Problems solved by technology

The sound waves are emitted and received by the probe, and the sound waves run at the speed of sound. Because the sound waves are reflected and refracted, the ultrasonic radar is more interfered and has no good measurement accuracy for measuring obstacles.

Abstract

The invention provides an automobile safe driving auxiliary detection system and method. The automobile safe driving auxiliary detection system comprises a plurality of microwave radar sensors, a digital signal processor, a display system, a control circuit and a plurality of image sensors; each image sensor is driven by a driving motor to change in view angle direction; wherein, each microwave radar sensor monitors such data as positions of barriers within a certain range surrounding a vehicle and speeds of nearby vehicles in real time; by means of control of the digital signal processor on the driving motor and the control circuit, images acquired by the image sensors are displayed through the display system. According to the automobile safe driving auxiliary detection system and method, the view angles of the image sensors are controlled according to the position information of barriers monitored by the microwave radar sensors, such that a view angle range of one individual image sensor is maximized and a surrounding dead zone of a vehicle can be displayed by means of the fewest cameras; more receiving antenna channels may be simulated by means of a relationship of different transmitting antennas, and therefore, the resolution of angle measurement is higher without causing remarkable increase of the circuit cost.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a large-scale automobile safety driving auxiliary detection system and method. Background technique [0002] In recent years, traffic accidents have occurred frequently in our country, causing casualties and property losses. The severe social situation has made people pay more and more attention to car safety. In the process of driving, most accidents are caused by improper operation of drivers. Inattention, fatigue driving and other objective factors exist. When dangerous situations occur in the surrounding environment of the vehicle, the driver’s attention is not aroused, resulting in operational errors and accidents. Especially for large vehicles, due to the long body and narrow viewing angle range, the vehicle in the When turning, due to the existence of the inner wheel difference, the turning radius is relatively large. At the same time, due to the existence of la...
