and an automatic operation control part D which causes the vehicle to operate automatically on the basis of the determined target required torque, and which performs slip suppression control that suppresses slip of the wheels when any of the wheels of the vehicle slip. In cases where slip suppression control is performed by the automatic operation control part (D), the target required torque calculating part (31) holds the feedback calculated value based on the deviation between the target acceleration and actual acceleration, and determines the target required torque from the respective calculated values of the held feedback calculated value and feed-forward calculated value.

摘要： A vehicle speed control device calculates a desired axle torque for maintaining a speed of a vehicle to a set speed, and conducts cruise control. Specifically, the vehicle speed control device calculates a drive force including a feedforward component corresponding to the set speed and a travel resistance against the travel of the vehicle, and a feedback component corresponding to a deviation of the set speed from the actual speed of the vehicle as a desired axle torque. The vehicle speed control device interrupts the cruise control when a requested drive axle torque requested by an accelerator operation during the cruise control exceeds the desired axle torque, and restarts the cruise control when the requested drive axle torque becomes lower than the desired axle torque.
