Motor shakes too
much
PID parameter mismatch
Connect the host computer to re-
adjust the PID parameters. First
adjust the I parameter to the minimum,
then reduce the P parameter, increase
the D parameter appropriately, and then
increase it appropriately

The vehicle
vibrates
PID parameter mismatch
Reduce the I parameter and
appropriately increase the P
parameter

Acceleration and
deceleration are
too severe
Acceleration and deceleration
ramp time is too small
Properly increase the acceleration and
deceleration ramp time
