Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] The basic principle of a lateral active collision avoidance system of the present invention is as follows: figure 1 shown.

[0031] The system includes a signal acquisition system, a signal processing system, and a controller.

[0032] The signal acquisition system includes on-board radar devices (at least six), image acquisition system and self-vehicle sensors. The signal acquisition system mainly acquires road information and self-vehicle information. And transmit the collected signal to the signal processing system.

[0033] The signal processing system processes the road information and self-vehicle information obtained by the signal acquisition system, and obtains information such as the relative distance, speed, azimuth, and driving direction of the front object, left object, right object, and rear object, as well as the speed of the self-vehi...

Abstract

The invention discloses a lateral active collision avoidance system and a control method thereof. The system comprises a signal acquisition system, a signal processing system, and a controller. The signal acquisition system comprises a vehicular radar set, an image acquisition system and a vehicle sensor. The input end of the signal processing system is connected with the output end of the signal acquisition system, and the signal processing system is sued for converting data acquired by the signal acquisition system into electrical signals and transmitting the data to the controller. The input end of the controller is connected with the output end of the signal processing system, and the controller is used for further processing the data acquired by the signal processing system. The lateral active collision avoidance system is capable of allowing vehicles to actively avoid collisions during running, damage caused by rear-end collisions can be reduced effectively, the damage of vehicle lateral collision upon drivers and vehicles and upon blocked vehicles and passengers can be reduced effectively, loss on economic property can be reduced effectively, a safer and more comfortable driving environment is provided for drivers, and driving safety is improved.

Description

technical field [0001] The invention discloses a lateral active collision avoidance system and a control method thereof, which realize collision avoidance of lateral obstacles of vehicles, and belong to the technical field of active safety. Background technique [0002] With the rapid growth of car ownership, road traffic safety has become an important issue of concern to governments and society. Statistics show that 70% to 90% of traffic accidents are caused by driver errors, while only about 3% are caused by vehicle failures. Although the use of more and more passive safety technologies (such as airbags, seat belts, pedestrian protection and energy-absorbing car bodies, etc.) has reduced the degree of injury in accidents, the root causes of traffic accidents have not been resolved. It is undoubtedly very useful to reduce the occurrence of traffic accidents if it is possible to remind the driver to pay attention before the accident and help the driver to take safety measur...
