Problems solved by technology

But, also there are two problems at the same time: the first, early warning form usually adopts sound or visual form, and this early warning form can only provide collision warning signal to the driver, can not be used for prompting the driver in non-dangerous situations
Second, when there is an accident risk, giving an alarm to the driver cannot completely avoid the accident. The timing of the alarm and the driver's acceptance of the alarm signal will affect the effectiveness of this type of alarm system

Embodiment Construction

[0022] In the case of low visibility, during the normal driving of the vehicle, the driver can be reminded in real time and vividly, and the driver can be informed of the position and speed of other vehicles, the relative motion relationship between the vehicle and other vehicles, etc., so that the driver can achieve a similar normal Safe driving under visibility conditions, avoiding dangerous situations that cause accidents, and improving driver's driving confidence. In the case of low visibility, during the normal driving of the vehicle, the prompt to the driver should be earlier than the current collision warning device, so as to avoid the occurrence of dangerous situations to a large extent.

[0023] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments thereof.

[0024] refer to figure 1 , This embodiment takes the lidar as an example for illustration. In the low-visibility...

Abstract

The invention relates to the technical field of driver vision auxiliary devices and discloses a driver vision auxiliary device and a driver vision auxiliary method. The device comprises a radar, a speed sensor, a processor and a display device, wherein the radar is used for detecting the shape of a front road and other vehicles on the front road and sending the detected information to the processor; the speed sensor is used for measuring the speed of a bicycle; the processor is used for processing the received detection information and the speed of the bicycle in a combination manner; and the display device is used for displaying the driving environmental data. The device disclosed by the invention is simple in design, high in reliability, and visual and reliable in graphical display, and can be used for realizing the early warning of non-dangerous conditions in the case of low visibility so as to avoid the occurrence of accidents and ensure the safe driving of the vehicles.

Description

technical field [0001] The present invention relates to the technical field of driver's visual assistance, and more specifically, to a driver's visual assistance device and a visual assistance method thereof. Background technique [0002] The driver's visual observation ability will be severely weakened under low visibility conditions, such as in foggy, snowy and heavy rainy weather, the driver's visual range will be greatly reduced. Accidents in low-visibility conditions are mostly caused by the driver not observing other vehicles, which causes the distance between the own vehicle and surrounding vehicles to get closer and closer. When the driver finds the existence of other vehicles, it is often too late to brake and cause a collision accident. [0003] At present, collision warning is mostly used to solve the problem of safe driving under low visibility conditions. By using ultrasonic sensors, ranging radars or infrared sensors to detect other vehicles around the vehicle,...
