COOLING WATER SHORTAGE DETECTING AND WARNING DEVICE FOR A HYBRID VEHICLE AND A METHOD THEREOF, CAPABLE OF DETECTING THE AMOUNT OF CHANGE OF COOLING WATER AND INFORMING A DRIVER OF THE SHORTAGE OF THE COOLING WATER

摘要

PURPOSE: A cooling water shortage detecting and warning device for a hybrid vehicle and a method thereof are provided to induce vehicle maintenance in early times and to prevent the vehicle from being abnormally driven by rapidly informing a driver of cooling water shortage. CONSTITUTION: A cooling water shortage detecting and warning device for a hybrid vehicle comprises a current measurement sensor, a controller, and a cluster warning lamp(13). The current measurement sensor measures the consumed current of a water pump(14). The controller receives a signal from the current measurement sensor and controls on or off of the cluster warning lamp. The cluster warning lamp is installed on a cooling water temperature dashboard of a cluster and informs a driver of cooling water shortage.
