Embodiment 1

[0034] figure 1 It is a flow chart of a driving assistance system control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the driver controls the driving assistance system in stages when the driver leaves the steering wheel. This method can be executed by the driving assistance system. The assisted driving system can be implemented by software and / or hardware, and the assisted driving system can be configured on a computing device, specifically including the following steps:

[0035] Step 11, obtaining the driver's hand position information;

[0036] Among them, the driver's hand position information can be understood as the positional relationship between the driver's hands and the steering wheel, including both hands leaving the steering wheel and hands not leaving the steering wheel.

[0037] Specifically, the assisted driving system obtains the driver's hand position information through sensors to determine wh...

Embodiment 2

[0048] figure 2It is a flow chart of a control method for a driving assistance system provided by Embodiment 2 of the present invention. The technical solution of this embodiment is further refined on the basis of the above-mentioned technical solution, specifically including the following steps:

[0049] Step 21. According to the torque data information sent by the torque sensor, it is judged whether the driver's hands are all off the steering wheel.

[0050] Among them, the torque sensor can be understood as a detection component used to sense the torsional torque on various rotating or non-rotating mechanical parts by converting the physical change of the torque into a precise electrical signal.

[0051] Specifically, the assisted driving system acquires the torque data information sent by the torque sensor, and when the torque data information is within the preset threshold range, it is considered that the driver's hands are on the steering wheel; otherwise, it is consid...

Embodiment 3

[0095] Figure 7 It is a schematic structural diagram of an assisted driving system provided by Embodiment 3 of the present invention. The assisted driving system includes: a position state acquisition module 31 , a danger level determination module 32 and an alarm response execution module 33 .

[0096] Wherein, the position state acquisition module 31 is used to obtain the driver's hand position state information; the danger level determination module 32 is used to determine the driving danger level according to the hand position state information; the alarm response execution module 33 is used to If the above-mentioned driving risk level reaches the high risk level, the control executes the corresponding super-level alarm response.

[0097] The technical solution of this embodiment solves dangerous situations such as untimely braking caused by the driver leaving the steering wheel with both hands for a long time and cannot handle emergency conditions, and when the driver le...

Abstract

The invention discloses an auxiliary driving system control method, an auxiliary driving system, a vehicle and a storage medium. The method comprises the following steps: acquiring hand position stateinformation of a driver; determining a driving danger level according to the hand position state information; and if the driving danger level reaches the high danger level, controlling to execute a corresponding special-level alarm response. Dangerous situations such as untimely braking caused by the fact that the hands of the driver leave a steering wheel for a long time and cannot deal with emergency conditions are avoided, the purpose that when the two hands of the driver leave the steering wheel, danger reminding is conducted on the driver by stages through the auxiliary driving system, and the vehicle is controlled is achieved, and the safety of the auxiliary driving system is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle assisted driving, and in particular, to a control method for a assisted driving system, a assisted driving system, a vehicle, and a storage medium. Background technique [0002] With the continuous advancement of automobile intelligence, the assisted driving function is playing an increasingly important role in the driving process. The function of the assisted driving system can assist the driver to control the steering wheel to keep the vehicle in the middle of the lane and in the driving direction during driving. It can control the speed of the vehicle, which liberates the driver's feet and hands to a certain extent. [0003] However, due to the complexity of the scene, sensor defects and technical level, the assisted driving function still cannot guarantee 100% safety, and the driver's hands leaving the steering wheel for a long time will cause a huge safety hazard. A...
