JPS6198639A - Operational conditions supervisory unit for vehicle - Google Patents

Abstract

PURPOSE:To obtain the data which can be used for repair or designing by supervising various machines and tools mounted on a vehicle by means of an operational condition supervising means and, when judged abnormal, issuing an alarm together with writing the operational record in a nonvolatile memory means. CONSTITUTION:An operational condition supervising means 1 consisting of a microcomputer supervises both the operational condition of controlled machines and tools such as a headlight, a flasher lamp, or a horn and the level of liquid such as battery liquid or brake liquid, which are detected by a detecting means 3. When the operation is judged abnormal, the supervising means 1 outputs a warning signal to a warning means 4 and indicates thereof on a display unit 5. At the same time, the means 1 outputs a signal which records the operational record of the machines and tools to a rewriting means 6 and writes it in a nonvolatile memory means 7, that is an EEPROM. By selecting a certain key by operating a selection means 8 on the keyboard, this memorized operational record can be displayed on the display unit 5, which can be used as the data for vehicle's repair or design.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is a vehicle driving condition monitoring device, more specifically, it monitors the conditions of various devices installed in the vehicle, displays an alarm when the driving condition is not normal, and This invention relates to a vehicle driving condition monitoring device that records the driving history of the vehicle.

(Prior art) Before driving a vehicle, it is necessary to check whether controlled devices such as headlights installed in a vehicle are operating normally and whether brake fluid, etc. is properly replenished. There is. By the way, while the vehicle is running, these devices may malfunction for some reason and may no longer be in proper operating condition.

For this reason, in railway vehicles, for example,
As shown in Japanese Patent No. 144702, a method has been proposed in which a recording unit records the changing state of each device before and after a failure occurs, and the stored information is analyzed when repairing the failed device to track down the failure. ing.

(Problem to be solved by the invention) However, when a failure occurs in a certain device, stopping the vehicle and repairing it will affect the operation of the following vehicles, so this system records the changed state of each device. The recording device is large and complicated, and is recorded so that it can be restored after the long poem has been written.

By the way, in motorcycles, automobiles, etc., when various devices malfunction or lack of hydraulic fluid, etc., the driver is immediately notified and the driving history of the device is used for repair or vehicle installation AI. There is a desire to record the information for use as materials.

This invention was made in view of the above circumstances, and it not only immediately notifies the driver when various equipment is no longer in a normal operating state, but also records the operating history of the equipment accurately and easily so that it can be repaired or damaged. Our first objective is to provide a vehicle driving condition monitoring device that can be used to design a vehicle.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention monitors various equipment mounted on a vehicle, and when it is determined that the equipment is not in a normal operating state on the first floor, an alarm signal is sent. and an operating state monitoring means for outputting a recording signal for recording the operating history of the device;
an alarm means for displaying an alarm on a display device based on the alarm signal; a writing means for writing an operating history of the abnormal equipment into a non-volatile P1 storage means based on the recording signal; and an operation history stored in the non-volatile storage means. The vehicle is characterized by having one selection stage for selecting the vehicle and displaying the driving history on the display device.

(Function) In this invention, the famous equipment installed in the i1 car is monitored 12 times.
, reverse driving condition) is determined to be abnormal, the first stage of driving condition monitoring outputs a warning signal and displays the warning on the display device to notify the driver. At the same time, a recording signal is output to write the operating history of the device into the first stage of non-volatile storage. The driving history stored in the non-volatile storage means is then selected by the selection means, and the driving history is displayed on the display device, so that it can be used as a resource for repairs, vehicle design, etc.
