Abstract

PURPOSE:To enhance the attention arousing effect by displaying the registration pattern on a display, only in the case where the truly dangerous state is estimated. CONSTITUTION:An obstacle sensor 4 catches an obstacle which exists on the periphery of a vehicle, and outputs the measurement signal (a) corresponding to the separation distance L up to the obstacle. When the measurement signal (a) which exceeds the previously set dangerous distance value H is outputted, a danger signal judging means 5 outputs a danger signal (b). When the danger signal (b) is outputted, and an operation signal (c) is outputted through a connecting means 11, accompanied with the operation (e.g. brake pedal operation) of an operating means 7 for the vehicle, a driving signal (d) is outputted from a driving means 10. Accordingly, the registration pattern (e.g. 'STOP') corresponding to the operation is displayed on a display 1. When the danger signal (b) is not outputted, the registration pattern is not displayed even if operation is carried out. Since the registration pattern is displayed only in the case where the truly dangerous state is estimated, the attention arousing effect can be enhanced.

Can be set to any number of characters and symbols such as "Turn to the left / please be careful", "Turn to the right", "STOP", "Stop", "Parking", etc. The storage means 2 for storing the registered pattern and the calling means 3 are connected to each other, and a batch display or a scroll display is made in the case of a long sentence, and the display 1 is arranged at a position where it can be seen through from the rear glass, side glass, etc. .

An obstacle sensor 4 is, for example, a laser type, an ultrasonic type, or an infrared type, and is arranged rearward at the rear of the vehicle and / or laterally at the side of the vehicle. The measurement signal a is output according to the distance L to the obstacle existing around the vehicle.

Reference numeral 5 denotes a danger discriminating means, which is connected with a distance setting means 6 for setting a dangerous distance value H which is expected to cause a collision accident in advance, and compares the dangerous distance value H with the separation distance L. When a measurement signal that exceeds a preset dangerous distance value H is output, that is, when the dangerous distance value H> the separation distance L, the dangerous signal b is output.

Reference numeral 7 is an operating means, 8 is an operation informing means, and 9 is an annunciator, all of which are already installed in the vehicle. The operating means 7 is, for example, a direction indicating lever, a brake pedal, a change lever or the like. The operation informing means 8 indicates an electric circuit of the vehicle, and the informing device 9 is, for example, a direction indicator which is turned on by operating a direction indicating lever, a brake lamp which is turned on by operating a brake pedal, and a rearward operation of a change lever. The indicator 9 indicates a back lamp or the like, and the informing device 9 is driven via the operation informing means 8 by the operation signal c output from the operating means 7.

Reference numeral 10 denotes a driving means, which is the operation signal c.
An AND circuit for connecting the receiving means 11 for receiving the operation signal c and outputting the operation signal c to the driving means 10, and for driving the display 1 when the operation signal c is output and the danger signal b is output. When the AND condition is satisfied, the drive signal d is output to the display unit 1. In this case, the registered pattern corresponding to the operation signal c in the storage unit 2 is the calling unit 3.
The selected pattern is selected and called by, and the registered pattern is displayed on the display 1.

Reference numeral 12 denotes a correction means, which is connected to the danger determination means 5, and in this case, the correction means 12 includes a vehicle speed sensor 13 for measuring the speed of the vehicle, an infrared sensor capable of measuring the temperature of the road surface, etc. A road surface sensor 14 for detecting the condition, rain / snow, and dryness is connected, and the road surface sensor 14 is arranged at the bottom of the vehicle toward the road surface, and the correction means 12 sets the above-mentioned dangerous distance according to the vehicle speed and the road surface condition.
