Note
Make sure to jack the vehicle up when forcibly driving the motor in the rear steering link assembly using the Global TechStream (GTS).
A low inertia, low noise and high output brushless type motor is used.
The rear steering link assembly operates based on the steering amount calculated by the front steering control ECU, in accordance with the signal from the rear steering control ECU.
The stroke sensor detects the absolute position of the rear wheel turning angle using a resolver sensor.
Gears are provided on the edge of the rod and stroke sensor. The movement of the rod rotates the stroke sensor, enabling the rod position to be detected.
Motor and Reduction Mechanism
The motor is located on the same axis as the rear steering rod and consists of a rotation angle sensor, rotor and stator.
A planetary gear is used for the reduction mechanism. A sun gear is located at the end of the rotor to reduce the rotation speed of the motor.
The rotation of the carrier is transmitted to the rear steering nut. The rotation of the rear steering nut moves the rear steering rod, steering the rear wheels.
The shape and location of the rear steering nut have been optimized, ensuring high efficiency and strength, and enhanced holding force in reaction to opposing forces from the road surface.
