2.4.2.1.1. Abnormal shutdown protection
In order to protect the safety of the user while riding, if the server sends the RTO.Lock
command to lock the scooter by mistake, the ECU will not immediately lock the scooter after
receiving the instruction, but will stop the drive motor and let the scooter slide without power.
Wait for the speed <2m/h to lock the scooter.
2.4.2.1.2. Prevent the car from flying out
In order to prevent the user from accidentally pressing the accelerator and brake lever during
the unlocking period, which may cause the user to be unable to ride after being unlocked, or the
scooter will start immediately after sliding, OKAI ECU will show 18E, 19E, 20E on the display to
prompt the user to release the accelerator and brake
2.4.2.1.3. Start mode: assist start mode
In order to prevent the user from accidentally pressing the accelerator, causing the scooter to
start suddenly. The ECU of OKAI scooters adopts a power-assisted start mode, which requires the
user to kick backwards with their feet to make a forward push. When the speed of the scooter
reaches 4km/h, the scooter can be started.
2.4.2.1.4. Electronic Brake Function
In order to improve the stability and safety of the brakes, the ECU of the OKAI scooter has an
electronic brake function, which can ensure that the scooter is braked in time when the mechanical
brake is damaged. In addition, the electronic brake enhances the braking force, and in conjunction
with the mechanical brake, the braking force can provide a timely braking force for the scooter. You
can also send commands through IOT to adjust the gear position of the electronic brake (0-10 gears)
2.4.2.1.5. Self-Detection When power on
After receiving the unlocking command, the ECU of OKAI Scooter will automatically detect
whether the vehicle wire is short-circuited, whether the MOS is damaged, etc., and if an
abnormality is detected, the error code will be showed on the display and reported to the IOT
