Abstract:
An anti-lock braking system (ABS) calculates driven wheel speed without any sensors on the driven axle assembly. A powertrain control module (PCM) receives signals from an output shaft speed (OSS) sensor and adds the speed and axle ratio information to a control network bus. Access to the CAN bus is provided to enable calculation of the rear wheel speed based on such information so that ABS may implement anti-lock braking functionality by taking into account such information.
