Title: Starting variable speed control device for gear ratio continuously variable transmission
Inventor: SAKAI HIROMASA
IPC: F16H37/02
Filed: 2000-11-10
Abstract: PROBLEM TO BE SOLVED: To change the speed of a gear ratio continuously variable transmission without depending on the engagement of a clutch in starting in a manual gear stage and without worsening an accelerating feeling. SOLUTION: In a power circulation mode, a continuously variable transmission is controlled to have a gear ratio corresponding to a neutral point where the output rotating speed of the gear ratio continuously variable transmission is zero, thus realizing the stop of a vehicle in an M-range. In starting, starting rotating speed Ninst which is speed change start input rotating speed when vehicle speed VSP is zero in any of speed stages M1-M7 as it is clear from a manual shift line shown in the figure, is made input rotating speed slightly higher than the idling speed of an engine, to start a speed change from the neutral point GNP for the stop of the vehicle into the manual selected speed stages (M1-M7: normally M1 because of starting) when the input rotating speed Nin becomes the starting rotating speed Ninst by depressing an accelerator pedal.  The engagement of the clutch hard to control is dispensed with when starting in the M-range, and a problem that it is impossible to expect sufficient start acceleration, does not arise since engine rotation is increased when starting.
