Abstract

Provided is an inexpensive dozing-off drive prevention device capable of detecting driver's dozing-off quickly. This dozing-off drive prevention device preventing driver's dozing-off drive in advance is mounted in a vehicle. It is provided with a speed detection means (21) detecting speed of the vehicle changing at every moment, a dozing-off discriminating means 11a discriminating dozing-off when deceleration below predetermined speed is detected from monitoring speed determined in advance within a predetermined period of time based on the speed detected by the speed detection means (21), and an alarm means (17) giving an alarm for a driver when the dozing-off discriminating means (11a) discriminates dozing-off.

Description

technical field [0001] The present invention relates to a drowsy driving prevention device and a vehicle operation information collection device, more specifically, to a drowsy driving prevention device mounted on a vehicle to prevent drowsy driving and a drowsy driving prevention device. The operating condition data generated by the above-mentioned vehicle operating conditions is used as a vehicle operating information collection device for collecting operating information. Background technique [0002] In the transportation industry where goods are transported by business vehicles such as trucks, taxis, and buses, it is an important issue for transporters to thoroughly carry out safe transportation, especially when accidents occur due to drowsy driving. Since the damage is serious, a drowsiness prevention driving device that prevents accidents caused by drowsiness by issuing a warning based on the detected drowsiness state has attracted attention. [0003] As a device for...
