摘要： PROBLEM TO BE SOLVED: To provide a compact and inexpensive constant mesh transmission for vehicle which can reduce the feeling of deceleration during gear shifting. SOLUTION: During gear shifting, a driving torque from an engine 40 is not transmitted to an output shaft 20 if a first clutch 38 is released. However a flywheel 66 is connected to the output shaft 20 by engaging a second clutch 60 with slippage during the first clutch 38 is released by means of action of a torque assisting control means 100 and the feeling of the deceleration can be reduced during gear shifting, since an output torque TOUT of the output shaft 20 is maintained at certain speed without stall due to the driving torque from the flywheel 66 rotating at predetermined speed is transmitted to the output shaft 20. Furthermore, the manufacturing cost of the transmission 12 is reduced that the output shaft 20 is driven by the flywheel 66 and the size of the transmission 12 becomes more compact making the flywheel 66 relatively small by enabling to store larger energy in it increasing the rotating speed NF of the flywheel 66 before engaging the second clutch 66.

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.
