Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of embodiments of the present disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart illustrating a vehicle control method according to an embodiment of the present disclosure, including:
s110, responding to the detection that a steer-by-wire system of the vehicle is invalid, and prompting a driver to take over the vehicle within a first preset time;
s120, monitoring the speed of the vehicle within a second preset time under the condition that the driver successfully takes over the vehicle;
and S130, under the condition that the speed of the vehicle is not reduced to the first preset speed within the second preset time, stopping taking over by the driver and controlling the speed of the vehicle to be reduced to the second preset speed.
The first preset speed is a safe speed which needs to be reached by the vehicle within a second preset time after the driver takes over the vehicle under the condition that the vehicle determines that the steer-by-wire system is invalid, and can be 0 or other speeds used for determining that the driver completes effective braking on the vehicle speed. For example, the first preset speed may be preset according to the second preset time. The second preset speed may be the same as the first preset speed, or may be specifically configured according to actual requirements, which is not limited herein. If the speed of the vehicle is not reduced to the first preset speed within the second preset time, the fact that the driver does not properly process the current situation is proved, and in order to guarantee driving safety, the driver is stopped taking over and replacing the vehicle to control the reduction of the speed of the vehicle.
By adopting the method of the embodiment, when the failure of the steer-by-wire system of the vehicle is detected, the priority is given to the condition that the driver takes over rather than directly controlling the deceleration by the vehicle, so that the function loss of the vehicle part can be reduced. Meanwhile, under the condition that the driver takes over, the safe speed which the driver needs to control the vehicle to reach is set in a specific time, the driving condition after the driver takes over is detected, the driver takes over is stopped under the condition that the driver does not control the vehicle to reach the safe speed, the vehicle controls the speed to be reduced, and the driving safety is guaranteed.
Further, as shown in fig. 2, the vehicle control method further includes:
and S210, controlling the speed of the vehicle to be reduced to a second preset speed under the condition that the driver fails to take over the vehicle.
It will be appreciated that in the event of a detected failure of the steer-by-wire system of the vehicle, the driver is given priority over taking over, but if the driver fails to take over the vehicle within the first predetermined time, the vehicle itself controls the speed reduction of the vehicle for driving safety reasons.
Illustratively, as shown in fig. 3, the specific steps of the vehicle controlling the vehicle to decelerate to the second preset speed include:
s310, controlling the deceleration of the vehicle to reach the first preset deceleration within the third preset time;
s320, controlling the deceleration of the vehicle to increase from the first preset deceleration to the second preset deceleration within the fourth preset time;
and S330, controlling the vehicle to maintain the second preset deceleration until the speed of the vehicle is reduced to the second preset speed.
The steps S310, S320, and S330 are three stages of controlling the vehicle to decelerate, respectively, in the first stage, the deceleration of the vehicle is controlled to reach the first preset deceleration within the third preset time, and the variation value of the vehicle deceleration per unit time in this stage is the maximum value in the three stages, so that on one hand, after the steer-by-wire system fails, the vehicle can be quickly braked to ensure driving safety, and on the other hand, a warning effect can be provided for a driver who has failed to take over the vehicle within the first preset time before, so as to ensure that the driver is aware of the failure of the steer-by-wire system.
In the second stage, the deceleration of the vehicle is controlled to be increased from the first preset deceleration to a second preset deceleration within a fourth preset time, and the second preset deceleration is the maximum deceleration which can be reached by the vehicle under the condition of ensuring the safety. And after the second preset deceleration is reached, entering a third stage, and maintaining the second preset deceleration until the speed of the vehicle is reduced to a second preset speed.
It is understood that the above three stages of the vehicle controlling the self-deceleration are the configuration in which the original vehicle speed is in the ideal interval, and depending on the speed in the actual driving situation, there may be a case where the vehicle does not reach the maximum deceleration (the first stage or the second stage) but the speed of the vehicle has decreased to the second preset speed, in which case, whether in the first stage or the second stage, if the speed of the vehicle has decreased to the second preset speed, it is regarded that the process of the vehicle controlling the self-deceleration has been completed, and the vehicle does not mechanically perform the three stages of controlling the self-deceleration.
By adopting the method of the embodiment, under the condition that the driver cannot take over the vehicle or the driver takes over the vehicle to terminate, the vehicle controls the speed of the vehicle to be reduced in stages until the speed of the vehicle is reduced to the safe speed, the loss of parts of the vehicle in the speed reduction process can be reduced as much as possible on the premise of ensuring the driving safety, the effect of degrading the whole vehicle is achieved, meanwhile, the effect of bad experience of the driver and passengers due to the fact that the driver and the passengers take the vehicle when the vehicle is braked suddenly is avoided by controlling the speed of the vehicle in stages, and the safety problem of the driver and the passengers due to the fact that the driver and the passengers brake suddenly is avoided further.
