If the automobile is difficult to brake or pushed forwards by a rear automobile, in order to ensure that pedestrians can completely avoid the automobile, the light projector is required to project at three meters in front of the automobile, the installation height of the light projector can be correspondingly calculated by knowing the angle of the light exit port, and the angle of the light exit port and the horizontal plane needs to be adjusted to enable the two-dimensional optical pattern to be projected as far as possible by considering that the height of a front bumper is about half a person.

Further, the light projector projects a two-dimensional optical pattern on the ground using laser light. The two-dimensional optical patterns can have different colors, and can also remind pedestrians in a flashing mode, the projected font is 'Song' body, the length and the width of the font are 300mm x 350mm, and the size of the font can be adjusted properly.

Further, be equipped with the speaker installation department on the front bumper, the speaker installation department is located the middle part of front bumper, is close to the position of grid, the speaker adopts modes such as screw to install on the speaker installation department, and the fast transmission of the sound of being convenient for also can avoid the invasion of rainwater, leads to the damage of spare part. The automobile is provided with a loudspeaker connected with a steering wheel and a loudspeaker used for a vehicle sound, the loudspeaker connected with the steering wheel is also arranged on the loudspeaker installation part and shares an installation point with the loudspeaker, and a component does not need to be additionally arranged, so that the automobile is simple and convenient.

Further, be equipped with the inductor installation department on the front bumper, the inductor is installed on the inductor installation department, adopts fixed modes such as screws to install and prevents to drop, road conditions in detection vehicle the place ahead that can furthest. Further preferably, the sensors are arranged at the front part and the two ends of the front bumper respectively, so that road condition information can be sensed better.

Further, the sensing range of the sensor is the range of 120 DEG and 150 DEG in front of the automobile.

Further, the controller is electrically connected with the vehicle-mounted computer. The controller is independent and belongs to the next-stage controller of the vehicle-mounted computer.

An automobile comprising an automobile reminder device.

When the vehicle normally runs, the reminding device is in a dormant state and does not participate in the work of the reminding device; when a person is present in front of the automobile, the automobile decelerates and walks slowly, the automobile stops moving when the automobile is close to the pedestrian, particularly when the automobile is close to the position of 3 meters, at the moment, the sensor of the automobile starts to work, the information of the pedestrian at the front end of the automobile is transmitted to the controller, the controller is transmitted to the vehicle-mounted computer, the vehicle-mounted computer transmits the obtained effective information to the controller through a series of operations and processing, the controller operates the light projector and the loudspeaker to work, at the moment, the light projector emits one light to the ground, three words of 'please pass' appear, and the loudspeaker can emit 'please pass' sound. The pedestrian can conveniently and quickly pass through the road through the given prompt information, and the waiting time of the vehicles and the pedestrian is saved.

Compared with the prior art, the utility model discloses following beneficial effect has: the pedestrian is prompted to cross the road through sound and characters, the safety of the pedestrian is protected, and the humanized design is increased; the controller senses the road condition in front of the automobile in real time, so that the work of the light projector and the loudspeaker is controlled, and the automobile can be developed more intelligently.
