Warning device for a vehicle
First Claim
1. A warning device for a vehicle comprising:
- a starting check unit sensor group including a plurality of sensors respectively provided at a set of predetermined check points in the vehicle for detecting an abnormal state which may exist in any of the check points at a starting check time and thereupon producing an output signal;
a driving check unit sensor group including a plurality of sensors respectively provided at another set of predetermined check points in the vehicle for detecting an abnormal state which may exist in any of said other set of check points during driving of the vehicle and thereupon producing an output signal;
indication means provided in correspondence to each of said sensors;
an alarm buzzer;
designation means for instructing conduction of a test at a specified rotated position of a key switch before a starter is on;
a first control circuit driven by operation of a test switch by an operator upon instruction by said designation means for driving all of the indication means and the alarm buzzer for a test;
a second control circuit for connecting said starting check unit sensor group with only the indication means corresponding thereto after said test thereby to indicate an abnormal state existing in any of the starting check points; and
a third control circuit including a first means for driving all of the indication means and the alarm buzzer in response to the output signal of any sensor of said driving check unit sensor group while the key switch is on and second means for thereafter driving only the indication means corresponding to the check point at which the abnormal state exists.

Abstract
A warning device for a vehicle is capable of checking a disorder in the vehicle in a sequential order through a dialog between the device and an operator. The device first indicates conduction of a test before a starter is turned on and the operator depresses a test switch in compliance with this indication to test whether all indication units and buzzer can operate normally. After finishing this test, any disorder which may exist at various starting check points such as a hydraulic fluid level and a radiator water level is detected by an associated indication unit. After the starting check up has been completed and the starter is turned on, driving check points such as a torque converter oil temperature and a brake air pressure are constantly watched and if there occurs any disorder in such check points, the operator is informed of such disorder by operation of all of the indication units and the buzzer. The operator then operates only the indication unit associated with the check point where the disorder has occurred by manipulation of a check switch.
