Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0023] The present application provides a vehicle steering system and a vehicle, aiming to solve the problems of complex steering and safety risks of existing vehicles.

[0024] The vehicle steering system is used to control the steering of the vehicle, such as figure 1 As shown, the vehicle steering system 100 includes a control system 110 and a rear wheel hydraulic steering system 120. The control system 110 controls the rear wheel hydraulic steering system 120 to realize that the size of the rear wheel rotation angle and the steering direction are based on the size of t...

Abstract

The invention discloses a vehicle steering system and a vehicle. The vehicle steering system comprises a rear wheel hydraulic steering system and a control system, and the control system controls the rear wheel hydraulic steering system to realize self-adaptive rotation of the rear wheel steering angle and the steering direction according to the front wheel steering angle and the steering direction; the rear wheel hydraulic steering system comprises a hydraulic power source and a hydraulic control module, and further comprises a centering cylinder and a steering power cylinder; the control system controls the hydraulic control module and the hydraulic power source to work according to the vehicle state information, high-pressure oil is provided for the steering power cylinder and the centering cylinder, ordered actions of the steering power cylinder and the centering cylinder are achieved, and a vehicle working mode corresponding to the vehicle state information is completed. According to the system, rear wheels are controlled to steer through electric control hydraulic pressure, and the rear wheels correspondingly rotate by a certain angle at a low speed according to the steering angle of front wheels, so that the turning diameter is reduced, and the vehicle trafficability is improved. Operation is easy, and operation is safe and reliable.

Description

technical field [0001] The present application relates to the field of vehicle control, in particular to a vehicle steering system and a vehicle. Background technique [0002] In the vehicle steering system and vehicles, due to the long wheelbase of large vehicles, the turning diameter is large during the turning process, which affects the maneuverability of the vehicle, and the steering efficiency is low, and even cannot be turned to pass in a small space. Therefore, allowing the rear wheels to participate in the steering can greatly reduce the turning diameter of the vehicle and improve the maneuverability of the vehicle. [0003] At present, domestic heavy-duty vehicles adopt follow-up steering technology. When the rear wheels are subjected to lateral force, the wheels will deflect at an angle to help the vehicle turn. The electro-hydraulic all-wheel steering technology is used in the prior art. Although the all-wheel steering system using this technology can switch betw...
