Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the process of reversing into a garage, meeting cars in a narrow road, and driving on a curve has high requirements for steering operation technology and vehicle body trajectory prediction ability, and drivers with poor driving skills are likely to be out of judgment in the above process. Mistakes and operational deviations lead to safety incidents

Embodiment 1

[0055] Embodiment one (such as Figure 1 to Figure 9 shown): a precise driving guide, including a corner sensor 1 and a trajectory projection device 2, the rotation angle sensor 1 and the trajectory projection device 2 are connected through wired data transmission; the trajectory projection device 2 includes a single-chip microcomputer 201 and a trajectory projection lamp 202, The trajectory projection lamp 202 includes a laser emitting head 203 distributed in an array, which can be used to project the motion curve trajectory of the point. The laser emitting head 203 is controlled by the single-chip microcomputer 201 to turn it on and off. The single-chip microcomputer 201 is connected to the angle sensor 1 by wire; The instrument includes four track projection devices 2 for projecting different points and corner points; the angle distribution of the laser emitting heads 203 distributed in the array is different, and the laser pixels projected by it form a rectangular array, an...

Embodiment 2

[0057] Embodiment 2: The difference from Embodiment 1 is that the rotation angle sensor 1 is connected to the trajectory projection device 2 through wireless signal transmission.

[0058] Requirements and effects of Embodiment 2 relative to Embodiment 1: the wireless signal transmission device of the above embodiment requires fast and stable transmission speed; this embodiment is easy to install.

Embodiment 3

[0059] Embodiment three (such as Figure 10 As shown above): The difference from Embodiment 1 is that the trajectory projecting device 2 projects the curved surface trajectory of the line movement, and the distribution width of the rectangular array of laser pixels ranges from -2m to 4m (taking the trajectory projecting device 2 as relative to zero);

[0060] The effect of the third embodiment compared with the first embodiment: the trajectory image projected by this embodiment is clear and intuitive, and can more comprehensively reflect the area covered by the rigid body motion.

Abstract

The invention discloses a precise driving guiding instrument and a vehicle with precise guiding. The precise driving guiding instrument comprises a turning angle sensor and track projecting devices capable of being used for projecting curves or curved surface tracks, and the turning angle sensor and the track projecting devices are in transmission connection through wired or wireless signals. The vehicle with precise guiding is provided with the precise driving guiding instrument. The track projecting devices of the precise driving guiding instrument are installed on the head and the tail of the vehicle body, and the turning angle sensor of the precise driving guiding instrument is installed in a steering system of the vehicle. According to the precise driving guiding instrument and the vehicle with precise guiding, the traveling tracks of the head or the tail of the vehicle can be visually displayed in advance, a driver can conveniently and visually observe the traveling tracks of the head or the tail of the vehicle under current steering, and precise guiding can be achieved on steering.

Description

technical field [0001] The invention relates to a vehicle driving assistance device, in particular to a driving precision guidance instrument and a vehicle with precise guidance. Background technique [0002] With the improvement of people's living standards, vehicles have become an alternative tool for most people; vehicle driving technology has also increasingly become an important skill in people's lives. The learning of driving skills is widely sought after by people, but vehicle driving skills cannot reach a certain level in a short period of time, and usually need a long period of continuous accumulation. [0003] During the driving process, for some drivers with relatively short driving experience, reversing into the garage, meeting cars in narrow lanes and driving in curves is usually the most troublesome and fearful thing, and it is also the process most prone to accidents. For example, during the process of reversing into the garage, the driver has a poor sense of...
