The present disclosure relates to a control method, device and vehicle for assisting steering, which relate to the field of vehicle control and are applied to vehicles. The method includes: when the vehicle satisfies a first preset condition, determining the first torque and the second torque according to the depth of the accelerator pedal of the vehicle Two torques, the first torque is controlled to be applied to the outer wheel of the vehicle, and the second torque is controlled to be applied to the inner wheel of the vehicle, the inner wheel is the driving wheel on the same side as the steering direction of the vehicle, and the outer wheel is the driving wheel on the opposite side to the steering direction Driving the wheels, the direction of the first torque is opposite to the direction of the second torque. The present invention effectively assists the steering of the vehicle without adding additional control mechanisms, has simple control, wide application range, low cost, can reduce the steering radius of the vehicle, and improves the operability of the vehicle.
Description
technical field [0001] The present disclosure relates to the field of vehicle control, in particular, to a control method, device and vehicle for assisting steering. Background technique [0002] In related technical fields, with the increasing number of automobiles in our country, the driving and parking environment of vehicles is becoming more and more complicated. In order to ensure the safety of vehicles, people have higher and higher requirements for the steering performance of automobiles. The improvement of steering performance is mainly realized by the steering control system on the vehicle. In the prior art, the steering control system of the vehicle determines the torque applied to the driving wheels through the depth of the driver's stepping on the accelerator pedal and the angle of the steering wheel. Usually, it is only applicable to a single driving mode, and the scope of application is small and the versatility is not good. powerful. If it is necessary to co...
