Detailed Description
The embodiment of the invention provides a vehicle steering service calling method and device, and solves the technical problem of widening the steering service application scene on the premise of ensuring the vehicle safety.
In order to better understand the technical scheme of the invention, the technical scheme of the invention is described in detail in the following with the accompanying drawings and specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
As shown in fig. 1, the vehicle steering service invoking method includes:
step S1, after receiving the call request of the vehicle steering service, determining the request source of the call request;
step S2, if the request source of the calling request is outside the scope of the name list of the preset request source, the speed and the driving state of the vehicle are obtained, the steering request direction corresponding to the calling request is determined, and whether an obstacle exists in the steering area corresponding to the steering request direction is judged;
step S3, if the vehicle speed is lower than the preset speed threshold value, the driving state meets the preset conditions, and no obstacle exists in the steering area, the requested steering torque value of the calling request is obtained;
step S4, determining a steering torque execution value from the requested steering torque value;
in step S5, a steering service is executed based on the steering request direction and the steering torque execution value.
In step S2, the request source included in the preset request source list belongs to a request source trusted by the vehicle, and generally refers to a request source before the vehicle is not opened to the third-party development platform after the vehicle volume is produced, and has been granted the authority to invoke the steering service. For the steering service, the request sources in the preset request source list may include a steering wheel, steering of the intelligent driving system, and the like. After a request source in the preset request source list sends a request for calling the steering service, the steering service is executed immediately, and the safety of the vehicle or the will of the vehicle owner is not influenced. If the request source of the steering service invoking request is out of the range of the preset request source name list, the representative request source is third-party application software, and whether the vehicle safety is affected after the steering service is executed needs to be considered.
It can be understood that, when the vehicle speed is too high or the vehicle is accelerating, the third-party application software is allowed to call the steering service, and further the control of the vehicle steering may cause the vehicle to turn over, which affects the vehicle safety. When the vehicle speed is higher than the preset speed threshold value, the vehicle speed is over-large, and the preset speed threshold value can be 40 km/h. The preset condition does not include that the vehicle is running with acceleration.
The steering request direction corresponding to the steering service invoking request is left-turn or right-turn, the steering area is an area through which the vehicle passes from the beginning of steering to the end of steering, and comprises a certain area at the side of the vehicle and a certain area at the rear side, the obstacles at the side of the vehicle are mainly pedestrians and vehicles in adjacent lanes, and the obstacles at the rear side are mainly coming vehicles behind the adjacent lanes. It can be understood that when there is an obstacle such as a pedestrian or a vehicle in the steering area, allowing the third-party application software to invoke the steering service, and further controlling the vehicle to steer may cause the vehicle to collide with the obstacle, affecting the vehicle safety, so that the third-party application software is prohibited from invoking the steering service when there is an obstacle in the steering area corresponding to the steering request direction in the embodiment.
In step S3, the steering torque request value is the steering torque that the third party application software requests the vehicle to follow. In step S4, the principle of determining the steering torque execution value based on the requested steering torque value is: the vehicle safety is not affected after the steering service is performed based on the steering torque execution value. In this way, after the step S5 executes the steering service based on the steering request direction and the steering torque execution value, the third-party application software can call the steering service on the premise of ensuring the safety of the vehicle, thereby widening the application scenario of the steering service.
In step S3, the preset condition may include that the vehicle is running at a constant speed, and the steering based on the steering torque execution value does not affect the safety of the vehicle when the vehicle is running at a low speed and a constant speed, and the third-party application software may be allowed to invoke the steering service based on the steering torque execution value. When the vehicle runs at a reduced speed, steering during the reduction may cause vehicle instability, which may affect vehicle safety, and for safety, it may be considered that third-party application software is prohibited from invoking a steering service, but an application scenario of the steering service is limited. It is understood that there is a safety risk that the vehicle turns when the deceleration is large, and that the vehicle does not affect the vehicle safety when the vehicle is running at a low deceleration and the turning is performed based on the steering torque execution value when the deceleration is small. For this reason, the preset condition may further include that the vehicle is in deceleration running and the current deceleration is lower than a preset deceleration threshold, the current deceleration is lower than the preset deceleration threshold, it represents that the current deceleration of the vehicle is small, and the third-party application software is allowed to invoke the steering service based on the steering torque execution value without affecting the vehicle safety, so that when the vehicle is in deceleration running and the current deceleration is small, the third-party application software is allowed to invoke the steering service based on the steering torque execution value, which may further widen the application scenario of the steering service.
As can be seen from the above, the method for invoking the vehicle steering service according to the embodiment determines a request source of the invocation request after receiving the invocation request of the vehicle steering service, if the request source of the invocation request is outside the scope of the preset request source name, represents that the request source is the third-party application software, and it needs to consider whether the vehicle safety is affected after the steering service is executed, when the vehicle speed is lower than the preset speed threshold, the driving state meets the preset condition, and there is no obstacle in the steering area, the steering torque execution value is determined according to the steering torque request value, the steering service is executed based on the steering request direction and the steering torque execution value, which is equivalent to allowing the third-party application software to invoke the steering service based on the steering torque execution value on the premise that the vehicle safety is not affected by the vehicle steering, thereby widening the application scenario of the vehicle steering service.
