Claims (7)

1. 1. The auxiliary vehicle escape method is characterized by comprising the following steps of: S1, monitoring the running state of a vehicle in real time; s2, judging whether the vehicle is in a slipping state, if so, carrying out the next step, and if not, returning to the step S1; s3, the driver judges the getting-out position and marks the getting-out position on a control system of the vehicle; S4, the control system prompts a driver to rotate the steering wheel within a set angle range, and the driver controls the vehicle to back and advance within a set distance until the vehicle moves to the escaping position; s5, the control system controls the vehicle to run at a set speed at a constant speed, and the escape is completed; An alarm system is arranged in a cab of the vehicle and is in communication connection with the control system, and when the vehicle is judged to be in a slipping state, the alarm system alarms to prompt a driver; In the step S4, when the vehicle advances to a set distance, the control system prompts the driver to brake through the alarm system; In the step S4, when the vehicle backs up to a set distance, the control system prompts the driver to brake through the alarm system.
2. 2. The method according to claim 1, wherein in the step S2, the vehicle is regarded as being in a slip state when a difference between a running speed of the vehicle and a vehicle speed corresponding to a rotation speed of the driving wheel is within a set difference range.
3. 3. A vehicle-assisted escape method according to claim 2, characterized in that the rotational speed of the driving wheel is detected by means of a speed sensor provided in the vehicle.
4. 4. The vehicle-assisted escape method of claim 2 wherein said set differential range is calibrated.
5. 5. The vehicle-assisted escape method of claim 1, wherein the alarm system comprises a voice broadcast system, a light prompting system and/or a text prompting system.
6. 6. The method according to claim 1, wherein in the step S4, the control system prompts the driver through the alarm system when the angle of the driver turning the steering wheel is not within the set angle range.
7. 7. A vehicle comprising a control system that employs the vehicle-assisted escape method of any one of claims 1-6 to assist in escaping a vehicle.

Description

Vehicle auxiliary escaping method and vehicle Technical Field The invention relates to the technical field of vehicle control, in particular to a vehicle auxiliary escaping method and a vehicle. Background With the development of the automobile industry, more and more automobiles enter the production and living fields, and great convenience is provided for people's traffic. However, when the vehicle runs on a muddy road in the countryside in overcast and rainy weather, the vehicle tends to sink into the muddy road easily, and the phenomenon of wheel slip occurs, so that most people can increase the accelerator according to inertial operation at this time, and the rotation speed of the wheels is increased to try to get rid of poverty. However, the wheel rotates too fast, and ground attachments (soil, sand and the like) which originally bear the weight and friction force of the wheel are thrown out, so that the wheel may become deeper, and meanwhile, more silt is attached to gaps of the wheel, so that the friction coefficient is reduced, and the difficulty of vehicle escape is increased. Therefore, a vehicle auxiliary escape method and a vehicle are needed to solve the above technical problems. Disclosure of Invention The invention aims to provide a vehicle auxiliary getting rid of poverty method and a vehicle, which can assist a driver to get rid of poverty, so that the vehicle can get rid of poverty as soon as possible. To achieve the purpose, the invention adopts the following technical scheme: A vehicle assisted escape method comprising the steps of: S1, monitoring the running state of a vehicle in real time; s2, judging whether the vehicle is in a slipping state, if so, carrying out the next step, and if not, returning to the step S1; s3, the driver judges the getting-out position and marks the getting-out position on a control system of the vehicle; S4, the control system prompts a driver to rotate the steering wheel within a set angle range, and the driver controls the vehicle to back and advance within a set distance until the vehicle moves to the escaping position; s5, the control system controls the vehicle to run at a set speed at a constant speed, and the escape is completed. Further, in the step S2, when the difference between the running speed of the vehicle and the vehicle speed corresponding to the rotation speed of the driving wheel is within the set difference range, the vehicle is regarded as being in a slip state. Further, the rotation speed of the driving wheel is detected by a speed sensor provided on the vehicle. Further, the set difference range can be calibrated. Further, an alarm system is arranged in a cab of the vehicle and is in communication connection with the control system, and when the vehicle is judged to be in a slipping state, the alarm system gives an alarm to prompt a driver. Further, the alarm system comprises a voice broadcasting system, a light prompting system and/or a text prompting system. Further, in the step S4, when the angle of the steering wheel rotated by the driver is not within the set angle range, the control system prompts the driver through the alarm system. Further, in the step S4, when the vehicle backs up to the set distance, the control system prompts the driver to brake through the alarm system. Further, in the step S4, when the vehicle advances to the set distance, the control system prompts the driver to brake through the alarm system. A vehicle comprising a control system that assists in getting rid of a vehicle using a vehicle assist getting rid of trap method as described above. The invention has the beneficial effects that: According to the auxiliary escape method for the vehicle, the state of the vehicle is monitored in real time, when the vehicle is in a slipping state, a driver gets off the vehicle to judge the escape position, then the escape position is marked on a control system of the vehicle, the control system plans and prompts the driver to drive a steering wheel within a set angle range, the vehicle is controlled to move backwards and forwards within a set distance until the vehicle moves to the escape position, and the control system controls the vehicle to travel at a set speed at a constant speed to finish escape. By the method, the driver can be prevented from blindly operating according to inertia, the control system is used for reminding and indicating the action of the driver, the driver can be assisted to get rid of the trapping, and the vehicle can get rid of the trapping as soon as possible. The vehicle provided by the invention comprises a control system, wherein the control system adopts the vehicle auxiliary escaping method to assist the vehicle in escaping. The vehicle can assist the driver to get rid of the trapping, so that the vehicle can get rid of the trapping as soon as possible. Drawings FIG. 1 is a flow chart of a method for assisting in getting rid of poverty in a vehicle according to the present invention. De
