Paltorc Smart Crank

The Smart Crank is a new method of detecting and recording biking movements, speed, crank angle and pedaling force. The PAS (pedal assist system) is built around the above exercise data. Paltorc Bike APP collects and store the exercise data after each pedaling cycle. At the same time the Bike APP also collect the health data from the wearable health gadgets such as watches and rings. The environment data (i.e. GPS, weather etc.) are also collected and stored in the smart phone. All of the log data files stored in the smart phone can be sent out by email or stored in the cloud.

Paltorc Smart Crank – CAN-Bus Version

Paltorc Smart Crank Features

Two Different Smart Crank Implementations:

  • Current Smart Crank Production Version - Send Throttle Voltage to E-Bike Motor Controller.

  • Send angle, speed, torque / weight and  gyro / accelerator, CAN-Bus Data to E-Bike Motor Controller.

  • Right Crank always synchronizes with Left Crank

  • For Cost Concern only Left Smart Crank is implemented

  • Right Crank Data is estimated by Left Crank

  • Paltorc APPs support both implementations

New versions of Paltorc Apps can support new version(I/O Adapter Board) and old version(CAN-Bus version)

Paltorc App Features:

  • Make riding more interesting

  • Collect exercise, health and environmental (GPS, weather) data

  • Generate Health & Exercise Big Data and summaries

  • Conduct remote service/diagnosis

  • Remote firmware update

  • All of Paltorc APPs can support the ebike CAN Bus system with or without smart crank installed.

  • If there is no smart crank installed, additional CAN-BLE board is required.

  • Customers Data Base

  • Health, Exercise and Environment data correlation report

  • Advertisement can be plugged during APPs usage

  • Build Social Networking by e-mailing

Paltorc's Smart Crank provides several features that other speed sensors and torque sensors cannot provide.

In addition to torque and speed sensors, we also provide:

  • Angle, we use the accelerator on the crank to provide the angle position of the crank and the position of the pedal at any moment. You can judge whether the left foot or the right foot is exerting force. You can also find the maximum output value of each pedaling cycle according to the angle.

  • Because there are Gyroscopes and Accelerators on the crank, the angular velocity will change drastically during a collision. Even when the E-bike is tipping, the changes in the gyroscope and accelerator can show the E-bike's tilt and unexpected conditions and provide warnings.

  • In the E-bike rental market, due to external damage or theft, the E-bike movement caused the Gyroscope and Accelerator to be in an incorrect state. It will also trigger a warning from the remote monitoring center.

  • Paltorc has developed several APPs to record all exercise, health, geographical, and weather conditions and provide summary reports.

  • At the same time, we can also use our APPs to record the E-bike's climbing conditions and slope, and use Bluetooth and CAN-Bus to provide the E-bike's slope to the motor controller for reference.

CAN-Bus Digital Throttle

Two existing CAN-Bus System Solutions

Can work with two different CAN-Bus protocols:

  • Paltorc CAN-Bus Protocol is available in web site

  • CAN-Bus smart crank prototype can work with CAN-Open devices

  • Can be modified to work with any other CAN-Bus protocols standards
