Title:
CONTROLLER OF DRIVING APPARATUS FOR CARS
Document Type and Number:
WIPO Patent Application WO/2005/080112
Kind Code:
A1
Abstract:
A speed change mechanism for cars for switching between stepless and stepped speed change states and a controller capable of suppressing the switch shock caused when the speed change state is switch-controlled and improving the durability of the engaging device. A speed change mechanism (10) capable of switching between electrical stepless and stepped speed change states by switch-controlling the disengagement and engagement of a switch clutch (C0) or a switch brake (B0). When the speed change state is switched to the stepless speed change state by disengaging the switch clutch (C0) or switch brake (B0) by means of switch control means (50), a first motor (M1) is controlled by motor control means (82) so as to generate a torque. Consequently, the torque is adequately changed from the reaction force torque by the switch clutch (C0) or switch brake (B0) to the reaction force torque by the first motor (M1). As a result, the switch shock caused by switch control and the rotational speed difference of the engaging device itself are suppressed, and the workload in the disengaged state is reduced, thereby improving the durability of the engaging device.
