Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for confirming an object when driving a vehicle, and more particularly to a vehicle object confirmation for assisting a confirming operation when a driver enters the garage or performs a silent check or intuition. Related to the device.

[0002]

2. Description of the Related Art The amount of situation information obtained by silent observation when a vehicle is parked or the like is extremely small, and it is necessary to operate by intuition regardless of the technical level of the driver. Therefore,
There are devices that provide confirmation when parking a vehicle at a predetermined location with obstacles to assist in driving the vehicle.

[0003] As a general assisting device at the time of parking, there is a device which is provided with various sensors at four corners of the vehicle and at the front and rear to inform a driver of the situation of surrounding obstacles and the like. As such a device, there is a device that notifies a driver of the tone or the volume of the sound when the distance between the host vehicle and the obstacle approaches. Also,
2. Description of the Related Art There is a device or the like that displays the distance to an obstacle using a display lamp and notifies the driver of the distance between the vehicle and the obstacle.

In addition, in Japanese Patent No. 2741725, there is a control device in which various sensors are attached to a vehicle and information obtained from the sensors is processed by a microcomputer to instruct a driver to perform a driving operation. This is a parking guidance device that guides the vehicle to an appropriate parking position by performing a driving operation in accordance with a display of a lamp when parking.

[0005]

However, the conventional vehicle objective checking device has the following problems. 1. A conventional vehicle objective confirmation device informs a driver of a distance to an obstacle obtained from a sensor by a single method using a sound, a lamp, or the like. Such a method cannot cope with the case where the own vehicle approaches two or more obstacles. When the positional relationship between the obstacle and the vehicle is clear, the distance can be grasped. However, when the obstacle is unclear (shape or direction), the position of the obstacle close to the vehicle is determined. Cannot be determined, the effect of the vehicle objective confirmation device cannot be improved. 2. A device that instructs a driving operation when parking a car has the following problems. In the case of a beginner who is inexperienced in driving technology or a driver who is not good at putting in a garage, the driving operation at the time of parking according to the driving operation instruction is performed accurately. However, when the driving operation at the time of parking becomes more skilled, it becomes possible to operate before receiving the instruction, and the guidance operation at the time of parking is not required. In addition, a driver who relies on a device that teaches a driving operation does not improve the driving technique much, and cannot perform a parking operation in an automobile that does not have a device for guiding the driving operation during parking.

The present invention has been made in view of the above-mentioned problems in the prior art. An object of the present invention is to provide a vehicle objective checking device that can display information on obstacles at the time of parking to a driver in an easy-to-understand manner to grasp the state of the host vehicle and to park safely. is there.
