Car steering device

Abstract

The invention discloses a car steering device, and relates to the field of car steering. The car steering device comprises a steering helm, a steering wheel shifting device, a torque sensor, an angle sensor, a control unit and a steering executing device, wherein the steering helm comprises a steering wheel and a steering shaft connected with the steering wheel, the steering wheel shifting device comprises a shifting rod and a position fixing device, the shifting rod is fixed to a car frame, the position fixing device is installed on the shifting rod fixedly or along the shifting rod in a shifting and locking mode, the torque sensor is used for detecting torque acting on the steering wheel, the angle sensor is used for detecting the rotation angle of the steering wheel, the control unit receives steering wheel torque signals and steering wheel rotation angle signals to carry out analysis and processing to generate steering control codes, and the steering executing device receives the steering control codes and controls the turning direction of wheels. The car steering device enables a left helm and a right helm to be switched easily and flexibly, and reduces the cost for developing a left-right helm car.

Description

technical field [0001] The invention relates to the field of automobile steering, in particular to an automobile steering device. Background technique [0002] In different countries, the setting of the cockpit is different. The position of the cockpit is divided into left rudder (the steering wheel is on the left side of the front row of the cockpit) and right rudder (the steering wheel is on the right side of the front row of the cockpit at this time). [0003] Vehicles in the Commonwealth of Nations generally have the steering wheel on the right. This is because the traffic rule is to drive on the left and turn left first. In order to have a good view of the car and see clearly when meeting cars, the driver needs to sit on the right. Hong Kong and Japan have also followed this rule. [0004] Conversely, in countries and regions such as China and the Americas, the steering wheel is on the left. This is because the traffic rule is to drive on the right, so the driver sit...

Problems solved by technology

However, it will be very inconvenient for a vehicle with a right steering wheel to drive in a country where the vehicle drives on the right: the driver's vision will be very poor, and the blind spot on the left side will be very large. Vehicles with left-hand steering wheels are also inconvenient in countries where vehicles drive on the left

[0006] From the perspective of automobile manufacturers, the design of single-steer vehicles is difficult to meet the needs of consumers all over the world, but the R&D cost required to install two sets of steering wheel steering devices in the front row of the car or to develop left and right rudders at the same time is relatively high, and in the existing technology Among them, it is cumbersome and costly to adjust the steering wheel position of the left and right steering cars before the car leaves the factory
