The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
The embodiment of the invention provides a steering control method based on automatic driving, which is suitable for the situations that the target steering angle of a vehicle is adjusted before and during steering and the steering is controlled according to the adjusted target steering angle. Fig. 1 is a flowchart of an automatic driving-based steering control method, which is executed by an electronic device and includes:
and S110, when the distance from the steering position is set to be the length, determining a first target steering angle according to the path planning and the environment perception.
The steering position is a position where steering is required, i.e. a critical position from straight to steering, for example at an intersection. The embodiment is not limited to a specific value of the set length, and may be set according to practical situations, for example, 30 meters. Preferably, the set length is determined according to the vehicle speed, the vehicle position, and the steering-permitted lane width so that the vehicle travels to the steering-permitted lane edge (the reverse direction side of steering) at the arrival steering position. The lane width that allows steering is the total width of at least one lane.
Fig. 2 is a schematic diagram of a driving route of the vehicle according to an embodiment of the present invention. Assuming that the vehicle speed is 30km/h, the number of lanes allowing steering is 2, the total width is 3m, the vehicle needs to travel transversely for 1 meter from the vehicle position to the edge of the lane, and the transverse vehicle speed is 0.5m/s, the vehicle is 16.6m at a distance of 30km/h over 2s, and the set length is set.
The path planning defines a specific travel route for a lane-level path from a departure point to a destination. The environment sensing comprises the front road condition sensed based on the collected data of cameras, radars and the like, whether obstacles exist or not, whether the front vehicle is braked and needs to avoid or not, and the like. Whether the host vehicle needs to turn (to avoid an obstacle or a lead vehicle) and a first target steering angle can be determined based on environmental awareness on the basis of path planning. The specific method for determining the first target steering angle can be determined based on the speed of the vehicle and the road condition, and the prior art is referred to.
For convenience of description and distinction, the target steering angle obtained when the length is set from the steering position is referred to as a first target steering angle. The steering angle may be defined as the angle at which the front wheel turns relative to straight.
S120, judging whether the vehicle is at unstable risk or not according to the running state of the vehicle and the first target steering angle. If so, jump to S121; if not, go to S122.
The running state of the vehicle comprises a dynamic state and a static state, wherein the static state comprises a front wheel positioning parameter, a rear suspension structure parameter and the like. The dynamic state is a state in the running process, including the speed of the vehicle and the like.
First, a roll angle is predicted from the host vehicle running state and the first target steering angle. Specifically, the running state, the steering angle and the actually measured roll angle of the vehicle in the running process of the vehicle are collected in advance, and a corresponding relation is established; and predicting the roll angle according to the running state of the vehicle, the first target steering angle and the corresponding relation. Wherein, the corresponding relation can be a one-to-one corresponding table of data, and the roll angle is predicted by looking up a table; the roll angle may be predicted by solving a mathematical expression in which the running state and the steering angle of the vehicle are input and the actual measured roll angle is output.
Then, if the predicted roll angle is larger than the maximum roll stabilizing angle, judging that the vehicle has unstable risk; and if the predicted roll angle is smaller than or equal to the maximum roll stability angle, judging that the vehicle has no unstable risk. Wherein the maximum roll stability angle visually reflects the roll stability performance of the host vehicle, and the specific acquisition method is referred to the prior art.
S121, controlling the vehicle to travel the set length in the reverse direction of steering. Execution continues with S130.
And if the vehicle turns right, controlling the vehicle to run left for the set length, and if the vehicle turns left, controlling the vehicle to run right for the set length.
S122, controlling the steering of the vehicle at the first target steering angle, and ending the operation.
S130, at the position of reaching the steering position, determining a second target steering angle again according to the path planning and the environment perception.
For example, at an intersection where the host vehicle has changed lanes or is leaning towards the lane edges without changing lanes, there may be a change in the forward view of obstacles or vehicles ahead, requiring a re-determination of the second target steering angle based on path planning and environmental awareness.
It is foreseen that the second target steering angle is smaller than the first target steering angle as the host vehicle travels away from the steering direction.
For convenience of description and distinction, the target steering angle obtained at the steering position is referred to as a second target steering angle.
And S140, judging whether the vehicle is at unstable risk or not according to the running state of the vehicle and the second target steering angle. If not, S141 is performed. If so, S142 is performed.
Similar to S120, the roll angle is first predicted from the host vehicle running state and the second target steering angle. Specifically, the running state, the steering angle and the actually measured roll angle of the vehicle in the running process of the vehicle are collected in advance, and a corresponding relation is established; and predicting the roll angle according to the driving state of the vehicle, the second target steering angle and the corresponding relation. Then, if the predicted roll angle is larger than the maximum roll stabilizing angle, judging that the vehicle has unstable risk; and if the predicted roll angle is smaller than or equal to the maximum roll stability angle, judging that the vehicle has no unstable risk.
S141, controlling the steering of the vehicle at the second target steering angle.
S142, the speed of the vehicle is reduced to be a set value, so that the vehicle is free from unstable risk when steering at the second target steering angle.
Specifically, on the basis of the corresponding relation, determining the maximum speed of the host vehicle when the maximum stable roll angle is reached according to the corresponding relation, the host vehicle state and the second target steering angle, and taking the maximum speed as the set value; the speed of the vehicle is reduced to be a set value.
And inputting the maximum stable rolling, the state of the vehicle and the second target steering angle into a corresponding relation, and solving to obtain the maximum speed of the vehicle. It can be seen that after the speed of the vehicle is reduced to the set value, the vehicle can be steered at the second target steering angle, so that the vehicle is ensured not to turn on one's side.
According to the invention, when the length is set from the steering position, the first target steering angle is determined in advance, and further, when the steering instability is predicted, a certain distance margin exists, and the steering device can drive for a certain distance in the reverse direction of steering, so that the required target steering angle, namely a commonly-called turning large bend, can be reduced. Compared with the prior art, the method reduces the steering angle to improve the stability, but changes the path in advance, and determines the second target steering angle on the new path, so that the smaller steering angle can also successfully steer.
On the basis of the above embodiment, considering that the predicted roll angle may be different from the actual roll angle detected, it is still necessary to detect whether there is an unstable risk during running and make corresponding adjustments. If the speed of the vehicle is reduced to the set value, and the instability risk of the vehicle is detected in the running process when the vehicle is steered at a second target steering angle, the second target steering angle is reduced.
Specifically, the roll angle is actually detected when steering at the second target steering angle, and the second target steering angle is reduced when a risk of rollover is identified. The magnitude of the decrease may be a set point or a gradual decrease to avoid rollover.
Preferably, the method further includes, after reducing the second target steering angle: and if the steering cannot be successfully performed according to the environment sensing judgment, controlling the braking of the vehicle. The front lane line can be detected according to the data of the camera and the radar, and then the curvature of the road is obtained. And then judging whether the road passing through the curvature can be judged by combining the current pose and the steering angle of the vehicle. If the steering is not successful, the braking of the vehicle is controlled and the vehicle is transmitted to the driver for operation. If the steering can be achieved, the steering of the vehicle is continuously controlled at the reduced steering angle.
In the above embodiments, the host vehicle is equipped with the steer-by-wire system to ensure steering accuracy.
