Abstract

The invention provides a control method and system for low-speed active safety execution of an automobile. A low-speed active safety execution system control strategy is designed, data information collected by a short-distance ultrasonic radar and a panoramic camera is collected, surrounding information is detected, and the problem that the automobile has the risk of colliding with obstacles within the range of 4 m around is solved; data of two sensors are fused, the influence of gradient changes on the distance value is considered, pressure buildup compensation is carried out on the initial pressure value of brake force, the action intention of a driver is analyzed, and coordination control is carried out over real-time operation behaviors of the driver and the functions of the low-speedemergency brake execution system control strategy; and the problem about driving active safety of the automobile in the low-speed state is solved, and for the active safety function of the vehicle inthe low-speed state, stability is increased, and safety reliability is improved.

Description

technical field

[0001] The invention belongs to the field of automobile electric appliances, and in particular relates to an active safety control strategy system in a low-speed state of a vehicle. Background technique

[0002] In recent years, my country's automobile market has increasingly high demand for active safety functions in low-speed driving conditions. There are more and more vehicles in cities, and there are many low-speed scenes of vehicles in life, such as: in congested roads, parking processes and low-speed passing Fork roads, etc., the driving safety requirements of vehicles at low speeds are also increasing. Therefore, it is necessary to propose an effective, reliable and more intelligent control strategy. Aiming at the low-speed driving state, we propose a low-speed emergency braking execution system control strategy.

[0003] At present, the industry has proposed many schemes that can provide active safety collision avoidance systems during driving. These...
