Problems solved by technology

[0004] 1. There is a lack of necessary monitoring or effective evaluation of the current driver's state. When encountering a collision risk, the driver may avoid and trigger AEB, causing the driver to complain about the premature triggering of the AEB system or the driver lightly stepping on the brake After the AEB started too late, even if the brakes are fully applied, collision avoidance will inevitably occur
[0005] 2. The sensitivity cannot be automatically adjusted according to the driver's actual driving state and driving speed. Some people may mistakenly trigger AEB when changing lanes due to emergencies or overtaking in more intense driving. When AEB is triggered, it will produce relatively strong braking, which will affect the driving experience. , may also cause a rear-end collision or a risk of loss of control of the vehicle

Embodiment Construction

[0018] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings, and the embodiments of the present invention include but are not limited to the following embodiments.

[0019] see figure 1 , in this embodiment, the vehicle AEB control method combined with the driver state includes the following steps:

[0020] S1. According to the driving information such as the vehicle speed, steering wheel angle, turn signal, brake, accelerator, yaw rate, etc., determine the driver's driving activity level HVS-L, and then execute S2.

[0021] Among them, the determination method of activity level HVS-L is based on the real-time calculation method. It is preferable that the safety target distance between the preset vehicle AEB brake and the vehicle in front is 1m, and the vehicle speed, steering wheel angle, turn signal, Braking, accelerator, yaw rate and other driving information set 8 parameter thresholds and a relativ...

Abstract

The invention discloses a vehicle automatic emergency braking control method and system combined with a driver state and a computer readable storage medium, and the method comprises the steps: S1, according to driving information such as the vehicle speed, the steering wheel turning angle, the steering lamp, the brake, the accelerator and the yaw velocity of vehicle driving, judging the vehicle driving activeness level HVS-L of a driver; and S2, automatically adjusting the sensitivity of the AEB system according to the activity level HVS-L. On the premise that driver monitoring equipment is not introduced, the low-cost method is used for improving the driving experience of a driver during normal driving and the driving safety of the driver when the driver is inattention.

Description

technical field [0001] The invention belongs to the technical field of automatic emergency braking of intelligent driving vehicles, and in particular relates to a method and a system for controlling vehicle dynamics combined with a driver. Background technique [0002] Automatic Brake Assist (AEB) is widely used in vehicles in the field of intelligent driving. The basic working principle of the AEB system is: the AEB system initially sets a certain safe braking distance, and the AEB system uses sensors such as radar or camera to measure the distance to the vehicle in front in real time, and then calculates the distance to the target according to the known driving speed of the vehicle. Based on the relative speed of driving, the collision time T0 with a safe distance is obtained; compared with the time T1 required to avoid collision with a certain slope and acceleration braking, if T1 is less than or equal to T0 and the driver does not have time to step on the brake pedal Wh...
