【発明の名称】無段変速機用変速制御装置の初期化装置
Document Type and Number:
Japanese Patent JP3384156
Kind Code:
B2
Abstract:
A controller (17) obtains a target input rotating speed (Nis) based on a vehicle running speed (VSP) and a throttle valve opening degree (TVO), drives a motor (23) by the use of a corresponding instruction value, and operates a speed change control valve (21) through a link (22). The controller (17) makes the motor (23) rotate to a hardware limit position in a side corresponding to a lower speed ratio side when the vehicle is in a stopping condition, and then makes the motor (23) rotate in the counter direction to return to a position corresponding to the lowest speed change ratio. On this occasion, the instruction value of the motor (23) is initialized to "0" corresponding to the lowest speed change ratio. When the vehicle is in a running condition, an actual speed change ratio is calculated, from which the motor position is inferred. Then, the instruction value of the motor (23) is initialized as a value corresponding to the inferred position thereof. Thus, a switch becomes unless in order to make the motor rotate to the position corresponding to the lowest speed change ratio position, further the initialization is realized not only when the electric power is turned on, so that the times of the initialization can be increased.
