A pressure control device of an automatic transmission in which duty ratio of speed gear changing solenoid is controlled, when a shift is done from D, 2 or L range to P, R or N range and back again to D, 2 or L range, such that the duty ratio is maintained at 0% to ensure a sufficiently large apply flow rate and then increased followed by a progressive decrease towards 0%. The time over which the duty ratio is maintained at 0% is shortened in an amount which is determined in accordance with the time elapsed till the shift back to the D, 2 or L range, whereby an abrupt application of the engaging hydraulic pressure to a clutch is avoided to minimize a shock which is generated at the time of shifting. When a shift is done for the first time from N to D range after turning on of the ignition switch, the time over which the duty ratio is maintained at 0% is prolonged so as to increase the rate of supply of the hydraulic oil to oil passages and hydraulic pistons of clutches for operating rotational elements of the automatic transmission, so that sufficiently large quantity of oil is maintained at the time of the first shift from N to D range shortly after the start of the engine, thereby minimizing a shock.

An image processing apparatus includes: a detecting unit configured to detect a motion vector from an input image signal acting as the image signal for each of chronologically input pixels; a determining unit configured to determine whether the input image signal in terms of a level meets a predetermined condition; and an interpolating unit configured such that if the input image signal is not found to meet the predetermined condition, then the interpolating unit interpolates and outputs an input image signal intermediate signal interposed at a predetermined point in time between the input image signal and a preceding input image signal that precedes the input image signal, in accordance with the motion vector, and if the input image signal is found to meet the predetermined condition, then the interpolating unit allows the input image signal to be output unchanged as the input image signal intermediate signal.

A vehicle route guidance system includes a map information storage section 10 which has a road type storage section 10a for storing various types of roads such as toll roads, express highways and motorways. A route guidance control section 26 reads out map information including road type information and route information. A road type change point detecting section 26a detects a road type change point. The route guidance control section 26 causes a display 28 and a voice controller 30 to perform the route guidance when a vehicle approaches a point a given distance short of the road type change point. The voice controller 30 responds to the instruction from the route guidance control section 26 to announce the route guidance for informing the driver of the entry to a toll road, express highway or motorway.

In accordance with the invention, the mounting position of a throttle opening sensor is adjusted in such a manner that the output voltage of the sensor attains a value a value of V.sub.100 at a throttle opening of 100%. When execution of the system program starts, V.sub.0 is stored in memory as initialized voltage data at a throttle opening of 0%. A throttle opening .theta..alpha. corresponding to sensed voltage data V.alpha. is calculated in an arithmetic unit in accordance with the following equation: ##EQU1## The throttle opening - output voltage characteristic may change due to an error in mounting the throttle opening sensor, a change in the length of the throttle cable caused by a temperature variation, or a change in resistance value caused by aging. If such is the case and a voltage V'.sub.0 greater than the previously stored voltage V.sub.O prevailing at the throttle opening of 0% is sensed, then V'.sub.0 is stored in memory as new voltage data corresponding to the throttle opening of 0%. Thereafter, a throttle opening .theta.'.alpha. corresponding to sensed voltage data V'.alpha. is calculated in accordance with Eq. (1). Therefore, since an adjustment is made so as to absorb any variance in the throttle opening - output voltage characteristic of the throttle opening sensor, an accurate throttle signal can be obtained at all times despite a change in the characteristic of the throttle opening sensor when the sensor is mounted or due aging.

摘要:
A rate of change in vehicle velocity is calculated by comparing a present vehicle velocity signal and an immediately preceding vehicle velocity signal. If the rate of change in vehicle velocity is greater than a rate of change capable of being produced by actual traveling of the vehicle, a decision is rendered to the effect that the vehicle velocity sensor is faulty, fail-safe mode processing is executed and the automatic transmission is controlled in such a manner that traveling of the vehicle will not be impaired. Thus, if the vehicle velocity sensor malfunctions, the automatic transmission can be controlled so as not to impair traveling of the vehicle, thereby allowing the vehicle to travel safely and stably. The fail-safe function can be performed satisfactorily even if only a single vehicle velocity sensor is provided.
