Problems solved by technology
[0004] In the above method, due to the sudden increase in resistance after a tire blowout, the vehicle speed will suddenly drop. When driving at high speed, accidents such as rear-end collisions are likely to occur.
On the other hand, increasing the rotation speed of the wheel on the side of the puncture requires a high-power motor for the vehicle, resulting in extremely high vehicle costs, and the above-mentioned solution is only applicable to four-wheel independent drive vehicles. The latter scheme is not feasible; and the driving force and braking force on the side with a puncture and the side without a puncture are controlled simultaneously, so there are many control objects and the algorithm is complex

The invention discloses a vehicle tire burst control method and device, and a vehicle. The vehicle tire burst control method comprises the steps: obtaining tire pressure information; judging whether tire burst occurs or not based on the tire pressure information; and during tire burst, adjusting a vehicle body height difference to enable a tire burst side vehicle body height to be higher than a non-tire-burst side vehicle body height, increasing an input torque of tire burst side wheels, and reducing the input torque of non-tire-burst side wheels. According to the method provided by the invention, by adjusting the vehicle body height difference between the two sides, increasing the input torque of the tire burst side wheels and reducing the input torque of the non-tire burst side wheels, the vehicle body can be effectively prevented from rolling over through a synergistic effect in multiple aspects, a vehicle speed cannot be suddenly decreased, and a rear-end collision risk is prevented.
Description
technical field [0001] The present application belongs to the technical field of vehicle safety control, and in particular relates to a control method, device and vehicle for vehicle tire blowout. Background technique [0002] When a tire blows out, the vehicle is prone to violent yaw, which will lead to serious safety accidents if not handled properly. [0003] In the related art, in order to prevent severe yaw in the direction of travel of the car when the tire is blown out, the speed of the unexploded wheel will be reduced, and the speed of the unexploded wheel on the side of the blown tire will be increased to maintain the balance of the car. [0004] In the above method, due to the sudden increase in resistance after the tire blowout, the speed of the vehicle will suddenly drop. When driving at high speed, accidents such as rear-end collisions are easy to occur. On the other hand, increasing the rotation speed of the wheel on the side of the puncture requires a high-po...