Step S4 of this embodiment may specifically include: and if the requested steering torque value is lower than a preset torque threshold value corresponding to the vehicle speed, determining the requested steering torque value as a steering torque execution value. The preset torque threshold corresponding to the current vehicle speed is a safe torque for ensuring that the vehicle does not turn over at the current vehicle speed, and the larger the vehicle speed is, the smaller the corresponding preset torque threshold should be. The preset torque threshold value corresponding to the vehicle speed of 40km/h can be 4 N.M. It is understood that if the requested steering torque value is higher than the preset torque threshold corresponding to the current vehicle speed, controlling the vehicle to steer based on the requested steering torque value may cause the vehicle to roll over; if the requested steering torque value is lower than the preset torque threshold value corresponding to the current vehicle speed, the vehicle is controlled to steer based on the requested steering torque value, so that the vehicle cannot turn over, and the safety of the vehicle cannot be influenced.
In the embodiment, in consideration of improving the vehicle safety, the third-party application software may be prohibited from invoking the steering service when the requested steering torque value is higher than the preset torque threshold corresponding to the current vehicle speed, so that although the vehicle safety is improved, the application scenario of the steering service is also limited. For this reason, in this embodiment, step S4 preferably further includes:
and if the steering torque request value is higher than a preset torque threshold value corresponding to the vehicle speed, determining the preset torque threshold value as a steering torque execution value.
When the steering torque request value is higher than the preset torque threshold value corresponding to the vehicle speed, the third-party application software is allowed to call the steering service based on the steering torque request value, which may cause the vehicle to turn on one side, but the third-party application software is allowed to call the steering service based on the preset torque threshold value, which may not cause the vehicle to turn on one side, does not affect the vehicle safety, and can further widen the application scene of the vehicle steering service on the premise of ensuring the vehicle safety. Here, although the vehicle safety is ensured, the steering service is not completely performed according to the steering torque request value requested by the third party application software, and the request of the third party application software is not completely satisfied.
As shown in fig. 2, the present embodiment further provides a vehicle steering service invoking device, including:
the request source determining module is used for determining a request source of a calling request after receiving the calling request of the vehicle steering service;
the data processing module is used for acquiring the speed and the running state of the vehicle if the request source of the calling request is out of the range of the preset request source name list, determining the steering request direction corresponding to the calling request and judging whether an obstacle exists in the steering area corresponding to the steering request direction;
the request value acquisition module is used for acquiring a request value of the steering torque of the calling request if the vehicle speed is lower than a preset speed threshold value, the driving state meets a preset condition and no obstacle exists in a steering area;
an execution value determination module for determining a steering torque execution value based on the requested steering torque value;
and the steering service execution module is used for executing the steering service based on the steering request direction and the steering torque execution value.
The preset request source list comprises request sources which belong to vehicle trust request sources, generally refers to the request sources before the vehicle is opened to the third-party development platform after the vehicle is produced, and the request sources are granted with the authority of invoking the steering service. For the steering service, the request sources in the preset request source list may include a steering wheel, steering of the intelligent driving system, and the like. After a request source in the preset request source list sends a steering service calling request, the steering service is immediately executed, and the safety of the vehicle or the intention of the vehicle owner is not influenced. If the request source of the steering service call request is out of the range of the preset request source name list, the request source is represented by third-party application software, and whether the vehicle safety is influenced after the steering service is executed needs to be considered.
It can be understood that, when the vehicle speed is too high or the vehicle is accelerating, the third-party application software is allowed to call the steering service, and further the control of the vehicle steering may cause the vehicle to turn over, which affects the vehicle safety. When the vehicle speed is higher than the preset speed threshold value, the vehicle speed is over-large, and the preset speed threshold value can be 40 km/h. The preset condition does not include that the vehicle is running with acceleration.
The steering request direction corresponding to the steering service invoking request is left-turn or right-turn, the steering area is an area through which the vehicle passes from the beginning of steering to the end of steering, and comprises a certain area at the side of the vehicle and a certain area at the rear side, the obstacles at the side of the vehicle are mainly pedestrians and vehicles in adjacent lanes, and the obstacles at the rear side are mainly coming vehicles behind the adjacent lanes. It can be understood that when there is an obstacle such as a pedestrian or a vehicle in the steering area, allowing the third-party application software to invoke the steering service, and further controlling the vehicle to steer may cause the vehicle to collide with the obstacle, affecting the vehicle safety, so that the third-party application software is prohibited from invoking the steering service when there is an obstacle in the steering area corresponding to the steering request direction in the embodiment.
