Output Shaft Speed Sensor
The ECVT transmission has a dedicated secondary speed sensor located in the differential housing. This sensor is a Hall effect sensor and produces a pulse train of approximately 73000 pulses per mile. The sensor allows for more precise calculation of transmission output speed that is used in the control strategy systems.
The secondary speed sensor is located so that the sensor tip is close to the crown wheel of the differential. By sensing the crown wheel, the signal is not affected by the different wheel speed signals when the vehicle is cornering.
