Embodiment 1
[0029] see figure 1 , figure 1 It is a kind of automobile reversing automatic collision avoidance system according to the present embodiment 1, comprising an automatic sensing module, a central control module, an emergency braking module, a clutch control module, a vehicle speed limit module and a scene selection module, and the above-mentioned multiple components are connected through the CAN bus to communicate.
[0030] The automatic sensing module is arranged at the rear of the car, which can detect the distance between the rear of the car and the obstacles behind, and transmit the relevant data to the central control module. In this embodiment, an ultrasonic distance sensor commonly used in the market is selected and placed in the Tail, it is convenient to accurately measure the distance between the car and the rear obstacles. Of course, an infrared distance sensor, an image distance sensor, or a mechanical pop-up sensor mechanism can also be used here to achieve the sam...

The invention discloses an automatic anti-collision system for automobile reversing. The system comprises an automatic induction module and a central control module, the system comprises an emergencybraking module, a clutch control module, a vehicle speed limiting module and a scene selection module. Wherein the plurality of components are communicated with one another through a CAN bus; the central control module receives the data information transmitted by the automatic induction module; selection is carried out according to different scenario selection modules; related instructions are sent to the emergency braking module, the clutch control module or the vehicle speed limiting module; wherein an interval exists between the time when the central control module sends a braking or braking releasing instruction to the emergency braking module and the time when the central control module sends a related instruction to the clutch control module, and the time when the central control module sends the related instruction to the emergency braking module is earlier than the time when the central control module sends the related instruction to the emergency braking module. According to the automatic anti-collision system for automobile reversing, internal parts of an automobile can be better protected, and different crowds can select reversing modes more suitable for themselves through the multi-scene selection mode.
Description
technical field [0001] The invention relates to the technical field of automobile control, in particular to an automatic anti-collision system for automobile reversing. Background technique [0002] Cars are an indispensable means of transportation in our daily life and work. The existence of cars facilitates people's travel and improves the efficiency of cargo transportation. Now that the economy is developing, cars have gradually entered thousands of households. All kinds of cars can always be seen in the process of cargo transportation. But while cars are more and more integrated into our lives, the casualties and vehicle damage caused by various accidents also make us pay more attention to car safety. [0003] In daily life, reversing is an operation that all vehicles will encounter. Reversing safety is also a problem that many car manufacturers focus on designing and solving. Many sensing and imaging reversing assistance devices on the market cannot solve many complex ...