Optionally, as shown in fig. 4, the vehicle control method further includes:
and S410, in response to the condition that the duration of the pressure applied to the brake pedal of the vehicle is not less than the fifth preset time, determining that the driver successfully takes over the vehicle.
It will be appreciated that in the event that the vehicle prompts the driver to take over the vehicle for a first predetermined time, the effect of a false touch on the take-over event needs to be taken into account. The method can be configured in the situation that the line control steering system fails, the driver takes over the operation of the vehicle to step on the brake pedal, and if the duration that the pressure is applied to the brake pedal of the vehicle is detected to be not less than the fifth preset time, the driver can be determined to receive the taking over prompt of the vehicle and be ready to take over the vehicle.
Further, the means for preventing the impact of the accidental touch on the take-over event may also set a threshold value for the pressure applied to the brake pedal (the intention of the driver to take over is determined only in the case where the pressure applied to the brake pedal by the driver is greater than the threshold value), and the like, and is not particularly limited herein.
By adopting the method of the embodiment, after the driver is informed to take over the vehicle, the condition for determining the successful taking over of the vehicle by the driver is set, so that the influence of mistaken touch on the taking over event is avoided, the processing of the vehicle to the failure of the steer-by-wire system is prevented from being delayed under the condition that the driver cannot take over the vehicle, and the driving safety of the steer-by-wire system vehicle is further ensured.
For example, the vehicle does not respond to requests from the accelerator pedal and the brake pedal in controlling the vehicle to decelerate to a second preset speed.
It can be understood that, in order to ensure the smooth progress of the deceleration process of the vehicle control itself, the vehicle does not respond to the acceleration and deceleration request of the vehicle by the driver in this stage. However, the vehicle does not respond to the request and does not mean that the vehicle stops detecting the behavior of the driver, the driver can still express an intention by operating the accelerator pedal and the brake pedal, for example, the driver fails to receive a take-over prompt of the vehicle and successfully takes over the vehicle for objective or subjective reasons within a first preset time, but is aware of a failure condition of the steer-by-wire system in the deceleration process of the vehicle control self (for example, the vehicle rapidly brakes the vehicle itself in the first stage of the deceleration of the vehicle control self to a second preset speed and carries out secondary prompt on the driver), the driver can still apply pressure on the brake pedal for a duration not less than a fifth preset time to express a driving intention to the vehicle, and the vehicle can transfer the vehicle control right to the driver after controlling the vehicle to decelerate to the second preset speed.
Illustratively, in another specific example of the present application, the controller for implementing the three stages of the self-controlled deceleration in the vehicle in the above-described steps S310 to S330 is different from the controller for supporting the driver to control the deceleration of the vehicle through the brake pedal. In this case, in the above steps S120 and S130, a third preset speed, which is greater than the first preset speed and is also used for monitoring the speed of the vehicle in step S120, may be set.
It can be understood that if the initial speed of the vehicle is high when the steer-by-wire system fails, there are situations where it is difficult for the driver to reduce the speed of the vehicle to the first preset speed within the second preset time. If the driver does not successfully reduce the speed of the vehicle to the first preset speed within the second preset time when taking over the vehicle, but the requirement that the speed of the vehicle is reduced to the third preset speed or below is met, the driver can be considered to perform an operation behavior with a certain control effect on the vehicle under the condition that the online control steering system fails, in order to ensure driving safety, the vehicle can send a request for controlling the self-deceleration without stopping taking over of the driver (namely continuously responding to the request of the brake pedal), and then the driver can realize double deceleration of deceleration controlled by the brake pedal and self-deceleration controlled by the vehicle, so that the vehicle can be decelerated more efficiently under emergency conditions.
By adopting the method of the embodiment, the process of controlling the vehicle to decelerate can be prevented from being interfered by the behavior of the driver, and the driving safety under the condition that the steer-by-wire system is invalid is further ensured.
The specific arrangements and implementations of the embodiments of the present application have been described above from various perspectives. By using the method provided by the embodiment, under the condition that the failure of the steer-by-wire system of the vehicle is detected, the condition that the driver takes over is preferentially considered, and the processing strategy that the vehicle controls the speed reduction under the condition that the driver fails to take over or the processing strategy that the vehicle controls the speed reduction under the condition that the processing is improper after taking over is taken over, so that the loss of the parts of the vehicle is reduced as much as possible under the condition that the driving safety is ensured, and the effect of degrading the whole vehicle is achieved.
As implementations of the above methods, embodiments of the present disclosure also provide a vehicle control device.

and the control module 530 is used for terminating the driver taking over and controlling the speed of the vehicle to be reduced to the second preset speed in the case that the speed of the vehicle is not reduced to the first preset speed within the second preset time.

in the event that the driver fails to take over the vehicle, the speed of the vehicle is controlled to decrease to a second preset speed.
