Abstract

The invention provides a power-assisted steering system and a vehicle. The power-assisted steering system includes: a motor, a first steering pump provided with a rotating shaft, a first oil inlet and a first oil outlet, a connecting piece respectively connected with the motor and the rotating shaft, an oil tank connected with the first oil inlet, and a steering gear connected with the first oil outlet. In the invention, the motor is mechanically connected with the first steering pump, and the motor rotates to drive the first steering pump to work. Due to the fact that the motor has inertia, even if the motor is powered off, the motor can still continue to rotate in a follow-up period of time due to inertia, the rotating shaft is driven to rotate, the first steering pump is driven to work, the situation that the steering pump cannot work due to the fact that the whole vehicle is powered off is avoided, and the safety of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the field of vehicle structures, in particular to a power steering system and a vehicle. Background technique [0002] In the prior art, when a specific fault occurs in the vehicle, the vehicle controller will delay power off for 30 seconds to ensure that the vehicle has power steering within 30 seconds to avoid failure of the power steering. [0003] However, this solution reduces the active safety of the vehicle. For example, when an emergency failure such as battery burning occurs in the vehicle, it is necessary to immediately cut off all Class B high-voltage power (high-voltage circuits greater than 60 volts), and it cannot be cut off after a delay of 30 seconds. Make sure the vehicle has power steering within 30 seconds. Contents of the invention [0004] In view of this, the present application proposes a power steering system and a vehicle, which can at least solve the technical problems in the prior art that the stee...
