摘要： A speed ratio control system for a continuously variable transmission is provided, wherein an oil flowrate to a hydraulic servo of an input or an output V-shaped pulley device is varied by a flow control valve, so that a speed ratio between the input and the output sides can be continuously changed. The system determines a deviation between a target value and a measured value and corrects the measured value in accordance with at least the characteristics of the flow control valve, so that the deviation and a rate of change per unit time of the speed ratio, or the deviation and a rate of change per unit time of a rotational speed of the input or output pulleys, will have a linear relationship over the entire area of control. This system avoids poor feedback gain because of the non-linearity of the characteristics of the flow control valve. Thus, the feedback gain is acceptable over the entire area of control of the continuously variable transmission. Even when the conditions of use are different, the speed ratio (or the input or output rotational speeds) can be stably controlled without disturbing the response.
摘要翻译：提供了一种用于无级变速器的变速比控制系统，其中通过流量控制阀改变输入或输出V形滑轮装置的液压伺服系统的油流量，使得输入和输出端可以连续变化。该系统确定目标值和测量值之间的偏差，并且至少根据流量控制阀的特性来校正测量值，使得每单位时间的速度比的偏差和变化率，或者输入或输出滑轮的转速的单位时间的偏差和变化率将在整个控制区域上具有线性关系。该系统由于流量控制阀的特性的非线性而避免了较差的反馈增益。因此，反馈增益在无级变速器的整个控制区域都是可接受的。即使使用条件不同，可以稳定地控制速度比（或输入或输出转速），而不会影响响应。

摘要： A creep prevention control device for an automatic transmission apparatus for a motor vehicle. The creep prevention control device has a mechanism for preventing creep caused by the automatic transmission apparatus and a mechanism for increasing the idling speed of an engine of the motor vehicle. These mechanisms are controlled on the basis of signals generated by sensors for detecting operating conditions of the motor vehicles and indicative of the detected operating conditions. The mechanism for increasing the engine idling speed is actuated when rendering the creep preventing mechanism inoperative so that the creep prevention can timely be controlled and the engine can idle in an optimum condition at all times.

摘要： A control system wherein there are determined a first and a second target value in terms of engine horse power. The first target value is a function of depression degree of accelerator, while the second target value is a function of engine speed. The first target value is generated as an output signal when a deviation in engine speed is smaller, while the second target value is generated as the output signal when the deviation is large. Based on this output signal, a device to adjust combustible charge to the engine is controlled such that the engine produces the horse power indicated by the output signal.

摘要： A system for controlling the drive and dynamic braking of automobiles which comprises an automatic control line for varying the prime mover speed with a prescribed relationship maintained between the prime mover speed and the throttle angle changing with the depression or release of an accelerator pedal used with an engine-driven automobile provided with a continuously variable drive ratio transmission, said automatic control line including a cam bearing a specially designed cam surface and connected to a throttle through a link mechanism, a servo valve supplied from the cam with a pilot pressure signal corresponding to its rotation, an output speed responsive-pressure generating governor valve for supplying the servo valve with another pilot pressure signal corresponding to the prime mover speed, and an actuator for changing the drive ratio produced by said continuously variable drive ratio transmission through the selective operation of the servo valve, whereby, when the engine is driven by the depression of the accelerator pedal, the above-mentioned prescribed relationship between the throttle angle and the prime mover speed enables the engine to be driven by fuel consumed at a minimum level for its substantially complete combustion, preventing harmful gases from being evolved from the exhaust and, when the engine drive is slowed down by release of the accelerator pedal, dynamic braking can be effectively carried out.

摘要： A method is for determining a side slip angle during the cornering of a vehicle. The following variables are recorded and interlinked via a mathematical vehicle model with assumptions of the linear single-track model: a predetermined or measured position of the center of gravity between a front and rear axle, the current vehicle velocity, a current vehicle cornering motion variable, the current steering angle on the front axle. To simplify the determination of the side slip angle, it is determined under the assumption that the difference between the side slip angle and the Ackermann side slip angle is proportional to the difference between the Ackermann angle and the steering angle. The actual side slip angle is deduced from the relationship of the measured steering angle and the Ackermann angle based on the proportionality relationship of the Ackermann side slip angle theoretically present when driving through the same curve without slip.

摘要： A slip control method and arrangement for a drivetrain including a continuously variable transmission, forward-reverse clutch arrangement and an optional three-speed gearbox is described herein. The forward-reverse clutch arrangement includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. Accordingly, the clutch prevents the prime mover from stalling.

摘要： A speed change control system for a vehicle configured to reduce uncomfortable feeling of a driver when shifting an operating mode via the fixed mode. When a required drive force to propel the vehicle is increased, a controller shifts the operating mode from a first continuously variable mode to a second continuously variable mode via a fixed mode. In this case, the controller increases an engine speed to a first target speed from a point when shifting from the fixed mode to the second continuously variable mode, and further increase the engine speed to a second target speed calculated based on the required drive force. In addition, the controller reduces the first target speed with an increase in at least any one of a first elapsed time and a second elapsed time.
