Ranging system for automobile

Abstract

The invention relates to the field of electronic measurement and control, and provides an automobile ranging system for an automobile. By means of the ranging system, obstacle detection can be conducted within the 360-degree range around a vehicle through an ultrasonic ranging system, especially in a low-speed state, a driver can visually see circumstances around the vehicle in the vehicle through the ultrasonic ranging system, a green hand is assisted in better grasping the safe distance, and scraping accidents are prevented. Meanwhile, on the condition that the vehicle is started, if a child or other obstacles pass through the detection range and enter measuring blind spots, a control system can control an alarm system to give the alarm to remind the driver to pay attention to the obstacles in a blind spot area in the front.

Description

technical field [0001] The invention relates to the field of electronic measurement and control, in particular to an automobile ranging system for automobiles. Background technique [0002] With the development of social economy, more and more people have their own private cars, and more and more cars are pouring onto urban roads, urban traffic is becoming more and more congested, parking is more difficult, and some drivers are not skilled in driving , The probability of small accidents such as car rubbing and bumping increases greatly. Especially during the rush hours of commuting in cities, it is more common for low-speed collisions to occur on congested urban roads. The main reason is that the driver's field of vision is not wide, and the existence of obstacles cannot be known in advance. The vehicle driver's field of vision in the cab is only 180 degrees at most, and the distance between the vehicle and obstacles can only be estimated by human eyes, which will cause in...

Problems solved by technology

[0004] Moreover, the existing low-speed anti-collision system is mainly used for reversing and parking. It can only measure the distance from the rear large-volume obstacle to the car body, but cannot display the object situation on the front and left and right road surfaces, that is, it cannot realize all-round obstacle avoidance. small measuring range

At the same time, the cost of the current low-speed anti-collision system is relatively high, and most of them are used in middle and high-end cars, but have not been popularized in low-end cars.

The current mainstream product of the low-speed collision avoidance system is only an independent control unit, which cannot be connected with the automobile digital information platform