The steering torque request value is a steering torque that the third party application software requests the vehicle to follow. The principle that the execution value determining module determines the steering torque execution value according to the steering torque request value is as follows: the vehicle safety is not affected after the steering service is performed based on the steering torque execution value. Therefore, after the steering service execution module executes the steering service based on the steering request direction and the steering torque execution value, the third-party application software can call the steering service on the premise of ensuring the safety of the vehicle, and the application scene of the steering service is widened.
The preset conditions may include that the vehicle is running at a constant speed, steering based on the steering torque execution value does not affect the safety of the vehicle when the vehicle is running at a low speed and a constant speed, and the third-party application software may be allowed to invoke the steering service based on the steering torque execution value. When the vehicle runs at a reduced speed, steering during the reduction may cause vehicle instability, which may affect vehicle safety, and for safety, it may be considered that third-party application software is prohibited from invoking a steering service, but an application scenario of the steering service is limited. It is understood that there is a safety risk that the vehicle turns when the deceleration is large, and that the vehicle does not affect the vehicle safety when the vehicle is running at a low deceleration and the turning is performed based on the steering torque execution value when the deceleration is small. For this reason, the preset condition may further include that the vehicle is in deceleration running and the current deceleration is lower than a preset deceleration threshold, the current deceleration is lower than the preset deceleration threshold, it represents that the current deceleration of the vehicle is small, and the third-party application software is allowed to invoke the steering service based on the steering torque execution value without affecting the vehicle safety, so that when the vehicle is in deceleration running and the current deceleration is small, the third-party application software is allowed to invoke the steering service based on the steering torque execution value, which may further widen the application scenario of the steering service.
As can be seen from the above, the vehicle steering service invoking device of this embodiment determines a request source of the invocation request after receiving the invocation request of the vehicle steering service, if the request source of the invocation request is outside the scope of the preset request source name, the request source is represented by third-party application software, and it needs to be considered whether the vehicle safety is affected after the steering service is executed, when the vehicle speed is lower than the preset speed threshold, the driving state meets the preset condition, and there is no obstacle in the steering area, the steering torque execution value is determined according to the steering torque request value, the steering service is executed based on the steering request direction and the steering torque execution value, which is equivalent to allowing the third-party application software to invoke the steering service based on the steering torque execution value on the premise that the vehicle steering does not affect the vehicle safety, thereby widening the application scenario of the vehicle steering service.
Further, the execution value determination module is further configured to: and if the requested steering torque value is lower than a preset torque threshold value corresponding to the vehicle speed, determining the requested steering torque value as a steering torque execution value.
The preset torque threshold corresponding to the current vehicle speed is a safe torque for ensuring that the vehicle does not turn over at the current vehicle speed, and the larger the vehicle speed is, the smaller the corresponding preset torque threshold should be. The preset torque threshold value corresponding to the vehicle speed of 40km/h can be 4 N.M. It can be understood that if the requested steering torque value is higher than the preset torque threshold corresponding to the current vehicle speed, controlling the vehicle to steer based on the requested steering torque value may cause the vehicle to roll over; if the requested steering torque value is lower than the preset torque threshold value corresponding to the current vehicle speed, the vehicle is controlled to steer based on the requested steering torque value, so that the vehicle cannot turn over, and the safety of the vehicle cannot be influenced.
In the embodiment, in consideration of improving the vehicle safety, the third-party application software may be prohibited from invoking the steering service when the requested steering torque value is higher than the preset torque threshold corresponding to the current vehicle speed, so that although the vehicle safety is improved, the application scenario of the steering service is also limited. For this reason, the present embodiment preferably executes the value determining module, and is further configured to:
and if the steering torque request value is higher than a preset torque threshold value corresponding to the vehicle speed, determining the preset torque threshold value as a steering torque execution value.
When the steering torque request value is higher than the preset torque threshold value corresponding to the vehicle speed, the third-party application software is allowed to call the steering service based on the steering torque request value, which may cause the vehicle to turn on one side, but the third-party application software is allowed to call the steering service based on the preset torque threshold value, which may not cause the vehicle to turn on one side, does not affect the vehicle safety, and can further widen the application scene of the vehicle steering service on the premise of ensuring the vehicle safety. Here, although the vehicle safety is ensured, the steering service is not completely performed according to the steering torque request value requested by the third party application software, and the request of the third party application software is not completely satisfied.

The electronic device of the embodiment determines a request source of a call request after receiving the call request of the vehicle steering service, if the request source of the call request is outside a preset request source name list range, the request source is third-party application software, and whether the vehicle safety is affected after the steering service is executed needs to be considered, when the vehicle speed is lower than a preset speed threshold value, the driving state meets preset conditions, and no obstacle exists in a steering area, a steering torque execution value is determined according to the steering torque request value, the steering service is executed based on the steering request direction and the steering torque execution value, which is equivalent to allowing the third-party application software to call the steering service based on the steering torque execution value on the premise that the vehicle safety is not affected by the vehicle steering, and the application scene of the vehicle steering service is widened.
