IPC: B60L15/22
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To prevent a motor assist ratio of a transmission from changing due to shifting operation by interposing the transmission capable of changing its speed reduction ratio in a human power drive system and controlling power or time rate of work of a motor drive system according to changes in the power of the human power drive system using a predetermined conversion formula or a conversion map. SOLUTION: Continuous torque T estimated with interpolation means 80 and a crankshaft rotation speed N obtained from speed calculation means 78 are added up with an adder 81. The result is inputted to motor power target value calculation means 84. The means 84 has a target value stored corresponding to an actual value of human power in the form of a map or a formula and determines a target value of a drive force or a power of a motor 64 using a conversion map or a conversion formula, compares the target value with an actual value 100 of the motor power comparator 86, and controls the power of the motor 64 so that the comparative difference becomes zero. Thus, motor assist ratio of a transmission is prevented from changing due to shifting operation.

Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the molding failure due to thermal decomposition or carbonization of a resin in the temperature rising step by controlling a predetermined time until the temperatures of the sites of a nozzle and cylinder arrive at set target temperatures. SOLUTION: The difference between the set target temperature Txi of each site Ti and the present temperature Tni of the each site is divided by the common step number S via the entire sites, the increment Bi of the temperature of each one divided step is obtained at each site Ti, and the raised temperature target temperature Txij of the each temperature rising step (j) of the each site Ti is calculated. At the each step (j), it is waited until all the temperatures Tni of the respective sites Ti arrive at the temperature Txij, and it is shifted to next temperature rising step.  Thus, the temperature rising required times of the respective sites Ti are brought into coincidence until it arrives at the target temperature TxiS-1, i.e., the set target temperature Txi, and the mutual relation of the temperatures of the respective sites Ti of the respective rising steps is brought into coincidence with that at the time of arriving at the set target temperature.
