PURPOSE:To perform normal ABS operation so as to improve engine braking effect by selecting the target change gear ratio by the output of a brake operating time target change gear ratio setting means, and the normal target change gear ratio by the output of a speed change reset judging means. CONSTITUTION:During ABS operation, this is judged by a brake operation judging part 66 in a speed change control system. A change-over part 68 is switched to a braking target change gear ratio setting part 67 so as to output a braking target change gear ratio is', and speed change is performed following this braking target change gear ratio is'. Accordingly, when a change gear ratio is smaller than the braking target change gear ratio is', a down-shift to the braking target change gear ratio is' is performed immediately and the change gear ratio if held to this target change gear ratio. The change gear ratio from the wheel side view becomes small compared to the case of a minimum change gear ratio, so that the inertial moment on the primary side of a continuously variable transmission is reduce to enable rotation even with small driving force. |
