摘要： PROBLEM TO BE SOLVED: To make estimable the mass of a vehicle with high accuracy, irrespective of the type of the vehicle by taking in the output of a vehicle speed sensor, obtaining the accelerations at a plurality of time points by different driving forces, using a specified formula, and obtaining the driving force by referring to a map from the accelerator openings at the time points and a plurality of used gear ratios. SOLUTION: A mass estimator part 72 holds equation I for obtaining the vehicle acceleration α from the driving force F, vehicle mass W, vehicle running resistance, and road surface gradient θwherein μrW, μeAV2, WrA are vehicle running resistances. An acceleration calculator part 71 takes in the output V of a wheel rotation sensor 55 and differentiates it in time to calculate the vehicle acceleration. The mass estimator part 72 obtains driving forces FA, FB by referring to a map 74 from the accelerator opening at the time and a plurality of used gear ratios A, B, and substitutes accelerations αA, αB in Formula II to set up simultaneous equations, thereby obtaining the vehicle wt. W from the simultaneous equations where WrA, WrB are masses corresponding to rotary parts.

摘要： PROBLEM TO BE SOLVED: To improve engine speed change control while reducing fuel consumption in consideration of environmental protection. SOLUTION: The feature quantity of vehicle acceleration and the feature quantity of driving engine power are continuously measured. A gear shift speed range and a speed range with its boundary determined by lowest and highest attainable speed in a target gear can be set to a gear shaft method in an initial gear. The boundary of the gear shift speed range are determined at least by the lower gear shift speed and upper gear shift speed, and the boundary of the speed range are determined not only by the lower target speed but also by the additional speed. This gear shift method is started according to the measured acceleration. At the time is of starting gear shift in a large number of gear shift speeds, the lower target speed is attained by a gear shift method in a first limited state (high acceleration in low input speed and limited deceleration in low input speed). A gear shift method between the first limited state in the target gear and the highest attainable speed is started according to the measured quantity in the gear shift speed range in the initial gear.

摘要： PROBLEM TO BE SOLVED: To determine the gross vehicle connector weight by resetting the controlling parameter value to the specific default value, when the generation of the predetermined set of vehicle operating condition representing the change of the vehicle load, is sensed. SOLUTION: An input axial speed sensor 98, an engine speed sensor 99, and an output axial speed sensor 100 are used for determining GCW (gross vehicle connector weight). ECU processes an input signal 122 from the sensors 98-100 according to the specific logical regulation, and sends a command output signal 124 to an engine ECU (ECUE), an actuator 120, a display device or the like. The vehicle GCW can be obtained from GCW=(T1-T2)/[(A1-A2)×C]. In the formula, T1 is the wheel torque in the time t1, T2 is the wheel torque in the time t2 , t1 and t2 are the times close to each other (within several seconds), Al is the vehicle acceleration in the time t1 , A2 is the vehicle acceleration in the time t2 and C is rolling radius/gravitational constant.

摘要： PURPOSE: To carry out smooth up-shift on a mechanical gear transmission at least a part of which is automated. CONSTITUTION: Only a selected shift decided to be practicable is practiced by evaluating practicability of selected up-shift of an automatic mechanical transmission 10 by an electronic control device 106. An effective value of a parameter showing engine deceleration is reduced so as to at least temporarily judging practicability of the up-shift more negative (that is, so that a stricter demand for practicability of the selected up-shift is set up) in accordance with nonconformity of a system that the up-shift decided to be practicable cannot be consequently completed due to a working state of a vehicle, and logical regulation to evaluate practicability of the up-shift is corrected so as to increase a parameter effective value showing vehicle deceleration. Consequently, it is possible to constantly carry out smooth up-shift regardless of the working state of the vehicle.
