摘要： PROBLEM TO BE SOLVED: To provide a desired vehicle deceleration without performing a complicated control operation by a driver in the decelerating traveling of a vehicle by providing a regenerative braking torque control means for controlling so as to impart a prescribed regenerative braking torque every gear ratio. SOLUTION: An ECU 7, for example, controls an inverter 4 and performs a so-called regenerative generation for working a motor generator (M/G) 3 as an engine and converting the rotating energy of a rotor coil into electric energy. The regenerative braking torque generated by the regenerative generation acts on wheels through a reduction gear 75, an automatic transmission(A/T) 2, a propeller shaft 6, a differential gear 8, and a drive shaft 9. The ECU 7 controls the inverter 4 so that the regenerative braking torque by the motor generator(M/G) 3 corresponds to the regenerative braking torque determined every reduction gear stage of the automatic transmission(A/T) 2 to provide a desired vehicle deceleration every reduction gear stage.

摘要： PROBLEM TO BE SOLVED: To relax extrusion feeling generated by engaging a forwarding clutch when an engine is restarted. SOLUTION: When restart of an engine is executed by a reason not based on a driver's intention of starting a vehicle (for instance, reduction in a charging amount of a battery, etc.), execution of rapid pressure intensifying control is ceased to retard a supply command (S330→S380→S390) of an oil pressure, so that engaging timing to a predetermined clutch of a transmission is retarded as compared with a case (S340→S400) of restarting an engine by a reason based on the driver's intention of starting the vehicle.

摘要： PURPOSE: To prevent generation of gear noise and shift lock by making a gear train of an astern stage of a constant engagement type and connecting it by a speed change stage selection device with a synchronizer on a twin clutch type speed changer changing speed by way of changing a power transmission route by means of furnishing two pieces of clutches. CONSTITUTION: First and third speed stage drive gears I1 , I3 are fastened on an output shaft J1 of one of two pieces of clutches C1, C2 connected to a speed changer input shaft Ji, and second and fourth speed stage drive gears I2 , I4 and an astern stage drive gear IR are fastened on the other output shaft J2. Subsequently, each of driven gears O1 -O4 constantly engaged with each of the drive gears I1 -I4 is arranged on a speed changer output shaft Jo, and it is selectively engaged. Additionally, two intermediate gears M1, M2 constantly engaged with each of the gears IR, O1 are arranged on a countershaft Jm in parallel with the input and output shafts. Thereafter, speed change without gear noise and shift lock is realized by having a speed change stage selection device with a synchronizer carry out each selective connection.

摘要： PURPOSE:To make it possible to obtain a proper creep torque automatically in accordance with a steering angle by providing a steering angle sensor detecting the steering angle of a steering wheel and a steering-angle- corresponding torque control means which generates a larger creep torque as the steering angle becomes larger. CONSTITUTION:A torque control of an electric motor 12 is conducted so that a creep torque be generated when prescribed creep control conditions are satisfied. This driving force control device is equipped, in particular, with a steering angle sensor 70 which detects the steering angle of a steering wheel and with a steering-angle-corresponding torque control means, e.g. a computer 54 for a motor control, which conducts the torque control of the electric motor 12 so that a larger creep torque be generated as the steering angle becomes larger. According to this constitution, a vehicle can be made to run on the basis of the creep torque even when the steering angle is large and, for instance, garaging or the like can be executed easily only by an ON-OFF operation of a brake.

摘要： PURPOSE:To simplify constitution of a planetary gear mechanism on the auxiliary shaft side and to simplify constitution of not only a gear shift device but also the whole of automatic transmission by a method wherein a rotation direction in which a reverse speed is set is reversed a planetary gear mechanism on the main shaft side to which torque is inputted. CONSTITUTION:A gear shifting device is provided with three clutch means K1, K2, and K3 and three brake means B1, B2, and B3. Through engagement of two frictional engaging devices thereof, a five forward one reverse speed is set. Since three in a number suffice for clutch means the whole of which is rotated, a necessary space containing a hydraulic servo mechanism to drive the frictional engaging device is reduced and size is reduced as a whole. By arranging clutch means K1 and K2 and brake means B1 and B2 to a planetary gear mechanism 1 on the main shaft 3 side, a rotation direction for a reverse speed on the main shaft 3 side can be reversed, resulting in simplification of constitution of the auxiliary shaft 4 side.
