Problems solved by technology

It is worth mentioning that at present, many low-end and mid-range vehicles only have radar sensors around the vehicle body. After the radar collected signals are processed, an audible and visual prompt signal is sent without brake intervention. This makes parking operations still a must for drivers. problems faced
[0003] In addition, even if the car is equipped with a parking assist system, it is only responsible for active steering and cannot perform active braking, so that the vehicle has a potential collision

Abstract

The invention provides an auxiliary braking control method and system during the parking of an automobile. The method comprises the following steps: detecting the current speed of the automobile; if the current speed is lower than or equal to a preset speed, further detecting whether a distance between the automobile and barriers is smaller than or equal to a preset distance; if yes, alarming, and further judging whether the auxiliary braking is carried out or not according to the state of an accelerator pedal of the automobile, the duration time of the state of the accelerator pedal, and the change trend of the distance between the automobile and the barriers; and if the auxiliary braking judged to be carried out, controlling the automobile to automatically brake so as to prevent the automobile from colliding the barriers. According to the method disclosed by the embodiment of the invention, the automatic braking can be carried out, the automobile is prevented from scraping and colliding the surrounding barriers during parking, so that the safety of the automobile is improved. The invention further provides an auxiliary braking control system during the parking of the automobile.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an auxiliary braking control method during automobile parking and an auxiliary braking control system during automobile parking. Background technique [0002] The automatic parking system has been widely used. The existing parking system can actively steer according to the parking trajectory, but requires the driver to step on the accelerator pedal and the brake pedal to control the longitudinal movement of the vehicle. When the vehicle is parked in a narrow and complex environment, it is very prone to scratching collisions. It is worth mentioning that at present, many low-end and mid-range vehicles only have radar sensors around the vehicle body. After the radar collected signals are processed, an audible and visual prompt signal is sent without brake intervention. This makes the parking operation still a must for the driver. problems faced. [0003] In addition, eve...
