Abstract: A safe driving support apparatus in a vehicle is used in a manner that prevents an over-reliance of a driver on a safety device by an application of a technique. That is, for example, an evaluation of driving operation is lowered when the vehicle has been under control of an avoidance control for avoiding an unsafe situation of the vehicle, and the lowered evaluation of driving operation is recorded on a memory medium as well as being notified for the driver after evaluation is being changed. A provision of the avoidance control may result in a suppression of a vehicular function that contributes to a comfort in the vehicle among functions provided by in-vehicle devices.

Abstract: In a communication system for downloading programs from a center to in-vehicle terminals, a center can check whether downloading has been completed normally or a program is operating normally in an in-vehicle terminal. According to the timing of activating a downloaded program, an in-vehicle terminal checks whether the program is activated to operate normally. The information is transmitted to the center. Based on the information, the center becomes aware of the fact that downloading has been completed without any problem and that the program is operating normally in the in-vehicle terminal.

Abstract: The invention aims to increase an expansion angle in a road surface direction in a short-distance area without setting a detection range one-sidedly and without sacrificing a maximum detection distance.A double-focus lens is integrally formed by disposing a short-focus portion in the vicinity of a center and a long-focus portion on the periphery of the short-focus portion. A light source is disposed at a distance slightly shorter than the focal length of the short-focus portion of the double-focus lens. When light is emitted from the light source to the double-focus lens, light emerging from the short-focus portion has a small expansion angle such as not to diffuse largely. Therefore, the emerging light can be caused to reach a long distance. On the other hand, light emerging from the long-focus portion has a large expansion angle such as to diffuse to some extent.

Abstract: A vehicular communication device includes a plurality of request switches, a request signal generator means, a transmitter, a receiver and a display. The request switches respectively designate a plurality of services which a user may request. The request signal generating means checks the operational conditions of all request switches in order to enable the user to operate at least two of the request switches substantially simultaneously. The request signal generator then generates a request signal on the basis of the checking. The transmitter transmits the request signal to a remote service facility. The receiver receives an acknowledgment signal received signal transmitted from the service facility. The display displays a message in accordance with the acknowledgment signal for assuring the user that the request signal has been received by the service facility.

Abstract: A control method performed in response to the occurrence of an abnormal sensor output during the operation of monitoring the output signal of a sensor and controlling the operation of an automobile device such as a wiper. A microcomputer detects the presence or absence of an abnormal value of the sensor output signal converted to digital form so that when the abnormal value is detected, the operation of the automobile device is selectively controlled in accordance with an engine operating condition indicative signal applied to the microcomputer.
