What is DAS-by-wire technology firms active steering?

1

What is?

no longer rely on the traditional mechanical connection, but instead the steering system is fully controlled by an electronic signal.

advantages

· Direct digital signal input, the system does not cause mechanical parts steering delay , better steering precision and fast. · With the removal of the mechanical connection, the steering wheel will not be receiving the face of the impact of the wheels, for better comfort from the ground. · According to the custom adjustment, you can change the steering wheel and the steering ratio, in order to achieve the purpose of personalized driving.

Did you know?

· flu road surface conditions of the DAS system to collect data by the sensor and wheel hop, road feel even when playing back the driving direction and the intensity of the analog feedback through the steering actuator. • There is no mechanical connection, when a vehicle collision, the steering column possibility of intrusion is also reduced, vehicle safety is also improved.
· transmission section retains the mechanical transmission, when a failure of the electronic system is powered off, the clutch is automatically closed, the driver can normally drive the vehicle.

Principle

DAS active steering wire steering system with the conventional configuration is similar to the system configuration, but also by the steering wheel, steering column, steering gear components. Except that it more than three sets of the electronic control unit ECU, the operation of the steering feedback device, the clutch wheel. ECU three computers to pass a signal to turn the steering wheel in accordance with three motors, which then sets the motor and controlling the rotational speed of the wheel angle, a set of force feedback motors to simulate a road surface, in addition to leaving a set of mechanical structures Preparation of the three groups as a backup when the ECU malfunction occurred.

the DAS system can maintain the system in conjunction with a lane, when the vehicle deviates from the lane as the first found, DAS system will be carried out according to road conditions to adjust the angle of the wheels, the vehicle will remain in the middle lane, reducing the risk of the vehicle deviates from the lane.
