摘要： A method is provided to detect, without the use of G-sensors, possible cascade locking in a four-wheel drive vehicle equipped with wheel speed sensors. The method measures the speed of each wheel with the respective wheel-speed sensor, and derives an estimated vehicle speed and a front and rear speed difference between the front and rear wheel speeds from the wheel speeds. When the deceleration of the estimated vehicle speed is smaller than a first threshold value and the absolute value of the front and rear speed difference is larger than a second threshold value, and if the change in the speed of the front wheels is smaller than the change in the front and rear speed difference at a time when the absolute value of the difference diminishes, then cascade locking of the four wheels is deemed to be starting.

摘要： A method is provided to compute the probable body speed of a vehicle equipped with a mini tire as a spare tire, specifically when the mini tire is mounted. The wheel speeds of the four wheels are measured, and if the speed does not satisfy the predetermined formula relating to the wheel base and tread of the vehicle to a wheel speed, then a probable vehicle body speed is derived by the normal method. The speed thus derived is corrected by the diameter of the mini tire to compute a new probable vehicle body speed.

摘要： A method is provided to correct the wheel speed for a vehicle equipped with a mini tire as the spare tire plus a nonvolatile memory device. The presence or absence of a mounted mini tire is detected while the vehicle is moving, and if a mini tire is mounted, the mounting information is stored in the nonvolatile memory. If an antilock control is triggered after the vehicle is restarted and in motion, a correction is made for the mini tire using the mounting information stored in the nonvolatile memory.

摘要： A method of an accurate detection of a spinning vehicle wheel. Observed wheel speeds are derived by measuring the speed of each wheel and the slowest speed is set as the slowest observed wheel speed. A maximum probable wheel speed is derived by multiplying the slowest observed wheel speed by the ratio of the maximum wheel speed to the slowest wheel speed for a given minimum turning radius. The maximum probable wheel speed is compared with an observed wheel speed and if the observed wheel speed is greater, the wheel is deemed to be spinning.

摘要： The present invention is intended to, when rotation of a mirror rotation unit in a power-folding mirror is mechanically locked and its drive motor is thereby locked, make it possible to correctly detect this locked state. A motor 10 for a power-folding mirror is reversibly driven by an H-bridge drive circuit 12 formed of FETs 1 to 4. When the motor 10 is driven in normal rotation by turning the FETs 1 and 4 on and turning the FETs 2 and 3 off, the FET 1 is periodically turned off to detect a voltage of a terminal 10a of the motor 10 by means of a voltage detection circuit 14. When the FET 1 is turned off and the motor 10 is not locked, the motor 10 generates power by means of its inertial rotation, and when locked, the motor 10 generates no power, so the voltage detected by the voltage detection circuit 14 changes according to whether or not the motor 10 is locked. A CPU 20 determines whether or not the motor 10 is locked according to the voltage detected by the voltage detection circuit 14.
摘要翻译：本发明的目的在于，当电动折页镜中的反光镜旋转单元的旋转被机械地锁定并且其驱动电动机由此被锁定时，可以正确地检测该锁定状态。用于电力折叠镜的电动机10由由FET 1至4形成的H桥驱动电路12可逆地驱动。当通过使FET1和4转动并使FET2转动并驱动电动机10而正常旋转时，电动机10 3关闭时，FET 1周期性地关闭，以通过电压检测电路14检测电动机10的端子10a的电压。当FET1断开并且电动机10未被锁定时，电动机10产生通过其惯性旋转进行动力，并且当被锁定时，电动机10不产生动力，所以由电压检测电路14检测到的电压根据电动机10是否被锁定而改变。 CPU20根据由电压检测电路14检测到的电压来判断电动机10是否被锁定。

摘要： A control method can stop motor operation reliably when a mirror rotator is mechanically locked at a driven end of the mirror rotator. The control method operates a motor 18 according to battery voltage. The motor 18 is operated with an operating time set and is stopped after a lapse of the set operating time, where the operating time is a time required for the motor 18 to drive the mirror rotator 14 from the retracted position or the working position to the working position or the retracted position at which the mirror rotator 14 is locked by a stopper. The control method detects the battery voltage, and decreases the set operating time of the motor 18 when the detected battery voltage is high or increases the set operating time of the motor 18 when the detected battery voltage is low.

摘要： A method is provided for accurately controlling a vehicle having a mini tire mounted as the spare tire. A short-term correction coefficient and a long-term correction coefficient are computed periodically for the left and right wheels, and a probable lateral acceleration G is computed from the difference between the ratio of the short-term correction coefficient to the long-term correction coefficient for the left and right wheels. A revised probable lateral acceleration G' is computed using the value of the long-term correction coefficient fixed at the point at which the absolute value of the probable lateral acceleration G has exceeded a prescribed value and the most recent short-term correction coefficient, from which a decision is made as to the state of a turn. The most recent long-term correction coefficient is used to make a correction for a mounted mini tire.
