PAWS all-wheel precision steering technology is mainly used in Acura's flagship model RLX. The core of the system lies in the electronically controlled actuators located in the left and right rear suspensions. By controlling the powertrain, EPS, VSA, etc. By analyzing the provided driving information, the toe angles of the two rear wheels can be adjusted independently, with a maximum adjustment range of about 2 degrees.
The main functions are as follows:
1. During straight driving and emergency braking, the toe-in value of the two rear wheels is positive, that is, the front ends of the two rear wheels are inward. It closes up to form an "inner figure" to enhance the stability of the vehicle's straight-line driving.
2. When turning or making a U-turn, the two rear wheels point in the opposite direction to the front wheels, helping to reduce the turning radius, while reducing the possible understeer of a front-wheel drive vehicle and improving the vehicle's cornering performance.
3. When merging at high speed, the left and right rear wheels point in the same direction as the front wheels, which improves the following ability of the rear of the car and makes the merging action more agile and stable.
